Hi!
i've just got a Cisco 7821-3PCC Phone, and successfully registered it to my SIP server. The phone is reachable and calls from my old Cisco phones to the new one works just fine. If i try to call my phones using the new one, but the phone just says "invalid number".
To call internal numbers, i'have to dial ** first. For example **621. I think the phone ignores that "Star Code"
is there an option i have to enable?
