isdn incoming calls fail

Hello all, 

I am dying with this issue from the past one week.

3 different location with 3 routers and 3 pbxs PRI trunking between router and pbx.

Calls from voip to analog works fin

calls from analog to IP or analog to analog fail.

after receiving one digit from isdn, receiving rx <- disconnect msg from pbx.

please find the attached config below.. along with the log

note: in the logs, the last call is from analog to ip which is failed.

IP phone: 501

analog phone: 270 / 140

thank you in advance.

As i can see from logs you


As i can see from logs you are using Overlap digit from PBX and with Overlap receiving the router, it tries to place the call after enough digits have been received to match the destination number. In this case, after the 5 has been received. To prevent this from occurring the "T" terminator should be placed after the digits in the destination pattern. This causes the router to wait for the T302 timer to expire after each digit's reception, allowing the full number to be collected before placing the call.


So please put ammend dial-peer 10 pots which is your Incoming pots dial-peer with T after incoming called-number and it would be:

dial-peer voice 10 pots
description ## Inbound from Iris PBX ##
incoming called-number .T
direct-inward-dial
forward-digits all

Hi maveer,

Hi maveer,

Actually by deleting the direct-inward-dial solved the issue.. 

Now am facing a very annoying issue.

Ip phone registered to cme --> ip phone registered to cucm

configured voip dialpeer in cme 

configured sip trunk in cucm

not able establish the call.

output from the debugs: 

debug ip tcp transactions

debug voice ccapi inout
