[cisco-voip] MOH and SRST With SIP trunk

[Granger, Simon]

Hello all again,

Thanks for all the comments regarding my last post.

We have a Sip trunk that can dial in and out, but as soon as the system goes into SRST mode, all the phones re-register, but when you phone the Sip trunk number it does not ring on the phone.

If you do a debug ccsip messages, you can see it trying to make contact with the Call manager servers. Any Thoughts?

Secondly, we use multicast MOH, and if you call IP Phone to IP Phone that works fine, but it does not work at all across the SIP Trunk.

Thanks
