So we are moving to VOIP in our Denver office. This will be a new area for us as we are a long time Siemen's PBX customer. After much consideration we've decided to go with ShoreTel
The decision was based on price, performance and ease of use. Once again Cisco lost out on two of those issues...price and ease of use. The performance metric was difficult to get a handle on (I'm not sure I ever did) because you'd almost have to do a bake off to tell the difference. In the end, ease of use was the real motivation to go with ShoreTel. We don't have a full time telcom person so I need my network admins to be able to configure and support the gear. Cisco once again is just too complicated to deal with. I'll let you know how it goes but so far I'm really excited.
Note to my open source homies: I did think about SwitchVox and given more time I may have decided to go with them. However, in the interest of time (we go live 01/01/2009) and given the fact that there will be no IT support people in our Denver office I wanted a known, tested system. So basically I whimped out. Sometimes you gotta pick you battles.
