We have used X-on for over a year now and have been delighted with making the change to them. The ability to configure your set up in house ensures that as the business changes we can adapt the phone system to match, and when things do get tricky and technical their support staff are friendly and happy to help.
Its not all been plain sailing, and getting used to the VOIP set up did take some adjustment but now it has bedded in our phone service has turned a corner and is now at a much better level our previous more traditional approach. The flexibility you get with this system to allow people to take calls from any desk is really useful, and the ability to have users operating across different sites offers the virtual call centre type approach.
We have had an outage, not long after we went live, and the problem was widespread but they do offer a mobile phone back service that can be turned on to enable calls to still be taken so the risk to the continuity of business was mitigated as well as could be hoped.
Its good to see that X-on are still developing and enhancing their product, taking on board feedback from their customers. Always a positive when the relationship with the supplier continues to blossom after you have signed up and paid.
Always happy to discuss anything further over the phone if anyone has specific questions about our experiences with X-on.
