Charles, My issue I believe is related to Verizon provisioning.  So we have two cubes, one in each data center with SIP trunks to Verizon respectively. Data center 1 Cube 1 x.x.x.101 Vzb provisioned to port 5075  Data center 2 Cube 2 x.x.x.102 Vzb provisioned to port 5076 Scenario 1: Call goes out Cube 1 (primary for DN per Vzb) matching the port 5075 and call is good. Scenario 2: Force call to go Cube 2 using css with RL to Cube 2 and call fails using port 5076.  Vzb says DN is provisioned to use 5075 and can we send port 5075. How can we accomplish this or should the port for each SRV be the same from a Verizon provisioning?  We have 6000 numbers and I don't see how we can configure all these number to use different ports.  Adding dial-peers for each number does not scale. Hopefully I explained this to make sense.  Any help is much appreciated.     ... View more

Sasikumar, I tagged this short explaination while studying......Prior to ICM 7.1, you could use a Type 2 to support warm transfers which were a quasi translation route with separate Type 2 CVP servers. With ICM 7.1 and later, a Type 10 can be used for warm transfers and ingress switch/vru leg. Also as jpsweeney77 mentioned the SRND for CVP has much more detail. ... View more
