I'm working with a uc500.
I'm trying to implement a trunk sip to a gsm gateway. I made the test with the gsm gateway and a sip client on my pc without problem.
When I redirect the call to the uc500 I can't do any call towards a mobile phone. I test the outgoing dial plan without any problem.I don't know exacly the problem.
May you help me?
I attached sip debug
