I have (2) cubes routers at different locations. (1) in DC and the other in Dallas, they both have SIP trunk connected to them via CUCM 10.5. Fail-over from our DC location to Dallas works fine. The RTP traverse through the WAN as normal. Dallas fail-over does not work, I can receive in bound calls but get a fast busy when trying to get out.
I do the calls hitting the Dallas cube but they just stay there. The cube routers have a DS3 Connection into Verizon.
Please help
