I am trying to change the transfer ringtone for Sangoma s705 phones either blind or attended. Using PBXact on-premise with Asterisk 16.15.1.
In Advanced Settings I have changes the values of the alert infos for the two relevant fields. But have not seen any changes from the phones. I have also pushed config via Endpoint Manager, and rebooted several of the phones.
Are you using a custom ringtone, or you are using one of the Sangoma ringtones?
If a custom ringtone, can you confirm that the ringtone is actually on the phone? You can do so by navigating and selecting that ringtone on the phone.
