Mexuar Communications Ltd is a software development company that specialises in Webphone, Softphone, CTT (click-to-talk) technology and bespoke communication applications. These are the tools you will need to bridge the gap between the internet and telecommunications. For more information go to and subscribe to our RSS feed.

Available now from Mexuar:

Mexuar Corraleta™ Technology a development kit enabling you to skin your own web based phone, communication tools and click-to-talk solutions.

Mexuar Corraleta™ Connect a click-to-talk solution ready to be deployed to your telephony server complete with administration tools.

Let's take a look at both of these products in more detail.

Mexuar Corraleta™ Technology allows Asterisk developers to implement “click-to-talk” applications.

Deployment of click-to-talk functionality can be implemented on the website of any size of business. With this feature, any website visitor can use their web browser and PC to make free calls and talk with sales or support staff in the company’s contact centre.

Corraleta™ Technology takes users from a web page to a VoIP call with a live customer service agent within 10 seconds. These calls are pure IP from the web browser to the customer contact centre PBX and are free, irrespective of the location of the caller or contact centre.

The Corraleta-developed application can be used to initiate port 4569 IAX2 calls to the contact centre via a button on a web page using just their headset and microphone, or can trigger a callback from the contact centre to the user’s chosen telephone.

Application examples include sales and support services for online ecommerce websites, emails embedded with click to call functionality and pay-per-call online banner advertising.

Corraleta™ Technology uses Java to deliver VoIP across multiple browsers and 3rd party white label applications, providing tight, platform-agnostic integration between traditional phone systems and core business applications, whether on the company internal network or on the Web. The applet is only 125kb, so downloads in a couple of seconds. This contrasts with rival solutions that use ActiveX and work only with Windows platforms and the Internet Explorer browser.

So what does all this mean in plain language?

Mexuar's Corraleta™ Technology will enable open source installers to configure Asterisk to accept IAX2 calls from any webpage using any browser with Java 1.4 and above

There is no client or configuration required by the website viewer, it’s Click to Call in 10 seconds or less.
Take a look at the Corraleta Connect flash demo This type of solution can be created for ecommerce or supplied on a telephony server as Corraleta™ Connect.

Should the website viewer not have a headset or mic a “two legged outbound call” can be initiated. (e.g. like “Google ads”)

How can you profit from this?

• You can now go back to your existing Asterisk customers and upsell them on the benefits of browser to call centre Click to call connectivity.

• By installing a Mexuar license for whatever fee you choose and charge them for the implementation of this functionality.

• Use the Click to call functionality to outsell your Ayava/Nec/Nortel/Cisco competition.

• Click to call from a web page, Click to call from an email, Click to call from a banner are all going to be very big business over the next 12 months. Using Asterisk is the only way we know of today to implement Java based Click to call. Others such as eStara, Talisman and Busta use Active-X. Another advantage is Mexuar's Java app. has a footprint of 125kb. So your final app. is tiny, small enough to negate firewalls and NAT routers, compared to competitive product downloads of 20/30Mb.

• Build a hosted solution and offer this to smaller customers who do not have the requirements for their own Mexuar Corraleta installation. Here's a great example of a hosted service in Spain

• Build a 3rd party white label application using the Mexuar Corraleta SDK as the underlying technology. A good example of this is the application deployed by Aloha Tone in Hawaii. They also TV news coverage for their implementation of Mexuar Corraleta:

Mexuar Corraleta™ is compatible with the Second Life® World.

Everyday we see an increase in the number of networking, social and dating sites. Many already have a communication tool built-in, the predominant one being IM (Instant Messaging), but wouldn’t it be more natural to integrate ‘speech’ for your communications as we all have something to say!

Mexuar’s Corraleta is a Java technology applet that sits on a communication server that is so tiny you can initiate a voice call through your web browser within 10 secs. At only 125kb you can communicate without router and firewall issues.

Corraleta technology is browser based, its platform independent, there is no software to install and is used to make VoIP calls – these can be free calls - or you can break out landline and mobile connections.

One of our clients was looking for a way to communicate virtually through the Second Life® World and by using this platform an ‘Audio Hotspot’ would enable natural ‘speech’ communications rather than text. They designed a bar area and we looked at the best way of initiating the communications.

It was decided that when an avatar (a graphical representation of a person) walked into the bar area and sat on a bar stool Corraleta would become active. When there were 5 avatars sat on bar stools they would all be able to speak to each other.

This can also be extended into private chat areas and for businesses requiring confidential communications in meeting and conference rooms.

Charles Woods, Mexuar Sales and Marketing Director said ‘Second Life is a very well known virtual world. More companies are building meeting places, bars, virtual offices and conference rooms and they will all need to communicate’ he continued ‘Corraleta delivers real-time, person-to-person speech and is a natural voice communication tool for virtual and social networks’.

Mexuar Corraleta™ Email Click-to-Talk “Proof of Concept”

Our second “Proof of Concept” article takes a look at how you can talk through current CRM solutions using Corraleta™ and Corraleta™ Connect.

This is an innovative solution that enables rapid deployment of VoIP Click-to-Talk applications for online businesses.

With Corraleta, any website visitor can use their standard web browser and PC to make free VoIP calls to talk to sales or support staff in the company’s contact centre simply by clicking a naked URL or hyperlinked object on a company’s web page.

Now you can take this a stage further and implement the same free VoIP call from your emails!

When you receive an email from a vendor simply click on the link or object (Call Us button) and your call will be connected in under 10 secs. There is no need to download software, the java technology communication applet from Mexuar is so tiny at 125kb enabling you to push a call through the firewall. These calls are pure IP from the web browser to the customer contact centre PBX and are free, irrespective of the location of the caller or contact centre.


An outbound email can now entice customers to ‘Call Us’. In this Traction Corraleta Proof of Concept we actually inserted dynamically generated URL’s so that when a call was placed, the inbound caller was identified and a screen pop up produced.

Corraleta delivers click-to-talk 2.0 for business, enabling them to quickly deploy platform neutral applications to streamline communications, enhance sales and service, and deliver communication cost savings.

Mexuar have successfully communicated via emails using Traction™, Salesforce™, Constant Contact™ and Outlook®.

Walmeric chooses Mexuar's Corraleta for C2T Voice Application”

Walmeric Soluciones in Madrid have launched a new C2T (clik to talk) hosted service for companies wishing to add voice to their e-commerce web sites and shopping portals. They chose Mexuar’s Corraleta technology for reliability, quality and ease of use.

Corraleta is a platform independent application built around the Asterisk open source telephony engine and running on the Java Virtual Machine. Using a standard web browser and broadband connection, users dial the softphone and make a ‘live’ call in under 10 seconds. The call is initiated and carried through VoIP and can break out to standard PBX servers.

The system is highly secure: there is no software to install, thereby avoiding viruses; no ports are opened which could lead to firewall issues; and no routing takes place via unknown PCs or servers. Correlata uses IAX protocol, resulting in a tiny footprint of only 125kb for click-to-talk applications, and with easy NAT router and firewall transition. It also uses less bandwidth than Sip.

Walmeric supply their C2T solution within 10 minutes of the client paying for the service online. The client is supplied a softphone in the form of a customised ‘Call Us’ button and the dialplan is routed through Wamerics call service. The client can then deploy the'Call Us’ button on their shopping site or web portal.

Charles Woods, Mexuar’s global sales and marketing director, says:“Corraleta uses Java technology and, by developing a softphone application, it’s a powerful tool in bridging the internet and telecommunications. Walmerics solution enables the customer to easily add a C2T solution on the web site taking minutes to deploy rather than days. In today’s competive market it’s an extremely effective solution”

He adds: “Our applications support web users interacting directly with customer service agents and are proven to boost sales and overall service - especially in higher-value sales transactions. Corraleta delivers Click-To-Talk 2.0 for businesses, enabling them to quickly deploy platform neutral applications that bring significant cost savings.”

Antonio Moraques, Walmeric’s Managing Director of communications, comments: “Mexuar’s Corraleta technology is flexible and from the tests we made has the best audio quality. Our solution enables the customer to buy ‘On Demand’ and they are not tied into lengthy contracts. This is ideal for businesses that need to budget. Our customers can use C2T within minutes. There is also no need to download large software programs. It’s quick and easy to use, simply click to buy and click to talk – all in 10minutes!’

Mexuar Launches Low-Cost, Corraleta™ Vela Licence Management Solution

A new solution for software development companies to monitor who, when and how many clients are using licensed software.

Mexuar Communications is today launching Corraleta Vela-LMS, a low-cost solution for software development companies, enabling them to monitor the use of distributed licences.

With increasing frequency of software piracy and unauthorised use of software, Corraleta Vela-LMS is able to monitor and generate a report showing where, when and by whom it was used.

Charles Woods, Mexuar’s Sales & Marketing Director, comments: ‘When you grant a software licence the user does not own the software but has the use of it, as detailed in the terms and conditions of the licence’. He continues, ‘Corraleta Vela-LMS will help prevent unauthorised use and will protect the developers’ licensing scheme and intellectual property rights’.

‘Software developers need protection and by facilitating them with the provision of a product such as Corraleta Vela-LMS they will be encouraged to continue developing future products and return profit for their business.’

How does it work? When a developer or vendor supplies software to their customer a licence is created and stored in the database. When the customer comes to use the software a component is retrieved from the vendor’s server after checking the licence database and delivered to the application. The component retrieval can be set each day or periodically by the developer/vendor.

Corraleta Vela is available for purchase now for £199.00 +VAT.

To purchase Corraleta Vela-LMS contact Charles Woods charles(at)mexuar(dot)com

Mexuar Corraleta - Designing a Webphone keypad with IVR and DTMF

During 2007/8 we issued a number of press releases describing how Corraleta is used by our customers. We are often asked… ‘Can I add a keypad with IVR and DTMF?’... ‘Can I develop a click to talk solution?’… ‘Can I add you solution to my social networking site?’… ‘I want my customers to reach me wherever I go, how do I do that?’

Let’s take a look at the first and probably one of the most popular question; ‘Can I add a keypad with IVR and DTMF?’… the answer is of course ‘Yes, you can’.

Most of you are familiar with the terminology but for those that are not here is a brief explanation of what we are talking about. IVR (Interactive Voice Response) presents an audio menu to the caller, in our case it accepts a touch-tone (DTMF) keypad selection and provides responses in the form of voice prompts.

So when you see the keypad in your web browser a voice prompts ‘press 1 for sales, press 2 for accounts’ etc. This type of solution is commonly used by banks, credit card companies, utility service and survey companies.

Lavalife introduced an adult chat line that does exactly this. A keypad was designed and by using Corraleta they were able to create a full functioning pad to route calls to the right type of service. For more information see the Lavalife press release

You can easily test this by using the Faceless.html supplied with Corraleta (see the screenshot below). Then by applying your html skills you can create a keypad and hey presto you have a working solution.


Why not test this for yourself? You will need some knowledge of Asterisk, html and java. Send us an email request for ‘Corraleta 30 day demo licence’ charles(at)mexuar(dot)com

Today, 12th September 2008, Telecomabmex, Mexico have announced a new range of VoIP products and services. The new C2T (click to talk) service enables their customers to call sales and service companies from their desktop or mobile PC. A web browser based audio conferencing solution is available for companies wishing to make an instant conference call. Finally the same Corraleta™ voice technology is being used for mobile radio interviews.

The technology is developed by Mexuar under the Corraleta™ brand name. It is a platform independent application built around the Asterisk open source telephony engine and running on the Java Virtual Machine. By using a standard web browser and broadband connection users can dial the softphone and make a ‘live’ call in under 10 seconds. The call is initiated and carried through VoIP and can break out to standard PBX servers.

The click to talk solution is ideal for e-commerce businesses enabling the call centre to view the context of the call and identify from several pages the products the customer wishes to purchase. Not only is there the opportunity to upsell but also to make sure the customer is buying the right type of product.

Audio conference calls are initiated in a similar way. Simply open the company website and enter your user name and password when prompted. This page then becomes an active audio conference room on your PC! Many users can access the same page from their desktop PC, laptop or even mobile/cell phone. The calls are very low and in some cases free when using VoIP services.

Charles Woods, Mexuar’s global sales and marketing director, says: “Corraleta uses Java technology, the softphone requires no downloads, simply click and the call is initiated within 10 seconds. You can customise and brand your own solution, it’s a very powerful tool in bridging the internet and telecommunications.”

Juan Carlo Fenandez-Busto, Telecomabmex Director of Operations and Systems, comments: “We have added a button to our website & emails then within seconds our clients can chat with us from any PC. All you need is a broadband internet connection and headset or simple PC microphone and speakers.”

He adds: “Our applications will help increase the customers web experience. By implementing our solution a sales representative is available to any web surfer in just one click. In conjunction with a resident application we can open a window in the sales representatives browser and they can see the page you were viewing when you pressed the ‘Call Me’ button. Our solution is also used as a contact mechanism by our clients and as a way to enable remote interviewing in the Radio Industry.”
