Need a method to force registered flexisip clients to re-register

[piajesse]

Currently our linphone apps will register through flexisip for 7 days or 604800 seconds. The problem is when freeswitch restarts, it loses all these registrations and none of the linphone clients that were registered before will receive any calls until they reopen the app. I have a couple idea on how to solve this issue, but none that I want to go down today

1. • change the registration to 6-12 hours and flexisip should wake up devices to resend registrations This idea was based on a concept from belladonne, but relied on a feature that does not seem to exist
2. • make a script that goes through all the flexisip registrations in the redis database and sends a push notification to all the devices that will make them re-register
