[Freeswitch-users] SIP Call transfer- how to

[Dmitry Mordovin]

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
