Professional Call Recording


VoIP (Voice over Internet Protocol) lets you access phone services over the internet. Calls are no longer dependent on old traditional phone lines. VoIP achieves greater functionality at a lower cost for businesses. This innovation means that communication expenses are much cheaper than traditional phone services.
Mainware clients report cost savings up to 55% after switching their communications over to its VoIP service. These modern phone systems such as Cloudcall Hosted PBX include many business features that boost productivity and revenue on top of the call savings.

You will need a VoIP provider, a stable interconnect connection, and depending on your office setup, you may need some additional hardware to enable VoIP to work. Mainware also recommends a ViBE or L2TP router to secure calls to stop hacking and improve quality.

For businesses with IP Phones that are SIP enabled, you will just need the SIP account details from your VoIP provider.

For businesses with TDM PBX’s, a VoIP gateway will be required and a SIP trunk from your VoIP provider.

For businesses with an IP PBX you just need a SIP trunk from your VoIP provider.

For Hosted PBX clients, VoIP is native to the setup so you will just need a solid internet connection.

In general VoIP requires a stable connectivity line to stop voice jittering due to packet loss or delays in speech. Data usage such as internet browsing, email and video streaming on the same line is not advised unless a VLAN is used. A VLAN takes a portion of the connection and blocks it off purely for VoIP, so no data can interfere with the VoIP traffic. Not all connectivity providers can/will provision VLAN’s.


The call quality of a VoIP systems depends on the speed and reliability of a customer’s internet, as well as the quality across the VoIP providers’ network. Customer’s end user device (IP phone) plays a part with modern-day devices such as Yealink IP phones enabling HD voice quality, allowing VoIP to outperform PSTN / landline (Telkom) voice quality considerably.
When listening to VoIP compared to traditional phone lines, you will hear a vast improvement in call quality compared to traditional landlines. Landlines don’t have as much audio bandwidth, which can result in muffled or fuzzy calls. VoIP calls achieve far greater clarity through HD voice technology. The number of HD Voice calls you can handle will depend on how fast your internet download and upload speed is.

The Mean Opinion Score (MOS) was initially developed to measure traditional calls and has been extended to measure calls on VoIP networks. MOS score is a rating from 1 to 5 of the perceived quality of a voice call – 1 being the lowest score and 5 the highest for excellent quality.

VoIP is by far cheaper than a landline services. PSTN providers such as Telkom charge high rates for calls, and because of this an entire VoIP industry was born as the VoIP providers use IP technology to carry the same calls far more cheaply. Estimates on call savings range from 25% – 55% depending on the mix of calls for a particular client.
Usually, the greatest call saving is seen on mobile calls (Vodacom / MTN and Cell C / Telkom Mobile), then landline calls (geographic and non-geographic landlines), special service numbers (0800 and 0860), and finally international calls.

VoIP providers can bill per second which further increases call savings.
If you were to combine a VoIP service with a Hosted PBX solution to replace your onsite PBX, you can drastically decrease your capital outlay and/or monthly hardware rental costs. Hosted PBX setups only use VoIP to carry the calls.

Mainware saves its clients on average 20% – 30% on mobile calls, 10% – 20% on landline calls, and up to 50% on international calls (destination dependent).
