Just a little follow-up to my Grandstream experiment. I like this system. Through the magic of Voipsupply.com and eBay, I now own THREE phones on my system and I picked up a 4-port box for analog cameras(GXP-3504). Tech support gave me the instructions to interface my Yealink T-28 phone to the UCM and I'm playing with the features. Kinda sneaky, but there is a blacklist feature that plays SIT tones and a disconnect message. I haven't played with the wildcard commands, but it could be that the wily telemarketer that uses a fake CID can be blanket blocked by area code and/or exchange.
