Double check your firewall and: 1) ensure you've actually enabled UPNP and 2) Ensure that any mention of a SIP ALG (application level gateway) is turned off. SIP ALGs tend to really screw things up. On Wed, Oct 7, 2009 at 12:48 PM, Andy <andy@fabulous4.co.uk> wrote:
I've now set the external ips manually to be my external ip and have forward all ports through my firewall to the FS server. It's actually set up as a DMZ to everything is being forwarded without restriction but sadly DTMF and HANGUP messages are still not getting through. Have I misunderstood what is required. Is there some additional forwarding within FS required. I'm really sorry to keep coming back but I've been wrestling with this for a long time now and not getting anywhere.
