[Asterisk-Users] Building a small Office EPABX with VoIP GW with Asterisk

[Sanjay Arora]

A small office with 2/4 VoIP ports, 6 PSTN & 16 Analog Extensions
requirement and a couple of high quality IP Phones (if required to
improve call quality). What are the pros & cons and costs for the
following options:

1. ATA with required VoIP port, 8 x 16 Analog EPABX with six PSTN
lines plugged in & 2 VoIP lines (to be selected as outward PSTN line
for outgoing VoIP call). If required, a couple of IP Phones.

2. ATA, Channel Bank, Analog Phone Mix. IP Phone if required.

3. ATA. IP Phones and couple of analog phones from a small card, for
locations that do not need outward calling/VoIP access.

With regards.
Sanjay.
