Threading troubles 1.4.5 & IAX2-> SIP

Hi there,

 FreeBSD 6.2
 Asterisk 1.4.5 (and 1.4.3 from ports)

Sip phone - PBX(*) -IAX2-VROUTER(*)- SIP-Voip provider
(SPA901 & SPA922 phones)

We've see a situation where the IAX2 appears to
"loose"/drop the voice
data to be sent to the
SIP side of things. This happens "semi"
intermittently, but we can
reliably regenerate it
at >40 alaw calls (even on a dedicated 1G network) and
also with G729
(but a tad more calls).
It appears to happen using both trunking and non-trunking
modes.

 This happened with DONT_OPTIMIZE setting on or off, but
with it ON it
doesn;t dump core.
At least when it was dumping core, it appeared to have been
in the
pthread_cancel
calls.

We've recompiled the PBX asterisk with no threading, and
the
milliwat/etc. tests to the vrouter
from the SIP phones ran clean (other than when we pushed the
bandwidth
limits <grin>)

 This morning it was consistently the agent (on the SIP
Phones) who
could hear the remote side complaining that the remote side
can't hear
them anymore. After we've recompiled the VROUTER Asterisk
with
non-threading, the calls stayed stable.

 What appears to happen is that somewhere in the threading
the IAX
voice data is discarded or something on the way to the SIP
side.

 Anybody else anything like this?
Any other work around for this issue/problem??

currently 1.4.5 on bsd has issues.

1 because zaptel is out of sync asterisk does not see and
include zaptel in 
its build. 1.4.5 seems to have the iax issue. Asterisk 1.4.6
should be 
released soon to fix the current issues.

I have svn of branches/1.4 and the sip and iax issues are
not there but the 
zaptel issue still is. 

I have worked with killfill from the asterisk-bsd group to
get the ports 
updated but we are waitng to hear back from Gonzo about
zaptel..

asterisk addons also fails to build currently. we are
working to fix this and 
get the ports updated give us a fe more days.
