[Freeswitch-users] Freeswitch with TLS

Dear Sir, I'm planning to use Freeswitch server as a proxy server before OpenSIPS...The Job of freeswitch is only when I need to use SIP over TLS or SRTP when there is a severe firewall on user side...The Client will send SIP over TLS to freeswitch and the freeswitch will forward these packets to openSIPS or kamailio or whatever Registrar server... Is that possible? How many concurrent TLS connection a freeswitch server can handle? Regards
