The basic answer is that SIP is based upon HTTP (rfc2068 and rfc2616)
which is similarly defined.
I'm currently not sure of benefi
Hello Guys,
I am having one simple query regarding SIP. May be i'm asking something
silly but please let me know your views in this regards.
Why the "SIP/2.0" is present both in request URI and VIA header? Is it not a
duplication?
Or there is some specific porpose of having in two places.

The proxy in this case is the sipXecs proxy, which sometimes spirals

It doesn't matter. The proxy can explain it in a variety of ways.
*Conceptually* this has passed through multiple proxies that happen to
share the same address and port. It is not for somebody else to judge
whether those are really separate proxies or part of a single proxy.
Note that this isn't
I think Padmaja's hinting that the proxy has inserted those 3 Vias the first
time itself, before it could spiral it 'out' and receiving it back.
If the proxy had spiralled it out, there would be other proxies's Vias as well.
Care to clear this Padmaja?

Hi All,
I'm developing an application (SIP Gateway - 8 channel) to run in an ARM
platform using embedded linux.
I am considering using OSIP to develop my application.
I wonder if it is a good option for embedded systems (low memory, CPU with
low power processing)
and if someone already used th

Hi,
Thanks for the reply. I, however, use only one proxy and that single proxy
has inserted 3 via headers of its own. Please see the Invite from the UA and
the corresponding Invite forwarded by the proxy below. My question again is-
Is it OK to have more than one Via headers inserted by a single p
Yes it is correct to have multiple Vias in a SIP Request. It indicates
how many proxies the request has gone thru before reaching the final
destination.
Actually as per RFC 3261, every proxy adds a Via header inserting its
own address before forwarding the request further. This is explained in
se
Hi all,
Is it OK if the proxy forwards the received invite with multiple via headers
of its own inserted?
For example:
The received invite is this:
