[SR-Users] append new a= in SDP (without rtpengine)

[Lewis Hutchinson]

version: kamailio 5.5.3
Using KEMI Python

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

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.

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

DEBUG: <core> [core/parser/sdp/sdp.c:599]: parse_sdp_session(): ignoring unknown type in a= line: `a=record#015#012a=ptime:20...'

Does anyone have any thoughts or tricks on this to give me a few options at ways to handle this?
