Poor Network connection



I just went live with Zoom phone and am having an issue.  When I call out or from ext. to ext in the office I get an error of poor Network connection and no audio.  Then about 10 sec. later I get audio.  This only happens in office.    VPN to PSTN or VPN to VPN is fine.  Any Ideas?   Thanks

How familiar are you with your network gear and topology?  Desk phone or mobile app or desktop app or?

I could imagine this as a network issue with your firewall/router and the way it handles voice traffic going out and then back into your same network.


If possible you could try to test while bypassing the firewall/in front of the firewall or trying from another network like your home to see if the same issue exists?  This should help narrow it down at least.
