I have the following setup, both routers are Cisco 2811, I am trying to simulate PSTN on one routerB running CME and routerA is an MGCP GW controller by CUCM5. When placing a call from RouterA to RouterB the call goes through fine but when a call is placed from Router B to routerA the call doesn't go through, basically as soon as I dial the number the phone hangs up. I have done debug isdn q931 and getting the disconnect message not sure why.
RouterA ===== Fractional PRI ====RouterB "PSTN SIMULATOR"
*Aug 28 12:46:41.830: ISDN Se0/1/0:15 Q931: Applying typeplan for sw-type 0x12 is 0x0 0x1, Calling num 14085556666
*Aug 28 12:46:41.834: ISDN Se0/1/0:15 Q931: Applying typeplan for sw-type 0x12 is 0x0 0x1, Called num 4085551001
Please ignore the translation and I have removed it, the correct digits forwarded is taken care of by the forward-digits 10 which I have changed it to 11 to send the full number 140855501001. But the call still doesn't go through.
I don't remember what it is but there is something specific when the phone hangs up the call as soon as a number is dialed.
