Hi;
Multi-Homing is used when the Proxy acts as the Proxy Server for
multiple domains from a single
place.
Some times a request arrives from one of the domains managed by this proxy
to another domain managed also by this proxy.
If both domains are configured to RR, the end UA ( the destination )
in a normal situation see the request with 2 RR headers.
If the Multi-homed proxy whants to mimic the default behaviur
it can add two RR and flag them with r2 so it will identify them
on further requests in the Route header and remove them.

Niranjan,
Multi-homing and multi-streaming are generally used when your proxy acts
as a B2BUA. These are used because B2BUA is a single point of failure
and hence High Availability needs to be added for robustness.
My guess is your proxy is acting like a B2BUA. Can you check your proxy
behavior?
Thanks,
Sai.

Subject: [Sip-implementors] Multi homed Proxy
Im working with an implementation of a Multi homed proxy - uses 2
interfaces, I presume one external and one internal.
On receiving a request on one interface, it forwards it to itself on the
destination interface, eventually adding itself twice in the
Record-Route header (with r2 parameter) before forwarding the request.
Response is processed similarly.
Why is such a behaviour required? If this is to seperate the netowrk
topology (external, internal) the same can be achieved by an IP gateway.
I am sure there is only one instance of the Proxy running on the host.
This behaviour is not affecting our functionality. But I need to
understand the reason behind it.
Any pointers appreciated.
Thanks.
