I have 4 sets of cube routers running HA. Three are fine but the last set I am getting 503 errors only if I use the virtual interface and on inbound calls only.. If I use the physical interface all works fine. Code level is 16.9.4 of CUBE router they are ISR 4331's , CUCM is 11.5. All the configurations look the same . If I use the virtual address the SIP trunk does come up and outbound calls seem to work fine. The
Anyone seen this kind of behaviour.
