hey,
i'm new into to list, so don't be too rude with the rookie :)

Here's my question.

We're about to implement SIP 302 into our stack.
By looking at the RFC 3665 ( https://tools.ietf.org/html/rfc3665#section-3.6
), I see a re-INVITE goes to proxy P3 (F4 in the flow) with the same CallID.

Due to some limitations from our side, we plan to do an INVITE (vs a
re-INVITE), by using a NEW Call-ID to P3.
So that will be 2 totally separated calls. First call will get the 302
(which is a final response) and then we'll send a new totally separated
call to the Contact received in the 302 response from call #1.

Do you see any problem(s) by such an implementation?
Do you think that could affect any future transfers (SIP 300, 305) by using
that way?
I know it will have an impact on CDRs, but we have a different approch to
"link" the call together.

Any broken rules that will need us to change everything when implementing a
recent RFC?

Thanks.
Sheldon, the rookie.
