[Emil Ohlsson]

Thanks, 

I actually ended up using the MESSAGE(from), which included the sender.

Br,
Emil

Since MESSAGE requests are serviced on a single, special channel that
is not a SIP channel, chan_sip specific functions/variables will not
work on that channel.

The MESSAGE_DATA function will read headers off of a received SIP
MESSAGE request:

https://wiki.asterisk.org/wiki/display/AST/Asterisk+13+Function_MESSAGE_DATA

You can also add headers to an outbound SIP MESSAGE request using that
same function.
