Best Telephone Systems for a Call Centre


Your call centre telephone system should work with you to increase your revenue. It is your gateway to the world and when working efficiently, can make a big impact to your bottom line. You need to be able to have your phone system work in harmony with your software to reduce time between calls, thus increasing productivity; and ensuring data is tracked all through one system.

We reviewed the top systems on the market and rated them in terms of cost, ease of set-up, adaptability to changes in the office and remote working.

You can choose between VoIP call centre solutions or analogue phone systems. Each has its own merits. VoIP uses the Internet to transfer data. It is the most popular choice among call centers because of the lower domestic and international call rates. It also has a host of sophisticated features that the modern call center needs and offers fast, easy set-up. There are still some problems with a VoIP system, since it uses the Internet, you need to have a good Internet connection otherwise your call quality can suffer and you may experience a lot of dropped calls. An analog system, on the other hand, is reliable and time-tested. This system does not need the Internet so phone call quality is much better. You can also use this system in case there is a blackout.

In terms of cost if you are looking for low monthly charges in terms of set-up, upgrades and maintenance then a hosted PBX call centre solution is for you. However over the course of many years, you might find the hosted PBX system more expensive, an onsite system involves a high initial outlay, but then it is yours as you go forward with no monthly rental. Also, a point to note that if you go for a hosted PBX call centre the company providing the software will also provide the calls, so it is worth checking their call charges before you sign up. Don’t be lured into a low monthly fee for a software and then get stung with high international calls. It is easier for a company to add some extra features to the standard packages as a buyers incentive, to then add some hidden costs later.

Whether out are after inbound or outbound call centre solutions, both VOIP and analog offer a good solution.
