[OpenSIPS-Users] Question about run exec from route script periodically.

[Dmitry]

Hi Bogdan-Andrei,

Exactly. 

Script send a push via iOS server, the server send the push notification for wake up a client, it wakes up and send REGISTER to my proxy, and authenticated. Then the client go to background again. That’s all. 

I don't use nathelper module, because it is not make sense (client will not respond, because it frozen)

So, I need to concern about keep alive _useragent_ in DB by himself.

Hi Dmitry,

So, basically you want to do a kind of user pinging, but not via SIP (as nathelper is doing), but via PN, using your external script ?

Hi Bogdan-Andrei,

I've tested the timer_route, it works well. But ,as it turned out, my issue is broader. 
===
So, if I use the timer_route, it runs some logic at specific time. I'm imagine, that users will be more then 100, so 100+ requests at one time will send keepalive to iOS server...
Thereby, I'll try to rephrase my question:
How can I run an external script _periodically_ for keep alive _useragent_ record in location table, and do not do it simultaneously. I guess, I need to bind the logic to expires time of the acc. I can try to get it time from the location table, but maybe exists some graceful way for it?
BR,

Hello Dmitry,

Maybe the timer_route[] will help with this ?

Hello All,

I don’t found the info in google, so I’ll try to ask here.

Data:

I have some custom SIP client for iIOS with logic wake up via push notification and most of the time it working in a background. The client send REGISTER in first time and go to the background. Now I have a special _useragent_ for next steps for detect it as my app. When a caller try to call to special client, opensips detect _useragent_ and run php script for send push notification (before send INVITE forth) to iOS server and will wait 2 sec in async mode. In this time, iOS client (callee) receive push, “wake up” and send REGISTER to opensips. So, registration completed, we run LOOKUP route with search updated “Contact” data for callee.

==opensips router snippet ==

async(exec("/etc/opensips/ios/wakeup.php '$var(ua)' '$var(key)'", "$var(out)", "$var(err)"), LOOKUP);

===

My question is:

How can I run an external script (via exec/etc app inside the routing script) _periodically_ for keep alive _useragent_ record in location table? Something like a cron inside opensips maybe. I’ll glad to any ideas.

PS. For keep alive “normal” users I use nathelper directives:

sipping_bflag

remove_on_timeout_bflag

natping_interval

ping_threshold

max_pings_lost

 

BR,

Dmitry
