Caller-id Problem in ISDN with CME 4.1

Unanswered Question
Jun 3rd, 2008

Dear all,

I am using CME 4.1 with ISDN PRI. I have got two DID ranges which is mapped to my Ephone's.

dialplan-pattern 1 677011.. extension-length 3

dialplan-pattern 2 677013.. extension-length 3

When user from extension 1.. calls outside then no problem at all.Caller id displays their DID number exactly as 67701174(Eg: if the call made from 174 extension).

When user from Extension 330 - 339 dials out, then the caller id displays as the mainnumber. The reason for displaying main number is if the calling number is different from the DID range allotted then Telco switch will send the main ISDN number.

I tried debugging isdn q931 and found only calls going out from extension 330-339 show as 677067701334(Eg: If i call from extension 334). You can see there is additional digit of 6770 in front of the DID number.

There is no destination pattern clash with any dial-peer also.

Please find attached debug ccapi inout for your reference.

Kindly help..



I have this problem too.

Hi, apparently multiple "dialplan-pattern' have problems, something similar happened to me when I tried, so it can be a bug.

Just use translation-profile and rules at voice-port level and make the changes in there.

Hope this helps, please rate post if it does!

The problem is solved. There was a voice translation ur for /133/ /67701333/

this was actually making the calling number as 677067701334.. When i removed the rule it worked fine.

Thanks for ur support.
