Regex for accepting all type of phone numbers in javascript validation -

i'm using below regex accepting phone numbers,

 /^\+?(\d[.\- ]*){9,12}(e?xt?\d{1,5})?$/;

but want accept following phone numbers also(specially indian mobile , landlines):

+91 9970464878 +91-22-22221500 09970464878 9970464878

you can add 3 possiblities start of regex.

this regex once used on similiar requirement :

^(?:(?:\+|0{0,2})91(\s*[\-]\s*)?|[0]?)?\d{10}$

note - have strip away hyphens, dont think required validations.
