Note:
■ Ensure that the parameter value is the one with which the
Proxy has been configured with to identify the device.
■ The parameter can also be configured for an IP Group (in the
IP Groups table).
Determines the device's response to an incoming SDP that
includes an IP address of 0.0.0.0 in the SDP's Connection
Information field (i.e., "c=IN IP4 0.0.0.0").
■ [0] = (Default) Sets the IP address of the outgoing SDP's c=
field to 0.0.0.0.
■ [1] = Sets the IP address of the outgoing SDP c= field to the
IP address of the device. If the incoming SDP doesn't contain
the "a=inactive" line, the returned SDP contains the
"a=recvonly" line.
Determines whether the device sends the initial INVITE
message with or without an SDP. Sending the first INVITE
without SDP is typically done by clients for obtaining the far-
end's full list of capabilities before sending their own offer. (An
alternative method for obtaining the list of supported capabilities
is by using SIP OPTIONS, which is not supported by every SIP
agent.)
■ [0] Disable = (Default) The device sends the initial INVITE
message with an SDP.
■ [1] Enable = The device sends the initial INVITE message
without an SDP.
Defines whether the device includes or excludes URI parameters
for the Digest URI in the SIP Proxy-Authorization or
Authorization headers of the request that the device sends in
reply to a received SIP 401 (Unauthorized) or 407 (Proxy
Authentication Required) response. Below shows an example of
a request with an Authorization header containing a Digest URI
(shown in bold):
Authorization: Digest username="alice at
AudioCodes.com",realm="AudioCodes.com",nonce="
",response="",uri="sip:AudioCodes.com"
■ [0] = (Default) The device sends the request without a Digest
URI.
■ [1] = The device sends the request with a Digest URI, which
is set to the same value as the URI in the original Request-
URI.
Enables the device to send "a=crypto" lines without the lifetime
parameter in the SDP. For example, if the SDP contains
"a=crypto:12 AES_CM_128_HMAC_SHA1_80
inline:hhQe10yZRcRcpIFPkH5xYY9R1de37ogh9G1MpvNp|2^3
1", it removes the lifetime parameter "2^31".
■ [0] Disable (default)
■ [1] Enable
