Our Architecture
Our Architecture

Our core infrastructure consists of VoIP routers, MPLS Routers, Session Border Controllers, Switches, Inter-Connects etc. An example of a typical solution’s architecture is shown here.


Expand your business without disrupting the communication system, our PBX can handle up to 10,000 users on the same account.

Ring Group
Ring Group

Multiple phones ring on the same number so anyone in the group can answer it (and, with Xinix Cloud Service, the group members don’t even need to be on the same site). You can set it up to ring the phones in the group in sequence or all at once.

DIDs (Phone Numbers)
DIDs (Phone Numbers)

Direct Inward Dialing (DID), have a block or single telephone number for calling into your companies private branch exchange (PBX) system.

Using DID, you can offer individual phone numbers for each person or workstation within your company without requiring a physical line into the PBX for each possible connection.

Call Reports
Call Reports

View live call stats across users and sites. Analyse costs and duration. See your most popular destinations and which operators are receiving most of the calls, how many calls each of your phone lines are receiving and when your peak periods and days are.

Virtual Receptionist (IVR)
Virtual Receptionist (IVR)

Auto-Attendant (or automated attendant) is a term commonly used in telephony to describe a voice menu system that allows callers to be transferred to an extension without going through a telephone operator or receptionist. The auto-attendant is also known as a digital receptionist.

Call Queueing
Call Queueing

When a new incoming call arrives, it is assigned a position in the queue. The callers hear announcements about number of callers ahead of them in the queue and the estimated waiting time. After that, the specified “music on hold” is played, and callers are updated about their current positions in the queue and the estimated wait time.

The priority order in which agents receive calls can also be pre – programmed at DDI level. You can manage staffing levels by setting queue limits and pre programme the times, days and dates that staff receive calls.

Business Hours
Configurable Business Hours

Activate your office opening hours, have calls routed to voicemail or to other destination like call centres and mobile automatically during closing hours.

Call Recording
Call Recording

This page is only active if your provider has enabled the Call Recording feature for you. With the help of this feature, the users of IP Centrex services can record their phone conversations for later playback. On the Call Logs page you can view a list of recorded calls, listen to recordings and filter them for / from a certain period.

Depending on your needs, you may activate / deactivate Call Recording by selecting or clearing the check-box on the top.


On the Conferences page you can create and manage your conferences (virtual conference rooms). Schedule time and date of conferences, invite multiple participants with secure pin access.

Xinix VoIP Servers

You can start using it now

Setting up a VoIP account is as easy as pie. Just type in a few basic details and we’ll set you up automatically on our online portal. From there, you can play around with the basics without any costs!

You can use your smartphone to get started

Many VoIP users use their existing smartphones when they first start out. Just download one of the many (usually free) SIP clients to your device and you’re away.

It’s not expensive

Ready to begin? An internet phone service won’t break the bank. Much of the VoIP features are free, add a couple of extensions, build a package, dial out from anywhere and transfer calls between users.

Any device can be a phone

Prefer not to use a smartphone? Don’t worry: use a softphone on your laptop, desktop or tablet instead, most of which are also freely available. Of course, physical desktop handsets can also be used.

On-network calls are free

If you have multiple users on the same account, calls between extensions are free, wherever they are in the world. Other calls are inexpensive no matter how far away the recipient is.

It behaves like a regular phone system

You will be pleased to know that an IP PBX does all of the same things that a traditional phone system does, without all the maintenance and installation costs. We also provide ongoing development and upgrades.

Ultimate freedom

An internet phone service offers total flexibility and puts you in charge of adding or removing features at any time. This means you can try out new features or scale up and down as your business develops.

You can use multiple numbers

Want an 0800, a geographic and a non-geo number? No problem. Assign them all to one extension, or distribute them over multiple extensions. The system is completely flexible.

Calls can be recorded

Many industries face compliance constraints, and if you work in finance or healthcare, you might have to keep a record of your calls. Record them digitally and archive them for future reference.

The sky’s the limit

Our API is a way to build call functionality and data into other applications. Give your developers the freedom to integrate your telephony with other systems and develop new solutions for your team.
