TEHO using Transcoding
In my lab, I am seeing this:
When Site A is call Site B PSTN No, the call is routed through Site B ISDN Line (Tail End Hop Off)
The Codec used is G729r8, shown under the show voice call status and under the IP Phone Call Statistic.
Is there a way to transcode this call, so that from the IP Phone to the GW, it is using G729, but from the Gateway to the ISDN Port, it will use G711?
Reason for doing so:
In Real Life, had some issue using G729 codec with some providers ISDN Trunk, they recommend us to send G711 to them.
