Multiple SBCs for Direct Routing
Hi Guys, If I have two SBCs connected to Teams for Direct Routing, do I need to use a different SIP Port number for each connection? I would not have thought so but I am having some connection is...
GerryArmstrong If you have two SBCs (i.e.: us-sbc1.contoso.com and us-sbc2.contoso.com), each SBC can be referenced by the the same SIP port (5061, for instance). The port is a child object that is always paired/matched with the SBC FQDN, so there's no restriction on being able to use port 5061 with one, or potentially hundreds, of SBCs. If you've got an SBC showing offline, items you may want to check:
- NTP server configured on SBC
- DNS configured on SBC
- Proper TLS certificate
- TLS certificate trust (root cert)
- SBC NAT (if applicable)
- SBC IP Routing
- Ingress/Egress Firewall rules for SBC
- Thanks Trevor, that is what I was expecting to hear.
