I have a FB2900 that has two DSL lines and I now need to configure it so that I can use a Cisco VoIP phone. The phone connects to the Asterisk Server and allows me to dial out and others to dial in but there is no audio.
I've had a look around the internet and see I need to allow UDP ports 5060-5061 and 10000-40000 in from the Firewall but this makes no difference. Does anyone have any experience here that they can help me with please?
