The cheapest PSTN simulator on the market. This unit has 4 analog phone lines (FXS) making it a perfect tool for testing VoIP gateways, IVR, modems, access servers, audio conference equipment or anything that requires phone lines. Telephone line simulator acts like a "telephone company in a box" providing dial tone, ring voltage and all advanced phone line features such Caller ID, Call Waiting, Call Hold, Three Way Calling and many others.
Not only it can precisely simulate those features, it allows user to change or customize most of the call parameters such as call progress frequencies or voltage levels with a powerful Windows based management software.
Telephone line simulator is perfect tool to demonstrate functionality of any CPE that require analog phone line such as Fax machines or Fax Servers, V.90 modems, alarm systems, RAS servers, Voice mail servers.
Simulator is capable of simulating not only North American phone lines also several European standards including British Telecom.
Powerful real time logging capability allows saving call progress events to a file and analyzing those offline for troubleshooting.
