Feature Issues
1. Calling Party Number is not displayed on the Caller ID for FXS ports after receiving a call via CM. This
is due to CM not sending the Calling Party Number to the MultiVOIP as part of the Q.931 setup
message.
2. “Unknown Name” is displayed on the Caller ID for FXS ports after receiving a call from a MultiVOIP
FXO port that was routed by CM. This is due to CM sending “Unknown Name” in the Display field of
the Q.931 setup message instead of the actual Caller ID Name received by the MultiVOIP FXO port.
