Hi,

Quick (and simple) question:

Can someone provide a working RTPengine request, to enable Transcoding?

I know, this is possible, but I thought before looking into deep, how this should be configured for the rtpengine_offer() command, could someone provide an example?

It's pretty straight forward.

Example: A offers some SDP to B.

Let's say you think B probably speaks PCMU, so you want to make sure to offer it, even if A didn't offer it: forward transcoding. Add `transcode-PCMU`.

Let's say you also know B is allergic to PCMA, so you want to remove it from the offer to B, but still be able to speak it to A: backward transcoding. Add `codec-mask-PCMA`.

These two cases are really independent of each other, but can be combined.

Full example with some other options:

rtpengine_offer('ICE=remove rtcp-mux-demux codec-mask-PCMA transcode-PCMU')

Simple!

Cheers
