Make sure that your bind interface is configured correctly on the router.
If you aren't getting a reply for register message then its getting blocked
and not reaching the other end.

I did not have the bind in the config, added but still no joy

Hi All;

Thanks for the assistance!

I don't know what was blocking the register but I used  another interface to direct connect the sip trunk and it worked.

Good afternoon,   I know this is an old post but do you by chance have a sample config of your Cisco 2821 bound to an external SIP trunk provided by an ISP.  I am currently setting up a Cisco 2821 that I have for testing in a lab environment and am having an issue connecting back to the SIP IP provided by my ISP.  Thank you.

[Roger Kallberg]

I would advise you to create your own post instead of posting your question on an old post that is marked as answered.

You do the bind of interface on the dial peer(s) for it to know what interface to use for the communication with your SP. The rest is managed by the routing table on the router. There is no thing as such as binding to a SIP trunk.

[childebrecht]

I apologize,

The only reason I posted back in this post was hoping that the original
poster was still active and would be able to provide a sample of the config
they used since they were in the same situation as I am with configuring a
SIP trunk provided by a cable internet ISP.

Look at this document for how to bind media and control traffic to a specific interface. https://www.cisco.com/c/en/us/support/docs/voice/ip-telephony-voice-over-ip-voip/211306-In-Depth-Explanation-of-Cisco-IOS-and-IO.html
