SIP Information
Destination Address The Destination Address represents the remote SIP peer with which
this trunk will communicate. The allowed values for this field
specify a valid V4 dotted IP address, fully qualified domain name
(FQDN), or DNS SRV record only if the Destination Address is an
SRV field is checked.
Tip For SIP trunks that can support IPv6 or IPv6 and IPv4
(dual-stack mode), configure the Destination Address IPv6
field in addition to the Destination Address field.
Note SIP trunks only accept incoming requests from the
configured Destination Address and the specified incoming
port that is specified in the SIP Trunk Security Profile that
is associated with this trunk.
Note For configuring SIP trunks when you have multiple device
pools in a cluster, you must configure a destination address
that is a DNS SRV destination port. Enter the name of a
DNS SRV port for the Destination Address and check the
Destination Address is an SRV Destination Port check
box.
If the remote end is a Cisco Unified Communications Manager
cluster, DNS SRV represents the recommended choice for this field.
The DNS SRV record should include all Cisco Unified
Communications Managers within the cluster.
