[Asterisk-Users] h323 with innovaphone ip 400 gatekeeper/innovaphone Ip200 phones

[Martin Bene]

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
