voip.allow-strict
BOOLEAN
0 : Enable strict routing
1 : Disable strict routing
0
Allow strict routing for SIP registration proxies. By default, proxies
specified for SIP registration will be configured as loose-routing
proxies. The loose-routing designation will be automatically
appended to each proxy address when the proxy is added to the
SIP Route header. Older proxies may be strict-routing (see IETF RFC
2543), not supporting loose routing (see IETF RFC 3261). Enable
this option if you are using strict-routing proxies. If this option is
enabled and you are specifying one or more loose-routing proxies
in the Proxy field, then you must manually add the suffix to each
loose-routing proxy address. For example, “10.134.123.101;lr”.
voip.stun-srv
TEXT
stun-address : String. IP address,
domain name, or host name, and
optional port number. Separate
multiple addresses by comma.
Specifies the STUN (Session Traversal Utilities for NAT) server IP
address or name to use to determine if the phone is behind a NAT,
the type of NAT, and the public address of the phone. The field can
contain a comma separated list of servers. Each server can be a
domain name, host name, or IP address, and it may contain an
optional port number. (For STUN see IETF RFC 5389.)
voip.use-ice
BOOLEAN
0 : Disable ICE
1 : Enable ICE
0
Enables the use of the ICE (Interactive Connectivity Establishment)
protocol for NAT traversal. ICE takes advantage of STUN and TURN
to identify candidates (IP addresses and ports) for communication,
evaluating and prioritizing the candidate pairs to select the best
route. Expensive candidates, such as using a media relay, are
selected only as a last resort. (For ICE see IETF RFC 5245.)
