Thanks for the input. I like the Shoretel solution also. Has anyone looked at Sphere? If so what do you think of this solution?

I am of the opinion that Cisco offers the best future. They are more expensive, in some cases significantly, in my case they have pretty much matched the Shoretel pricing. The problem is the integration with the desktop is clunky. The features,(like read back Voice Mail and applications to the phone ), are not a big deal at this point for us. I also don't like how they store Voice Mails in yourt EMail account. THis creates storage issues. In the end they are investing more than most, have a great reputation and the money to stay in the game for a long time.
