Denphone Telephone Systems and Solutions : Japan's most flexible PBX solution

We provide the Denphone range of PC/Linux based software PBX systems. Our solutions are based on the Asterisk open source architecture and support a wide variety of configurations and connectivity options.

Hardware choices are made depending on the number of phones to be connected, the desirability of redundant systems compared with budget expectations in order to find the most cost effective solution. The majority of our installations in the 200-500 phone range run on standard rack mount servers from vendors such as Dell or HP. We also normally recommend Dell or Yamaha POE switches although we do install Cisco switches where requested.

Denphone 500 MicroPBXShown to the left is the Denphone 500 MicroPBX. With support for 10 users it is an ideal solution for small offices. The MicroPBX includes answer phone services and all the other features one would expect to find in a PBX 10 times the size and 50 times the price. It is available from our webshop.

Denphone systems support ordinary analogue telephones, as well as IP telephones based on SIP, IAX, and IAX2. We also provide full connectivity solutions to the Japanese telephone network (SIP, Hikari denwa, analog, ISDN INS64, INS1500).


DenPhone has a wide variety of connectivity solutions to local Japanese carriers such as NTT (Hikari denwa SIP, ISDN, INS1500), Colt (SIP, INS500), and other local and long distance carriers in Japan.

We can also connect you to low cost IP Telephony providers in Tokyo Japan, the rest of Asia, and abroad to reduce your long distance and overseas telephone bills.
