PBX vs Hosted Consultancy
PBX vs Hosted Consultancy

Traditional PBX telephony solutions are known to be costly, hard to maintain and do not give your users the call quality they need. Hosted telephony is a telephone system that sits in the cloud rather than in your office meaning no costly PBX maintenance or upgrades.
