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.
