1.  Overview

What is DGW-100XR?

OpenVox T1/E1 Gateway is an open source asterisk-based VoIP Gateway solution for operators and call centers. It is a converged media gateway product. This kind of gateway connects traditional telephone system to IP networks and integrates VoIP PBX with the PSTN seamlessly. With friendly GUI, users may easily setup their customized Gateway. Also secondary development can be completed through AMI (Asterisk Management Interface). The DGW-100XR could support two power supply and DGW-100X series gateway support one power supply.

It is developed with a wide selection of codecs and signaling protocol, including G.711A, G.711U, G.729, G.722, G.723 and GSM. It supports PRI/SS7/R2 protocol. OpenVox T1/E1 Gateway has good processing ability and stability and we provides 1/2/4 T1/E1 interface for your choice. The T1/E1 gateway will be 100% compatible with Asterisk, Elastix, trixbox, 3CX, FreeSWITCH SIP server and VOS VoIP operating platform.

Main Endpoint Settings

You can click button to add a new SIP endpoint, and if you want to modify existed endpoints, you can click button.

 

There are 3 kinds of registration types for choose. You can choose Anonymous, Endpoint registers with this gateway or This gateway registers with the endpoint.

You can configure as follows:

If you set up a SIP endpoint by registration “None” to a server, then you can’t register other SIP endpoints to this server. (If you add other SIP endpoints, this will cause Out-band Routes and Trunks confused.)

                                      Figure 4-1-2 None Registration

For convenience, we have designed a method that you can register your SIP endpoint to your gateway, thus your gateway just work as a server.

                                       Figure 4-1-3 Endpoint Register with Gateway

Also you can choose registration by “This gateway registers with the endpoint”, it’s the same with “None”, except name and password.

Transport

This sets the possible transport types for outgoing. Order of usage, when the respective transport protocols are enabled, is UDP, TCP, TLS. The first enabled transport type is only used for outbound messages until a Registration takes place. During the peer Registration the transport type may change to another supported type if the peer requests so.

Whether or not to add;’ user=phone’ to URIs that contain a valid phone number.

Add Q.850 Reason Headers

Whether or not to add Reason header and to use it if it is available.

Honor SDP Version

By default, the gateway will honor the session version number in SDP packets and will only modify the SDP session if the version number changes. Turn This option off to force the SDP session version number and treat all SDP data as new data. This is require for devices that send non-standard SDP packets (observed with Microsoft OC S).By default

This option is on.

Allow Transfers

Whether or not to globally enable transfers. Choosing ‘no’ will disable all transfers (unless enable in peers or users). Default is enabled.

Allow Promiscuous Redirects

Whether or not to allow 302 or REDIR to non-local SIP address .Note that promiscredir when redirects are made to the local system will cause loops since this gateway is incapable of performing a ‘hairpin’ call.

Max Forwards

Setting for the SIP Max-Forwards header (loop prevention).

Send TRYING on REGISTER

Send 100 Trying when the endpoint registers.

Error Correction

Max Datagram

In some cases,T.38 endpoints will provide a T38FaxMxDatagram value (during T.38 setup) that is based on an incorrect interpretation of the T.38 recommendation, and result in failures because Asterisk does not believe it can send T.38 packets of a reasonable size to that endpoint (Cisco media gateway are one example of this situation).In these cases, during a T.38 call you will see warring messages on The console/in the logs from the Asterisk UDPTL stack complaining about lack of buffer space to send T.38FaxMaxDatagram value specified by the other end[point, and use a configured value instead.

Fax Detect

FAX detection will cause the SIP channel to jump to the ‘faX’ extension (if exists) based one or more events being detected. The events that can be detected are an incoming CNG tone or an incoming T.38 re-INVITE request.

Allowed characters

Registration

Whether this endpoint will register to this gateway or this gateway to the endpoint.

Hostname or IP Address

IP address or hostname of the endpoint or ‘dynamic’ if the endpoint has a dynamic IP address. This will require registration.

Notice: If the input here is hostname and your DNS has changed, you must reboot asterisk.

Auth

Authentication method for connections

Transfer

Disable or not IAX2 native transfer

Trunk

Use IAX2 trunking with this host

Qualify

Whether or not to check the endpoint’s connection status.

Qualify Smothing

Use an average of the last two PONG result to reduce falsely detected LAGGED host. The default is ‘no’.

Qualify Freq Ok

How frequently to ping the peer when everything seems to be OK, in milliseconds.

Qualify Freq not Ok

How frequently to ping the peer when it’s either;

LAGGED or UNAVAILABLE, in milliseconds.

Port

The port number the gateway will connect to at this endpoint.

Encryption

Enable IAX2 encryption. The default is no.

Force Encryption

Force encryption insures no connection is established unless both sides support encryption. By turning this option on, encryption is automatically; turned on as well. The default is no.

Trunk Max Size

Defaults to 128000 bytes, which supports up to 800; calls of ulaw at 20ms a frame.

Trunk MTU

With a large amount of traffic on IAX2 trunk, there is a risk of bad voice quality when allowing the Linux system to handle fragmentation of UDP packets.

Depending on the side of each payload, allowing the OS to handle fragmentation may not be very efficient. This setting sets the maximum transmission unit for AIX2 UDP trunking. The default is 1240 bytes which means if a trunk’s payload is over 1240 bytes for every 20ms it will be broken into multiple 1240 bytes messages. Zero disables this functionality and let’s the OS handle fragmentation.

Trunk Frequency

How frequently to send trunk msgs (in ms). This is 20ms by default.

Trunk Time Stamps

Should we send timestamps for the individual sub_frames within trunk frames? There is a small bandwith use for these (less than 1kbps/call), but they ensure that frame timestamps get sent end-to-end properly. If both ends of all your trunks go directly to TDM, _and_your trunkfreq equals the frame length for your codecs, you can probably suppress these. The receiver must also need to have it enabled.

Min. RegExpire

Local Network

Format:192.168.0.0/255.255.0.0 or 172.16.0.0./12. A list of IP address or IP ranges which are located inside a NATed network. This gateway will replace the internal IP address in SIP and SDP messages with the external IP address when a NAT exists between the gateway and other endpoints.

Local Network List

Local IP address list that you added.

Subscribe Network Change Event

Through the use of the test_stun_monitor module, the gateway has the ability to detect when the perceived external network address has changed. When the stun_ monitor is installed and configured, chan_sip will renew all outbound registrations when the monitor detects any sort of network change has occurred. By default this option is enabled, but only takes effect once res_stun_monitor is configured. If res_stun_monitor is enabled and you wish to not generate all outbound registrations on a network change, use the option below to disable this feature.

Match External Address Locally

Only substitute the exeternaddr or externhost setting if it matches

Dynamic Exclude Static

Disallow all dynamic hosts from registering as any IP address used for staticly defined hosts .This helps avoid the configuration error of allowing your users to register at the same address as a SIP provide.

Externally Mapped TCP Port

The externally mapped TCP port, when the gateway is behind a static NAT or PAI

External Address

The external address (and optional TCP port) of the NAT. External address=hostname [:port] specifies a static address[:port] to be used in SIP and SDP messages. Examples: External address=12.34.56.78 External address=12.34.56.78.9900

 

 

 

External Hostname

The external hostname (and optional TCP port) of the NAT.

External Hostname=hostname[:port] is similar to

“External address”. Examples:

External Hostname=foo.dyndns.net

Hostname Refresh Interval

How often to perform a hostname lookup. This can be useful when your NAT device lets you choose the port mapping, but the IP address is dynamic. Beware, you might suffer from service disruption when the name server resolution fails.

Strict RFC Interpretation

Check header tags, character conversion in URIs, and multiline headers for strict SIP compatibility(default is yes)

Send Compact Headers

Send compact SIP headers

SDP Owner

Allows you to change the username filed in the SDP owner string.
This filed MUST NOT contain spaces.

Disallowed SIP Methods

When a dialog is started with another SIP endpoint, the other endpoint should include an Allow header telling us what SIP methods the endpoint implements. However, some endpoint either do not include an Allow header or lie about what methods they implement. In the former case, the gateway makes the assumption that the endpoint support all known SIP methods. If you know that your SIP endpoint does not provide support for a specific method, then you may provide a list of methods that your endpoint does not implement in the disallowed_ methods option. Note that if your endpoint is truthful with its Allow header, then there is need to set this option.

Shrink Caller ID

The shrinkcallerid function removes '(', ' ', ')', non-trailing '.', and '-' not in square brackets. For example, the caller id value 555.5555 becomes 5555555 when this option is enabled. Disabling this option results in no modification of the caller id value, which is necessary when the caller id represents something that must be preserved. By default this option is on.

Maximum Registration Expiry

Maximum allowed time of incoming registrations and subscriptions (seconds).

Minimum Registration Expiry

Minimum length of registrations/subscriptions (default 60).

 

 

Default Registration Expiry

 

Default length of incoming/outgoing registration.

Match Auth Username

If available, match user entry using the 'username' field from the
authentication line instead of the 'from' field.

Realm

Realm for digest authentication. Realms MUST be globally unique according to RFC 3261. Set this to your host name or domain name.

Use Domain as Realm

Use the domain from the SIP Domains setting as the realm. In this case, the realm will be based on the request 'to' or 'from' header and should match one of the domain. Otherwise, the configured 'realm' value will be used.

Always Auth Reject

When an incoming INVITE or REGISTER is to be rejected, for any reason, always reject with an identical response equivalent to valid username and invalid password/hash instead of letting the requester know whether there was a matching user or peer for their request. This reduces the ability of an attacker to scan for valid SIP usernames. This option is set to 'yes' by default.

Authenticate Options Requests

Enabling this option will authenticate OPTIONS requests just like INVITE requests are. By default this option is disabled.

Allow Guest Calling

Allow or reject guest calls (default is yes, to allow). If your gateway is connected to the Internet and you allow guest calls, you want to check which services you offer everyone out there, by enabling them in the default context.

Options

Definition

Jitter Buffer

Global default as to whether you want the jitter buffer at all

Force Jitter Buffer

In the ideal world, when we bridge VoIP channels we don’t want to jitter buffering on the switch, since the endpoints can each handle this. However, some endpoints may have poor jitter buffers themselves, so this option will force to always jitter buffer, even in this case.

Max Jitter Buffers

A maximum size for the jitter buffer

Resyncthreshold

When the jitter buffer notice a significant change in delay that continue over a few frames, it will resync, assuming that the change in delay was caused by a timestamping mix-up. The threshold for noticing a change in delay is measured as twice the measured jitter plus this resync threshold.

Max Jitter Interps

The maximum number of interpolation frames the jitter buffer should return in a row. Since some clients do not send CNG/DTX frames to indicate silence, the jitter buffer will assume silence has begun after returning this many interpolations. This prevents interpolating throughout a long silence.   

Jitter Target Extra

Number of milliseconds by which the new jitter buffer will pad its size. The default is 40, so without modification, the new jitter buffer will set its size to the jitter value may help if your network normally has low jitter, but occasionally has spikes.

Max Call Number

The ‘maxcallnumbers’ option limits the amount of call numbers allowed for each individual remote IP address. Once an IP address reaches its call number limit, no more new connections are allowed until the previous ones close. This option can be used in a peer definition as well, but only takes effect for the IP of a dynamic peer after it completes registration.

MaxCallNumbers_Nonvalidated

The ‘maxcallnumbers-nonvalidated’ is used to set the combined number of call numbers that can be allocated for connections where call token validation has been disabled. Unlike the ‘maxcallnumbers’ option, this limit is not separate for each individual IP address. Any connection resulting in a non-call token validated call number being allocated contributes to this limit. For use cases, see the call should be sufficient in most cases.

Dial Patterns that will use this Route

A Dial Pattern is a unique set of digits that will select this route and send the call to the designated trunks. If a dialed pattern matches this route, no subsequent routes will be tried. If Time Groups are enabled, subsequent routes will be checked for matches outside of the designated time(s).
Rules:
X matches any digit from 0-9
  matches any digit from 1-9
matches any digit from 2-9
[1237-9]  matches any digit in the brackets (example: 1,2,3,7,8,9)
wildcard: matches one or more dialed digits.
prepend:  Digits to prepend to a successful match.
If the dialed number matches the patterns specified by the subsequent columns, then this will be prepended before sending to the trunks.

prefix:   Prefix to remove on a successful match.
The dialed number is compared to this and the subsequent columns for a match.
Upon a match, this prefix is removed from the dialed number before sending it to the trunks.

match pattern:   The dialed number will be compared against the prefix + this match pattern.
Upon a match, the match pattern portion of the dialed number will be sent to the trunks

SDfR(Stripped Digits from Right): The amount of digits to be deleted from the right end of the number. If the value of this item exceeds the length of the current number, the whole number will be deleted.

RDfR( Reserved Digits from Right) :Designated information to be added to the right end of the current number.

StA(Suffix to Add):Designated information to be added to the right end of the current number.

Caller Name: What caller name would you like to set before sending this call to the endpoint. Native language charset is allowable, e.g. Chinese charset, Latin charset.

Forward Number

What destination number will you dial? 

This is very useful when you have a transfer call.

Failover Call Through Number

The gateway will attempt to send the call out each of these in the order you specify.

 

You can create various time routes and use these time conditions to limit some specific calls.

If you configure like this, then from January to March, from the first day to the last day of these months, from Monday to Thursday, from 00:00 to 02:00, during this time (meet all above time conditions), all calls will follow this route. And the time will synchronize with your Sever time.

                                                 Figure 5-1-5Change Rules

You can set your caller ID name and caller number as you like before sending the call to the endpoint. You can also configure forward number when you have a transfer call.

                                      Figure 5-1-6 Failover Call Through Number

You can add one or more “Failover Call Through Numbers”.

Groups

Sometimes you want to make a call through one port, but you don’t know if it is available, so you have to check which port is free. That would be troublesome. But with our product, you don’t need to worry about it. You can combine many Ports or SIP to groups. Then if you want to make a call, it will find available port automatically.

Auto Provisioning

Auto provisioning or auto-configuration is an easy, flexible and time-saving way to upgrade firmware and configurations for E1 gateways in mass deployment. With auto provisioning, all user information can be entered via the central ACS (Auto Configuration Server). ACS can be DHCP server or TFTP, HTTP and FTP server. It will not take effects immediately but in the next time system is power on. It could be postponed the execution of restart system also.

Note that system will not be upgrade the firmware and update configurations if the connection between ACS and gateway is disconnect.

 Preparation

The following should be prepared before anto provisioning being applied.

l  Enable the auto provisioning in gateway

l  The ACS has been prepared

l  The network between gateway and ACS is connected

 

 Configuring gateway

Usually, the feature is disabled before being on sale. To activate the auto provisioning function, please follow the procedures as below.

Provisioning example

After auto provisioning is enabled, the gateway will visit the Auto Configuration Server and download the updated files periodically based on the timer Check Interval (LOGS->System notice). By default, the timer is set as every hour. System will receive a message from ACS, like figure 7-4-3, and the message will be display in the system notice (LOGS->System Notice).

Auto provisioning will not take effects immediately but in the next time system is power on. It could be postponed the execution of restart system also.

       Now, an example of using Auto Provisioning will be given in the following.

  1. Activate the auto provision (TFTP) in ADVANCED-> Auto Provision like figure 7-4-4.

SNMP

Simple Network Management Protocol (SNMP) is an application–layer protocol, which is used to manage and monitor network elements and exchange management information between network devices. By default SNMP uses port 161 for communication.

Since the inception SNMP, it embraces three versions: v1, v2c and v3. V1 and v2c are the most implemented version of SNMP; v3 is target at the high security when compare to its older versions. The gateway support private SNMP MIBs (private enterprise number) to access.

 Verify SNMP

A powerful, indispensable and easy-to-use MIB browser is convenient for engineer/manager to manage SNMP enabled network devices and applications. In this session, Manage Engine MIB browser is selected. It allows user to issue SNMP requests to retrieve agent's data, or make changes to the agent. It is free tool for Windows, Mac and Linux.

(1). Get SNMP parameters via SNMP MIB browser. It’s supposed that Manage Engine MIB browser is installed perfectly. Figure 7-5-2 is the main interface of Manage Engine MIB browser.

Figure 7-5-2 Manage Engine MIB browser

And the field of Host, Port and Community are filled with 172.16.100.223, 161 and public respectively. Object ID is the node of SNMP MIBs, e.g. “.1.3.6.1.2.1.1.6.0” is system location and “.1.3.6.1.2.1.1.1.0” is system description.
