Hi guys,
I'm working on a simple application using PJSIP. I need to use the
"extension header" of RTP
(http://www.pjsip.org/pjmedia/docs/html/structpjmedia__rtp__ext__hdr.htm).
It seems that it's possible to access the extension header from an incoming
RTP packet (in the decode function pjmedia_rtp_decode_rtp) but I didn't find
a way to include an extension header in a RTP packet that I want to send,
during established session.

Is possible to send an RTP packet with an extension header with PJSIP, and
if not where would be the best place to implement the necessary changes?
There are some high-level functions that implement this feature (for example
in PJSUA)?

Thanks in advance

Best Regards
Ll
