Over the last few weeks, I've spent quite a bit of time talking with a variety of partners about leveraging SIP in large enterprise deployments and specifically the architectures used to support branch offices. When I first starting working on this problem, my original reaction was "Simple, just put in a softswitch and connect all the sites together via SIP - Done".
It turns out it's not that easy. From listening to our partners and their customers, I have learned there are a few real challenges they deal with when deploying communications systems into distributed branch office situations:
First you need to get good quality broadband to every one of your branch offices, which is hard to do once you leave the urban/suburban rings of most cities. Getting voice-grade broadband to remote offices in rural America can be very expensive and wipe out any potential cost savings. Consumer grade broadband is easier to get, but even then not predictable enough for commercial applications.
Second is the question of reliability, which was recently demonstrated by the massive Internet outage in San Jose. What will happen to your business if the broadband connection to the site is cut? Do you just close for the day and kiss off the revenue?
Third is network traffic optimization - does every call really need tie up your broadband service? Is there a more efficient way to leverage the expensive and shared broadband that services the branch offices?
The solutions seems to be in an architecture that fits somewhere between the two extremes of fully centralized and fully distributed, but exactly where depends on the individual business.
To discuss these challenges and some potential solutions, I've invited Bruce Mazza, Director of Branch Office Solutions for Avaya to join me in a live webinar on Tuesday, April 14th at 2 PM.
