Command Parameters

Timers Parameters

ParameterLength/RangeDescription
bfcpTimer N/A

Binary Floor Control Protocol (BFCP) re-transmission timer includes the following two timer variables:

    • reqTimerT1 – BFCP protocol request re-transmission timer T1 (in milliseconds). (range = 1-10000 / default = 500).

    • respTimerT2 – BFCP protocol response re-transmission timer T2 (in milliseconds). For the configured time all subsequent duplicate requests will respond by replaying the cached response. (range = 1-65535 / default = 10000).

nonNatKeepaliveTimer 0-65535Use this parameter to specify the keep-alive interval (in seconds) for a non-Nat'd device.(default = 60) 
ocsDialogTime 0-10080

This relay control block timer is restarted for each relay request received. If no request is received for this configured period, the dialog is deleted. When the timer is set to “0”, sessionKeepalive flag is disabled. (default = 1440 minutes).

sctpRetransmitTime0-15 

The retransmit timer (in seconds) for SIP request over SCTP. (default = 6).

sessionKeepalive0-65535

The SIP protocol session keep-alive timer (in seconds). (default = 1800).

sessionMinSE0-65535 

Minimum expiration value (in seconds) accepted from a Session-Expires header (default = 90).

NOTE: When sessionMinSE value is less than 90 seconds or when it equals 65535, SBC does not send an INVITE upon receiving "422 Session Interval Too Small" error message. 

sessionTerminationDeltaTime 0-65535

The time (in seconds) before session expiration at which the SBC sends a BYE if no session refresh request is received. This only applies when acting as the session keep-alive responder (i.e. not refresher) for a call. (default = 0).

suspendResumeTimerN/A 

If enabled, this timer starts counting when SUSPEND ISUP message is received in SIP MIME. The timer is cancelled upon receipt of RESUME ISUP message. 

  • state – Administrative state of timer (default is “disabled”) 
  • value – The suspend-resume timer value, in seconds (range: 1-720 / default = 30). 
  • type – Type of ISUP message to apply timer against. 
      • userTypeOnly 
      • networkTypeOnly   
      • both (default)
t11-10000 

The SIP protocol retransmission timer T1 (in milliseconds). T1 is an estimate of the round-trip time (RTT). (default = 500).

t2 1-65535 

The SIP protocol timer T2 (in milliseconds), and represents the maximum retransmit interval for non-INVITE requests and   INVITE responses. (default = 4000).

tcpRetransmitTimer

 0-15

The retransmit timer (in seconds) for SIP request over TCP. (default = 6).
