and i each of them to x-lite account

i want when number 200 call number 201 also ringing at 202

in other word he ring 201 if he didnot answer , ring 202

My understanding of your question is that you want to cascade the dials given a certain timeout. Here is a potential solution with a 15s timeout between each dials.

exten => s,1,Answer() 
exten => s,n,Dial(SIP/200,15,r) 
exten => s,n,Dial(SIP/201,15,r) 
exten => s,n,Dial(SIP/202,15,r) 
exten => s,n,Hangup()

Before Hangup, you could also dispatch to the VoiceMail with something like

exten => s,n,VoiceMail(200@default)

Good luck!

Use a Ring Group or a Queue. You may have to install the modules from Module Admin.
