Re: [Linphone-developers] MESSAGE Channel [0x7d38856a00]: inactivity timeout reached

[Marc Bohets]

The sip re-registration timer is imposed by the VoIP provider.

Initially, a sip client may send its preferred registration time to the sip server, 

but it is the sip server (= VoIP provider) that decides on the registration timing.

Nobody can comment on what this inactivity timer is all about and why
it's making it's consumer (linphone-android) re-REGISTER every hour?

I can see that it's being set to an hour here:

https://github.com/BelledonneCommunications/belle-sip/blob/1d083c76be5b5959db2cc1f52a61836d8f43aa7f/src/sipstack.c#L137

But is the intention of this timeout really to force consumers to have
to re-REGISTER based on this timeout?

Perhaps the intention is that that is just the default and consumers
are expected to set their desired value with:

https://github.com/BelledonneCommunications/belle-sip/blob/1d083c76be5b5959db2cc1f52a61836d8f43aa7f/src/sipstack.c#L298-L300

Is it reasonable for a consumer, a SIP client, say, to set that timeout
equal to the user-configured SIP Expiry period?

Cheers,
