[TLS] Question about SIP on TLS

[Nabil.HAMZI at fr.thalesgroup.com]

Hello ! 

here is my goal : 
=> i have some phones as SIP TLS clients
=> and a proxy/registrar as SIP-TLS server

And without TLS everthing working fine :
1) When a client needs to send a message, he opens its session with the
server. OK.
2) When the server needs to send a message he has to open his session with
the registred phone. No problem for TCP layer.

But with TLS :

For the case 2), there is a problem for TLS layer as the Phone (TCP server)
is not a TLS server.

I mean that in order to have it working, do we need to keep a TLS session
always valid ?
