Hi folks,
 
Just thought I'd post the solution to this problem. In my case the problem was that my config was based on an older version and so was missing a crucial parameter that exists in the default config wirth a new install.
 
The external.xml profile needed to contain the parameter:
 
<param name="local-network-acl" value="localnet.auto"/>
 
With this in place, DTMF and hangup messages traverse the nat firewall correctly. Without it they don't. I searched the Wiki and couldn't find any info on this parameter. Can anyone provide a description of what it does and why it's significant that can be added to the WIKI?
 
Cheers
Andy

PS chances are you have to ENABLE upnp.

Many thanks Brian, the firewall docs assure me it is uPnp but is probably lying or a poor implementation. Could you point me to the right section of the Wiki to tell me how to do this manually as I've been scouting for some time and can;t seem to find the right thing. sorry if I'm being blind.
