This question is about multi countries with tel:
User X is in Canada
User Y is in Argentina
In my web form, I have select for country code and input for the phone number.
User X (for his profile) will select Canada (for +1) and type his number.
*** Problem :
User Y consulting his profile will have a rendered
<a href="tel:+1xxxxx" />
this would work if user Y was in Canada or in the USA, but user Y is in Argentina
according to a phone dial https://www.timeanddate.com/worldclock/dialingcodes.html
to compose from Argentina to Canada it is not +1, it’s +001
Is there a library or way to auto-detect and auto-adjust the origin phone vs the country of the visitor
