I'd tag it as what it is, building=telephone_exchange. That would
be suitable with or without windows. <br>
<br>
I have added a section on them to
<a class="moz-txt-link-freetext" href="https://wiki.openstreetmap.org/wiki/Talk:WikiProject_Telecoms#Telephone_Exchange">https://wiki.openstreetmap.org/wiki/Talk:WikiProject_Telecoms#Telephone_Exchange</a><br>

You can attempt to contact the original mapper .. they may well
point to the OSM wiki telecoms page, that looks to be the source
of it. <br>

Hi,
<div>The telecom tagging scheme (on wiki) definitely had a tag for
telephone exchanges. </div>
<div>For a building without windows, I’d suggest building=service<br>

28014 Madrid that contains a phone exchange
(originally it was a gigantic relay system for the
phones of the area, now probably replaced with
smaller computers and microcontrollers). </div>
<div>It is tagged as "building=central office", a
non-standard tag.</div>
<div>I wonder if tagging it as "building=industrial"
would be better, despite of the whole neigbourhood
being officially classified as "tertiary use"
(non-industrial). </div>

</div>
<div>Or maybe "building=yes" would be just enough.

Delicias, Madrid, enough old to be announced as
"phone booths that way" on the street. It is tagged
as "building=yes".</div>
