SIP Business Telephony and Session Border Controllers
Old phone lines are being switched off, and calls now travel over the internet. We move you to SIP telephony and put a session border controller at the edge of your network, so calls stay clear, the phone system is protected, and the office keeps talking when the line is having a bad day.
What is included
- SIP trunks from South African and international carriers, replacing analogue and ISDN lines
- Cloud or on-premises phone systems (IP PBX), or Microsoft Teams Phone with Direct Routing
- An on-premises session border controller (SBC) for stability: it protects the phone system from toll fraud and attacks, sorts out call-quality problems at the edge, and keeps internal calls working if the internet drops
- Quality of service on the network, so voice always goes first
- Queues, auto attendants, call recording and call reports where you need them
- Your existing numbers ported across
What you get
- Clear calls that do not drop
- Lower call costs
- A phone system protected against toll fraud
One engineer handles it from start to finish, so a change requested today can be in production the next day, once change-control documentation and testing are complete.
