Nick,
Pretty much - it builds the XML output on the fly, and delivers it
over HTTP (PHP/Apache).
It "works the same" for all of the mainstream Linksys kit - including
SPA phones.
Generally, where we've installed IP phones, we've also installed an
Asterisk appliance in the form of a Linux box, so those ones we
provision via TFTP on-site.
We've not yet had any problems with security. Please let's talk of
that no further now :p
We don't disable / lock anything. We don't want to become one of
"those" providers. Our customers buy their CPE, and thus probably expect
to completely own it. We have information on our web which shows the
customer how to (reasonably) easily get the unit to start provisioning
itself against our prov server again. Alternatively, we get them to
establish it's LAN IP, then send them an email with a link to click
which does this for them.
Where available, the latest firmware is sent to the device as part of
the pre-provisioning process.
Differences between PAP2 and PAP2T are:
- Plainer packaging - more "OEM" style
- LED colour
- No "stand-up" attachment (which could lead to overheats, given the
vent placement)
- PAP2T supports T.38
- PAP2T has more RAM
- PAP2T is *supposed* to be able to handle 2 concurrent G729 calls -
but it can't
- Different chipset
