Hi,

Everything was running well between SRC, drachtio and rtpengine and can get recording file. But we have question from our observation, we found that drachtio does not send any attribute back when SRC send invite with "sendonly" attribute.

If we manipulated SDP on SRC to send with "sendrecv" attribute, drachtio will send back with same attribute ("sendrecv").

We are still learning about drachtio behavior and as far as we know when SRC send invite with "sendonly" attribute it should get response with "recvonly" attribute?

I have also attached log file from drachtio server. drachtio_siprec.log

we already can get response 'a=recvonly' by add 'a=recvonly\r\n' to this file https://github.com/drachtio/drachtio-siprec-recording-server/blob/main/lib/payload-combiner.js, line 32
