[asterisk-users] Loss of devices registration (pjsip)

[Dmitriy Serov]

Good day.

Asterisk 13.7.2, res_pjsip.
There is a problem of loss of registration of several devices. This 
happens not on all devices, but problem devices a lot.
Below is the log of registration of a contact of one device.

Is suspect two things:
1. delete a contact after the contact is added. But, like, it's a 
feature of code that may already be fixed.
2. deleting a contact much earlier than the 90 seconds specified during 
the registration

Would be grateful for any clues.

Dmitriy Serov.
