Using dial command to a ring group

Hi,
It is possible to use the dial command to call a ring group

exten=> s,n, Dial(SIP/)

What channel type I should put instead of SIP to call the ring group or are there any other command to do that?

Thanks

no, use the Goto command.

exten => s,1,Goto(ext-group,[insert no. here],1)

thank you
