Hi all, I have a Trixbox behind a Netscreen NS5GT. I want to have a phone that hooks into this Trixbox from a DSL Internet connection. I have created a new custom service and forwarded ports 10000-20000 UDP and 5060 both TCP and UDP, and created the appropriate firewall policies, but the phone refuses to register with the Trixbox.
I'm thinking it has to be something with the Netscreen - there is an in-built rule for SIP but it is not listed as an option when I try to forward it (hence creating my own service) - so I really don't know how to use it. I have disabled SIP ALG after doing some research but that has not made a difference.
Does anyone have any ideas? Thanks
