I was having problems getting a Linksys PAP2T-NA to work with Pitney
Bowes mailing station so it could use its modem to dial home and
download postage/software updates. After scowering the web, I
couldn't seem to find a definite how to article on what settings were
needed. I finally came up some settings by combining the information
from various places around the 'net. I have typed out those settings
and included them below.
Are there any settings I should configure differently? Anything I
should add or remove?
I was using a Linksys PAP2T-NA with firmware version 3.1.15(LS), but I
would assume that these settings would be similar on the Sipura
SPA-1001, and the Linksys PAP2, SPA2102, SPA3102 ATAs.
Settings that have an asterisk (*) before them seem to be particularly
important, so please make to pay attention to them.
