Mediant 2000
Parameter
Description
The valid range is a string of up to 10 characters. The default is an empty
string.
Forking Handling Mode
[ForkingHandlingMod
e]
Determines how the device reacts to forking of outgoing INVITE messages
by the Proxy.
ƒ
[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).
ƒ
[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.
Enable Reason Header
[EnableReasonHeade
r]
Enables / disables the usage of the SIP Reason header.
ƒ
[0] Disable.
ƒ
[1] Enable (default).
Retransmission Parameters
SIP T1 Retransmission
Timer [msec]
[SipT1Rtx]
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):
ƒ
The first retransmission is sent after 500 msec.
ƒ
The second retransmission is sent after 1000 (2*500) msec.
ƒ
The third retransmission is sent after 2000 (2*1000) msec.
ƒ
The fourth retransmission and subsequent retransmissions until
SIPMaxRtx are sent after 4000 (2*2000) msec.
SIP T2 Retransmission
Timer [msec]
[SipT2Rtx]
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.
SIP Maximum RTX
[SIPMaxRtx]
Maximum number of UDP transmissions (first transmission plus
retransmissions) of SIP messages.
The range is 1 to 30. The default value is 7.
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: To view whether the device or its endpoints have registered to a SIP
Registrar/Proxy server, refer to Registration Status.
