AFAIR, there was an option you can set when you send the request to Google/Apple to mark the push as a "high priority push". Apple itself has also a specific VoIP push, (it's a different type of push, not regular push). it should be what you are using for VoIP related stuff. Not that this will speed up things, but it might make a difference when Google/Apple have issues delivering push notifications. 

I think that is as much as you can get.. from that point onwards, there are just too many variables out of your control that can add extra delay in receiving a push notification.

We have a suspicion that the delay is caused by Google and Apple being busy pushing "spam" to the whole world. A lot of messages, which does not require "real time".

When it comes to speed at which things happen, nothing in wireless is impressive when we are talking about telephony. :)

Hello

I have a question to those of You who uses push via Google or Apple to
initiate calls.

How long time does it usually take, before the phone gets the push and
wakes up?

Our experience is, that it can take from 2 to 10 seconds, and that not
impressing when we are talking about telephony.
