Please stop the spurious errors in the logs !

I'm not sure why this isn't an error. We're being asked to provide a mailbox count for a voicemail user that doesn't exist in the system. That might be a WARNING and not an ERROR, but it does feel like something has been mis-configured.

What is the configuration that you are using that is causing it to be spammed out?

#include pjsip.endpoint_custom.conf

[112]
type=endpoint
aors=112
auth=112-auth
allow=ulaw,alaw,gsm,g726,g729
context=from-internal
callerid=device <112>
dtmf_mode=rfc4733
mailboxes=112@device
use_avpf=no
ice_support=no
media_use_received_transport=no
trust_id_inbound=yes
rtp_symmetric=yes
rewrite_contact=yes
{noformat}

This may be a bad interaction with FreePBX 12.0.x.x where it does not allow the entry of an empty mailbox even when an extension has none.

{noformat}
admin/modules/core/Core.class.php
                               } elseif ($keyword == 'mailbox' && $data == '') {
                                       $fields['mailbox'] = array("value" => $account.'@device', "flag" => $flag$
{noformat}

Note also it puts {{x@device}} and not {{x@default}} which prevent message indicators working.

What is the correct behaviour here in freepbx ....
# Should is be {{@default}} as a default
# Is empty the legal value that indicates no mailbox, and this is therefore a bug in freepbx, rather than asterisk spamming?
# Is there a non-empty value that can be set to indicate no mailbox?

Thanks.

It doesn't seem like it is a real ERROR, but maybe as Matt mentioned a WARNING would be most appropriate. I feel like NOTICE may be a little benign for this message.

Regarding FreePBX, you should open an issue with the FreePBX team on their tracker. This is the Asterisk bug tracker and to get the best help you need on the FreePBX side, you probably want the FreePBX developers looking at the issue.

1. I don't know, depends on what FreePBX is doing.
2. Not defining the mailboxes option would be a valid default for "no mailboxes"
3. No.


If you can attach an Asterisk debug log showing where the issue occurs then we may be able to tell better whether message is being generated appropriately and get a better idea about the debug channel type.

Raised: http://issues.freepbx.org/browse/FREEPBX-8812
Freepbx should allow an extension to have an empty mailbox name.
By: Graham Barnett (GrahamJB) 2015-02-20 17:43:09.705-0600

Warning is a reasonable compromise. Raised issue on freepbx that they don't allow empty mailbox name for an extension.
Thanks.

I can't recall all of the reasons FreePBX does this, but IIRC, there are some reasons under the hood why they 'fake out' the mailbox. I vaguely recall it has to do with their symlinking that they do. It probably isn't a bug in FreePBX, but it is a case that {{app_voicemail}} considers on many code paths to be indicative of a configuration error. It's just something that FreePBX has learned to exploit :-)

I think demoting it to a WARNING is appropriate.
