asterisk users - Jun 2004 - chan_oh323: busy not correctly signalled

Hi,

I have asterisk connected to PSTN via H.323 gateway via chan_oh323.
Incoming calls to SIP extensions work, but SIP message "486 busy here"
from a
busy extension isn't correctly forwarded to H.323.

As a result, a caller from the H.323 side calling a busy SIP extension gets some
rings and then an irritating timeout with H.323 message 'no user
responding'
instead of 'user busy'.

Asterisk knows the user is busy and jumps to the prio+101 extension. The CDR 
also logs the call as 'busy'.

With Zap ISDN channels the following works nicely:

exten => 12345,1,Dial(SIP/${EXTEN},45,r)
exten => 12345,102,SetVar(PRI_CAUSE=17)
exten => 12345,103,Hangup


Can we do something similar with chan_oh323?

Many thanks,
Jan

Jan,

What version chan_oh323 do you use?

Michael.
