[cisco-voip] CUPS SIP Proxy Redundancy

[Paul Dillon]

Kevin,

I am still confused here after reading the PDFs:

In Active Dir DNS:

I need to add 2 DNS SRV entries to the DNS: of the same name but with
diifferent weights and priorities. Is the port number 5060 and what do you
use for UDP for protocol and what do you use for Service? Is the host the IP
address of the SIP Proxy

Then on CVP Call Server disable outbound proxy and use DNS SVR and create a
static route > to the DNS SRV

Do I change the SIP-UA SIP Server to the DNS SRV address hence requiring DNS
on gateways

Similarily on the Call managers do I use the same DNS name in the SIP Trunk
instead of the SIP Proxy IP address and also requiring DNS on CCM. Or do I
add a second SIP trunk for the secondary Proxy

Thanks

Paul
