What is Distinctive Ringtone?
The Yeastar phone system offers Distinctive Ringtone (also known as a smart ring, caller ID ringtone, or ringtone assignment) is a feature that allows you to assign a unique ringtone or alert to a specific caller or group of callers. For example, if you configure the distinctive ringing for custom ring tone to “Asia”, the ring tone will be played if the phone receives the incoming call. This lets you identify who is calling without having to look at your phone's screen.
How does it works?

Distinctive ringtone feature allows certain incoming calls to trigger IP phones or Linkus UC Clients to play specific ringtones, making it easy to identify important calls at a glance. This feature can be implemented in the following ways:
On IP phone
IP phones identify distinctive rings by using a special signal called an "Alert-Info" header. Here's how it works:
On Linkus UC Clients
Linkus Distinctive Ringtone lets you assign unique sounds to different callers and types of calls.
That way, you know exactly who's calling just by listening to the ring.
You can set these custom rings for almost any situation: for a specific contact, all internal calls, all external calls, or calls coming from specific system features like IVR menus, ring groups, or queues. This feature is available on all Linkus clients — Desktop, Web, and Mobile. You can choose from 10+ built-in tones or even upload your own custom sound files for a truly personalized experience.
Common Business Use Cases for Distinctive Ringtone
Instant Priority Identification
Assigning a special, urgent ringtone for calls from executives and key clients helps leaders quickly recognize and answer important calls. This way, they can ignore less urgent interruptions and make sure they never miss a high-priority contact.
Intelligent Call Triage
Support and sales teams can set different ringtones for regular inquiries and high-priority clients. This helps them quickly identify and respond to important calls, making sure premium clients get faster service. As a result, teams can meet strict SLAs and improve customer satisfaction and loyalty.
Accelerate Lead Response
Sales reps who assign a distinct ringtone to new leads or key accounts can seize opportunities the moment they ring. This facilitates the critical "golden hour" response, dramatically increasing the likelihood of qualifying and converting a prospect.
Streamlined Internal Communication
Using a standard ringtone for internal calls and a more formal one for external calls helps employees (especially receptionists) know who is calling right away. This lets them respond with the right level of professionalism and makes communication smoother, without having to guess who’s on the line.
Ensure Rapid Incident Response
IT and operations teams can set a loud, persistent ringtone for calls from system monitoring or emergency hotlines. This acts as a clear audio alarm for outages or security incidents, helping teams respond faster and reduce potential business impact.
