<p class="MsoNormal">Has anyone deployed SBCs at 2 or more location with the design
requirement to be Highly Available and preserve calls during a failure?
Customer has 2 Cubes and will have 2 Verizon SIP trunks at 2 different
geographical locations. Provider will use round-robin for call setup and we can
similar from the CM/CUBE side. What is in question is call preservation if one
cube fails. It has been recommended to use media-flow around but not sure that
will give us the call preservation in a failure. What is the recommended design for this. CUBE HA appears to be limited to same segment installs and HSRP is not going to work at diverse locations for a carrier.</p></div>
