Table 5-9: Proxy & Registration Parameters
Enables the use of DNS Naming Authority Pointer (NAPTR) and Service
Record (SRV) queries to discover Proxy servers.
Valid options include:
[0] A-Record = A-Record (default)
[1] SRV = SRV
[2] NAPTR = NAPTR
If set to A-Record [0], no NAPTR or SRV queries are performed.
If set to SRV [1] and the Proxy IP address parameter contains a domain
name without port definition (e.g., ProxyIP = domain.com), an SRV query is
performed. The SRV query returns up to four Proxy host names and their
weights. The gateway then performs DNS A-record queries for each Proxy
host name (according to the received weights) to locate up to four Proxy IP
addresses. Therefore, if the first SRV query returns two domain names, and
the A-record queries return two IP addresses each, no more searches are
performed.
If set to NAPTR [2], an NAPTR query is performed. If it is successful, an
SRV query is sent according to the information received in the NAPTR
response. If the NAPTR query fails, an SRV query is performed according to
the configured transport type.
If the Proxy IP address parameter contains a domain name with port
definition (e.g., ProxyIP = domain.com:5080), the gateway performs a
regular DNS A-record query.
Note: When enabled, NAPTR/SRV queries are used to discover Proxy
servers even if the parameter DNSQueryType is disabled.
This parameter is obsolete; use the parameter DNSQueryType.
This parameter is obsolete; use the parameter ProxyDNSQueryType.
Determines the method the gateway uses to subscribe to an MWI server.
[0] Per Endpoint = Each endpoint subscribes separately. This method is
typically used for FXS modules (default).
[1] Per Gateway = Single subscription for the entire gateway. This
method is typically used for FXO gateways.
[0] No = Use the gateway's IP address in keep-alive OPTIONS
messages (default).
[1] Yes = 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 (EnableProxyKeepAlive = 1).
