SIP User's Manual 3. Web-Based Management
Parameter Description
Enable VoiceMail URI
[EnableVMURI]
Enables or disables the interworking of target and cause for redirection
from Tel to IP and vice versa, according to RFC 4468.
 [0] Disable = Disable (default).
 [1] Enable = Enable
Upon receipt of an ISDN SETUP message with redirect values, the device
maps the Redirect phone number to the SIP 'target' parameter and the
Redirect number reason to the SIP 'cause' parameter in the Request-URI.
Redirecting Reason >> SIP Response Code
Unknown >> 404
User busy >> 486
No reply >> 408
Deflection >> 487/480
Unconditional >> 302
Others >> 302
If the device receives a Request-URI that includes a 'target' and 'cause'
parameter, the 'target' is mapped to the Redirect phone number and the
'cause' is mapped to Redirect number reason.
Retry-After Time
[RetryAfterTime]
Determines the time (in seconds) used in the Retry-After header when a
503 (Service Unavailable) response is generated by the device.
The time range is 0 to 3,600. The default value is 0.
Enable P-Associated-URI
Header
[EnablePAssociatedURI
Header]
Determines the device usage of the P-Associated-URI header. This header
can be received in 200 OK responses to REGISTER requests. When
enabled, the first URI in the P-Associated-URI header is used in
subsequent requests as the From / P-Asserted-Id headers value.
 [0] Disable (default).
 [1] Enable.
Note: P-Associated-URIs in registration responses is handled only if the
device is registered per endpoint (using the User Information file).
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):
 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.
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.
