I would like to say I was very happy with Challenger porting my lines over from another provider, it went so smoothly I couldn’t believe it myself. We had no downtime and it went very well and the staff are so friendly, thank you once again Challenger.
The technical skills demonstrated in finding out all of the telephone numbers and services at Capitol Taxis Newport with various providers, managing the process of switching us to SIP trunks with Autocab® from different despatch software are truly matchless.
Your team’s sound knowledge and the highest level of understanding of the most complex design and implementation issues at every stage of its execution are certainly exceptional.
The support team was extremely helpful, and they completed the project flawlessly, well within time frame given.

The team at Challenger really pulled out the stops.
When our internal telephone system failed, they managed to get us set up with a temporary number with a divert and have 8 new Yealink VOIP telephones programmed, dispatched and installed within a week. There was no disruption to business and, most importantly, no stress to me, top work Challenger, I can’t thank you all enough.
I just wanted to take a minute to congratulate Challenger on its customer service.
Having issues with O2 on a new site caused us quite a few issues. To call Challenger and have a resolution within the space of an hour is great, but then to find an added a loan phone to ensure all is working correctly is amazing.
