Algo 8028 SIP Door/Gate Phone

The Algo 8028 doorphone is an weatherproof/outdoor rated SIP intercom, designed to allow users of your Asterisk PBX to control access through a secured gate or door with the simple press of a button.

When a visitor presses the back-lit call button a single phone or a group of phones will be rang in the office. Once answered the occupants of the building are able to verify identity courtesy of the two-way communication with the visitor, after which they can dial the access code thereby granting the visitor access to the premises.

The doorphone can also be dialed directly from any user on the system to communicate with the visitor.

Open Source PBX

Asterisk is stable enough to support everything from 5 seat premise based PBX's to 500+ seat fully redudant contact center applications. The most enticing aspect of Asterisk is the sheer amount of features available and the open source licensing associated with them. While more features are added with every release, licenses for items such as voicemail, extensions, and even auto-dialers are long required. Open Source VoIP has truly revolutionized the IP PBX market! Asterisk continues to embrace legacy PBX features such as DISA, custom IVR's & ACD, while enhancing the value of your communications platform with features such as interactive flash based CDR's, click-to-dial applications, voicemail to email, real time monitoring, and operators transferring calls with the click of a mouse.
