Hello My setup look's like this: [* with oh323 and g.729 codec's] - [dlink dg-104SH, h323 with g729] Dlink configured to send a call to * directly, so when I call 006 it comes to * extension 006. On it I place echo-test. I hear voice greeting and after few seconds asterisk hangup channel with such diagnostic: -- Executing Playback("H323:14525", "demo-echotest") in new stack -- Playing 'demo-echotest' (language 'en') 0:10.641 LogChanRx:8146470 H323RTP Payload size too small, short 6 bytes. -- Executing Echo("H323:14525", "") in new stack == Spawn extension (bond, 006, 2) exited non-zero on 'H323:14525' *** [ip$xx.xx.xx.227:41326/14525] H.323 CONTROL PROTOCOL ERROR (Logical Channel ) -- Hungup 'H323:14525' 0:40.668 LogChanTx:8135760 Codec Audio read failed: 0:40.692 H225 Answer:80e40b8 H225 Read error (0): 0:40.751 H323 Cleaner H323 Connection ip$xx.xx.xx.227:4132 6/14525 terminated. So, what can be a problem ? -- ... All opinions expressed are mine and not those of my employer.
