Hi list, I'm using FS with proxy-hold.
Call flow is simple
A -> FreeSWITCH -> B
Assume FS, A and B support PCMA and PCMU, FS prefer PCMA in codec-prefs profile configuration.
In affects of my configuration for
greedy early negotiation and
disable transcoding, PCMA is negotiated in both legs for initial INVITE, that's good, and expected.
But then I remove PCMA from A and compose a re-INVITE for holding with PCMU only, the a leg is re-negotiated with PCMU, but the b leg have re-INVITE with PCMA due to
proxy-hold variable, that causes transcoding happened after hold.
My desire is to have FS to re-negotiate with b leg too, not so similar but as what I observed when I was using it with media proxy option ( A-A before hold, U-U after hold).
