Block VM's from SMS inbox

[b1gbleu]

The voicemails appearing as an sms appears to be a "feature" with V5.0 and is quite annoying. Having the phone beep and vibrate with its own sound using V4.6 was much better. I've tried the firewall option of blocking sms except by contacts but they still came through. I tried by phone # and it worked but who's gonna enter all those #'s? Not me. I remember when we had iden phones and I wanted to block the kids from texting I called Nextel. They told me vm wouldn't work without sms. Maybe that's related here, but like I said, I've had this phone for a year and this started with V5.0.0.1051.
This seems to be a problem only with Nextel BB's, because the other 83xx forum members report the settings for allowing only contacts worked.
