Hi, Try Bria's push service. They will keep your registration and wake up your offline phone on call.

Hi,

I am trying using freeswitch as sip servers for mobile client. And I have a question. If we call a group call to freeswitch, say group 100 with user 1001,1002,1003. And at this time, 1001 & 1002 is online but 1003 is not online. I want a behavior that call to group 100, 1001 & 1002 will ring, and after I notify user 1003 registering to freeswitch, 1003 will ring too and can pickup the group call just like 1003 is online while you making the group call.

Is that possible? Or is there any way to achieve it? using call-center?

Many Thanks, Leo _________________________________________________________________________
