CALLS WITHOUT AUDIO

Unanswered Question
Jul 9th, 2010

Hi,

We have a problem in some telephone calls. The problem happens when we make some external phone calls, there isn´t audio and there isn´t tone.

The Gateway is an Cisco 2821.

I have captured a trace of a phone call with the problem:

Jul  7 11:58:24.757: ISDN Se0/0/1:15 Q931: TX -> SETUP pd = 8  callref = 0x2040
        Bearer Capability i = 0x8090A3
                Standard = CCITT
                Transfer Capability = Speech 
                Transfer Mode = Circuit
                Transfer Rate = 64 kbit/s
        Channel ID i = 0xA9839E
                Exclusive, Channel 30
        Calling Party Number i = 0x0081, '926248391'
                Plan:Unknown, Type:Unknown
        Called Party Number i = 0x80, '926410266'
