V3 Cally Square

What’s about

Cally Square is a drag-and-drop IVR designer which provides useful tools to create and manage IVR applications for your Asterisk-based telephony system.

It is straightforward to create response applications using the various blocks including the others:

• Callback, Dial, Internal Dial

• Play audio

• Play TTS, Speech Recognition

• Get Digit

• Options menu

• Message Record

• SMS/Email Send

• DB integration

This section covers topics related to:

Open

• Managing IVR Projects, where you can create and design an IVR flow on the drag-and-drop HTML5 design area

• ODBC, where you can set different Database connections to be used on the IVR structure

• Recordings, where you can preview or download audio files recorded in an IVR project 

 

Benefits and use cases

The use of the Cally Square has several benefits:

• Intuitive Interface: easily design IVR applications using a user-friendly drag-and-drop web interface;

• Versatile Functionality: create Auto-attendants, surveys, callbacks, and more, all within a single platform;

• Time-Saving Templates: leverage pre-built examples that can be customized to suit your specific requirements

• Enhanced Call Routing: ensure seamless customer experiences by efficiently directing calls to the right queues or agents

• Integration with Asterisk System: build IVR solutions optimized for Asterisk-based telephony, ensuring compatibility and performance.

The following are some of the main use cases of designing IVR Scripts:

• offer a self-service to allow customers to solve their issues independently without speaking with an agent.

• allow you to record customized greetings and messages so that when your customers call your company, 

• Prioritize calls based on the caller's value. When a customer calls, the caller type can be extracted from a database, and IVR can route VIP customers to the most qualified agent to meet their needs. 

• connect to a remote DB (ODBC) to extract information

• use ASR to gather input and responses through spoken words 

• perform call recording

In a typical scenario of a company that uses an IVR, the callers are first greeted and asked to choose from a series of prompts (e.g. “Press 1 for Sales”). The callers are routed to the most appropriate queue based on the button they press. If all agents are busy, the caller will wait in a queue or managed differently.

IVR Performance

The purpose of this paragraph is to provide guidance on workload based on different concurrent IVR scenarios on an XCALLY machine.

The tests were performed using 2 IVR campaigns that generate a different number of calls per test, which are managed by a Cally Square project that loops Playback files.
