[SIPForum-discussion] Passing several 2xx responses to server transaction

[Yevgen Krapiva]

Hi.

I need clarification on the following quote from RFC 3261, Response
processing in statefull proxies:

>Step 5. Check response for forwarding
>...
>This step, combined with the next, ensures that a stateful
>proxy will forward exactly one final response to a non-INVITE
>request, and either exactly one non-2xx response or one or more
>2xx responses to an INVITE request.

How can I pass several responses over single server transaction ?
If I pass only one then transaction state will be changed to terminated.
