Send incoming text message to multiple extensions (using voip.ms)

FreePBX Tips and Tricks
1

Hello,

Thought this might be useful for some… I use FreePBX at home and have a single DID with VoIP.ms. I wanted incoming text messages to be re-broadcast to all the extensions in the house so everyone can see the message. When someone then replies to the incoming text message, I wanted the reply to be re-broadcast to all the extension so everyone knows a reply was sent. I also prefix the reply with the sending extension when it gets re-broadcast to the internal extensions.

To set this up:

  1. Set the Message Context to sms-in for the VoIP.ms trunk.
  2. Set the Message Context to sms-out for each extension that you want to send text messages from.
  3. Add the following code to the extensions_custom.conf file (Found in the Admin → Config Edit page).
    a. Note that you will need to skim through the code and update your pbx address, which extensions you want to forward too and your voip.ms server.

exten => _.,n,Set(HOST_TO=${CUT(MESSAGE(to),@,2)})
