Basic testing to be done before installing VoIP Line

1. Make sure that the VoIP port 5060 is available on the Internet line.

2. A minimum of 256 Kbps Internet bandwidth is required for a single VoIP line.

For testing use

3. Check the type of network you have i.e. Dynamic IP or Static IP. Usually Dynamic IP is the most used network type. If it is a Static IP, ask the customer for the following details

a. IP Address

b. Subnet Mask

c. Gateway/Router IP

d. DNS Server

4. If there is a local Firewall (Hardware/Software), please make sure that the Server IP/domain and VoIP device IP Address has full access on the firewall on both inward and outward directions. For Software Firewall, it is necessary that the softphone application (e.g. X-Lite) is allowed.

5. It is always recommended to separate the Data traffic and Voice (VoIP) traffic, as it may affect the VoIP QoS (Quality of Service).
