[Asterisk-Users] ISDN PRI No Audio

[Andy Brezinsky]

Our setup:

We have a DS3 from Global Crossing terminating into a Adtran MX2800 M13 
mux.  From there, groups of 4 T1's run into T410P digium cards to 7 
individual servers.  Each trunk is configured as ISDN PRI, B8ZS/ESF, 
D-channel being chan 96 with B-channels of 1-95 (we're using NFAS).  The 
D channel is up and there are no alarms.  We see the connection on the 
console from the incoming user as seen below, if the user hangs up it 
disconnects properly, we can also do a zap destroy and disconnect the 
user.  It seems that bi-directional communication is alright.  We were 
running 1.0.7 but upgraded to CVSHEAD to see if a fix existed.

Console Output:
    -- Accepting call from '414944XXXX' to '80094042XX' on channel 2/24, 
span 4
    -- Executing Wait("Zap/48-1", "3") in new stack
    -- Executing Answer("Zap/48-1", "") in new stack
    -- Executing Playback("Zap/48-1", "tt-monkeys") in new stack
    -- Playing 'tt-monkeys' (language 'en')
    -- Executing Read("Zap/48-1", "TEST||2") in new stack
    -- Accepting a maximum of 2 digits.
    -- User entered nothing.
    -- Executing SayDigits("Zap/48-1", "1111") in new stack
    -- Playing 'digits/1' (language 'en')
    -- Playing 'digits/1' (language 'en')
    -- Playing 'digits/1' (language 'en')
    -- Playing 'digits/1' (language 'en')
    -- Executing Hangup("Zap/48-1", "") in new stack
  == Spawn extension (default, 80094042XX, 6) exited non-zero on 'Zap/48-1'
    -- Hungup 'Zap/48-1'

The Problem:
No audio and no DTMF tones are passed.  We cannot hear the test audio, 
we cannot send digits back and we cannot hear the digits being said.  
GBLX setup a tap and said we were not sending them any audio at all so 
we're fairly certain this problem is on our end and not theirs. 

We're at a loss here and can't really figure out what's wrong.  Can 
someone provide some insight into this problem?

Thanks
