So, I'm the new network guy at our employer and I've walked in on a VoIP project that has been going on for almost 2 years (people keep quitting) and the vendor is getting stressed with us, naturally. I have configured ports for VoIP, but I have never done a full blown rollout for new phones. The vendor asked me to get Option 150 set up on our end and I'll be honest, I had to look that up. Now I understand what Option 150 is, I'm having a terrible time finding straight out documentation or even just a video explaining where I need to configure at. From what I'm thinking, I'm thinking I need to configure it on our tftp-server, but then do I need to configure per VLAN and on every switch in our network too?
