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

[Jason Aarons (US)]

Provider is only sending 300, do you have a match in CallManager? For a
test put a Line X on phone with 300 in none partition.

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 get this when i call 268 87300 , but if i call 268 87324 i get this as
324. As if provider sending only 3 digits??)

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
