Hi,

Was trying to call from ekiga client for windows to my own domain. Ekiga
client configure with ekiga account, i am calling to my domain riki.ru
to user andres.moya@.... My SIP proxy receive such INVITE from IP of
ekiga UAC:

OK, ekiga UAC is clever to check riki.ru in DNS and connect directly to
my proxy.

But it use some simplified names for fields of a header:
***************************
v: SIP/2.0/UDP
78.146.165.51:10574;branch=z9hG4bK63888eb7-dfff-1810-8a1b-0013ce9f9d7e;rport.
User-Agent: Ekiga/3.2.6.
f: "Mangust"
<sip:Mangust@...>;tag=5a4b8eb7-dfff-1810-8a19-0013ce9f9d7e.
i: 5a4b8eb7-dfff-1810-8a1a-0013ce9f9d7e@VAIO.
t: <sip:andres.moya@...>.
m: <sip:Mangust@...:10574>.
Allow:
INVITE,ACK,OPTIONS,BYE,CANCEL,SUBSCRIBE,NOTIFY,REFER,MESSAGE,INFO,PING.
c: application/sdp.
l: 1016.
***************************
Can it be fixed some how?

The "short" version of SIP headers perfectly legal and documented in the RFC.
The reason why it uses short headers is related to the fact that you enabled too many codecs. It leads to a long SIP message that
can't be transmitted reliably over UDP, so Ekiga uses the compact form for the headers to circumvent that.
