asterisk users - Nov 2006 - Correct syntax to access a shell variable?

I would like to access my shell environment variable MYIP from within 
sip.conf to put in externip.

I've tried some variations of syntax after reading "The Future of 
Telephony" but it's not working yet.

Should it be
externip=${ENV{$MYIP}}
or some other syntax??

The right syntax should be externip=${ENV(MYIP)} but I **think** variables
are only allowed in extensions.* and not in sip.conf.

Right, they are.

As a workaround, use a trivial shell script (with sed -i) to rewrite the
IP address in the place you currently want to pass it through the
environment.

In sip.conf :

#include sip-externip.conf

sip-externip.conf:

externip = 1.2.3.4


A command to rewrite it:

sed -i "/^externip/s/=.*/= $MYIP/" /etc/asterisk/sip-externip.conf
