Configuring CM 4.2.3 SIP Trunk for IXC

Unanswered Question

I've configured a SIP trunk for an IXC and am recieving an error from the carrier that there is an error in my configuration. The SIP trunk itself is pretty straightforward except for a source port set to 5061 (5060 is already taken by another device.) Since I'm getting an error from the IXC side, I assume that connectivity itself isn't an issue. Can someone suggest something I should look for?

so after u are sure on IP connectivity with the IXC, i would suggest checking two things:

codec at both IXC and ur side

and make sure u r sending udp (under to sip security profile)

After a packet sniff I found out what the issue was. The IXC I am using does not support CallManager so you will likely not be able to get configuration support from them (they are very Asterisk-friendly.) All you have to do is configure the Caller ID DN field in the Outbound Calls section of the SIP trunk with's Peer Name field. That's pretty much it. When the trunk tries to build a connection to the IXC for the outbound call, it uses and authorization format of [email protected] for authentication. When you log into your IXC peer you can configure the Outbound Caller ID there.

Oh, and when you set up your DTMF mode, choose "auto" from the drop-down box.
