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

[Brandon Buckner]

It’s been a few years since I managed any ShoreTel systems, but we provided SIP trucks via Metaswitch business groups and a fairly generic config. The biggest pain was as Carlos alluded to: you have to pay a license for anything over 1 or 2 concurrent SIP sessions for trunking. Once you had that it was very easy and worked well.

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.
