[VoiceOps] Shoretel/Mitel phone systems and generic SIP trunking

Shoretel is a sleazy, horrible organization that always seeks to extract
maximum cash from their vict(COUGH) customers.  I've only had two customers
with Shoretel systems, and in both cases we eventually got it to work after
they paid Shoretel for "SIP licenses" (SRSLY?!?) and paid their techs for
interop/setup.  However at that time (last one was a few years ago), they
didn't insist we needed to get any certifications or anything.  We just
explained that we were running fully generic SIP on our end and all we
needed was an RFC compliant call hitting us.  My only suggestion is to get
the customers to insist on this support from Shoretel.  I'm guessing they
get a kickback from their "approved" vendors.
