I have connected a GSM Gateway and set it up using Sip trunk by line. I’m able to call out using the lines of the sim cards installed in the GSM Gateway by the extensions existing in the UCM. No issues here. The problem is with in coming calls. When i call in any of the lines of the sim cards installed in the GSM
Gateway, the system directs the call to the IVR Prompt with a Welcome prompt. Then when i try to dial any extension it says “i’m sorry i did not get that, please dial again” it seems the system, in this case the IVR of the UCM doesn’t recognize the command. What can i do?
