I did successfully, both with a hardware and software SIP phone. For the
software SIP phone I used SJPhone (on PDA), for the hardware SIP phone I
use the Linksys SPA3102. I tested the following clones: voipbuster.com,
voipcheap.com. A friend of mine uses voipdiscount.com.
Note that Betamax does have a support forum, but their employees don't
visit them that often.

Yes you can, but to have a username and password, you have to download
the client once, register and enter the details in your device.
Afterwards, you can uninstall the client again.

Seems something is blocking your communication.

You don't have to forward anything at all. Port 5060 must be available
outbound but not inbound. Note that some modems have port 5060 in use,
e.g. Thomson SpeedTouch 510 (and perhaps many others).
