[Asterisk-Users] Bristuff wackyness - not answering

[Clive]

Hi

Is anyone having this weird trouble with bristuff....calls don't get 
answered, but on the debug it looks as if the call is answered. The call 
will just hear ringing.
I am using -BRI-stuffed-0.1.0-RC4a

Occassionally the system starts working on its own, other times I have 
to stop and rmmod everything and start them all up again.

 These error messages appear on the CLI:

== Primary D-Channel on span 2 down
Sep 5 02:13:04 WARNING[213005]: chan_zap.c:1942
pri_find_dchan: No D-channels available! Using Primary on
channel anyway 6!

 WARNING[213005]: chan_zap.c:6902 zt_pri_error: PRI: !! Not good - 
head of queue has not been transmitted yet
WARNING[213005]: chan_zap.c:6902 zt_pri_error: PRI: !! Got reject 
for frame 8, retransmitting frame 8 now, updating n_r!

kernel: zaphfc: empty HDLC frame received.

Any help or pointers will be appreciated.

Thanks and regards
Clive
