Thanks alot for your quick replies, I didn't have double <> for To and From in my question if you check the first thread again. :) Want to add one more thing, Just to cross check, when I sent a NOTIFY packet from Asterisk to extension directly, it works showing me blinking red light on the phone!. And I can configure MWI on Grandstream phone. Please have some more thoughts, Thanks, --SM
