Some of the reasons to build a phone myself were:
<br>
<br>
-1 because you can ;-)
<br>
-2 the pi is made in large quantities and has a big community.
<br>
-3 up-to-date kernel
<br>
-4 huge collection of programs in the raspbian repository.
<br>
<br>
I hope it inspires someone to build a better model, smaller and
with a better battery life.

Interesting. BTW, i would recommends to use any recent 3G modem
instead of Arduino gsm shield. Some pros and cons:<br>
<ol>
<li>Cheaper (you can find one for something like 5-15USD on local
auctions)</li>
<li>Supports recent data (HDSPA+, etc.) connectivity as well as
SMS and Voice</li>
<li>Voice functionality already integrated with Asterisk
(chan_dongle), so easy to integrate with any VoIP software and
hardware<br>
</li>
<li>Can be unplugged any time and used as 3G dongle if needed :)<br>
</li>
</ol>
<p>I am using this configuration (raspberry + chan_dongle + modem)
as outgoing gateway to the mobile network. If i need this dongle
as backup ISP connection i am just unplugging it and all traffic
goes via backup SIP link :)<br>
