I was just wondering if anyone has ever gotten a solid answer from T-Mo regarding quality and dependability of calls while on UMA. Just today i had 2 calls go straight to voicemail. One time it rang one time, and showed as a missed call. Two times yesterday calls just showed up as missed calls.
That's just the incoming call problems.

My outgoing call issues included, but are not limited to:
Dial a number and get a "call failed" with three rising tones. It will sometimes take three or four attempts to get a call out.

Dial a number and get a fast busy signal. A few times.

I know I am not the only one to experience these UMA issues, and while I understand that UMA is new service and the bugs need to be worked out... Don't these seem like HUGE bugs for a mainstream product? Has anyone gotten a solid answer from T-Mo regarding these issues? If you have, I would love to see what they have told you.

The answer I continue to get is overloaded UNC's.
Or a undisclosed internal networking issue.
Or a software update is on the way...

thanks all!
