I've purchased a Siemens Gigaset S685 IP Duo phone set and a new Linksys WAG160N ADSL Router. The router has been configured with QoS enabled and SIP-ALG disabled.
I've managed to configure the Gigaset with 2talk and VoIPtalk (UK) with no problems.
I have had one of my numbers ported across to Xnet VFX Asterisk. No matter what I try I get "Registration failed"


I have managed to configure 3CXphone with my VFX settings. With 3CXphone I can make outgoing calls over my VFX IP line but can't receive incoming - I get no such number. If I dial my number on 3CXphone I get number busy (correct!).
On advice from WxC port forwarding for my Gigaset host has been set up for TCP/UDP 8060-8070, TCP/UDP 5060-5065 and UDP 35384-37384.
Any ideas?
