If you regularly call the same department at a company that uses an automated assistant menu (press 1 for sales, press 2 for tech support, etc), try this trick on Android and iPhone.
Dial the number and then a comma for each extension
e.g. +15707088788,4,2 takes you straight to the domain name tech support department at Network Solutions.
- +15707088788 is the international customer service number
- 4 is the first menu option (tech support)
- 2 is the next menu option (domain names).
