I'm stumped on a caller ID issue where a new setup is not receiving callerID on the Cisco phones from external PSTN calls through an H.323 VG. When I call from a US cell phone to the VG in China, I get this from the debug:
Apr 22 2010 21:07:43.509 SHG: [0/1/0] get_fxo_caller_id:Caller ID receive failed. parseCallerIDString:no data
The running-config shows this POTs line setup as:
supervisory disconnect dualtone mid-call
timeouts call-disconnect 1
timeouts wait-release 1
My initial thought is the China Telco is not passing CallerID, but the tech on that end double verified with them and unplugged a POTs line from the VG and into a phone and validated that claim. My new thought is possibly having to do with the number of digits as when I call it's 15 digits in length, wheras when the tech calls from his cell phone, it's a more moderate number. Could this be a possibility? Is there another place I should have settings enabled to pass CallerID in the VG or should the lines display what's passed by default?
Thanks in Advance for Assistance!
