Hii experts,,

I have an issue with my phone 7980 when I try to make a call throught the PRI it is only ring once then busy tone.

My VGW is 2811 and the PRI configuration as below:

interface Serial0/0/0:15

no ip address

encapsulation hdlc

isdn switch-type primary-net5

isdn incoming-voice voice

isdn bchan-number-order ascending

no cdp enable

voice-port 0/0/0:15

bearer-cap Speech

And I configure a voice calss codec with G711 and g729 codecs and applied it to the Voip dial peer.

PLZ note that the calls therougt VGW 3825 are working fine.
