    As someone pointed out visual voicemail is stored locally. I wonder if the poor quality is related to free space on the iPhone. I haven't noticed any downgrade but I have over 8 gigs free. How much free space do the people experiencing problems have?

    VVM is probably stored within the "Other" category, like the OS itself. Someone correct me if i'm wrong.

    So the VVM local storage space might have nothing to do with the amount of actual free space you have. Anyone know the VVM storage limit?

    You'd be surprised at how many VM's some users have saved, with some messages running several minutes long. And don't forget most users also don't clear their deleted VM's either, so those also take up additional local space.

    I realized I had only listened to 1 voicemail message since I updated my phone yesterday to 2.1. Sure enough the voice is tinny with low fidelity. I can still easily tell who it is on the voicemail but the compression sounds a tad too much and quality has suffered. I can understand trying to keep the VM's data size to a minimum but I would raise that minimum just a little higher than what we have now.

    I had a voicemail saved previously before 2.1 and it sounded great.... now that 2.1 rolled out... sounds horrible... just must be the codec apple is using...

    This was the first thing I noticed after the 2.1 update. New and previously saved voicemails all sound terrible now. It's bad enough I can't even recognize my wife's voice on the messages. The quality of the audio is comparable to an 8-bit mono WAV file when I listen on the phone itself; if I dial in and retrieve it the old fashioned way, it's fine. There's no doubt that this is an Apple issue rather than the carrier.
    This is completely unacceptable, hopefully Apple will address it in the next release.

    Yes, here in CA the audio quality is terrible too. It's not a network issue, it has to do with the local phone codec.


    What's interesting is that when playing a voicemail through bluetooth, the "tinny" sound is gone. Perhaps bluetooth audio compression removes this naturally? or there is something wrong when the earpiece/speakerphone drivers are used.

    Also, the "tinny" sound everyone is referring to sounds a lot like the aliasing sound you get when you re-sample audio with a different sample rate. Perhaps the iPhone is sampling the voicemail at an odd sample rate (in comparison to the AT7T voicemail server rate)

    Yup. Add me to the list - I noticed the degradation of sound quality listening to the SAME messages that were already stored on the phone before the upgrade. I guess as long as I can still understand the message, it's okay, but obviously, an update should make things better, not worse...

    I'm having the same issue here with Voicemail only. What's interesting is that Voicemail playback is completely fine when playing through the Apple Bluetooth Headset, but sounds terrible as previously described when playing back through the phone or speakerphone.

    I noticed this earlier this morning and thought I was going crazy; it's like my voice messages all sounded "tinny" and compressed if that makes any sense. What's strange is they sound fine if I call my voicemail from any other phone other than my iPhone 3G. Add another problem to the list for 2.1 that needs to be addressed.

    At this point, I've been having issues with push mail (doesn't work consistently anymore), crashing apps, terrible battery life, and the tinny voicemail playback, I'm really wishing I would have stayed with 2.0.2 even with it's problems. It seems like Apple traded one set of issues for another set, and gave them to us as "improvements".

    I am having the same problem. The VMs now sound terribly downsampled.

    I reported this to iPhone customer support earlier today, and they said this was the first time they heard of this issue. The guy tried to say it was an AT&T problem, at which point I challenged him and said, "Then, why do the voicemails sound fine when listening to them from any other phone other than the iPhone 3G"? He had no response for that. I think we're in for a long wait with this issue.
