We have an application using a SIP trunk, which doesn't need registration. It works fine. Only there is one problem: If our system is down for maintenance and restarted, initial incoming calls can be refused for 1 to 4 minutes. (the SIP provider sends 'alive' checks every 1 to 4 minutes, after answer al works normal) Because it's an alarm system, we want it to be up and running as soon as possible. We could force a (useless) outgoing call which will activate the SIP server, but isn't there a more elegant method? Can we send some start command to the SIP provider?
