Why does this happen? There's a device name limit within PHONE, and specifically within some device name parsing code. That's what this thread discusses.
Why does this happen? Because most folks aren't using PHONE, and nobody noticed the device name parsing error during the typical tests? (That this incompatibility has been around as it has been -- the device name change was a while ago -- certainly points to few folks using PHONE.)
Why does this happen? Because all businesses have resource limits and software development bandwidth limits, and businesses must prioritize what they can do with their software, and where they can recoup those investments. Ask HP to open-source PHONE, and somebody out here will fix it. Or move to Jabber or irc or such; to protocols and clients that are seeing more active development than PHONE is clearly receiving.
