| Most of the IP-PBX/SIP servers available today are
high-end products that can accommodate 500 to 1,000
users, or more. Their initial cost is not less than
a few million yen, which has been a considerable roadblock
keeping a lot of small- to medium-sized businesses from
adopting VoIP. To encourage more customers to adopt
VoIP, Hitachi Cable will release the AquaVocal series,
middle-range VoIP solutions suitable for small- to medium-sized
offices of up to 200. AquaVocal contains various functions
in its compact body, including PRI*13
and PSTN*14
gateways; the software can also be upgraded to support
IP-PBX. Other major features include Web-style interfaces
for function settings, and outstanding maintainability
such as remote maintenance and backup flash memory for
quick system recovery in case of trouble. By combining
products that have SIP, PBX, and/or IP routing functions,
the system can be flexibly tailored to meet a wide range
of user needs, from use with the existing PBX and telephone
network (Step
1), to partial introduction of IP telephony
(Step
2), to full introduction of IP telephony
(Step
3). The system can be extended step by step,
with only necessary components added as needed, helping
to curb investment costs by allowing the use of existing
equipment. |
