[Asterisk-Users] MeetMe conference

[Jain, Sonal]

I am trying to setup MeetMe conference.
In my MeetMe.conf file I have 
[rooms]

conf => 4001,4001
In my extension.conf file I have the following:
exten =>4001,1,MeetMe(4001|p|4001)
When I try to call the extension 4001 it gives me the following error message. I am using SIP and I have not created 4001 in my Sip.conf file. Do I need to create this extension and also how do I fix this error.
