[Asterisk-Users] Call dropped 100% of time when incoming IAX routed to outgoing CAPI
Good day,
The unusual thing about this problem is that it doesn't occur just during a
CAPI call, or just during an IAX/SIP call. Only during IAX/CAPI
I'm having some trouble with the CAPI interface and it only occurs when a
call
comes in on an IAX channel and goes out the CAPI interface.
The capi debug in the asterisk console is below as well as the relevent parts
of .conf files from the machines involved.
The scenario is this (extension numbers):
4074 is connected to a Siemens Hipath 3000 PBX.
The Hipath3000 has a cable running to asterisk at address 192.168.1.222
connected to a wcte11xp zaptel card - Single span PRI.
The asterisk at 222 just mentioned (*@222) is on the LAN and it accepts calls
from the Hipath3000 in a certain range and sends the calls to locally
connected SIP extensions. When ext 4074 calls 4050 we've set up a test
scenario where the Hipath3000 sends all calls for 4050 to *@222, which then
has an IAX connection to another asterisk machine set up at 192.168.1.224
(*@224). This call is then sent out the CAPI interface on the second
machine to the Hipath3000 and pointed to extension 4028. This connection
drops out 100% of the time at different times though - none longer than
one minute. On this particular debug within asterisk the call got dropped
during the ringing stage.
4074 dials (4050) hp3k pbx -> in thru zap *@222 -> iax to *@224 -> capi
to
hp3k pbx -> 4028
The CAPI device is an AVM C2 card on the 224 machine
chan_capi version is 0.5.4 on 192.168.1.224
asterisk version on 192.168.1.222 is CVS-HEAD and the chan_iax2.c files says
revision 1.332
asterisk version on 192.168.1.224 is Asterisk 1.0.9

Just to re-iterate, the CAPI interface is fine when it is used as a normal
operation from the extension.conf file,
i.e. exten => 5555,1,Dial(CAPI/g1/${EXTEN}
The problem only occurs when it is an IAX call coming in and being routed out
the CAPI interface.
