I have multiple PBXs that all need to have SIP Trunking enabled in order to get the best Return on Investment (ROI).
I would like to centralize all of my SIP Trunking in a single location.
SIP Trunking is complex new technology, how do I make Trouble shooting easier.
How can I ensure that I am compliant with my companys security policies when I implement SIP Trunking ?
Challenge Impact of an SBC
Allows you to have a single interconnect point to your Service Provider across multiple disparate systems.
Allows you to scale your SIP Trunk solution while only connecting to one device.
Allows a single point of troubleshooting for your SIP Trunks. A device that is supported by Cisco allows you to have one vendor support your entire solution.
SBCs ensures security on SIP Trunks. An SBC from a trusted vendor such as Cisco incorporates security in all aspects from an embedded firewall to administrative control on changes.

Each site has direct connection
for SIP sessions to SP
Takes advantage of SP session
pooling, if offered by SP
Media traffic goes direct from
each branch site to the SP
Leverages existing branch
routers
No media hair-pinning thru any
site.

Characteristics of Hybrid Benefits
Connection to SP SIP service is determined on a site
by site basis to be either direct or routed through a
regional site.
Decision to route call direct or indirect based on
various criteria
Media traffic goes direct from site to SP or hairpins
through another site, depending on branch
configuration.
