<tt>Hi Ryan,<br>
<br>
yeah, this happens because OpenSIPS applies all the changes at the
end, when the message is about to be sent out. As a side effect,
when sending the SDP to rtpengine, opensips does not see its own
previous changes over the body (changes are still pending).<br>
Usually there are easy workarounds for this, but in this case it
looks like bug to me. Could you please open a bug report the the
github tracker.<br>
<br>
Best regards,<br>

<p class="MsoNormal">First some background I’m trying to use
opensips as a webrtc proxy. I found out that the packets for
the invite going to my sip server are too big for my sip
server. It doesn’t like packets to be over 4000 bytes. I’m
trying to take what I can out of the sip packets like codes I
know the other side can’t do. First codec stripping works but
only with the audio codecs. If I try to strip a video codec
the packet gets mangled. This is probably a bug in rtpengine
and not opensips. I was hoping if anyone has any idea how I
might get my invite packets smaller? The webrtc side is
generating ssrc lines in my sdp. I’m trying to strip them out
but I’m not sure if rtpengine is putting them back in or not.
Before my rtpengine_offer I do a
replace_body_all(“a=ssrc.*\r\n,” “”) but the invite still has
all the ssrc lines in it.<o:p></o:p></p>
