VCS port reference
Service/function Description
DNS Used for sending requests to DNS servers.
H.225 and H.245 call The range of ports to be used for call signalling
signaling port range once a call is established.
SIP TCP outbound port The range of ports to be used by outbound TCP/
range TLS SIP connections to a remote SIP device.
Traversal media port range For traversal calls (i.e. where the VCS is taking
the media as well as the signaling), the range
of ports to be used for the media. Ports are
allocated from this range in pairs, the first of
each being even. Therefore the range must
start with an even number. See
Traversal Subzone ports
STUN relay media port The range of ports to be used for STUN media
range relay.
LDAP Used for outbound connection to an LDAP server
(if the VCS is configured to use an LDAP server
for H.350 authentication).
External manager Used for outbound connection to an external
manager e.g. TMS.
User Policy server Used for outbound connection to a User Policy
