We looked at several other VOIP solutions and Sipdesk 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.
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!
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. Sipdesk resolved this issue with their softphone app, so now my customers can reach me on my mobile app at no further costs
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.
We were having issues with BT and integration with our online cab management system. Thanks to Sipdesk technical expertise these were quickly resolved. I have been with them for four years and have been recommending them since.
We have made many changes to our PBX system, adding users, changing our dial plans and voicemails. We have always found Sipdesk Support to be efficient and eager to deal with all our changes.
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. Sipdesk ensured there is no downtime, I am very impressed with their project management skills.
I was apprehensive about using a VoIP system, I called Sipdesk 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.
We operate from multiple offices, when customers were calling in, it was often a problem transferring calls between the offices. Sipdesk VoIP system resolved this by bringing in all the handset under one cloud solution. This made transferring calls seamless.
We have been using Sipdesk 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.
We really don’t understand IT or VoIP, but our Account Manager is very patient and has resolved many issues often not related to Sipdesk PBX. Nonetheless he has always supported us, God bless!
I knew very little about Sipdesk 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.

Friendly, efficient chat operators are always on standby
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!
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.
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.
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.
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.
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.
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.
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.
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.
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.
