One interesting system

Qnewbie

This system seems to be interesting:
http://www.zwcomm.com

One server?(EPS-104) is placed in Peking(or HK), four ATAs(EPT-101) placed at other offices. Using DDNS, you can connect these 5 offices and use the PSTN@Peking(HK). No VPN required!

Wondering if the PSTN call forwarding feature is included.

Just realise and simplify the needs of human for telephony. The box is not expensive and acceptable for most people.
