Can it be a modem/router issue? I've seen your king of problems when using some ADSL modem/routers. If you have not already done, try to change the following: in Outbound Proxy write 'us.voxalot.com:80'. You can try with the following UDP ports where I have putted '80': 443, 2060, 3060, 4060. Depending on what hardware or software you are using you may need to change the UDP port for registration to the same value that you use for the Outbound Proxy (with a Linksys phone I have no need of it).
Usually, the one-way-audio or the no-sound problem are NAT issues. Really, some routers behave strangely.
Regards.
