Need to forward calls to external number

I need a little guidance on forwarding incoming calls to an external cell number.
Can someone help? Below is the extensions.conf portion of the configuration that I’m working with.
I’m assuming it may be simple, but I haven’t found an example that works yet. Thank You!!

Extensions.conf
; Joe User
exten => 121,1,Macro(stduser,SIP/x121)

Sip.conf
[x121]
; Joe User
type=friend
host=dynamic
secret=*********
context=users
mailbox=121@default
callerid=“Joe User” <121>

Your next step on the 121 exten can be a DIAL with the trunk details and the number like(assuming you are susing a sip trunk called line and you want to dial the number 123456789):

; Joe User exten => 121,1,Macro(stduser,SIP/x121) same => n,Dial(SIP/line/123456789,30,TtwWXx)
