I want to validate phone number and extension. 

1. Phone number would be 10 digits long (only numeric).
2. Extension will start with \*55 and max 6 digits.

I placed a validation for phone number using below RegEx.

```
var regExOther = /^[0-9*]+$/;
if(!regExOther.test(phone)) //phone may have 9898123456 or *552341
{
    //my error flag
}

```

Current solution only works for Digits and not for extension (\*55....).

Any help would be appreciated.
