How to configure sending DTMF codes for a long distance provider via ISDN?

Hello!

I've cisco 3825. I want to configure sending DTMF codes after call setup to long distance provider.

I solve this in fxo by dial-peer configuration:

dial-peer voice 107 pots

trunkgroup common

permission term

description From Common - test

huntstop

destination-pattern 11005318751

prefix 11005318751,,,,,,,,,,42641980255

But this configuration doesn't work for isdn.

I think only tcl can solve my problem. I'm right?

Re: How to configure sending DTMF codes for a long distance prov

ISDN doesn't use DTMF for call setup which is why the configuration you have used for POTS doesn't work. The gateway collects all digits and send it out in a H.225 setup message, rather than playing it out over the voice channel.

As for how to do that... There maybe an option using a custom made TCL script/application, but it would definitely be a solution that was outside the box. I'm afraid I don't know TCL well enough be help you out there.
