i have a mistake with mu outbound calls, i have a SBC multitenant and i configure a tenant inbound calls are ok but outbound calls not ok.

I have this message:Unable to deliver INVITE: No connection could be made because the target machine actively refused it SBC AUDIOCODES IP:5067,TENANT FQDN,No,""

I've seen this when the SBC isn't listening on port 5067. Common port for sip over TLS is 5061. Double check your SBC settings, or confirm with your vendor.
