Post by Poonam2 GuptaHi Pranav,
Thanks for quick reply.
I have some more questions now.
It means that in case of Mirror Proxy mode , Endpoint information is not kept at the node.
Second Question: what is the advantage for OBP mode? Can OBP?s URI and
realm address be different?
Third question : how Endpoint gets advantage in OBP mode?
Regards
Poonam

Hi Poonam,
*OBP or Out-Bound Proxy or Access mode* In OBP mode, endpoints are
registered with, and authenticated by, an external registrar server
although your node keeps all the information of registered endpoint.
The SIP registrar server to which S3 will forward REGISTER messages must
be provisioned as an endpoint on your node, including specifying its SIP
URI parameter.You will send these packets to your node's realm's address
but with the out-bound proxy's URI.
Normally, in order to use out-bound proxy (OBP) functionality, an endpoint
must have built-in OBP support. For endpoints that do not support OBP
intrinsically, *mirror proxy* feature comes handy.
Mirror Proxy is when node acts as a proxy for the proxy registrar server.
And in *non-OBP* mode or inter-connect mode your define static endpoints.
You also define call routes and plans.
I guess these features are implemented in a session border controller.

Hi,
Need to know about OBP mode, non-OBP mode and Mirror Proxy mode in SIP.
Basically I wanted to know what all different headers are changed in each kind of proxy?
Regards
Poonam
