[Freeswitch-users] Problem with 'sips' prefix

Hi, I'm using FS 1.4.18. I'm using TLS and SRTP. I'm trying to initiate outbound call with destination set to sips:something using "originate {return_ring_ready=true}<destination> &park xml default" command. Checking outgoing trace, I can see that destination in INVITE SIP Request URI becomes sip:something. Is there a way to force or enable 'sips' instead of 'sip'? Regards, Miro
