[Serusers] conference calls

Hello, I am not sure if someone has set up a SER/Asterisk platform for conference calls but if they have I would appreciate some help! - I was wondering how I would modify the ser.cfg given in the onsip document so that when users dial a particular number e.g. 2222, they are forwarded to asterisk where a conference call can be set up. I have set up asterisk as follows: [Meetme.conf] conf => 12345 [extensions.conf] exten => 222,1,Meetme,12345. If someone could give me some sort of example, it would help a lot. Thank you, Aisling. -------------------Legal Disclaimer--------------------------------------- The above electronic mail transmission is confidential and intended only for the person to whom it is addressed.
