Hi,
Keep alive mechanisms are described in RFC 4028. If a session refresh is not
received before the interval passes then the UA not acting as a refresher
sends BYE request to termination the session. Is it allowed and possible to
use the Reason header (RFC 3326) in BYE to tell the reason for the
RRC4245 -- sidebars
Hi,
There are requirements related to sidebars in RFC 4245. Some requirements
are related to manage sidebars by sip means. For instance Req 3
REQ-3: A conference participant creates a side-bar conference with one
or more participants in a conference by SIP means.

Hi Paul,
If you are not aware this draft please take a look. I found it very useful

Hi,
Attilas response is correct if a proxy receives an INVITE with out
Max-Forwards header field. I think Navneet is saying "Endpoint"
Section 16.6 point 3 of RFC 3261 says
"If the copy does not contain a Max-Forwards header field, the proxy MUST
add one with a field value, which SHOULD be 70"

Hi Karthik,
As you stated below the B2BUA role is mainly for any kind of services. It
could be PBX, Annoucement, conferencing or for security.
In general SIP proxy provides the routing of sip messages. B2BUA is a kind
of functionality and if you like you can implement together in the same

Hi,
The following para in "13.3.1.4 The INVITE is Accepted" in RFC 3261 is
confusing with the description in 13.2.1 (At the end after the bullets)
I just split the para in 13.1.4 in to two different statements.

Hi,
I have a question related to the usage of Call-Id and CSeq header fields.
I take the examples in section 2 of RFC 3665 (
http://tools.ietf.org/html/rfc3665) and I consider the examples as a
sequence of messages exchanged by a UE. So different messages in section 2.1
through 2.4 are exchanged
