I've received my Com-on-Air DECT card this morning and while I have configured it (both the DECT registration and SIP to Asterisk configuration), I am running into a "Call missing Call ID from" error message. I can call from a DECT handset to an extension, but not the reverse. Not being an expert, it seems to me that Asterisk is looking for a CallerID from the DECT card. I *believe* I've set everything up correctly, but if anyone has installed this solution and has an example sip.conf file I would be most grateful for a copy. Many thanks, George
