Remove need for Area Code on SIP

[focusandrew]

Hi All,
Hoping to find the answer here.
We have a client who uses SIP trunks provided by Gamma.
Everything works 100%
They don't however want to dial the area code when they dial out, they just want to dial the 6 digit local number.
So at the moment they have to dial 12345 123456 but they just want to dial 123456 for local numbers.
I can do this all the time on ISDN but with SIP it seems to behave differently, how to I make this work?
Thanks
Andy

In your ARS table, match telephone number XXXXXX; and dial 12345N on the line group

Note the semicolon after the 6 X's
