How to receive SMS ?

Report
Question

Hi, I've read here and there how Asterisk could send SMS but I didn't find
much about how to receive SMS and forward them to an email box. 1. First of all, I don't think my telco would let me receive any SMS
my landline. 2. Maybe I could find providers selling this service for a monthly fee; 3. I could build and operate my own infrastructure. Given this asterisk-users mailing-list purpose, and for curiosity's

local channels and g729a voice quality

Report
Question

Compact, affordable x86 devices?

Report
Question

Hello I'd like to build a compact, affordable, fanless x86 solution to
handle my home landline. I know about the following two platforms: 1. www.pcengines.ch/alix.htm
alix1d + case 100€ Does "Availability >500" mean that it's just not possible to buy just
one item? 2. www.soekris.com/products.html?limit=all
net4501-30 Board and Case $175.00 Is the net4501 powerful enough to run Asterisk, considering that I'll
use an external VoIP gateway to connect it to my landline? Are there other manufacturers I should know about? Thank you.

Konference module issue

use my touch screen number then most of the DTMF digits don't get's my
asterisk....
But the same module work with asterisk 1.4.41 without any issue. So is it asterisk issue or konference module issue please guide me.....
