Set Ringtones for Incoming Calls
This topic describes how to assign ringtones for incoming calls on your Linkus Mobile Client. You can set a default ringtone for all incoming Linkus calls, or assign distinctive ringtones based on different call sources, making it easier to distinguish calls from colleagues, customers, or specific contacts.

In addition to the ringtone settings on Linkus clients, system administrator can also configure a Linkus Client Distinctive Ringtone for specific call scenarios, including ring group, queue, or IVR. These PBX-assigned ringtones will be applied to Linkus when the users are members of a ring group or queue, or are set as IVR destinations.
If multiple ringtone rules are applied at the same tine, the following priority is used: .
