I would caution against that approach. Analogue to Digital conversions 
often seem to have 'problems' - mostly related to hangup detection 
and/or echo. If you really do want to use analogue phones, then use a 
good quality channel bank to bring the analogue extensions into 
Asterisk, not low-end ATAs.

You also have to consider the value of your time. There's little point 
shaving a few pounds (or dollars, or euros) from the hardware cost if 
it's going to double the configuration time. And using 'cheap' 
components will add to your ongoing support burden for the system.

Cheap != good value for money.

Personally, I'd consider using something like the Snom 710. They aren't 
the cheapest SIP phones by any means, but they do have a very good 
remote provisioning and configuration system, which will substantially 
reduce the work you need to do in configuring handsets.

If your budget won't stretch to the Snom units, the Yealink range as 
suggested by another poster might be worth looking at. I believe their 
cheapest (is it the T18?) SIP endpoint can be had for around 35GBP - I 
don't know what pricing is like in your local currency of course. I 
believe Yealink do also have a fairly reasonable remote provisioning 
system, but unlike the Snom system, I can't claim to have used it in anger.

Kind regards,

Chris
