Delay in CME call through BRI ISDN

Hello,

I am working on a issue for a customer where when a caller makes an outbound call, there is a delay of 8-10seconds before the caller hears rinback tone. I have made interdigit timeout to 2 but still the same issue. Are there any settings which can reduce this time?

Some details:

Please provide some debugging information for ISDN by turning the "debug isdn q931" on the CME.

Hello,

You need to ajust the pattern digit length for each dial-peer posts for outbound calls.

regards

Hi,

I the UK we have a variable length numbering scheme.

You weill need to write your dial peers for out going
calls to match at least the most common tye patterns or
rely on the T302 timer

Something like this :-
