You stated that you need to add some custom headers, which you can do with the
MESSAGE_DATA function.  In order to activate the forwarding, you could
do something like this:

exten => send_msg,1,NoOp()

; If something needs to go in the body, replace this.  Otherwise,
; you can just remove it
same => n,Set(MESSAGE(body)=hello world!)
same => n,MessageSend(sip:to_address)

Matthew, you used the name "send_msg" which I found confusing since extensions.conf is the dialplan configuration file. So an "exten =>" is triggered by either an outbound or an inbound call. I admit I may be ignorant, so could you please clarify how the message sending code you wrote above fits in the dialplan? How can it be triggered other than by an inbound/outbound call?

Since I didn't figure another way to do it, I associated your code with an extension. The idea was when the 101 extension is dialled, the SIP MESSAGE is sent to the provider:

exten => 101,1,NoOp()
same => n,Set(MESSAGE_DATA(X-Movial-Content)=application/x-movial-control;forwarding=true)
same => n,MessageSend(sip:54395135465@provider)

But when I test it I get two errors:

  -- Executing [101@house:1] NoOp("SIP/me1-0000000e", "") in new stack
-- Executing [101@house:2] Set("SIP/me1-0000000e", "MESSAGE_DATA(X-Movial-Content") in new stack [Jul 29 21:09:25] WARNING[32728]: pbx.c:10208 pbx_builtin_setvar: Set requires an '=' to be a valid assignment. -- Executing [101@house:3] MessageSend("SIP/me1-0000000e", "sip:54395135465@provider") in new stack [Jul 29 21:09:25] WARNING[32728]: message.c:992 msg_send_exec: No message data found on channel to send.


First, apparently Asterisk doesn't not like the syntax used for MESSAGE_DATA, although it seems correct... Could it be because the value also has a "=" sign?

Second, it complains "No message data found on channel to send". Maybe if the MESSAGE_DATA function was successful, this error would not show up. Or maybe I need to set an empty message body.

This feature of Asterisk is so new that there are almost no configuration examples of this on the Internet. So your help is really precious.

Tested with Asterisk 10.7.0-rc1


Thanks,
- Tiago
