Hi,

I wish to maintain multiple phone numbers of contacts, thus I have 3 Phone number fields in contacts module, Phone1, Phone2 and Phone3. I wish to use telephony integration mainly for incoming calls. Thus to identify which contact is calling using incoming phone number it is important that phone number is unique in system across all the phone fields.

eg. phone number 123 is saved a Phone3 of contact1. I wish to block user from saving same phone number 123 as Phone1 of contact2.

Is there a way through which I can achieve such validation.

Zoho allow 2 unique fields per module except email. I have already made two other fields as unique in contacts module and i'm not able to set any of the phone number fields as unique. And setting a single phone number field is not helping in anyway either.

Please provide a possible solution.

Thanks in Anticipation.
