Name Service Protocol Priority Weight Port Target host
internal-domain.net. h323cs tcp 10 10 1720 vcsc.internal-domain.net.
internal-domain.net. h323ls udp 10 10 1719 vcsc.internal-domain.net.
internal-domain.net. h323rs udp 10 10 1719 vcsc.internal-domain.net.
internal-domain.net. sip tcp 10 10 5060 vcsc.internal-domain.net.
internal-domain.net. sip udp * 10 10 5060 vcsc.internal-domain.net.
internal-domain.net. sips tcp 10 10 5061 vcsc.internal-domain.net.
* SIPUDP is disabled on VCS by default.
For example, the DNS records would be:
_h323cs._tcp.internal-domain.net. 86400 IN SRV 10 10 1720 vcsc.internal-domain.net.
_h323ls._udp.internal-domain.net. 86400 IN SRV 10 10 1719 vcsc.internal-domain.net.
_h323rs._udp.internal-domain.net. 86400 IN SRV 10 10 1719 vcsc.internal-domain.net.
_sip._tcp.internal-domain.net. 86400 IN SRV 10 10 5060 vcsc.internal-domain.net.
_sip._udp.internal-domain.net. 86400 IN SRV 10 10 5060 vcsc.internal-domain.net.
_sips._tcp.internal-domain.net. 86400 IN SRV 10 10 5061 vcsc.internal-domain.net.
vcsc.internal-domain.net. 86400 IN A 10.0.0.2
If you have a cluster of VCS Controls, you must set up DNSAand SRV records for each peer/host in the cluster. See
VCS Cluster Creation and Maintenance Deployment Guide for more information.
