SIP provider SRST BRI

[sebastiaanp]

We have configured a 2821 router with a SIP connection to a SIP provider. We want to configure SRST fall-back with a BRI interface. Outward dialing works but when we configure a dial-peer POTS with direct inward dial the SRST functions but the SIP connection failes. How to configure SRST with a SIP connection on a gateway?

Here the config without:

dial-peer voice 1 pots

incoming called-number .

direct-inward-dial

After configuring this dial-peer SIP does not function!

Hmmm. Where is the call originating from?

Can you post the output from "show dial-peer voice summary"?

Can you "debug voice dialpeer inout" and "debug ccsip messages" and post the output?

I guessing either it's hitting the wrong dial-peer or the ANI in the SIP message is different and causing the INVITE to be rejected. Or, something else entirely, but the debugs should help point us in the right direction.
