Without writing any validation rule on Phone field on Contact object, I am able to save phone numbers (with and without extensions) in the default “Phone Number” field on Contact records, and can save international phone number too (with or without extensions).
The phone field in my developer org accepted the following numbers:
512 757 6000 ext 4562
408 567 8900 ext 34
408 555 7000 ext 4
International Number
+91 9578909870
+01 (352) 000 000 000000
+01 (352) 000 000 000000 ext 222
+011 43 1 333 4444
+011 43 622 333 6789 ext 333
The only limitation on the default Phone Number field on the Contact object is that it limited to 40 characters as far as I am able to ascertain. Any comments, suggestions, or perspectives on this issue will be appreciated.
Thanks,
Neeraja

No. Validation Rules on Phone number field are not necessary, and I almost always advice against using them. You want your users to be able to add/update the phone number field with the information they have. Valid phone numbers can be in a really wide variety of formats and writing a VRule or rules to support all of them is not worth the effort since you don't really gain anything.
