1 Published on Documentation ( Home > IP Trunk Assistant IP Trunk Assistant The IP Trunk Assistant page offers simplified IP trunk configuration. This page shows a list of IP trunk accounts created from this interface, with the capability to create, update and/or delete SIP/IAX trunks as well as the capability to enable/disable them. Before you start creating SIP trunks, ensure you verify the following: SIP ALG is disabled. Port forwarding is configured on your router. SIP Settings page has the correct NAT settings and external IP address. See External SIP Trunk - Configuration Checklist for details. To open the page, perform the following steps: 1. Open the UCx Web-based Configuration Utility 2. From the PBX tab, select IP Trunk Assistant Adding a New Account To add a new trunk account, perform the following steps: 1.

If registration based authentication is used for this trunk, then enter the user name and password that you received from the IP trunk provider If IP-based authentication is used for this trunk, these two fields are disabled 5. Optionally, you can enter the desired outbound caller ID number in the Outbound CallerID field 6. In the Host / IP field, check and update the value to match the far-end host IP address.

3 add a port number to the address suffixing with a colon followed by the port number. (e.g :5000) 7. Press the Save button to create the new account 8. The corresponding trunk for this account is automatically created and immediately enabled (there is no need to go to the PBX Configuration page to apply configuration changes). 9. You can view the details of the trunk created by going to PBX Configuration - Trunks page. When you select from the Trunk Provider drop down list, the corresponding configuration details for the selected provider or system are pre-filled with default values. These pre-configured values have been tested and verified by E-MetroTel. If a custom trunk provider is selected, then you will need to manually fill in the required fields. (For list of verified trunk providers, see SIP Trunk Configuration (verified SIP providers) page). If you decide to change some of the pre-configured defaults, please make sure you understand the purpose of the modified fields and values you entered. Configuration Details The following table provide a description of the fields in the Configuration Details box. Field Common Settings Description Type peer peer means this is a SIP entity to which UCx sends calls (e.g. a SIP provider). user means this is a SIP entity which places calls through UCx ((e.g. a phone which can place calls only) friend means the entity is both a user and a peer. Qualify yes yes means that the UCx system will periodically send a request that the other system identify itself. If there is no answer within 2 seconds,ucx will assume that the other system is down and stop sending calls to the system until it responds. Insecure port,invite port means to accept incoming calls even if they come from a port other than the one where calls are expected to come from. invite means to accept incoming calls even if they are not accompanied by the proper username and password. Most trunk providers require these settings. DTMF Mode rfc2833 rfc2833 is the most common method for sending DTMF. The other methods are inband and info. auto means to use rfc2833 if offered, inband otherwise. Technology SIP This is the protocol to use for this trunk, you can choose between SIP and IAX2.

4 Field Common Settings Description Can Reinvite nonat yes means to allow reinvites for the purpose of setting up direct media path. no means do not allow reinvites for the purpose of setting up direct media path. nonat means to alllow reinvites when local and deny reinvites when there is NAT. update means to use UPDATE instead of INVITE. Send RPID yes yes means to send the Caller ID on outgoing calls using the Remote-Party-ID header. If your outgoing calls are always rejected, you may want to set this to no. pai means that your system will send the Caller ID on outgoing calls using the "P-Asserted-Identity" header. If your outgoing calls have an incorrect Caller ID, you may want to use this setting. Trust RPID yes yes means to look at the Remote Party ID header for the Caller ID on received calls instead of the from field of the incoming call. DTLS-SRTP no To enable DTLS-SRTP for this trunk, the systems on both ends must support it and DTLS certificate is required. See DTLS Certificate for details. ICE no Enabling ICE support is recommended only in cases when there are issues with NAT traversal due to complicated multiple router configurations. See ICE support for details. Host / IP Hostname / IP address of the remote system that you are connecting to. Optionally, the SIP port number used by the host can also be included. Ex: dallas.voip.ms, :5068. Context from-trunk from-trunk means that incoming calls from this trunk will be treated as if they are coming from an outside line, and will be routed using the rules that you setup in the Inbound Routes Module. from-internal means that incoming calls from this trunk will be treated as if they were made by an internal phone, and will be routed directly to an extension number, a feature code, or through the outbound routes module. Disallow all The value all tells the system to not use any audio codecs unless they are expressly allowed in the Allow field. Allow ulaw,alaw Enter the codec(s) that are allowed. This takes effect only if Disallow is set to all. From User The value entered in this field replaces the Caller ID in the From Domain from field of the call. If the remote system expects the Caller ID to appear in the from field, you should leave this field blank. The value entered in this field replaces the domain name in the from field of the call.

5 You can use the IP Trunk Assistant page to manage configured IP trunk accounts: To delete an account, select the checkbox on the left side of the account list and press the Delete button To edit the account configuration data, select the Edit link in the Action column To enable and disable the account, select the Disable/Enable link in the Action column If your trunk provider does not appear in the Trunk Provider drop down list box, you can add accounts from other providers by selecting custom in the Trunk Provider field. Note that configuration changes made in the IP Trunk Assistant page will be propagated to the Trunks page. However changes made in the Trunks page will not be propagated back to the IP Trunk Assistant page. Hence it is recommended that you make your configuration changes from the IP Trunk Assistant page. The only changes you would make in the Trunks page are fields that do not appear under IP Trunk Assistant. Video Tutorial Last modified: 02/07/18 01:51 AM Copyright 2015 E-MetroTel Global Inc.
