Can't make calls with video dial-peer

Unanswered Question
Jun 24th, 2008

I want to establish videoconferences using a cisco 7985 against an external system. At first I thought that I had problems with numbers that belonged to video peers, but then I realized that it was the same with normal peers, but always that I used this dial-peer.

The dial-peer that I'm using is:

dial-peer voice 100 pots

destination-pattern 70.%

information-type video

incoming called-number 91732XXXX

bandwidth maximum 128 minimum 128

port 0/0/1:15

forward-digits 9

!

dial-peer voice 101 voip

destination-pattern 70.%

voice-class codec 2

session target ipv4:10.252.a.b

incoming called-number 7091837YYYY

!

When the call is made, it shows this disconnection cause:

Jun 23 18:23:43.539: ISDN Se0/0/1:15 Q931: RX <- DISCONNECT pd = 8 callref = 0x0043

Cause i = 0x80AF - Resource unavailable, unspecified

Display i = 'RECURSOS NO DISPONIBLES'

….

Call Entry(Disconnect Cause=47, Voice Class Cause Code=0, Retry Count=0)

If followed a guide to configure this dial-peer, but obviously I did something wrong. I think it may be related with the primary and secondary channels, but I'm not really sure how to configure them.

Any idea it could work?? I will appreciate any kind of help. I attach the configuration file and a trace file. Thank you very much.

I have this problem too.

i think you have to put the bandiwdith duble

for example u have put it like 128 try to make it 256

also if you have deffrent codec in use check XCODING resources

good luck

for Voice, XCODER resources will not be invoked using voice-class codec X.

Dial-peers must be set hard! (i.e. codec g711ulaw)..

I am working on the same issue and I have upgraded the bandwith to 256 kbps, removed the voice-class codec from the dial-peer and established codec g77ulaw as the unique codec, but it is still not working. Any other idea that we could try??

Thank you very much!!!

Now the dial-peers are this way:

!

dial-peer voice 100 pots

destination-pattern 70.%

information-type video

incoming called-number 917328040

bandwidth maximum 256 minimum 256

port 0/0/1:15

forward-digits 9

!

dial-peer voice 101 voip

destination-pattern 70.%

session target ipv4:10.252.100.11

incoming called-number 70918379060

codec g711ulaw

!
