By default, bbdb-dial-number will pass phone numbers to browse-url
using the tel URI.  The actions taken by browse-url are determined
by browse-url-browser-function.  In most cases, the latter variable
is probably the one to use (and not bbdb-dial-function, unless
different emacs packages should handle phone numbers differently).
In that sense the question is not about BBDB in particular.

But in the end, coming from emacs, the question remains what to use
for browse-url-browser-function.  I do not know anything about that.
