I have a very simple setup of an Linksys SPA9000 and SPA400 with a couple of Cicso SPA5xx phones and a couple of softphones. I'm using a PSTN line for all incoming and outgoing calls but I want to take advantage of the features a IP telephony system provides. I've set it up to receive and make incoming, outgoing and internal calls but I need help with the caller ID and the voicemail system.
