Has anyone been able to connect Express Talk to a Cisco Unified Communications Manager? I've created a basic SIP device on the Cisco side and have verified that it works using X-Talk however I can't seem to get it going with Express Talk. I've got it to the point where it registers with the Cisco however when I try to call it the status comes up with 'Incoming connection does not support proper SIP codecs'. When I try to make a call it says 'Error. Other side said: Bad Request - Malformed/Missing URL' Any ideas?
