VoIP Call Quality

1. What internet connection do I need?

Site Essence VoIP works over an internet connection such as fibre, LTE, 5G or ADSL, provided the connection has sufficient bandwidth for voice calls. 

2. Do I need a static IP address?

No.

The service is designed to work with a standard dynamic internet connection. 

3. Why might my calls have quality problems?

VoIP call quality depends partly on the quality and stability of your internet connection.

Your router can also affect VoIP. Some routers have SIP ALG, which can interfere with VoIP calls. 

4. Will VoIP work during load shedding?

Your VoIP equipment and internet connection need power and connectivity.

If your router or internet connection goes offline during load shedding, your VoIP service will be affected as well. A UPS or inverter for your router can help maintain connectivity.
