[Serusers] Routing subsequent SIP traffic through the proxy

Hello Jiri,

Of course, I meant the non-paranoic meaning, that is forcing the subsequent
requests to go through the proxy.

The question is related to the FCP module I'm trying to complete. In order to
close the previously opened ports, the module needs to see BYE and CANCEL
messages. When adding record-routing header from a natted proxy, this address
must be changed to a public one whenever the message is for the public Internet.
Is my understanding correct?
My other concern with Record Routing is whether this translation for the request
involves translating the RR field back to the one of the natted proxy, when the
response hits the proxy.

I'm not sure what it means "all SIP messages". In a paranoid understanding, that
would include interception of iptel.org messages by someone else.

In general, there are two options: setting an outbound proxy in phones and
forcing subsequent requests hit a proxy through rr-ing.
