SBC Transcoding and Call Hold
Hi,
I'm trying to configure the SBC to transcode between the ingress side that runs G.711 and the egress side that runs G.729.
I have setup the configuration as described in the book and the call is indeed set-up with transcoding. The problem start when the calling party puts the call on hold. The messages exchange that follows (see following/attached call flow) stops the transcoding and revert the call on both side of the SBC to G711.
How can I force the SBC to keep transcoding all through the call and call hold ?
Thanks
