Summary:                    No DAHDI channel available for conference, user
introduction disabled (is chan_dahdi loaded?)
Description: 
The following error will consistently occur in an Asterisk 1.8 environment
when trying to dial-in to a MeetMe conference when the server does not have
Dahdi hardware installed:

app_meetme.c: No DAHDI channel available for conference, user introduction
disabled (is chan_dahdi loaded?)

This will cause user introductions to be disabled, including name
announcement, etc.

While chan_dahdi IS loaded correctly during compilation and install of
Asterisk/Dahdi, including associated modules, etc., a chan_dahdi.conf
configuration file in /etc/asterisk is not created if hardware does not
exist, causing MeetMe to think it can't open a dahdi_dummy channel.

Remedy to this is to rename the chan_dahdi.conf.sample file to
chan_dahdi.conf and restart Asterisk--this error will go away and the
introductions will work just fine.

Since I've seen numerous unanswered posts when searching Google to try and
find an answer to this, I thought I'd file this as an issue to get the
chan_dahdi.conf file created automatically for the above scenario so it's
not a manual process.

tested and confirmed, when no chan_dahdi.conf file is present, the
introductions don't happen and the error messages is printed, but the
conference still works fine. Once an empty configuration file is present,
it works as before.

The error was reported with FreePBX initially, where we do not provide a
chan_dahdi.conf file unless the user loads the DIgium dahdi configuration
module, but that module is not needed when no hardware is configured...
