3.4.7.1.2 Proxy & Registration Parameters
The 'Proxy & Registration' page allows you to configure parameters that are associated with
Proxy and Registration.
Note:
SIP User's Manual
The valid range is a string of up to 10 characters. The default is an empty
string.
Determines how the device reacts to forking of outgoing INVITE messages
by the Proxy.
[0] Sequential handling = The device opens a voice stream toward the
first 18x SIP response that includes an SDP, and disregards any 18x
response with an SDP received thereafter (default).
[1] Parallel handling = The device opens a voice stream toward the first
18x SIP response that includes an SDP, and re-opens the stream
toward any subsequent 18x responses with an SDP.
Note: Regardless of the ForkingHandlingMode value, once a SIP 200 OK
response is received, the device uses the RTP information and re-opens
the voice stream, if necessary.
Enables / disables the usage of the SIP Reason header.
[0] Disable.
[1] Enable (default).
The time interval (in msec) between the first transmission of a SIP
message and the first retransmission of the same message.
The default is 500.
Note: The time interval between subsequent retransmissions of the same
SIP message starts with SipT1Rtx and is multiplied by two until SipT2Rtx.
For example (assuming that SipT1Rtx = 500 and SipT2Rtx = 4000):
The first retransmission is sent after 500 msec.
The second retransmission is sent after 1000 (2*500) msec.
The third retransmission is sent after 2000 (2*1000) msec.
The fourth retransmission and subsequent retransmissions until
SIPMaxRtx are sent after 4000 (2*2000) msec.
The maximum interval (in msec) between retransmissions of SIP
messages.
The default is 4000.
Note: The time interval between subsequent retransmissions of the same
SIP message starts with SipT1Rtx and is multiplied by two until SipT2Rtx.
Maximum number of UDP transmissions (first transmission plus
retransmissions) of SIP messages.
The range is 1 to 30. The default value is 7.
To view whether the device or its endpoints have registered to a SIP
Registrar/Proxy server, refer to Registration Status.
