[Asterisk-Users] Codec format conversion error

[Apu Islam]

I am spinning with this for a while. This is a new server that I built
with AAH 1.3 with oh323 support. When I call other parties with my IP
phone, I can talk just fine however I am not hearing anything from
astersik. I ran the server in debug and noticed this :

Aug  6 17:04:43 DEBUG[1429]: Set channel SIP/204-04fb to write format slin
Aug  6 17:04:43 DEBUG[1429]: Ooh, format changed from unknown to ulaw
Aug  6 17:04:43 DEBUG[1429]: Scheduling timer at 160 sample intervals
Aug  6 17:04:47 DEBUG[1429]: Got RTCP report of 84 bytes


my IP phone is set up to send alaw. I can talk to other extensions
just fine but astersik audio I cannot hear.
Also, I have only alaw and ulaw allowed on my sip.conf however when I
check show codecs, I get this :
        INT    BINARY        HEX   TYPE    NAME   DESC

is my codec order messed up ? how do I change codec order ? sip.conf
didn't do it for me.
any suggestion would be appreciated.
