I used to write a phone number, in contact form, like this : 04.42.15.18.65 (for example). Now i can't write a phone number with dot between to numbers. Zoho Crm said : "It's not a valid number".

Plus the phone number format changed. Before it was : XX.XX.XX.XX.XX, now it's : (XXX)XXX-XXXX

I don't want it. 

How can i fix it ?

Thanks for your help.

Regards

Lionel
