I have a problem where I can't make any external calls roughly after 9-10pm at night and not on weekends. I've checked all the extension settings, they are all set to use global office hours and the box to block outbound calls outside of office hours is UNTICKED. When making a call I get a message saying the mobile number has been disconnected even though I received a call from that number 2 mins prior. How do I view the global office hours setting, I cant find it. I'm using phone system version 14 with service packs 1, 2 & 3 up to date. Any help or suggestions will be greatly appreciated!
