Re: [Sip-implementors] Problem with BYE

Yes, you are correct that this is also a problem with the message since the BYE came from the same UA as the INVITE.

Shouldn't the CSeq of BYE be diffrent(greater) than that of INVITE ??

Hi Mariusz,

One thing I see is that your BYE request doesn't contain a 
Max-Forwards 
header, which is required per section 8.1.1 of RFC 3261.

Hello everybody,

I'm writing a SIP User Agent and I have problem with terminating a 
dialog with Ubiquity UA using BYE.

My testing environment consists of my UA and Helmsman User Agent v 
3.0.6 (http://www.ubiquity.net/useragent.php).
The tesing scenario is as follows:
o Helmsman UA starts the dialog (INVITE)
o My UA accepts the dialog (200 OK)
o My UA terminates the dialgo (BYE)
First two steps are done correctly. But as I send the BYE 

request it 

does not receive a final response. The Helmsman UA sends only a 
provisional 100 Trying.
When I use another remote UA (josua -- 
http://www.fsf.org/software/osip/) the BYE gets a positive response 
(200 OK).

Is there something wrong with the following message:

BYE sip:[EMAIL PROTECTED] SIP/2.0
