VoIP over VPN （PPTP，IPSec，OpenVPN）

In commericial sector, VoIP over VPN technology is usually employed. For higher security, IPSec VPN is widely used for message communication between locations or countries. You may PPTP VPN for less secured environment. The setup for PPTP is much simple and easily configured. In general, two locations must have VPN routers such that the local network segment can be seen by the devices or servers located in either sides. As the result, other parties in between locations is very difficult to tap your message for checking.

咁我地是用帶有opven的路由器比較好呢?仲系用PC起一個比較好?或者租個VPS主機,裝上openVPN?如果每人每月都出一D錢一起租個VPS裝上openVPN是否更抵?

個人認為用帶openVPN的router或者租VPS

In order to speed up and simplify the VPN configuration, we may employ Draytek Vigor VPN routers. With these VPN routers, you can have a very secured VPN tunnel for carrying VoIP message without the influence from the national governing bodies.

Other forum does mention the use of VPN to get rid of tapping by some authorities in some countries. Please take a look at the following website:

As a result, we have to set up a VPN tunnel for our voip voice packets.
