Hi All,

I tried to send this email this morning, but I think it has been moderated
due to size issue's, so I'll resend it again in 3 parts:

Hi All,

I have an issue with the ODBC voicemail storage option with asterisk. All
appears to work fine, however, I get several sql execute warnings. I was
wondering if anyone out there could help me get to the bottom of what is
causing this and how I could possibly go about rectifying it.

The warning message we are getting is as follows:

WARNING[30115]: app_voicemail.c:1280 delete_file: SQL Execute error!
[DELETE FROM voicemailmessages WHERE dir=? AND msgnum=?]

This warning occurs whenever a user leaves a message for an extension. It
also occurs when someone dials in to listen to their messages when they hang
up.

These messages do actually exist within the database, and asterisk does
extract them from the database when playing back or recording messages.

Here is an example when someone leaves a message for someone:
