When inserting Ringing() before MeetMe()-conference picked up the call, 
everything works like a charm. I guess the PRI needed to see the ringing status 
before the call was answered. This is however never needed when dialing a 
SIP-extension or similar.

I have also an update considering bad PRI b-channel numbering. It seems that 
only my first 15 channels actually work. Then our PBX tells Asterisk it should 
open channel 16, when it according to Asterisk should be 17, since 16 is the 
D-channel. This mismatch then follows all the way up to the last channel. I've 
read some stuff about Q.SIG. And according to that information Q.SIG has the 
posibility to renumber b-channels, but Asterisk doesn't seem to care about 
that. I have connected our PBX to other PBX'es before, so I do know that the 
PRI/Q.SIG actually works with other implementations. For now I have changed 
chan_zap.c so that it loads the channels differently, when it configures the 
prioffset parameter, I just lower it by one, if it's greater than 15. This 
actually solved all my problems, and now both incoming and outgoing calls works 
just fine.

I know this is not a good solutions in the long run, but it will have to do for 
the time being :)

Ämne: Updated: No audio when dialing in via PRI with Q.SIG

After lots of testing I discovered that I could get the sound to work. The only 
thing I had been testing was MeetMe and Voicemail. But when I dialed a 
SIP-phone, or routed back to other phones via the PRI interface, everything 
works just great! The problem only seem to occur when dialing directly into 
Asterisk, when Asterisk sends the audio output. I have also discovered that the 
PRI never seem to get the signal that the call has been connected when dialing 
into MeetMe, it thinks it's still in the ringing state - I've discovered this 
by watching TAPI events showing up on my other PBX. Is this some kinf of known 
bug in Asterisk? I guess it's because of this I won't get any sound on these 
calls.... When dialing to a SIP phone I get all information.

If anyone have any idea, I'd appreciate it. If it helps I could also send some 
debug logs from ISDN.

Best regards,
