Information in this document applies to any platform.
VNF OCSBC: nnSCZ830p3
Os: Windows Server 2019 Standard, Version 1809
Hypervisor: Microsoft Hyper-v
Set the VM adapters in trunk mode.
Installed 8.3.0.p3 in HA configuration. Initially configured HA-only to get that up and running. Subsequently configured an access-realm for phones and a core-realm with a proxy. The goal is to get a phone registered. The phone doesn't get a response to a REGISTER. packet-trace local start on the sbc does NOT show the REGISTER coming in. To rule out incorrect routing I installed sipsak on the same subnet as the sip-interface subnet and repeated the test with an OPTION ping NOT seeing it in the packet-trace local start. Then I enabled OPTIONS ping on the proxy with a packet-tr running. This showed OPTIONS destined to the proxy but remain unanswered/no response. The proxy did NOT receive the OPTIONS.
