WM6.1 + VoIP (missing settings)

[beefviper]

I'm using a custom ROM, and I've tried a bunch of different settings and CAB files. But for some reason, under Phone settings, I never see the Internet tab (there are some others missing too).

I've seen some other people saying they had the same problem, but I never found an answer.

I'm using BuildOS, and have tried different version of the SYS files, tried including the VoIP package from BuildOS, also some different WM6(.1) VoIP CABs I have found in different places.

If I had some sort of error message, atleast I'd have something to Google. But there seems to be no error, except for the extra tabs in the Phone settings not showing up (also the Internet Calling plugin is listed in Today settings, but it doesn't show up on the main screen).

Finally figured out enough stuff so I could poke around some more.

The only setting I had to change after installing one of the VoIP cabs I had was one flag in one registry setting.

According to MSDN the default setting for "Features" under HKEY_CURRENT_USER\ControlPanel\Phone for a CDMA phone is 2B820, and that GSM cab you had was setting 206C7D8.

After combining the flags, and take away flags one by one, it seems the only flag that really matters is SHDFL_PHONE_LOCKFACILITY. (Doesn't really make sense to me, but it worked. I was expecting one of the other flags.)

That makes the setting 2B828 (instead 2B820)
