<div dir="ltr">Hi Anthony,<div><br></div><div>Thank you for your answer - </div><div>Your advise do works when we try to perform a single record_session call per bridge call - but when we are trying to perform 2 calls , in order to get each channel in a different record file, containing only the audio originating from each side, we get 2 identical records.</div>
<div>It seems like the record_session is using a global context, and the second call overrides the first call settings - is my observation right? - is it part of the design to perform multiple records per session?</div><div>

<div>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).</div>
<div>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 :</div><div>
<br></div><div><div> <action application="set" data="ignore_early_media=true"/></div><div> <action application="set" data="media_bug_answer_req=true"/></div><div>
<action application="set" data="enable_file_write_buffering=false"/></div>
<div> <action application="set" data="RECORD_WRITE_ONLY=true"/></div><div> <action application="set" data="RECORD_MIN_SEC=1"/></div><div> <action application="record_session" data="${recordFileName}"/></div>
<div> <action application="bridge" data="sofia/gateway/XXX/${destination_number}"/></div></div><div><br></div><div>I think that the real question is where should we call the second record_session so it will refer leg b?</div>
<div><br></div><div>Again , many thanks for your attention,</div><div><br></div><div>Doron.</div></div><div><div><div class="gmail_extra"><br><br><div class="gmail_quote">On Wed, Jul 24, 2013 at 1:41 AM, Anthony Minessale <span dir="ltr"><<a href="mailto:anthony.minessale@gmail.com" target="_blank">anthony.minessale@gmail.com</a>></span> wrote:<br>
