Oh, by the way, there was a small typo I just found in that post I gave you.

Here's the correct method:

Use for Telephone calls: On
Username: GV[insert your number here]@gvgw1.simonics.com
Password: [as provided] (secret)
Advanced:
Username: GV[insert your number here] or Username (ex.GV1234567891)
Transport: UDP
Outbound proxy: gvgw1.simonics.com
Port: 5060
Discover public address: On
Loose rouing: On
Keep-alive period: Automatic
Auto-detect STUN: On


In that link, it had
Outbound proxy: gvgw1.simonic.com
not simonics like it should be.

Sorry about that.
