Summary:                    MeetMe conference does break immediately.
/var/log/messages shows dahdi error
Description: 
I want to establish a MeetMe conference using
[...]
exten => 1234,n,MeetMe(1234,Mi)
[...]

As soon as the command is called, I receive from Asterisk:
    -- Executing [1234 at default:4] MeetMe("SIP/alice-08e96c18", "1234,Mi")
in new stack
  == Spawn extension (default, 1234, 4) exited non-zero on
'SIP/alice-08e96c18'.

/var/log/messages indicates problems with DAHDI:
Sep 11 18:43:29 server kernel: [6478913.125872] ioctl32(asterisk:10499):
Unknown cmd fd(17) cmd(c00cda0d){t:'Ú';sz:12} arg(f652783c) on
/dev/dahdi/pseudo

I use asterisk-1.6.2.0-rc1 compiled from source.
I use dahdi-linux-2.2.0.2 compiled from source.

I am running Asterisk on a Xen virtual machine (domU).

IIRC, I have ordered a 32 bit running on a 64 bit host. However, I am not
100% sure here, I will check again with my hoster. It seems more from the
uname output (I checked also /proc/cpuinfo, there is long mode (lm) flag)
that it is 64bit guest on 64bit host...
