SIP
The
SIP
page allows you to enable and disable SIP on the VCS,
and configure SIP-specific ports and settings.
To go to the SIP page:
VCS configuration > Protocols > SIP > Configuration
•
To configure SIP using the CLI:
xConfiguration SI
•
P
Enabling SIP
SIP support is
On
by default.
To enable and disable SIP functionality (i.e. SIP Registrar and SIP
proxy services) on the VCS, use the
SIP mode
setting.
SIP registration expiry
SIP endpoints must periodically re-register with the SIP Registrar
in order to prevent their registration expiring. You can configure
the interval with which SIP endpoints must register with the VCS
by using the
Registration expire delta
setting.
The default is
60
.
The
Registration expire delta
setting applies only when
the VCS is acting as a SIP Registrar, and to endpoints
registered with the VCS. It does not apply to endpoints
whose registrations are being proxied through the VCS.
SIP registration proxy mode
This setting specifies how proxied registrations and invites will be
handled.
Off
: Registration requests will not be proxied (but will still be
permitted locally if the VCS is authoritative for that domain).
Invite requests with existing Route Sets will be rejected.
Proxy to known only
: Registration requests will be proxied, and
invite requests will be proxied only if the Route Set contains
the URI(s) of neighbors (including traversal clients and traversal
servers).
Proxy to any
: Registration requests and invite requests will
always be proxied.
The default is
Off
.
SIP protocols and ports
The VCS supports SIP over UDP, TCP and TLS transport
protocols.
You can configure whether or not incoming calls using each
protocol are supported, and if so, the ports on which the VCS
will listen for such calls. This is done using the
Mode
and
Port
settings for each protocol.
The default
Mode
for each protocol is
On
, and the default ports
are:
UDP port
•
:
5060
TCP port
•
:
5060
TLS port
•
:
5061.
At least one of the UDP, TCP or TLS transport protocols
must be set to a
Mode
of
On
in order for SIP functionality
to be supported.
You can also specify the range of ports the VCS will use once
calls are established using the
TCP Outbound Port Start
and
TCP
Outbound Port End
settings.
The default range is
25000
to
29999
.
This range must be sufficient to support all required
concurrent calls.
Configuring SIP
The
Domains
page lists the SIP domains for which the VCS
is authoritative, and allows you to add, edit and delete SIP
domains.
To go to the
Domains
page:
VCS configuration > Protocols >SIP > Domains
•
.
To configure SIP domains using the CLI:
xCommand DomainAd
•
d
xCommand DomainDelet
•
e
xConfiguration SIP Domain
•
s
The VCS will act as a SIP Registrar and Presence Server for all
these domains, and will accept registration requests for any SIP
endpoints attempting to register with an alias that includes any
of these domains.
