Often, the first consideration for implementing a converged voice, data and video network using Internet Protocol (IP) technology is its ability to help contain operational costs and deliver significant savings through toll bypass. However, from a strategic perspective, IP telephony and its underlying converged network can act as an enabling technology, facilitating more responsive customer relations through next-generation contact centers and making employees more productive with applications like collaborative computing. The advantages of convergence are truly open-ended and the boundaries around the ways that progressive organizations exploit IP technology continue to be pushed.

This is a great paper that dives into the firewall/NAT traversal issue. The paper provides solid alternatives and solutions to the problem so that Session Initiation Protocol (SIP) sessions can be supported throughout an enterprise. For background on the firewall/NAT traversal issue: SIP-based communication does not reach users on a LAN behind firewalls and Network Address Translation (NAT) routers automatically. Firewalls are designed to prevent inbound unknown communications and NAT stops users on a LAN from being addressed. Firewalls are almost always combined with NAT and typically do not support SIP properly.
