The client send REGISTER in first time and go to the background. Now I have a special _<i>useragent</i>_ 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.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>==opensips router snippet ==<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>async(exec("/etc/opensips/ios/wakeup.php '$var(ua)' '$var(key)'", "$var(out)", "$var(err)"), LOOKUP);<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>===<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>My question is:<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>How can I run an external script (via exec/etc app inside the routing script) _periodically_ for keep alive _<i>useragent</i>_ record in location table?
