Okay, so I finally found a solution. I pretty much used a slight modification of this post [How-To][APP]Visual Voicemail in CM7 - xda-developers
. Except I didn't use CM7VVM.zip. The utility wouldn't work on the Ascend.
Here's what's you need. A backed up MetroPCS stock image (which was important if you flashed your phone to CM7 mod anyway) and TitaniumPro which you can download from the Market. It's free.
1) Reboot your phone into recovery
2) Backup your current CM7 mod image (This will save you a ton of headaches with configuration files as well as activation issues on certain products. I had to call Napster to de-activate the phone from the previous MetroPCS stock install. Not to mention you don't have to redownload stuff from the market)
3) Restore your MetroPCS stock image and reboot
4) Once booted, download Titanium Pro from the market and backup your MetroPCS VisualMail app. This will also backup the data for it as well. (Your phone does need to be rooted in order to backup the data)
5) Reboot back into recovery mode
6) Restore your CM7 image
7) (You may not have to do this. I did because I had boot hang issues) Clear your cache and dalvik cache
8) Once your phone succesfully boots up, re-download Titanium Pro from the market (I had a root issue and had to re-install busybox. It could have also been a delayed response since I have a couple of things going on at work as well)
9) Back up VisualVoicemail Data only (If you don't already have the App installed, back up App then Data...Backing up app and data together just installs the app in my instance)
10) Load VisualVoicemail....you should see No Message which means it was successful.
I tested it by calling it, and all active voicemail messages were downloaded instantly to my phone.
I know it's a really long, tedious workaround...but at least you save a 20 minute phone call and the reps having to walking you through the configuration set up.
Option 2....like wisepegasus said go with Google Voice. It is a great service to use and will even email your messages to you. The downside is that you have to pay an additional $5 a month for call forwarding option to Google Voice
VisualVoiceMail which is free for any $50 plan on up....or
Google Voice and pay $5 extra a month
If you do decide to go with VisualVoicemail, I hope this helps.
