[Freeswitch-users] newbie Question in two parts

I have three separate FS systems I running. I would like to be able to make a Mad Boss call from server A to Servers B and C. I found this page that tells how to connect two boxes. https://wiki.freeswitch.org/wiki/Connect_Two_FreeSWITCH_Boxes Question 1 - on this page the two server have difference extension. Is there a way to do this if they similar e.g. 1001, 1002 etc.. Question 2 - Can I make a Mad Boss call from one to multiple servers? If yes, can you point me in a direction to learn how to accomplish this task? Thank you in advance. Shawn
