Does anyone have a good rule of thumb as to what the WAV or MP3 attachment size is for a recording/message that is sent from Voicemail to Email? I have customer that is not getting long recordings, in excess of 30 minutes, possibly up to 60 minutes long, delivered to email because their server is rejecting the message do to size... They are willing to increase the attachment size limit, but are not sure how large to set it.

I would assume that an MP3 file will be much smaller than a WAV file. FYI, our attachment limit is 25mb.

If converting to an MP3, doesn't that chew up a lot of processor power?
It seems I remember reading somewhere that doing a lot of that could cause issues.

Yeah, what I have discovered is that in WAV format, each 15 minutes of audio is about 20MB... Switching to MP3 is significantly smaller, but the time to encode a file is around 2-5 times longer from what I have seen, the longer the message the longer it seems to take per minute of recording to encode.
I will probably try switching a couple mailboxes to MP3 format and see what happens... There are only 3 or 4 people in this company that do long recordings, so if it works for a couple of them, it should be fine to implement on the others.

Weird... can't seem to get MP3 to work, it just X's out and disables if I set it and it still sends the message as WAV. Pretty sure you could do this before using Forward only or Forward&Copy.

I would assume that the wav file is a 64 Kbps CCITT Mu law, not sure what the MP3 would be. Might be bigger?
