Hi
I read the draft for locating SIP servers using SRV and
there is a section
on how to retry in the event of failure. The only thing
mentioned there is
if the client gets a 503 or there are transport level
timeouts. Now is that
the only implementation? Can the client implement retries
based on certain
4xx or 5xx responses? I was testing a case where I was
sending 500 and the
client wont retry but for 503 it would. So is this really
the final
implementation or its really client specific.
Thanks
Manpreet

To handle a transfer in our network we usually see an
re-invite..

Best place to start would be the following draft that lists

xt
Then refer the RFC 3515 (REFER method)

Ok, so any 5xx, the client should try right? It simply said
503 so I was
wondering. Also the retry mechanism using SXRV for SIP thing
is really
handled at the stack level and not the application level
right?

This draft is RFC 3263.
Also I think the client would try other hosts for error
responses unless
error response indicates a global failure, like 6XX.

Hey Dan,
We've been trying to get transfer working over SIP. We are
using
Bandwidth.com as our provider which in turn uses level3 for
their
infrastructure. Do you happen to have any documentation on
how the
transfer request should be sent? We are trying this transfer
using VXML
constructs and none of the approaches (using
consult/blind/bridge) seem
to work.
thanks
Srinivas
