How to receive SMS ?


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
sake, how could I build my own SMS reception service with Asterisk
(1.6.1 or later) ?
Which channel (chan_mobile, chan_datacard,…

local channels and g729a voice quality


Hi, We noticed a very sharp drop in voice quality when using digium g729a
codec. The problem seems to happen if the A channel (caller's channel)
is a landline/mobile number contacted using the same outgoing provider
(as a local channel). It sounds like listening to a mono speaker on
low volume. If I use a softphone that is directly registered to our asterisk box

Compact, affordable x86 devices?


Hello I'd like to build a compact, affordable, fanless x86 solution to

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.

intermittent problem on 1.4


We're trying to forward an incoming SIP call from voipfone (UK ITSP) that
originated from a UK landline back up a SIP trunk to the same ITSP and on to
another UK landline number. UK Landline->voipfone->asterisk 1.4->voipfone->UK landline About 1 in 3 times the call at the final landline is silent and we see "RTP
Read too short" scrolling on the console log. Where do we start working out what's going on? Other than that the server is
working well John
