MediaPack SIP User’s Manual 5. Configuring the MediaPack
Version 4.6 57 June 2005
Table 5-2: Proxy & Registration Parameters (continues on pages 57 to 60)
Parameter Description
Enable Proxy
[IsProxyUsed]
Don’t Use Proxy [0] = Proxy isn’t used, the internal routing table is used instead
(default).
Use Proxy [1] = Proxy is used.
If you are using a Proxy server, enter the IP address of the primary Proxy server in the
Proxy IP address field.
If you are not using a Proxy server, you must configure the Tel to IP Routing table on the
gateway (described in Section
5.5.4.2 on page 83).
Proxy Name
[ProxyName]
Defines the Home Proxy Domain Name.
If specified, the Proxy Name is used as Request-URI in REGISTER, INVITE and other SIP
messages. If not specified, the Proxy IP address is used instead.
Proxy IP Address
[ProxyIP]
IP address (and optionally port number) of the primary Proxy server you are using.
Enter the IP address as FQDN or in dotted format notation (for example 201.10.8.1).
You can also specify the sele
cted port in the format: <IP Address>:<port>.
This parameter is applicable only if you select ‘Yes’ in the ‘Is Proxy Used’ field.
If you enable Proxy Redundancy (by setting EnableProxyKeepAlive=1), the gateway can
work with up to three Proxy servers. If there is no response from the primary Proxy, the
gateway tries to communicate with the redundant Proxies. When a redundant Proxy is
found, the gateway either continues working with it until the next failure occurs or reverts
to the primary Proxy (refer to the ‘Redundancy Mode’ parameter). If none of the Proxy
servers respond, the gateway goes over the list again.
The gateway also provides real time switching (hotswap mode), between the primary and
redundant proxies (‘IsProxyHotSwap=1’). If the first Proxy doesn’t respond to INVITE
message, the same INVITE message is immediately sent to the second Proxy.
Note 1: If ‘EnableProxyKeepAlive=1’, the gateway monitors the connection with the
Proxies by using keep-alive messages (OPTIONS).
Note 2: To use Proxy Redundancy, you must specify one or more redundant Proxies
using multiple ’ProxyIP= <IP address>’ definitions.
Note 3: When port number is specified (e.g., domain.com:5080), DNS SRV queries aren’t
performed, even if ‘EnableProxySRVQuery’ is set to 1.
Gateway Name
[SIPGatewayName]
Use this parameter to assign a name to the device (For example: ‘gateway1.com’). Ensure
that the name you choose is the one that the Proxy is configured with to identify your
media gateway.
Note: If specified, the gateway Name is used as the host part of the SIP URL, in both ‘To’
and ‘From’ headers. If not specified, the gateway IP address is used instead (default).
Gateway Registration Name
[GWRegistrationName]
Defines the user name that is used in From and To headers of REGISTER messages.
Applicable only to single registration per gateway (’AuthenticationMode = 1).
If ‘GWRegistrationName’ isn’t specified (default), the ’Username’ parameter is used
instead.
Note: If ‘AuthenticationMode=0’, all the gateway’s endpoints are registered with a user
name that equals to the endpoint’s phone number.
First Redundant Proxy IP
Address
[ProxyIP]
IP addresses of the first redundant Proxy you are using.
Enter the IP address as FQDN or in dotted format notation (for example 192.10.1.255).
You can also specify the sele
cted port in the format: <IP Address>:<port>.
Note 1: This parameter is available only if you select ‘Yes’ in the ‘Enable Proxy’ field.
Note 2: When port number is specified, DNS SRV queries aren’t performed, even if
‘EnableProxySRVQuery’ is set to 1.
ini file note: The IP address of the first redundant Proxy is defined by the second
repetition of the ini file parameter ‘ProxyIP’.
Second Redundant Proxy
IP Address
[ProxyIP]
IP addresses of the second redundant Proxy you are using.
Enter the IP address as FQDN or in dotted format notation (for example 192.10.1.255).
You can also specify the sele
cted port in the format: <IP Address>:<port>.
Note 1: This parameter is available only if you select ‘Yes’ in the ‘Enable Proxy’ field.
Note 2: When port number is specified, DNS SRV queries aren’t performed, even if
‘EnableProxySRVQuery’ is set to 1.
ini file note: The IP address of the second redundant Proxy is defined by the third
repetition of the ini file parameter ‘ProxyIP’.
