I just got a call from a auto glass dealership with 4 stores. He wants to upgrade his 4 r3's to either 6 or 7. He wants to be able to call forward his remote locations to his main branch after hours. And the phone company CF feature is a pain in the butt.

Is it better to use the upgrade cards or just throw in r6's or r7's.

Thankx Mitch

Mitch,If his current systems are working fine then I would just do the upgrades to 6, If he wants to replace them stay away from the R7 until they get the bugs out as they are having allot of failures on them, the R6 is solid.
