<%= "setvar = extphonemask=#{@l.external_num}\n" if @l.external_num -%>


### OUTPUT ###
# output with maddening blank lines for nil values. Want nil lines to be ignored, so no newlines.
# I have tried to suppress with both ERB and Erubis. I read Erubis is supposed to support my desired
# behavior by default. Not working. I've tried using ERB instantiating with ERB.new(var, nil, '-') and
# using <%- ruby_stuff -%> and it's not working as expected either.
