I have read several posts on this and tried several approaches but can not seem to get it to work. As it stands I am trying to add a=record:on | a=record:off | a=record:pause In the SDP because FreeSWITCH creating the INVITE isn’t able to do this in the way
required. When it is sent from FreeSWITCH a=record:on is send a=record <br>
<br>
I have looked at SDPOPS, TEXTOPS and a few others but non of the offer the option to just inject and a= into the SDP body.<br>
<br>
So as a result I tried a couple of options where the INVITE is created with a=record (unsure why FreeSWITCH wont let us just add :off etc to the end but that’s another point that if anyone know would be helpful) and then using replace_body or search_append_body
but the result is TEXTOPS is unable to action the request because of a SDP parse error<br>
<br>

<br>
Does anyone have any thoughts or tricks on this to give me a few options at ways to handle this?</span><o:p></o:p></p>
