just a guess: if ser was shut down for some time and then started again, ser reads all the contacts from the database. Meanwhile all this bindings have expired and will be removed.

Hi,

I understand what you are saying, but I have had two specific events with all of the bindings expiring at once, and ser doesn't seem to be processing new register requests from 20 different devices. Then the phones become useless. This has only happened two times but it has not happened in the past week.

Hello,

Two times in the past week I have had some issues with the bindings

of the sip mapping expiring:

...

Binding 'user','sip:user@x.x.x.x:5060' has expired

Does anyone know what this is and why it happens?

Because it is not refreshed. Bindings are sof-state -- if not refreshed by new REGISTERs they will go.

I appreciate any input you may have.

Thanks,
