their properties.
When PathNavigator is used, this prefix automatically
registers with the gatekeeper. When another
gatekeeper is used, this prefix must also be defined in
the gatekeeper.
SIP Select this check box to indicate that SIP participants
can connect to the MCU using this service. Then select:
• Specify - to manually define the SIP server.
• Auto - to automatically detect the SIP server’s IP
address if a DHCP or if a DNS Server is defined.
SIP Server IP
Address or
Name If SIP-Specify is selected, and a DHCP is not used,
enter either the IP address of the preferred SIP server
or its host name (if a DNS server is used).
Domain Name
or IP Address Conferences and Entry Queues can be registered in the
proxy in the format user@host. for example,
[email protected], where EQ1is the user part and
polycom.com is the host part.
When dialing to a conference or Entry Queue, the SIP
server expects to receive the host either as domain
name or as an IP address.
The domain name is used for identifying the SIP server
in the appropriate domain according to the host part in
the dialed string. For example, when the call to
[email protected] reaches the outbound proxy, this
proxy looks for the SIP server in the polycom.com
domain to which it will forward the call.
When this call arrives at the SIP server in polycom.com,
the server looks for the registered user (EQ1) and
forwards the call to this Entry Queue or conference.
