[otrs] How to add New Filed in PHONE VIEW

Hello Group, I need to configure the NewPhoneView Script by adding new field containing Customer information ("for Example A Text Field for special ID"). Is there any possibility to add a filed and store the values in the MYSQL database table “article”. I already made few alterations in AdminCustomerUser application by adding new field like phone number and Fax Number... are there any favorable way to make modification in NewPhoneView Script? If this is possible what are the changes I have to make in the script. Can any one help me. Thanks in Advance!! With Regards Kamal
