We have a Snom PA1 in our stores in a paging group with our store phones. 3CX is installed at our corporate HQ. At the stores, a user will make a page and upon hanging up the phone, there are three audible tones, which sound like a busy signal. I cannot replicate this at HQ. I am not sure if this is a 3CX thing or a Snom setting. I'm wondering if it's a latency issue, which would be why I can't replicate it. I do know it is not the Snom setting for Call Released Notification. Anyone else experience this and/or know how to fix it?
