[Asterisk-Users] IAX2 to IAX2 - one way audio

[Andrew A. Kochetkoff]

Hi, everybody.

I have schema:


           H323(cliens)<---------->GNUGK<--------------
                                                      |
                                                      |
    SIP(cliens)<--->Asterisk(B)<---(IAX2 TRUNK)--->Asterisk(A)<--(H323 Peer)-->PBX<---->PSTN
                                                      |
                                                      |
           SCCP(client)<-------------------------------

ASTERISK(B) - Linux + Asterisk-1.0.6 (IP-addressing INT-192.168.1/24 EXT-62.XXX.XXX.128/25)
ASTERISK(A) - FreeBSD + Asterisk CVS-HEAD-04/14/05-21:00:38, Copyright (C) 1999 - 2005 Digium.
(IP-addressing INT-192.168.100/24 EXT-62.YYY.YYY.192/27)

When I call from PSTN to any clients - call is Ok!
When I call from SCCP to any - call is Ok!
When I call from H323(clients) to any - call is Ok!
When I call from from SIP to PSTN - I have one way audio (PSTN-subscriber can hear SIP-client, at 
the same time SIP-client doesnt hear PSTN-subscriber).
