Hi Mike, thx. Today we had some failing test fax sessions (g711/PCMA) and my first thought was that it could be caused by FS during transcoding. So I looked into FS logfile and found those hints about transcoding. But ringback shouldn't be the problem.
Fax path was from FAX device (source) through a voip cpe, through a SBC through a SS7 PSTN device into PSTN. Then from PSTN through AVAYA PBX trough sangoma A104d into freeswitch. From there RTP goes to a Cisco ATA to be converted to TDM and consumed by a FAX device (Target). So we have a lot of points to look at ... regrads Helmut > Your playing a tone, we need to encode that tone into the codec of the > channel.
