oneway voice on 7905G to IOS-Voice-Gateway call

Hi all,

i'm using the H.323-Image on the 7905G-Ethernet-Phone. Call's 7905G-to-7905G work fine, but when I try to place a call toward a legacy phone connected to a FXS-Interface on my 3640-Router, only oneway speech is transferred :-(

The Problem is the direction 7905G --> 3640-Voice

I tried the codecs g729 and g711alaw ans ulaw...

Does anybody have an idea?

Thanks,

//Ronald

I had similar problem with one way audio with GW - GK - GW configuration. IOS upgrade on gateways helped.

Hope it helps,

Re: oneway voice on 7905G to IOS-Voice-Gateway call

i think an upgrade is not possible today...

i'm using 12.2(15)T... I tried 12.2(13)T, (11)T and 12.2(8)T, wich is the oldes-image containing all needed features...

I'be been debugging the RTP-Streams, the Phone seems to be on VAD - but the micro works fine since 7905G-to-7905G calls are possible!

I tried all supported Codecs, too - no way...

any other idea? Regards,

//Ronald
