(IP:Port;Transport
Type)
1
IP Address, Port & Transport
Type
10.10.10.10:5060;UDP
2 IP Address only 10.10.10.10:5060;UDP
3 IP Address only 10.10.10.10:5070;UDP
4 IP Address only 10.10.10.10:5060;TCP
✔ Incoming SIP request from 10.10.10.10:5060;UDP:
Best match is #1 and #2 (same priority); second best
match is #3 (due to transport type); third best match is #4.
✔ Incoming SIP request from 10.10.10.10:5080;TLS: Best
match is #2, #3 and #4 (same priority).
✔ Incoming SIP request from 10.10.10.10:5070;TCP: Best

'DNS Resolve Method'
dns-resolve-
method
[ProxySet_
DNSResolveMethod]
Defines the DNS query record type for resolving the proxy server's
host name (FQDN) into an IP address(es).
■ [-1] = Not configured. DNS resolution method is according to
the settings of the global parameter, ProxyDNSQueryType.
■ [0] A-Record = (Default) DNS A-record query is used to
resolve DNS to IP addresses.
■ [1] SRV = If the proxy address is configured with a domain
name without a port (e.g., domain.com), an SRV query is done.
The SRV query returns the host names (and their weights). The
device then performs DNS A-record queries per host name
(according to the received weights). If the configured proxy
address contains a domain name with a port (e.g.,
domain.com:5080), the device performs a regular DNS A-
record query.
■ [2] NAPTR = NAPTR query is done. If successful, an SRV
query is sent according to the information received in the
NAPTR response. If the NAPTR query fails, an SRV query is
done according to the configured transport type. If the
configured proxy address contains a domain name with a port
(e.g., domain.com:5080), the device performs a regular DNS A-
record query. If the transport type is configured for the proxy
address, a NAPTR query is not performed.
