Create Table For Phone Number Formatting?

I am trying to get my SQL create table to work for my phone number formatting and it is not. When I create the below code, the default is set to 3 numbers only.

CREATE SET TABLE dl_qpt_cqe.contacts, NO FALLBACK ,NO BEFORE JOURNAL,NO AFTER JOURNAL

(contact_id integer not null ,contact varchar(50) , jobtitle varchar(50), dept varchar(50), phone integer format '999-999-9999', phone_ext varchar(10), email varchar(50), constraint pk primary key (contact_id));

Is there some other way I need to format the phone portion so the default is 999-999-9999?
