I try to make my e75 work on my cico call manager 6.1. Registration is OK and I can receive calls on it however I cannot make any call and I get the following message: unable to make internet call due to recipient's restrictions.
A wireshark trace lets appear a "400 bad request malformed/missing URL" message from my CUCM
I have differents phones on my cucm, sip and sccp and they work fine, with the same profile...
I have upgraded my cucm from 6.1.1 to 6.1.3 but it steal the same problem. However I tried to register on a simple Brekeke sip server and it's working fine.
Any of you have an idea why I cannot make call with my CUCM cisco ?
