5. Device pool contains RG-Trunk
------------------------------------------------------
debug isdn q931
debug ccsip messages
Call fails to 911
1.Call is not hitting to pots dial-pear
2. IN ccsip messages i got an error in 5th message
500 internal server error
How i can solve this problem???

[Terry Cheema · Accepted solution]

under your dial-peer 100 and 101, add the command: "incoming called-number ."

You dont have incoming dial-peer for calls coming from CUCM on this trunk.

If still doesnt work, post the output of debug isdn q931 and debug ccsip messages.
