+ INS1500 PRI connection to the existing PBX
+ Secure Dialin Gateway

Solution:

Denphone installed an Asterisk server in the firm's Tokyo office. Connections were made to the in-house PBX system via a PRI card. A secure dialin menu system was developed to validate inbound callers, and provide them with outbound calling capability.
