Using KooKoo to build a number masking system

One line solution to setup number masking in KooKoo:

Lets assume you want to mask the customer number to your delivery guy. Setup a button in your app and when the delivery guy clicks the button just make a http request as follows:{delivery_guys_number}&caller_id={masked_virtual_number}&api_key=XXXXXXXXXXXXXXXXXXXXXXXXX &outbound_version=2&extra_data=<response><dial>{customer_number}</dial></response>

That's it! Done! You can have a simple mapping array to map the customer_number to the masked_virtual_number and the system becomes completely automated.

The solution in long form:

Number masking solutions have suddenly picked up in the Indian cloud telephony market. Companies like Ola, Uber and others are using number masking solutions to provide privacy to their customers and driver partners.

Setting up a number masking solution is really easy in KooKoo. Developers have been using number masking in KooKoo since 4 years back. In this blog post, I will just provide a step by step approach to set up a number masking solution in KooKoo.

  1. Register for KooKoo and sign up for a paid account.
  2. Buy additional virtual numbers from the dashboard. Buy as many numbers as you want to mask.
  3. Setup your application URL in the dashboard. So, when a call comes in, KooKoo intimates this application URL and provides the cid(caller id) and called_number parameters.
  4. The called_number is your virtual number. Use that and apply your business logic(maybe do a database query to fetch the real number associated with the virtual number)
  5. Use <dial> tag to dial the real number.
Done. You have a full featured number masking solution. Since the logic is yours, you control which virtual number is mapped to which real number and can protect the privacy of your users. You can use the record attribute in the dial tag to record the conversation.

Another way in which number masking can be achieved is through setting up an extension for the real number. This way,you will not need to buy a lot many virtual numbers. If you are interested, please send us an email at and we will get in touch with you.

Integrating Arborjs with Angular to create a live calls dashboard

Arborjs  is a cool graph visualization library. Angular  is one of the best JavaScript frameworks and we have been using Angular in a lot of our front end development. When you handle millions of calls, proper visualization becomes very important. Without proper visualization, you can get lost in the mountains of data. So we spend a lot of time to come up with good visualizations to represent the data. Since we loved the cool way in which Arbor represented graph data, we could not wait to hook it up with Angular. Because of Angular's two way data binding, when you hook up Angularjs with Arbor.js you can get a dynamically updated visualization of graph data with cool animations. To give back to the community, we have put up the code online at Github . Basically we have created an Angularjs directive for Arborjs. Please feel free to fork the code and add extensions and use it for your own visualizations. The code is self explanatory with comments inline. Best way to get s

Mashing up Freshdesk with KooKoo for customer support ticket management

Sorry for the delay in writing a blog post. I have been caught up in too many things since last month(we are growing, so its all good :)) Anyway, this week I thought I will look at how we can use the latest rockstar startup from India, Freshdesk . Freshdesk, as most of you know is one of the best "Social Helpdesk" systems out there. I am sure most of you are already using Freshdesk to support your customers. In this blogpost I will explain how you can add telephony to the mixture. In particular I will show some code which you can use to : Welcome the caller by name Ask him to enter his ticket id Play out the ticket status Connect the caller to the correct agent handling the ticket. Luckily for us, Freshdesk has a very well defined API and it was a pleasure to work with it. The engineers were also very supportive and answered all my queries quickly. So lets get into the code directly. 1. First we need to get the caller information. For this we need to a
