I've found literally dozens and dozens of tutorials of how to deal with a voip push, but none of them, not one, make any mention at all of how to set things up prior to that, nor how to test the code they've just written.
Sure, you can send a voip push easily enough using a push tool or push script, but that's only part of the picture, none of these tutorials mention anything about actually making a voip test call to accompany the test voip push.
Are there any tools, or web portals etc. that can be used to generate a voip call to a handset to set the voip call side of things in addition to the voip push handling?
Also, none of the tutorials mention what's needed to be done by the app in addition to implemented code to handle the voip push, specifically I mean how does the server sending the push know which user is associated with the push token. Surely there has to be a step where the app performs some sort of sip registration with a server before it deals with a voip push.
None of these so called tutorials show any of that, all these tutorials just show a small portion of a whole, does anybody know of one that actually shows the whole?
