Thanks for replying.

Michael, Is there any plan to add such feature into FreeSWITCH?

It will be very useful for mobile app, because usually mobile (iOS) app can't keep registration alive all the time.
Intercepting call could solve my problem, but not as straight forward as this way.

How can I fork a call to a new registered endpoint?

Here is the scenario:
Callee has 2 devices: dev1 online (registered), dev2 offline

1. An incoming call to the user, dev1 is ringing
2. dev2 register now
3. fork call to dev2

Call flow as below (https://gist.github.com/dylin/5ef157f2bc4da8b1c0b145c03e9efcfd):

  Caller    |     FS      |    dev1     |   dev2
-----------   -----------   -----------   -----------
     |  INVITE     |            |            |
     |------------>|            |            |
     |             |            |            |
     |             | INVITE     |            |
     |             |----------->|            |
     |             |            |            |
     |             |            | REGISTER   |
     |             |<-----------+------------|
     |             |            |            |
     |             | INVITE     |            |
     |             |------------+----------->|
     |             |            |            |

I tried freeswitch.Session("sofia/to/dev2", lega) to originate call to dev2,
and dev2 got call. However if dev1 answered call, it won't cancel INVITE
to dev2 as a normal fork.


Any suggestions are welcome.
