I have a Trixbox installation currently up and running. I’m using Grandstream GXP-2000 desk phones for all of the users. The issue that I’m having is that some of the phones are not synchronizing correctly. I have the settings in the phones UI to get the date and time from “us.pool.ntp.org”
They had been working just fine, though seemed to have stopped all of a sudden. Any ideas?
if your server is configured right, you should just point the phones to your FreePBX’s ntp server. The server should be sync-ing with an outside ntp server. No need for all the phones to go out as well (unless they are remote extensions).
