Re: 7975 can't call PRI PBX , but 7911 work well

rick qian · ‎09-10-2010

Hi,

we have CCM 7.1 and one H323 voice gateway connect to AVAYA BPX with PRI E1.another H323 VG connect to PSTN with PRI E1.

our all ipphone in region A,
PSTN's voice gateway in region B
AVAYA's voice gateway in region C.

codec design as next:
G.711: A<-->A,A<-->B,B<-->B,C<-->C
G.729: A<-->c,B<-->C

it works well when 7911 call to AVAYA BPX and all ipphone call to PSTN.
But 7975 call to AVAYA BPX, the Call immediately disconnect after avaya's phone one ring,I can not know what's current codec on 7975.

next I take a call from 7975 to 7911, it's ok,and the call status of 7975 display current codec is g.711,then I use 7911 transfer the call to AVAYA BPX,7975 call to AVAYA PBX successfully ,now the call status of 7975 change to g.729.

show call histroy voice with a successful call from 7911(DN:1002) to AVAYA(DN:117000) at next :

I checked the error code :

DisconnectCause=2F
DisconnectText=no resource (47)

Maybe it means DSP resource lack,but the AVAYA VG has enough DSP resource.

l have a suspicion that 7975 sent some special message to AVAYA PBX,but the PBX can not recognise or accepte .

Any help would be appreciated.

Thanks

Hello Rick,

I had similar problem when my ATA 186 could not call to Avaya (one ring on avaya phone, and that is all), and other phones did. I also had capture in wireshark with code "no resource available".

Problem was slolved by changing the codec on ATA to g729 despite the settings on Avaya was the G711.

I'm guessing that both 7911 and 7975 are in same device pool and had same CSS and partitions apllied to phone and lines.

Maybe you can try to look at the stream on the web page of the 7975 phone when the phone is transfered and connected to the avaya gw, and see what IP address is remote IP address - maybe it is dsp resource address on voice gateways, and because that the call is posible in that case.

Maybe 7975 is trying to use some defferent flavour of g729 codec, where the 7911 uses g729br8.

Can you enable and collect the following debugs for a failed call on the gateway.

debug voip ccapi inout

debug h245 asn1

debug h225 q931

debug h225 asn1

Please note the calling and called party numbers.

Also, include the running configuration of the gateway.
