Im using SMS successfully over VoIP. No problems at all. You however need to use a good codec.
However, I don’t use the MessageSend application, instead I use the raw SMS()
application.
This works by the SMS centre calling my fixed landline from a specific number,
I detect the callerid, initiate a SMS reception and then the SMS is in the
spool files.
If I want to send a outgoing SMS, I push a SMS file in the spool folder, then
initate a call to the SMS centre.
Ergo, incoming is like this (as early as possible in the dialplan):
exten => s,[any],GotoIf($[${CALLERID(num)} = 07409400000]?recvsms,s,1)
(where 07409400000 is your SMS centre number)
Then at recvsms:
[recvsms]
exten => s,1,SMS(in-${clid},a)
exten => s,2,System(/usr/sbin/mailbot sms ${clid})
exten => s,3,Hangup()
(where /usr/sbin/mailbot is a script that reads /var/spool/asterisk/mtrx
folder, and clid is a variable containing a random number)
Outgoing is like this:
Place a file named [RandomA].[RandomB] into /var/spool/asterisk/motx with the
following content:
da=[number you want to send to]
ud=[text you want to send, only GSM alphabet supported, composite messages NOT
supported]
Then create the following file into /var/spool/asterisk/tmp:
Channel: SIP/0740940000@YOUROPERATOR
Callerid: "[YOURNUM]" <[YOURNUM]>
Application: SMS
Data: [RandomA]
(where 0740940000 is your SMS center)
Move the file from tmp into /var/spool/asterisk/outgoing/ and the SMS will be
sent.

Ämne: [asterisk-users] Asterisk compatibility with SMS services
Can anyone comment on using SMS in conjunction with VoIP service using one of
these three VoIP providers: voip.ms, vitelity.com, flowroute.com? Are some SMS
services more compatible with Asterisk (i.e. SMS over SIP works perfectly or
not)? Is it best to use a different data channel for SMS messages (i.e. SMS via
HTTP, SMS via XMPP) instead of Asterisk's built in SMS application MessageSend
<http://www.anveo.com/faq.asp?code=sip_asterisk_sms> ? In order to develop a
web application for sending and receives SMS messages for business users, are
there any pitfalls in using Asterisk to handle the message exchanges?
