External outgoing and incoming Voice Delay.

Hello Everyone. I have problem on our phone lines. 3 to 5 sec delay.
My 3cx is deployed on Google Cloud.
The ping from pbx to voip the latency is 134.491 ms.
is this bad?
What would be the best latency for no delay on voice.
And what I could do the reduce the delay.
Do you have settings to be adjust on the 3cx dashboard?
Or adjust something on the GrandStream WiFi ip phone?

Hi @phvoip

3-5sec delay is 3000-5000ms so I suggest to try first and isolate where most of the delay is.

1. Connect to the webclient from the same site as your phones
2. Have another person do the same from their pc
3. Call each other's extension to see if there is any delay between yourselves

This will help you evaluate the delay from your office to the cloud server. If there is no delay (or very little) then you would have too look into the provider/trunk you are using.
