System prompts the calling conference site number is too long.

Handling Process

Checking area code set, and we find our system has every capital cities area codes and municipals area codes but no non capital cities area codes. So add the calling PSTN terminal area code to area code set, then conference calls PSTN terminal successful.

The terminal operation and PSTN number have no problem. The problem occurs in platform according prompt. Calling the PSTN phones from other capital cities has no problem, which means the basic PSTN setting is good.


Suggest adding all cities area codes in province platform.
