Create Tel: links in tasks

I would love the ability to add a clickable “tel:” link to tasks.
I often have to call numbers listed in the task, and this would save dialing them.

A tel link is like this: 123456789

Ditto. Any plans to implement this?

As it currently stands:

In task descriptions, when viewed on mobile some phone numbers show up as clickable links, others do not. How the phone number is formatted does not seem to influence this (ie with () around area code, - or no- ),

Is there specific way to format phone numbers in task descriptions to ensure they are clickable on mobile?
