SIP, Session Management and Beyond
SIP, Session Management and Beyond…What does it all MEAN?
Earlier this year, AT&T published a letter to the FCC in which they stated:
“Due to technological advances, changes in consumer preference and market forces, the question is when, not if, POTS service and the PSTN over which it is provided will become obsolete.”
Segment 1: The Opportunity for Transformation
Segment 2: Fundamentals of SIP
I LOVE this animation. Fun and educational. Seriously – hat’s off to the team for this one.
Segment 3: SIP Trunking with CUBE (Cisco Unified Border Element)
Segment 4: Session Management and Legacy PBX Integration
Wade Hamblin is back and joins Jimmy Ray in the lab to dig into this whole “session management” business. As Jimmy Ray puts it, this is where “the butter meets the popcorn”.
The job of Session Management Edition (SME) is to sit in the middle of your network and bring together different protocols and systems. A perfect example of customer situation where this is helpful: acquisitions – how to you bring different systems together when your company acquires other companies? Jimmy Ray calls it out right away – that is nice, but don’t I have to upgrade my legacy PBX to do this? Nope. Session Management supports multiple protocols allows you to route between different communications systems and applications.
Watch as Wade takes Jimmy Ray by surprise with his declaration that with Intercompany Media Engine (IME) will work with your legacy PBX systems. What?! Don’t you need IP Phones to make that work? Nope! Want to see some IME calls in action? This video captures our SVP, Tony Bates, as he calls up some customers around the world and leverages the power of IME.
Service Advertisement Framework (SAF) allows you to advertise and discover the capabilities in the network. For example, a Communication Manager may “own” the 415 area code and advertise this – allowing all systems in the network to know to route all calls to 415 numbers to that system. Furthermore, this allows the network to be more resilient for automatic reconfiguring of routes.
Segment 5: Session Management and Unified Border Element
Wade is still trapped in the lab with Jimmy Ray and they begin to dig into the how native SIP built into Communications Manager since CM 5.0. This gives us the ability to normalize SIP messages centrally and customize how things are handled. Many service providers want to offer Early Offer – which is often a pain to manage and troubleshoot. In an upcoming release, we’ll be the ability to support native early offer. (Jimmy Ray cheers with joy!).
Some other benefits that pop up: centralized accounting and centralized troubleshooting. With centralized troubleshooting, we use the SIP ladder diagram to simplify the troubleshooting and provide a clear visual representation of what is going on with that call. Want to learn more about SIP ladder diagram? Join me and Wade on May 19th for a deep-dive workshop on this handy tool!
Finally, media manipulation on CUBE – Wade describes a scenario were the ability to clean out background noise and white noise would have been handy. (Ever tried your softphone from an airplane? It works, but everyone can hear all the noise around you!). Features in CUBE will screen out these kind of background noises. (This is not VAD!) Wade throws out one more teaser for the May 19th workshop: redundancy and resiliency in CUBE.
Boldly go into the future! Decisions are being made around you and no decision is a decision in of itself. You can leverage your existing investments and still bring new features into your communications infrastructure.
