  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?

• That’s pretty cool, thank you for the details. You are using the builtin SMS application that exchanges SMS data over SIP / PSTN connections. I
  don’t believe I can get service like that in Canada. Does anyone use the SMS applications to send and receive SMS messages in North America? Who provides that service?

• i’m using gammu[1] with a 3g dongle and my own chip with my preffer provider. It can send over 700 every our and receive to. I don’t know if you need asterisk and sms in the same way but with this tool you can make everything. It has python tools to.

  Best regards.

  Emiliano.

• I’ve used that, with an old pre-smartphone mobile as a GSM modem. It has the usual GUI frontend and scriptable backend. But it is separate from Asterisk.

  I have also used the OpenVox G400P/E in the past, which integrates beautifully with Asterisk (incoming text messages, successfully sent outgoing messages and failed sent outgoing messages trigger extensions in the dialplan); but this card has been “no longer recommended for new designs” for some time now
  (chan_extra won’t even build against recent kernel or Asterisk versions).

  Be aware that if you send too many text messages in too short a timespan, your telco might deem that to be in excess of their “fair use policy” — although the exact dividing line between fair and unfair use seems to be a jealously-
  guarded secret. The only way to find out for sure is to cross it …..
