[cisco-voip] i get busy error w/ isdn incoming calls.

[Aykut NURAT]

Hi Everyone,

I have a problem with an mgcp gateway.

I can call from internal ip phones to pstn numbers without a problem. Hence my mgcp gw is up&running and registered to my CCM 6.1. I have an ISDN PRI e1 and it is also up and there is no problem w/ outgoing calls as mentioned before.

But i have problems w/ incoming calls from pstn to internal phones.

 

Because this is an urgent situtaion just wanted take your opinions before making a widened search.

 

Here is isdn q921 and q931 output.

When i call from outside pstn to internal numbers i get the below output:

I have tried many pri settings on my CCM. I tried decreasing significant digits coming from pri to 4 and wrote translation patterns to internal numbers but no way.

 

 

Any comments and suggestions will be highly appreciated. 

 

Best,

Aykut
