Friends, Could someone explain me how this feature works? Using FS default configuration and free sip softphones. Call transfer case - 1001 user call to 1002 and talks - then 1002 user transfer 1001 user to 1003 user - 1002 hang up - 1001 and 1003 continue talks Is it possible? How can do it? Which technology (protocol, messages) using for it? DTMF, FS application, SIP messages or else Thank you! Dmitr
