[Asterisk-Users] sound quality IAX client GSM to ALAW with oh323

[Arne Scheffer]

Hello veryone,

I have a strange problem. I have an asterisk (latest from CVS) with latest oh323 channel driver.
I place calls with DIAX.

The H323 gateways only support G711A
De DIAX only supports GSM

When I perform an inbound call:
H323 -> asterisk -> DIAX  :: sound is ok.

When I perform an outbound call:
DIAX -> Asterisk -> h323 :: sound is terrible and CPU load is 80%

When I perform an asteisk internal call with DIAX:
DIAX -> asterisk IVR :: sound is good and cpu OK.

Does anyone else have this problem ?
Know how to solve it ?

regards,
Arne.
