I have CCM 7.1.2 & voice gateway with SRST license.
In Voice gateway FXO/Analong lines are being terminated. I also has PRI terminated on the VG.
The problem that i am facing is: whenever i do receive an incoming call it is displayed on the ip phone as "Unknown Number". I have taken CLIP service from the service provide.
Still the problem is happening.
Can someone guide me how to sort out this issue.
Voice gateway is registered with CCM via MGCP.
