Hi,

Following Brendan's suggestion, here's what I ended up doing:

* I created a function that is loaded at init-time (i.e. sourced
through .emacs) as follows:

(defun N900-dial-number (the-number)
  "To send a number to the N900's 'phone application to dial it"
  (shell-command
   (concat "dbus-send --type=method_call "
           "--dest=com.nokia.CallUI "
           "/com/nokia/CallUI "
           "com.nokia.CallUI.CreateCall "
           "string:\"tel:" the-number "\""
           )
   )
  )

* I customised org-link-abbrev-alist to include
  ("tel" . "elisp:(N900-dial-number \"%s\")")
  as an entry to abbreviate "tel:" references.

Now I can add "links" into my org-mode files of the format
[[tel:1890365365][Banking365]], and emacs will ask me to confirm this,
and when I tap "yes", then I'll get the dialler with the number
pre-filled.

The request for confirmation is a security measure to prevent
executable links in org-mode being maliciously placed into the file
and hidden (e.g. [[shell:rm -rf /*][ILUG website]]), and this is fine
with me. It can be customised away, though.

Aside from Brendan's suggestion (which I should have thought of
myself!), all the information for the above came from chapter 4
(Hyperlinks) from the org-mode manual (http://orgmode.org/org.pdf).
