Hi,
I'm trying to get h323 communication working between asterisk (0.7.1) and
Innovaphone Gatekeeper + innovaphone phones.
chan_323 installed OK with currently recommended pwlib_1.5.2 and
openh323_1.12.2.
Registration asterisk with the gatekeeper works OK, externsion for my
test(sip) phone gets registered with gatekeeper. when establishing a call
between a h323 phone and asterisk I run into problems however (regardless of
direction - doesn't matter who and who answers):
While asterisk can receive audio from the h323 phone quite fine, reverse
doesn't work.
After a few seconds, connection is disconnected with error message: -- Could
not find common codec with 514
>From network dump, I can see that no RTP Data travels from asterisk to the
h323 phone. different allow/disallow settings in h323.conf don't change
things, currently I've got the followin there:
allow=all ; turns on all installed codecs
disallow=g729
disallow=g723.1
;disallow=g723.1 ; Hm... Proprietary, don't use it...
The network trace of asterisk <=> gatekeeper conversation looks reasonable at
first glance - but then I'm not sure what I'm looking for.
altertingOpenLogicalChannel message from gatekeeper specifies g711Ulaw for
both forward and reverse logicalChannel parameters
Anyone got an idea where to start looking for the reason asterisk doesn't
find/use g711Ulaw to communicate with the h323 phone?
Thanks, Martin
