[asterisk-users] Incorrect voice mail format on transfer

[John A. Sullivan III]

Hello, all.  I'm running Asterisk 1.6.1.6 on CentOS 5.3 in a
multi-tenant environment with IMAP voice mail storage on Zimbra.  One of
our clients is having a problem when transferring voice mails from one
mailbox to another (option 8 in the standard voice application menu)
using their Snom 320 and 360 phones.

The end results is the final recipient cannot listen to the voicemail.
We also email the voicemails in this case (this client is not using the
Zimbra email system yet) and they receive an attachment with a name such
as "msg0000.wav49_gsm_wav".

As strange as it sounds, it almost appears like Asterisk is trying to
create a file with an extension of wav49|gsm|wav which is confusing not
only the email attachment but also sox which cannot find such a format
based upon file extension.  Here is what I see
in /var/log/asterisk/messages.

First, the user doing the transfer:

Then the recipient trying to open the transferred voicemail:

I've not been able to reproduce it in our lab but I can see and hear it
plainly happening for our client.  Has anyone else seen this? Is it a
bug or a misconfiguration? voicemail.conf has format=wav49|gsm|wav
