Simone Zanardi, the editor of Italian famous PC magazine PC PROFESSIONALE, values DrayTek VigorIPPBX 2820 with compliment “a new and all-in-one IPPBX with versatile features for small and medium size companies”. Furthermore, the Digit Map provides simple and effective mechanism for users to utilize the least cost routing (LCR) for calls.
With VigorIPPBX 2820, there are unified communications of 4 voice channels through IP for the built-in ISDN interfaces and PSTN (analog) phones. The integrated two BRI ISDN ports consists of 4 B channels. The 4 B channels with multiple subscribed number (MSN) facilitates outbound/inbound calls directly or through connection of ISDN PBX. With IP PBX functionality, users can establish up to 50 IP-based extensions locally and/or remotely. The configuration of user name/password for IP phones can be done by Web User Interface (WUI) of VigorIPPBX 2820. After that, the auto provisioning will send configuration to connected VigorPhone 350 IP phones to speed up user’s installation. Users can establish 6 SIP accounts for simultaneous connections (incoming/outgoing calls. The SIP trunk providers such as ITSPs applies different tariff for on/off net. The users of a small or medium size company can pick the right combination to make distance calls. Along with Digit Map, users can select best value SIP automatically based on number dialed. In addition, the calls to subscribers to the same ITSP are established directly across the Internet. The SIP calls without PSTN involved will not spend call costs.
The DID ( Direct Inward Dialing) facility is also called as direct dial-in. It allows an call to route into a single extension or Group of phone numbers. It is very useful for a company to combine several extensions as one hunt group for handling incoming calls (e.g. sales team). The VigorIPPBX2820 is deployed with auto attendant to respond incoming calls with welcome message and company information (divisions, business hour, extension instructions) by interactive voice response (IVR). A company can record relevant messages via IVR. Alike traditional PABX, the VigorIPPBX 2820 are designed with rich-featured supplementary services such as music-on-hold, voice mail, and call barring restricts certain types of outgoing calls.

The multiple PPTP, IP Sec, L2TP, L2TP over IPSec protocol enables versatile configuration for necessity of VPN configuration among business CO/remote sites/tele-workers. With a dedicated VPN co-processor, the hardware encryption of AES/DES/3DES and hardware key hash of SHA-1/MD5 are seamlessly handled, thus maintaining maximum router performance. The Gigabit port of LAN switch maximizes uplink for the execution of unified communication applications, secure mail server, web server, CRM, and FTP server. The primary WAN interface is for connection to ADSL line. Through other Ethernet-based Internet feed, the second WAN port can be be backup or load balancing. The USB port can be connected with a 3.5G USB modem as backup while primary ADSL line drops. Besides that, users can connect USB disk or hard-drive to USB port for file sharing.
