Upgrade
The BX3S does not have a dedicated custom ringtone upgrade interface, so the ringtone file can be uploaded through the software upgrade page.

The BX7, BX7C, BX210, BX210i, BX4U, BX5U, BX6U,BX7A, and BF600S support ringtone upgrades on the ringtone upgrade page.

Settings
1. Set a ringtone for a specific line.
Go to Line ---- SIP Advanced Settings, then set Ring Type to Music 1.

2. Set a ringtone for all lines on the phone.
Go to Phone Settings ---- Voice Settings, then set Default Ring Type to Music 1.

If the line advanced setting is set to “Default”, that line will use the ringtone defined in “Default Ring Type”.
