If iPhone is changed to sleep mode, RealPresence Mobile for Apple ios is to be offline in our gatekeeper.
I found the reason in Polycom community. Is there any solution for this problem?
In RPM for Android, there is a "Keep Alive in Sleep Mode" function!!
But RPM for Apple iOS doesn't have.
Someone advise me to use registration refresh interval in Gatekeeper.
He said that iPhone awakes every 10 min in sleep mode (I can't confirm this), so Gatekeeper refresh interval should be longer than 10 min.
But he warn that it would be possible to have another problem.
Soon Polycom would provide upgrade for this problem.
Thanks for reply~~
iOS will close down all applications after 10 minutes of inactivity. Polycom is investigating options to keep the application 'awake enough' to receive a call from suspend state, but this is not committed on the road map at present.
