Hi all,

I have just try SIP phone on N810. After setting of SIP. to connect to my SIP Server. I got an exeption on My SIP server when parsing Via header.
Then, I have checked SIP message that sent from SIP phone N810 to my SIP Server. Eventuallly, I saw a SIP message as below:

There are no Via header on SIP message and it is "v" instead. So my SIP server can not well parse SIP message.

OPTIONS sip:minhn@157.159.228.8 SIP/2.0
v:SIP/2.0/UDP 157.159.160.166:49167;rport;branch=z9hG4bKHQN1KSmy aFtmQ
f:<sip:minhn@157.159.228.8>;tag=aFr2K3cm5maga
t:<sip:minhn@157.159.228.8>
i:Y-2lQDNexx1Pz00d2MKmpK
CSeq:77822265 OPTIONS
Accept:application/vnd.nokia-register-usage
s:REGISTRATION PROBE
l:0

Any one have the same problem and what should i do . i do not want to modify SIP server because it worked well with most of SIP client exept SIP phone on N810.

Many Thanks in Advance,
-Minh
