[Linphone-users] Linphone Android redial timeout

[funni . clonk]

Hello,
i have the following issue with the linphone app on Android:
Sometimes (means multiple times a week) when redialing from the call 
list I hear no dial tone. After a while I get a "408 Request Timeout". 
Re-registering via tapping on the green "connected"-led does not solve 
the problem. I need to restart the app completely. Sometimes i am too 
lazy and enter the number manually instead of restarting the app. After 
a while (f.x. the next day, i didn't measure it) it works again 
redealing from the call list. Entering the number manually or calling 
from the phone book works fine if the issue with the call list occurs. 
Therefore I don't see a problem in direction the SIP provider but in the 
linphone code itself. The dialing process from the call list seems to be 
different as from the phone book or the direct dial menu.

So how can we find the cause and solve this problem?

PS: As I have a managed phone I have limited access to it. For example I 
cannot install apps from 3rd party locations. Also ADB logcat should not 
work.

Best Regards
Chris
