Actually - I think I figured it out - using opus if I sent  this: 

"a=rtpmap:111 opus/48000/2

a=fmtp:111 minptime=10; useinbandfec=1; stereo=1; sprop-stereo=1"

that would mean "using the opus codec, min packet time 10, forward error correction on, stereo receive on,  stereo send on"

so, if I set sprop-stereo=0 or omit it entirely, it should mean rcv stereo send mono, I think. Agree?

Is that something you set up in the local sdp (all guidance appreciated)

Can you have an endpoint that is mono transmit and stereo receive in this scenario?

Negotiate a call between a mono and stereo endpoint and it will do this.

Hi,

We need to set up calls in FS where a mono signal coming into Freeswitch is split into a stereo signal.  What is the easiest way to accomplish this?

Thanks
