Thanks Warren, that's what I'm looking to do.

First question is where did ${MACRO_EXTEN} come from, I assumed
${EXTEN} is a built in variable?

Secondly, where would the 1 and/or area-code need to be placed? Could
an additional argument be used to specify the prefix, i.e. a third
variable be specified in the outbond-context to implement the
OutboundDial macro, or is the MACRO_EXTEN suppose to be an
implementation of this?

exten => s,n,Dial(SIP/{$ARG3}${MACRO_EXTEN}@vitel-outbound2)

As Jeroen mentioned previously a goto may be used, would this help,
seems similar to what I am trying to accomplish.

exten => _NXXNXXXXXX,1,Goto(1${EXTEN},1)
exten => _NXXXXXX,1,Goto(1555${EXTEN},1)

Thanks,
Stephen
