[Asterisk-Users] conference & sip

[Altus Snyman]

Good day all
I've installed asterisk with sip on my LAN,no special cards,if done
sip.conf and extensions.conf and all work 100,I'm using x-lite as a
client.
I'm trying to do conferencing.What I did was to has out the meetme.conf
looks like
[rooms]
conf => 9876
conf => 2345,9938


and extension.conf
exten => 9876,1,MeetMe,9876

When I go onto x-lite and type 9876 it gives me this error in asteris
*CLI> Apr 29 12:50:12 WARNING[-1221493840]: pbx.c:1198
pbx_extension_helper: No application 'MeetMe' for extension (ext_test_1,
9876, 1)
  == Spawn extension (ext_test_1, 9876, 1) exited non-zero on
'SIP/101-e43a'

Any Idea
Thanks
