Android app push messages coming with delay

[alex.filip]

Hello

Please help us to find what is the problem with push messages to android phones. If phone is not unlocked (display off) more than 5 min, all push messages come after 2+ minutes.
No problem with calls, only messages. If Android phone is unlocked - message come instantly and these problem is with all Android phones (we use 50+ different phones with different android versions and different 3cx app versions - latest or beta).
All recommendations from https://www.3cx.com/docs/android-push-troubleshooting/ we implemented, even Enabled “Keep Active” feature but no results.
We tried to get the logs from 3cx management console with the Verbose option enabled. Can you tell me which log file we can find the information we need in?

One example from Android app log (with verbose logging enabled):
2023-10-10 16:08:00.238 14013-26488 I/3CXPhone.FcmService:Got FCM message, sent at 1696942520083, now is 1696943280236 (diff 760153 ms), TimeToLive: 86400s, priority: 2, original priority: 2

Hi there,
what DNS Servers are you using on the server?

 

[TheodorosG_3CX]

As a first step you need to ensure that the PBX is updated to the latest build
Also have you installed the PBX on HyperV?

Hi there,
what DNS Servers are you using on the server?

Own. Slit-DNS, available(resolvable) both from outside & inside with the same URL.

 

[Andrei373]

As a first step you need to ensure that the PBX is updated to the latest build
Also have you installed the PBX on HyperV?

Hyper-V - no, vm-ware. First question - not sure, alex.filip will tell you.

 

[TheodorosG_3CX]

Is the NTP installed on your HyperV?

No, it's not the latest, we plan to update it. But we have these problems from the beginning (different PBX versions).

 

[Ritter Technologie]

We saw it one some machines when the used DNS servers are too slow to resolve the Apple or Android push Servers, so try to change the DNS Servers to Google or Cloudflare and then test again

 

[TheodorosG_3CX]

At this point you need to update the PBX to the latest build as currently you are not able to activate.
As @Ritter Technologie suggested check your DNS.

 

[Andrei373]

Is the NTP installed on your HyperV?

VMware

Apple is OK, bthw

It is not a DNS problem AFAIC. Infrastructure is big enough, fix phones from both inside and outside is ok.

 

[Ritter Technologie]

The fix phones don't use or connect to push servers

 

[TheodorosG_3CX]

Your issue is the same on Wifi and mobile data?

 

[alex.filip]

Your issue is the same on Wifi and mobile data?

Yes, on both

 

[Andrei373]

The fix phones don't use or connect to push servers

but use the ulr string to connect to both sbc and pbx

 

[TheodorosG_3CX]

The PUSH is delivered from the PUSH servers of Google or Apple. It is not related with the ip phones or SBC.
As suggested ensure first that the PBX is updated to the latest build.

 

[Ritter Technologie]

Call comes in, the 3CX notifies the PUSH Servers, and then the push servers notifies the Smartphone

 

[Andrei373]

The PUSH is delivered from the PUSH servers of Google or Apple. It is not related with the ip phones or SBC.

Ok, no problem

Thx, we will try with the update, but like I said, the problem is from the beginning and every time the update (at that time) was the latest one.
