If you were using some sort of VoIP system where clicking on a phone number did something, a la an http or mailto link, this would make sense. For most users, I'd think slapping the # in a note or the task title should do the trick, especially now that we can print the notes.

It should be possible to integrate a phone provider like "jajah" with the phone number. Maybe RTM could even profit from phone-calls made by this feature?

I concur on adding a phone field. I use RTM for reminders of calls and it is handy to have a field to specify the phone

I'm also looking forward to this. Other people are looking for phone number fields as well, just spread apart a lot of topics.

If you're impatient you can use the "http://xxxxxxxxxxx.tel.QLNK.net" hack described in the last post here:

But this should be native.

i also think it would be nice to have the phone number at the top level - even if i have to make the call the old-fashioned way

agreed

It seems that people in this forum have been asking for tappable phone numbers since 2006 (!). And five years on it's still not done. Would be a good time-saving feature.

Can we please add a phone number field

pleased a click to call

I use RTM on my cell phone. Often times, I have a task to call someone with the phone number in the task. To not be able to click the phone number and initiate the call is barbaric.

Wow, 19 years and they still haven't added it in.
However, there is the option to add multiple independent notes. So:
I put my favorite restaurants in the reference section with links to their menu URL. Then, in the first note I create, I paste their hours of operation, save that, then create a second note in which I just paste their phone number.
I add a restaurant tag, so when I click that tag, I get all my favorite restaurants, then I can pick the restaurant and have their menu, operating hours, and phone number close at hand. It works pretty well despite the lack of a phone number field.
