Problems incoming calls

Hi,

We are having problems with incoming calls, when someone makes a call from the outside he can hear the tones but it doesn´t reach the internal phone. I have made a debug isdn q931 and it shows some errors that I don´t understand,

        Bearer Capability i = 0x8090A2

Problems incoming calls

Hi,

Yor call is being received on the router but seems to be getting returned to the ISDN service CO.

Not sure about this original called number

Called Party Number i = 0xA1, '9xxxxxxxxx'

May be you could show the config of the router.

Regards

Alex

Hi,

Can you please attache a CUCM detailed trace, the complete ISDN debug and the router config, also please attach a deb voice ccapi output.

seems that you are getting this from the TELCO

Called Party Number i = 0xA1, '9xxxxxxxxx'

and that is causing the following:

Cause i = 0x8181 - Unallocated/unassigned number

Cause i = 0x809C - Invalid number format (incomplete number)

Seems that this is a TELCO issue, but the traces will give us more info.

This looks to be a dialplan problem.  Make sure that the you are hitting the dialpeers you are expecting to hit.

debug voice ccapi inout

debug isdn q931

Along with a config.

My guess is that you aren't matching dialpeers.

On the outbound call, you have the ISDN plan and type set to national, which means that you need to be careful on the digits that are sent based on the country you are in.

Hi

It looks like a a dial plan or permision problem.

Cause i = 0x8181 - Unallocated/unassigned number

Make sure that the CSS of the gateway and the PT of the final Phone are correct.
