Outbound SIP Trunk voice volume increase

[Sirius Admin use]

Hi guys, how do I increase the outbound voice volume. I have people complaining that our voice volume is low.

I double checked the data connection between the user 3CX app to Datacenter server, to Trunk provider and everything is under 8ms.

Kind Regards
Leo

Hi @Sirius Admin use

The volume is controlled by the endpoints and the provider. If you make calls from one extension to another do you have the same issue?

No not at all, if each other through GMS, it's fine. Whether he phones me or I phone him from 3CX my voice volume is lover.

In this case you will need to check your endpoint devices or contact your provider for this as there are no settings in the PBX to control the volume of the audio going out

The Codec Priority on that Trunk is below, would that make a difference?

G729
G.711 U-law
G.711 A-law

You can check what codec the provider is using and set the same codec to be the first in the list so that no transcoding is done to the audio which might help with the issue.
