issue with incoming an outgoing calls with a CUCM and 2901 CUBE ISR

[bruno zenkri]

Hi all,

I'm trying to configure ISR 2901 CUBE with a SIP Trink ISP, and I have several isues: I'm unable to make calls or receive one. I can see that I'm registerd with my ISP, but when I make a call from inside to outside, I've got a busy tone, And when I try to connect from an outside phone to a DID phone, I get a IVR message from my headline (even not from my DID).

I've tried many things, but I don't have any more ideas...

Can someone help me?

I attach the show run and the debug ccsip file

Thanks

Best Regards

Bruno Z.

Couple of things:

Change dial-peer 11's dtmf to rtp-nte (This shouldnt affect calling but want to clear it out)

You have session transport set as UDP, did you make the same change on the CUCM side? Under SIP trunk security profile, change the outgoing transport as UDP and assign the security profile that you modified to the SIP trunk to the CUBE in CUCM.

It looks like you have a SIP provider that needs to route through the internet? Or does Gig0/1 need to be no shut?
