Why not simply something like this:

exten => 123,n,Set(GROUP()=Mobile) ; Set group to the mobile
exten => 123,n,GotoIf($[ ${GROUP_COUNT(${mychan})} > 1 ]?next)
exten => 123,n(next),Goto(context,exten,priority) ; Skip over calling
your mobile since there is already another call in progress, ie, send to
VM, or retry your home/office/etc...
exten => 123,n,Dial(IAX2/provider/mobilenum)

On the next line, you could also just play some MoH and wait for 10
seconds, then loop around and try again, etc... but then you are
probably better off using the queue system with agents ...

Hope this helps somewhat...
