Internet Calling for my 6700 running WM6 w/ SPRINT

[sheetalc]

I am very happy with Helmi's new WM6 rom. SO first off - thanks much to all those guys helping us around here!!

I have been trying to get Internet Calling to work on my 6700 with no luck. I have the Internet Calling option when I go to Settings->Today->Items. But choosing it gives me no tab in my Today page for Internet calling. I also have the "Voip Setup" program built into my rom and have correctly added my voipbuster settings to it. I know that my phone is correctly registering with the voipbuster server (because my PC softphone then automatically gets logged out!). But I still dont get any Internet Calling or Option to make Sip calls from the keypad (is that what you call the dialer??)

Can anyone please help? Thanks.

p.s: I have used SJ Phone and it works fine.. but its does not link into my phone contacts etc..
