Hi Anthony,

Thank you very much for your answer.

We have done multiple tests before publishing the question with both READ_ONLY and WRITE_ONLY options.

I think that the basic missing information is how to use the record_session command in the context of the relevant call leg - in all the use cases we tried , the record_session always referred to the first caller (leg a) as the media direction reference point (in the write channel we only saw the audio originated from leg a - without any played prompts - where in the read channel we see the audio originated from leg b + the played prompts).

What we would like to achieve is recording only the write channel for both call legs - the first record_session command (referring to leg a) is currently placed in a dial plan just before the bridge command :

    <action application="set" data="ignore_early_media=true"/>

    <action application="set" data="media_bug_answer_req=true"/>

    <action application="set" data="enable_file_write_buffering=false"/>

    <action application="set" data="RECORD_WRITE_ONLY=true"/>

    <action application="set" data="RECORD_MIN_SEC=1"/>

    <action application="record_session" data="${recordFileName}"/>

    <action application="bridge" data="sofia/gateway/XXX/${destination_number}"/>

I think that the real question is where should we call the second record_session so it will refer leg b?

Again , many thanks for your attention,

Doron.

RECORD_WRITE_ONLY=true should do that.

Hello,

I am trying to perform a record of all legs in a bridge call(and maybe in the future conference of n users) .

It is important to keep the audio quality of the audio  as  good as possible (8khz for non HD and 16 khz for HD).

To be more precise , I am interesting in recording only the WRITE channel of each leg (the READ channel is not important for my purposes).

Currently, the only solution I was able to find was using record_session with STEREO option on the incoming UUID . 

Although I got the bleg audio available on the read channel , I also got all the audio I played to the bridge call on the same channel.

The best solution will be to perform a record for each call leg which will record only the WRITE channel (based on the terminology defined in the record_session API)  - is there currently any way to achieve that?

Best regards,

Doron.
