CASE STUDIES

Objective

To add VoIP capabilities to their office phone system and
enhance the overall telephone communications environment.

• Improve inter-office calling
• Add PC soft-phone capability
• Integrate click-to-dial into the inhouse CRM system
• Add voicemail and smart call redirection features

Solution

Denphone rolled out Asterisk servers in the Tokyo and Osaka
offices connected to the existing NTT PBXs via J1 PRI cards.
The two servers were connected via IAX2 over the office VPN
Dialplans were designed to route inter-office calls over the
new trunk connection, and allow full bidirectional connections
between legacy phones and new Asterisk IP phone. The dialplans
included use of Asterisk Voicemail and call redirection (cascade)
features. Click-to-dial scripts were provided to the IT department
for in-house developers to use. The PC applications Firefly and
DIAX were demonstrated as PC soft-phone solutions.
