Hi,
We have a 3cx instance hosted at AWS. This for a hotel. The hotel is 30 units and a Grandstream GXW4248 is the main device at the property plus a two soft phones.
3cx is saying the call quality is poor for all the analog extensions but not for the softphones. Rest of the network gear is Cisco router and a simple switch. The GXW4248 is connected directly to the Cisco router.
We have a fiber connection (100MB/100MB).
What can we do to improve call quality??
Edited to add that the RoundTripTime is 2000+ ms for the analog extensions as reported by 3cx call monitor.
