Beyond 3CX: Softswitch PBX for carrier-grade voice networks

What clients say

Verified feedback from UK businesses using our telecoms, VoIP, and 3CX services.

I cannot see a better alternative Dave at IT Communications always goes the "extra mile" - most of us know this is a rare event in any field, let alone I.T. For VOIP ( a veritable minefield) - right now I cannot think of a better combination of 3cx & I.T. Communications.
By Alistair Roberts
Outstanding support and service, brilliant product After 12 months of nothing but hassle with another supplier, who simply offered no support to us and in fact did every dirty trick to block us moving away, I T communications went over and above in supporting our business and finding solutions that the other supplier simply couldnt do. We have had a seamless move over and our new system is brilliant, the support service and back up is friendly and remarkably efficient. We are a young company and do not have much IT knowledge, we wanted someone and something that could simply "take care of it" for us and that we could call if we needed something changed- we have found them. I normally steer clear of recommending anything to anyone, but this company and the product they supply- no worries, I would recommend to all.

Outstanding, efficient and friendly service We very rarely have issues with our phone system but when we need help, IT Communications provides the best help desk support I have ever experienced. Fast, professional and friendly help and advice is always provided. Highly recommended.
By Stephane Coinon
Fantastic Service. Quick, efficient and no fuss. Marvellous! Completed a couple of purchases viat IT Communications now and both have been seamless in processing end to end. Very quick turnaround for license key for 3CX and SIP trunking. Fantastic is all I can say.
By Paul Gunnell
Solid service and support is personal and timely We purchased the 3CX phone system from IT Communications two years ago. They assisted with the install and hooking us up to their SIP trunks. We have had no issues with call quality and no drops in the service.
By Paul Bourne
Excellent Service Signed up for an 8 channel SIP trunk to support our 3cx system, sales process was painless and the support excellent - highly recommended.
