Don't just take our word for how good we are

Umar Ahmed

We looked at several other VOIP solutions and Xinix always came out on top.

Very easy process to get signed up! Faultless call quality, array of call features and value for money calling bundle. 

Michael Hughes

Second-to-none level of support - always answering the phone, and explained solutions in a no-nonsense fashion. So far the best solution we have encountered!

Jenifer Gibson

Operating the business from home and also being the only staff things can get challenging especially when I have to leave the office un-attended. Xinix resolved this issue with their softphone app, so now my customers can reach me on my mobile app at no further costs

Charles Buckley

We increased our outbound calling records by more than double through their click to dial feature. Technical issues are resolved swiftly, can’t be happier.

Shamim Ahmed

We were having issues with BT and integration with our online cab management system. Thanks to Xinix technical expertise these were quickly resolved. I have been with them for four years and have been recommending them since.

Mike Coker

We have made many changes to our PBX system, adding users, changing our dial plans and voicemails. We have always found Xinix Support to be efficient and eager to deal with all our changes.

Kevin Dyer

Due to our expansion we have had to move offices a few times, luckily being on cloud meant we are not restricted to the BT exchange and have always managed to take our number with us. Xinix ensured there is no downtime, I am very impressed with their project management skills.

Nicholas Cheshire

I was apprehensive about using a VoIP system, I called Xinix and found the gentleman amazingly refreshing! He explained everything from start to finish and help me to set up the whole system to get my business working. The tech guys are also fantastic.

Usman Ahmed

We operate from multiple offices, when customers were calling in, it was often a problem transferring calls between the offices. Xinix VoIP system resolved this by bringing in all the handset under one cloud solution. This made transferring calls seamless.

Zairab Zabeer

We have been using Xinix PBX systems for 4 years. Growing from 2 partners to now over 34. We run a multiple office operations, transferring calls between sites as well as having the one receptionist managing all our incoming calls. Our Account Managers regularly travelling from London, a rare service in this industry. Highly recommended.

Liz Ejemole

We really don’t understand IT or VoIP, but our Account Manager is very patient and has resolved many issues often not related to Xinix PBX. Nonetheless he has always supported us, God bless!

Chris Clancey

I knew very little about Xinix apart from their website, but from my calculations of looking at our current bills etc, I saw that they were definitely one of the cheapest I could find. We picked the best product for our needs and ended up saving ourselves anywhere between £70-100/month.

Benefits of SIP Trunking and Call Management

Cost Saving

Thanks to multi-modal communication capability, SIP trunking enables you to save more than 30% on your monthly telecommunications costs.

Trunk aggregation

By centralising and eliminating redundant connections, you are able to use idle connections in one location for calls at another, thereby offering increased flexibility over traditional PRI circuits.

Flexibility

Depending on the needs of your organisation, the ability to add or reduce connection capacity is simple, thereby increasing the flexibility of the service you provide.

Simplified billing

By aggregating all the voice and data services into one product, you can take advantage of reduced administration with simplified billing.

Quality

By keeping communications data on pure IP connections as opposed to T1 PRI connections, SIP trunking offers improved voice and video quality, delivering almost HD-like audio.
