No incoming calls in SRST mode

We have the following configuration at a remote site and have issues with incoming calls when in fallback mode, outgoing calling works fine, but incoming gives busy tone.  Can someone see anything wrong with the config?  Thanks.

Hi,

Can u run the cmd:

debug isdn q931

and

debug voice ccapi inout

Make an incoming call and post the debg outputs.

A very similar configuration structure to how I configure SRST.

Try applying your translation profile to the voice port rather than the incoming dial-peer, as that is the only obvious difference I can see.

Cheers,

Alistair

Yeah your missing a translation pattern.  Here's an example for what you need to do for your VGR:


* PSTN sending us the last 4 signifcant digits of our DID.  And we have a phone using DN 2303

voice translation-rule 100
rule 1 /3600/ /2303/

voice translation-profile voice
translate called 100

dial-peer voice 1 pots
translation-profile incoming voice
incoming called-number .
direct-inward-dial
port 0/0/0:23

-rya

Thanks, I 'll try the suggested and get debugs if necessary...Will post back soon.

As ryabutler put in his dialpeer config you should put in the "incoming called number ."  command in dial-peer voice 1 pots. I am guessing that if you run a debug you will see incoming calls matching on dial-peer 1. You could probably just shut down that dial peer then then they will match on dial peer 2 and all should work fine I would guess. But i would add the command that ryabutler told you to add then give it a try.

Here is a doc you can reference for when you are experiencing no imcoming calls when running mgcp with your srst config on isdn or pots lines.
