With most VoIP problems it is best to contact Support. However, here are a few pointers:

Unable to register

Check username and password carefully.
See the General VoIP settings page for registration details
See the VoIP clients page to see if your VoIP phone is listed and has any special notes
Check if your router has a SIP ALG - see: Disable_SIP_ALG

One way audio

One way audio is usually due to network issues where NAT is in use.

ie, if the IP of your phone is (for example) 192.168.x.x or 10.x.x.x or 172.x.x.x then your phone is probably behind a NAT router.

Take a look at the VoIP_NAT page for help with this and what we'd advise.
Check if your router has a 'SIP ALG' enabled. Disable this if so.

Calls breaking up (intermittent audio)

Generally audio problems such as calls breaking up are due to to the quality of the Internet connected that is being used. Diagnostics should first be concentrated on how well the internet connection is working.
