Hello all,

I would like to know if stunnel is able to encrypt a SIP message (UDP or TCP => TLS...)
For example:
Terminal A can send/receive SIP messages on transport layer UDP or TCP but not TLS.
Server B can send/receive SIP messages only in TLS.
If terminal A sends a SIP REGISTER message to Server B, does stunnel is able to intercept the message and transform it ?
port 5060 => port 5061
sip uri => sips uri

Do you think it's possible with stunnel ?

Thank you very much for your input.
