Paging Volume

[ITSteve]

When paging, the phones beep loudly, but when we begin talking, the voice volume is not loud enough. Is it possible to force the phones to use a specific volume?

Or, is there an easy way to do it differently? Using multicast? Or connecting to the office audio system speakers?

If it is easy to set the phones to a specific volume for paging that would be the easiest fix. If not, then I am open to whatever the best practice is.

Using the phones with 3CX pbx.

Thanks.
