Preliminary VoIP Checklist

If you have made decision to go for VoIP system, then you can go through the VoIP Checklist below in order to assist you in understanding the VoIP’s requirements. Please note that VoIP Checklist is only for your reference.

Networking Environment

Item Descriptions
Have internet Internet for IP-PBX is solely used for outgoing calls. If there is no need to use VoIP to call out, you can continue to install IP PBX for your internal usage.
Broadband If you do not consider calling out, then you can ignore it. However, it’ recommended to have 1 Mbits upload and 512 Kbits download (normal Streamyx speed), as it is suitable for 4 concurrent calls. The higher the speed the better it is. Based on our past 7 years experience, 20 Mbits can support up to 100 calls or greater.
LAN environment VoIP over LAN is achievable as the LAN (local area network) needs to be installed in your office for internet network purposes. Basically every desk will have one LAN port. The LAN port can also be used for VoIP purposes. In traditional way, a phone will have to connect to RJ11 jack. However, we will only need LAN cables, and with only 1 port, you can separate to multiple ports with Switch or IP-Phones itself.
WiFi environment VoIP over WiFi is achievable by configuration, there is nothing to do with the VoIP system. As long as you have an IP-PBX, WiFi, and correct VoIP client, then you will be able to have VoIP over WiFi.
