Hello! We would like to create app - custom SIP-client.

Unfortunately, we can't release push module on our SIP server. Please help us, and consult us how we can receive incoming call for app in background without push notification?

how we can receive incoming call for app in background without push notification?

There are two ways to implement VoIP incoming call detection on modern versions of iOS:

PushKit, which is based on push notifications
Local Push Connectivity, as documented here

The latter is only useful if you’re building an app for a restricted environment, like a cruise ship. For a general-purpose, VoIP you must use PushKit.

Unfortunately, we can't release push module on our SIP server.

Why not?

FYI, I didn’t see your responses above because you put them in the comments. See tip 5 in Quinn’s Top Ten DevForums Tips.

Still, I don’t think that changes my response. I’m not in a position to reverse engineer other developer’s apps for you. However, it’s possible that they are relying on the legacy VoIP infrastructure, which is no longer supported.
