VOIP Push for backgrounded app using Pushy

[Ayush Jain]

Hi All,

Am pretty new to apns. Please help me with a query related to Voip Push using Pushy.

With the introduction of APNS Http/2.0 interface, are we not required to use Voip Service Certificate, as previously by default VOIP Pushes sent using Voip Service certificate were considered as high priority Pushes ?

If APNS SSL certificate will work for voip as well, that means if my app bundle ID is 'com.sample.myapp', I would need to specify apns-topic as 'com.sample.myapp.voip' with apns-priority as 10 while using Pushy? And will I be able to receive these notifications using Pushkit to make sure they get delivered to app directly?

I guess Apple doc din't really link usage of Pushkit with the new APNS http/2 interface, & still in VOIP optimization guide (https://developer.apple.com/library/ios/documentation/Performance/Conceptual/EnergyGuide-iOS/OptimizeVoIP.html) , apple is recommending the usage of Voip Service Certificate.

Would really appreciate any response on the same.

Regards,

_Ayush

Oops—I answered this privately, but for the benefit of the wider audience, here's the summary:

> are we not required to use Voip Service Certificate…?

That's mostly true. If you're using the new HTTP/2-based APNs API, you can use a multi-topic certificate to send notifications to your app and to VOIP services. That said, old certificates are still bound to just one topic, and just switching to HTTP/2 won't change that; you'll need to generate a new certificate, too.

> I would need to specify apns-topic as 'com.sample.myapp.voip' with apns-priority as 10 while using Pushy?

That's my understanding, yes.

I'm not really sure about Pushkit in particular, and will have to defer to somebody else there.

Hope that helps!

Thanks Jon.

Am still not sure as of now whether we would be able to receive APNS Voip Pushes sent using APNS SSL certificate using Pushkit. 

Will update here once I get to know the same.
