Incoming Call Dropped Cisco CCME

Hello,

We have deployed a Cisco TOIP Solution for our customers based Cisco Call Manager Express.
The détails of the implementation is below:
- ISR Platform: Cisco C3925
- CCME Version: 9.0 
- IOS Version: IOS 15.2(2)T
- PSTN Access: E1 using primary-net5 as isdn switch type

We have an issue with incoming call: when dialing the DID number of the phone, it rings
correctly but when we pick up the phone, the call is dropped automaticly.

Here is the show of the output of ISDN Q931 debug:

Jul 27 10:13:36.138: ISDN Se0/0/0:15 Q931: RX <- SETUP pd = 8  callref = 0x0033

        Cause i = 0x8090 - Normal call clearing

Thanks in advance.

Looks like it may be a codec negotiation issue.  Can you post your config?

Hi Meade,

Thanks for your reply.

here is the configuration of the CCME.

Thanks in advance.

Hi,

Try and configure the ff on your voice port

voice-port 0/0/0:15

bearer-cap speech

Do a test call and send the debug isdn q931 again.

Hello

Thanks for your reply, but the issue is not resolved and I have the same error on the Debug ISDN output

Have anathor solution

Hello Nizar,

From the isdn debug I see the following:

Called Party Number i = 0x80, '1029'
                Plan:Unknown, Type:Unknown

In the configuration under the dial-peer respective
translation profile iI see the following :

voice translation-rule 3

rule 1 /^/ /0/

!

voice translation-rule 4

rule 1 /7\(...\)/ /3\1/

rule 2 /8\(...\)/ /4\1/

voice translation-profile INCOMING_PSTN

translate calling 3

translate called 4

dial-peer voice 200 pots

translation-profile incoming INCOMING_PSTN

incoming called-number .T

direct-inward-dial

port 0/0/0:15

!

dial-peer voice 201 pots

translation-profile incoming INCOMING_PSTN

incoming called-number .T

direct-inward-dial
port 0/0/1:15


The incoming called number is - 1029 it could not be matched with the rule

voice translation-rule 4

rule 1 /7\(...\)/ /3\1/

rule 2 /8\(...\)/ /4\1/


maybe you need to add:
rule 4 /1\(...\)/ /4\1/

or whatever 1... number should match

HTH,
Alex
