MP-1xx SIP User’s Manual 5. Configuring the MP-1xx
Version 4.4 51 March 2005
Table 5-2: Proxy & Registration Parameters (continues on pages 49 to 52)
Parameter Description
Re-registration Timing (%)
[RegistrationTimeDivider]
Defines the re-registration timing (in percentage). The timing is a percentage of the re-
register timing set by the Registration server.
The valid range is 50 to 100. The default value is 50.
For example: If ‘RegistrationTimeDivider = 70’ (%) and Registration Expires time = 3600,
the gateway resends its registration request after 3600 x 70% = 2520 sec.
Registration Retry Time
[RegistrationRetryTime]
Defines the time period (in seconds) after which a Registration request is resent if
registration fails with 4xx, or there is no response from the Proxy/Registrar.
The default is 30 seconds. The range is 10 to 3600.
Enable Proxy Keep Alive
[EnableProxyKeepAlive]
No [0] = Disable (default).
Yes [1] = Keep alive with Proxy is enabled.
If enabled, ‘OPTIONS’ SIP message is sent every ‘Proxy Keep-Alive Time’.
Note: This parameter must be enabled when Proxy redundancy is used.
Proxy Keep Alive Time
[ProxyKeepAliveTime]
Defines the Proxy keep-alive time interval (in seconds) between OPTIONS messages.
The default value is 60 seconds.
Use Gateway Name for
OPTIONS
[UseGatewayNameForOpt
ions]
No [0] = Use the gateway’s IP address in keep-alive OPTIONS messages (default).
Yes [1] = Use ‘GatewayName’ in keep-alive OPTIONS messages.
The OPTIONS Request-URI host part contains either the gateway’s IP address or a string
defined by the parameter ‘Gatewayname’.
The gateway uses the OPTIONS request as a keep-alive message to its primary and
redundant Proxies.
Enable Fallback to Routing
Table
[IsFallbackUsed]
No [0] = Gateway fallback is not used (default).
Yes [1] = Internal Tel to IP Routing table is used when Proxy servers are not available.
When the gateway falls back to the internal Tel to IP Routing table, the gateway continues
scanning for a Proxy. When the gateway finds an active Proxy, it switches from internal
routing back to Proxy routing.
Note: To enable the redundant Proxies mechanism set ‘EnableProxyKeepAlive’ to 1.
PreferRouteTable
[Prefer Routing Table]
Determines if the local Tel to IP routing table takes precedence over a Proxy for routing
calls.
No [0] = Only Proxy is used to route calls (default).
Yes [1] = The Proxy checks the 'Destination IP Address' field in the 'Tel to IP Routing'
table for a match with the outgoing call. Only if a match is not found, a Proxy is used.
Note: Applicable only if Proxy is not always used (‘AlwaysSendToProxy’ = 0,
‘SendInviteToProxy’ = 0).
Use Routing Table for Host
Names and Profiles
[AlwaysUseRouteTable]
Use the internal Tel to IP routing table to obtain the URL Host name and (optionally) an IP
profile (per call), even if Proxy server is used.
No [0] = Don’t use (default).
Yes [1] = Use.
Note: This Domain name is used, instead of Proxy name or Proxy IP address, in the
INVITE SIP URL.
Always Use Proxy
[AlwaysSendToProxy]
No [0] = Use standard SIP routing rules (default).
Yes [1] = All SIP messages and Responses are sent to Proxy server.
Note: Applicable only if Proxy server is used.
Send All Invite to Proxy
[SendInviteToProxy]
No [0] = Invite messages, generated as a result of Transfer or Redirect, are sent
directly to the URL (according to the refer-to header in the REFER message or contact
header in 30x response) (default).
Yes [1] = All Invite messages, including those generated as a result of Transfer or
Redirect are sent to Proxy.
Note: Applicable only if Proxy server is used and “AlwaysSendtoProxy=0”.
Enable Proxy Hot-Swap
[IsProxyHotSwap]
Enable Proxy Hot-Swap redundancy mode.
No [0] = Disabled (default).
Yes [1] = Enabled.
If Hot Swap is enabled, SIP Invite message is first sent to the primary Proxy server. If
there is no response from the primary Proxy server for ‘Number of RTX before Hot-Swap’
retransmissions, the Invite message is resent to the redundant Proxy server.
