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.
