Where 5222 fits
Why 5222 is special
XMPP was the backbone of Google Talk and Facebook Chat before both withdrew from it, and it remains what WhatsApp was originally built on. It is the standard example of federated messaging losing to closed networks despite being technically adequate.

5 × 1,000 + 2 × 100 + 2 × 10 + 2 × 1 = 5,222. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Related numbers & connections
SIP sets up voice calls and XMPP carries messages, and both are open federated protocols that were widely adopted and then largely displaced by closed platforms.

XMPP is an open, federated messaging standard that Google Talk and Facebook Chat both used and both abandoned, and that WhatsApp was originally built on. It is the standard case study in a technically adequate open protocol losing to closed networks for reasons that were not technical.
