Field Description
SIP Specifies how proxied registrations and requests
registration containing Route Sets are handled.
proxy mode
Off: registration requests are not proxied (but are
still permitted locally if the VCS is authoritative for
that domain). Requests with existing Route Sets
are rejected.
Proxy to known only: registration requests are
proxied in accordance with existing call processing
rules, but only to known neighbor, traversal client
and traversal server zones. Requests containing
Route Sets are proxied only if they were received
from a known zone.
Proxy to any: registration requests are proxied in
accordance with existing call processing rules to all
known zones. Requests containing Route Sets are
always proxied.
Default is Off.
SIP The VCS supports SIP over UDP, TCP and TLS
protocols transport protocols. You can configure whether or
and ports not incoming and outgoing connections using each
protocol are supported, and if so, the ports on which
the VCS listens for such connections.
This is done using the Mode and Port settings for
each protocol. The default mode for each protocol
is On; the default ports are:
UDP port: 5060
n
TCP port: 5060
n
TLS port: 5061
n
TCP The range of ports the VCS uses when TCP and
outbound TLS connections are established. The default range
port start / is 25000 to 29999.
end
Session The maximum time allowed between session
refresh refresh requests for SIP calls. Default is 1800.

protocols must be set to a
Mode of On for SIP

The range must be sufficient to
support all required concurrent
connections.
