Sprint/Google Voice double calls to voicemail

[knyque]

I have been eagerly anticipating Sprint not charging for the call forward, and it seems like they have finally done it.

I just activated that with my phone by dialing *28xxxxxxxxxx (the x's are my GV #, I followed the directions from GV), and tried it out. When I call my cell phone, it rings like it should, and I ignored it (both by hitting 'Ignore', and waiting, then stops ringing on the cell phone (but not the phone I'm calling from) for about 3 seconds, then rings again. If I ignore it again, it goes to GV, but it takes double the time for the caller to get voicemail, and it shows up as 2 different calls in my log.

Is this normal? Is there anything I can do about it?

Thanks in advance
