What is VoIP?
As the name suggests, Voice over IP (VoIP) delivers voice communication and multimedia sessions (such as video conferencing) over IP networks. This means people can use the internet as the transmission medium for making phone calls. Consumer examples of this include Skype and WhatsApp calling.
VoIP technology can also be leveraged to enhance traditional PBX solutions while delivering modernised, flexible communication services over IP infrastructure.

What is a SIP trunk?
SIP (Session Initiation Protocol) trunking is a service that connects your business phone system to the internet, replacing traditional phone lines.
It allows your business telephone system to make and receive calls over the Internet, further reducing costs while improving call quality and flexibility. Think of it as a virtual phone line that enables VoIP (Voice over Internet Protocol) communication.
Visit our website or contact Saicom for more information on how you can incorporate this VoIP service into your business.
How does VoIP work?
VoIP uses codecs (programmes that compress data to enable faster transmission) to encapsulate audio into data packets. These packets are transmitted across an IP network and then decompressed using codecs at the other end of the connection.
By eliminating traditional telephony infrastructure (think copper-wire landlines), VoIP reduces network infrastructure costs and lets companies use their internet connections to deliver an integrated voice and data experience to employees.
Simplify your business phone systems. Contact us to get started with Saicom VoIP.
What is the difference between VoIP phones and normal phones?
A VoIP phone system requires an internet connection to make and receive calls while traditional phone systems use PSTN (public switched telephone network).
Even though both provide platforms for communication, ‘normal’ business phones are limited by analogue capabilities while VoIP services provide organisations with comprehensive digital offerings that can scale according to their requirements while delivering superior voice quality.
Contact Saicom to upgrade to a VoIP phone system.
What features does a VoIP system provide?
VoIP eliminates the need for telephone lines and third-party phone service providers by integrating with all major PBX systems and any network infrastructure, essentially reducing your call rates.
A business can port its number to our VoIP environment and access it anywhere in South Africa. Employees can connect through any internet service, including mobile hotspots, freeing them from office-bound phone systems.
VoIP systems deliver automated attendant functionality that routes incoming calls efficiently, alongside standard features like voicemail, call forwarding, and recording. This is a significant time and cost saver for remote working teams who need to be contactable.
Finally, VoIP providers deliver unified communications, integrating audio conferencing, video meetings, and messaging in one central platform. This creates a more effective way to engage with employees and customers compared to traditional phone systems.
