Adding unlimited optional digits

[vzelenko]

Suppose I want to create a mask for phone numbers that looks something like this:

(000) 000-0000[xEXT]

where [xEXT] is optional, and EXT can be any number of digits.

How can I specify [xEXT]?

you can try

1. using pattern + blocks with regexp inside
2. using dynamic mask
3. think that phones are limited in length and apply strict mask

Thank you. I used pattern, and limited phone number extension to a maximum of 6 digits.
