[asterisk-users] 20min waiting time

[OCOSA ListAcct]

I apologize if this question has already been answered / asked. I was 
searching on Google and nothing I do will work. All that happens is that 
the phones ring for 00:01:15 then voicemail kicks in.

My goal here is to let the phones ring and ring until someone is not 
busy. I think 20000 secs is long enough.

Here is how the dial plan is setup

exten=>5,1,StartMusicOnHold
exten=>5,2,Dial(SIP/support&SIP/support2,20000,tr)
exten=>5,3,VoiceMail(455 at mailbox)
exten=>5,4,PlayBack(vm-goodbye)
exten=>5,5,HangUp()
exten=>1222,1,VoiceMailMain(455 at mailbox)

Any help is appreciated....
