I\'m creating a webapp to be used by iOS users, but some phone numbers in the database need to have extensions added on. Is there any way to modify the tel:// U
tel://
You can use 'p' to pause, for example, tel:12345678#123. By changing '#' to 'p' (or comma) will cause pause for extension.
tel:12345678#123 // original tel number tel:12345678p123 // after changed for tel scheme tel:12345678,123 // Use comma instead
