Thanks for the reply to my earlier message. Guys I am having problem with Meet Me conference. I am using 7936 ip phone. Upto two persons can use Meetme number to conference. As soon as the third person dial to conference in he gets a busy tone signal. Now if I replace the IP Phone 7936 with 7940, then more persons can conference in using the Meet Me number. No sure what is wrong. Any ideas. FYI conference bridge is also configured.
