[asterisk-users] Disappearing voicemail?

[Ken D'Ambrosio]

Hi, all.  Today, our receptionist got an e-mail saying she had a 55-second
voicemail... but the attachment was 0 bytes.  Turns out, so was the
message when accessed via the phone.  A quick purview of the logs turned
up this:

VERBOSE[14836] logger.c:     -- Playing 'vm-savefolder' (language 'en')
DEBUG[14836] channel.c: Scheduling timer at 0 sample intervals
WARNING[14836] file.c: Failed to write frame
DEBUG[14836] channel.c: Scheduling timer at 0 sample intervals
VERBOSE[14836] logger.c:     -- Playing 'vm-mailboxfull' (language 'en')

[Timestamps removed for readability; the latter four lines all occurred
within one second of each other; the first line happened two seconds
prior.]

Anyway, I went through the logs, and noticed that this had happened four
previous times.  Not enough, over the course of the four months involved,
to be overly concerned, but any time voicemail simply "goes away," it's
probably worthy of note.  Is this a known issue?  Is there some way around
it?  I've Googled, to no avail.

Thanks!
