[Linphone-users] Registration stops working after some days

[Markus Wolters]

Hello,

I use a linphonec version 3.12.0 on a raspbian base. Linphone connects to an 
AVM Fritz!Box as SIP server. My problem is, every now an then (days) linphone 
gets disconnected and isn't able to reconnect anymore. The following log shows 
a reconnect attempt. Unfortuantely I can't figure out why this happens and how 
to solve it.
