Description
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 present and
defined.
If SIP – Specify was selected, enter either the IP
address of the preferred SIP server or its host name (if a
DNS server is used)
Conferences and Entry Queues can be registered in the
proxy in the format user@host. for example,
EQ1@polycom.com.
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
EQ1@polycom.com reaches its 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 to the SIP server in polycom.com,
the server looks for the registered user (EQ1) and
forwards the call to this Entry Queue or conference.
