Re: 8941 external call issue

Hi,

I had a similar problem with 8945 phones.

The phone tried to call out by default with bearer capapility video and therefore the calls to some destination where recected.

To solve this problem I did the following change on the voice gateway:

voice-port 0/0/1

bearer-cap speech

8941 external call issue

Hi,

WHats the symptom ? U get fast busy /reorder right away or u hear ringback and call disconnets? Can you use DNA and check quickly, to isolate any config issue ? Use DNA ---Find phones----and then find 8941 and enter the line and enter called party and check if it successful. And check if the call flow /call path for the other phones which are working and 8941 which is not working.

Whats the call flow ?

Re: 8941 external call issue

Did you use DNA ?

Ok, If it is PRI T1 quickly enable debug isdn q931 and see if the call makes it to Telco or even the GW. Enabled respective debugs :-

Along with isdn q931/debug vpm sig(CAS)

h323 (debug h225 asn1 and debug h245 asn1)

SIp:- debug ccsip messages

MGCP:- debug mgcp packets

And send us. Lets see if the call makes it to GW.

THanks,
