You need this for several reasons. Mobile devices may change their ip quite frequently and this re-register updates your connection to the server.
You control that in the account config structure. AccountConfig.GetRegConfig().set… there you have the flags for registertimeout, and the intervals that control the sip engine.
300 is the default of pjsip.
Our mobile apps run at 90 seconds while active and switch to 900 (15 minutes) when in background/sleep.

This behaviour is a SIP one. This is normal.
I don't know how to reconfigure pjsip to change the frequency of SIP REGISTERs.
The SIP REGISTER message is necessary to tell to the SIP proxy (SIP server) that the client is still alive. That is, the SIP server has the condition to knows that the client is still online. If the register expires and there is no more SIP REGISTERS, the SIP server will consider that the client is offline and will delete the client register from the registrar. Is the client that should decide how long a register will be valid. In the current case, I guess 300 secs is hardcoded somewhere.
Best regards.

Assunto: Re: Is this normal? Reconnect every 5 minutes?
Ah, ok, thank you :) ...didn't know that a SIP connection could expire. That may be the case... I'll have a look!
But this auto-reconnect that is performed on expiration would not happen when there is an active call ongoing, right?
Currently I am using pjsip only as a kind of notification service and not to actually talk to someone. But I plan to do this, too at some point.
In the log files where I save the status that comes back from pjsua I saw these "200 OK"s which occur periodically and precisely every 5 minutes (=300 sec) - that looked a bit surprising to me.
But I'll see if there is an expiration time that might explain this behaviour.
Thanks!
Oli

Look at the "expire" in the register, i guess it's at 600 seconds (5 minutes). If so, yes, It's completely normal.

Hi there,
currently I am using pjsua with Python 2.7 and everything works quite nicely. However what is strange is that pjsua seems to reconnect to the SIP server every 5 minutes?! Is this a default behaviour that can be configured somehow or what might be going on here?
What I see is that the SIP status becomes resent every 5 minutes (200 OK) although I do not manually invoke a reconnect! I assume pjsip internally and automatically reconnects to the server. But why does it do that?
Thank you =)
Kind regards,
Oliver
