i am designing a network for a company and the question has come up about IP telephony. From the requirements ive gotten so far is about 50-70 total phone lines would be needed. I handle data and system services and this would be my first VoIP install. I want to stick with Cisco if possible, i dont need a lot of features. What are some good suggestions and what are some good websites for references on how to implement these kind of solutions. Any advice would be greatly appreciated.
