Processing telephone number

["Angel L. Mateo" <amateo@um.es>]

Hi,

	I have an openldap that stores information of my users. One of the 
fields we are using is telephoneNumber to store the phone number of the 
user.

	In this field we are storing now the complete phone number, that is, a 
number like +34 123456789, but now we are deploying applications that 
need just the extension number (the last 4 digits), not the hole one.

	Is there any overlay or other option we can use to provide those last 4 
digits of the telephoneNumber attribute without needing to store them in 
another different attribute?
