Tony, I am attempting to get HA running on our existing sipX clustered system. What we have now is a single Bridge to our ITSP, and 2 backend HA-enabled SIPX Servers, 1 of which is a Redundant SIP Router, the other Primary.
The idea being that using DNS (as posted in various places) and SRV records, we can direct SIP traffic to the primary server, and if the primary goes 'down' the redundant will then be used - assuming DNS is set up properly (using DNS priorities and weights). Per my earlier emails, our DNS matches exactly what DNS Advisor says it should look like. The problem I have, is that calls coming in from our ITSP hit our SIP Bridge, and are then routed to our Redundant SIP Router. Again, I showed this in earlier emails, through the use of SIP Viewer. If I understand, provided the DNS SRV records are set up correctly, that should not happen. Calls should go to our Primary SIP Router. Instead, inbound calls are coming from our ITSP, hitting our SBC, and are being directed to SIPX2 (Redundant). The call then fails to work. That leads me to two questions: 1. Why are the calls being directed to SIPX2 in the first place, if DNS is set up correctly? 2. Why would the Redundant SIP Router not work? That above the summation of my original question. To reply to your questions and comments below: Are you saying that every server in a sipX environment needs to have SIP Proxy running on it? That service is part of the SIP Router role. SO even on a SIP Trunking server (a standalone role), I need to have it set up as a redundant sipx router as well? Let me try to better explain our environment as it stands now. If I have something that will not work, please let me know. We have one server running the SIP Trunking role, that acts as our internal SBC to our current ITSP. This is a server named SBC1. Behind our firewall, is our two HA-enabled SIPX servers. The server SIPX1 is running all Roles, EXCEPT SIP Trunking. The server SIPX2 is running the Redundant SIP Router Role only, as an HA Backup should SIPX1 go down. DNS SRV records are set up correctly, according to the DNS Advisor. Yet calls act as described above in this setup. If I remove the DNS SIP SRV records (TCP and UDP) for the SIPX2 server, everything works as expected.

I don't recall what you are trying to do (one server with role of sipxbridge only) was a design intent (or supportable).

If so that IS the case - on both SIPX1 and SIPX2 the SIP Proxy service (part of the SIP Router role, both Primary and Redundant) is in fact running. In response to Dave - UDP records had the same settings as TCP except Weight (as both servers are set zero weight) which makes no difference: ; <<>> DiG 9.3.4-P1 <<>> -t SRV _sip._udp.our.domain.net ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 39721 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 2 ;; QUESTION SECTION: ;_sip._udp.our.domain.net.
