Command Parameters
Timers Parameters
Parameter | Length/Range | Description |
---|---|---|
bfcpTimer | N/A | Binary Floor Control Protocol (BFCP) re-transmission timer includes the following two timer variables:
|
nonNatKeepaliveTimer | 0-65535 | Use 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). |
sctpRetransmitTime | 0-15 | The retransmit timer (in seconds) for SIP request over SCTP. (default = 6). |
sessionKeepalive | 0-65535 | The SIP protocol session keep-alive timer (in seconds). (default = 1800). |
sessionMinSE | 0-65535 | Minimum expiration value (in seconds) accepted from a Session-Expires header (default = 90). NOTE: When |
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). |
sipSwitchoverKeepAliveDelay | 0-1024 | Enable a delay timer after switchover. The SBC continues retry with keepalive INVITE until the sipSwitchoverKeepAliveDelay timer is active. (default=0) |
suspendResumeTimer | N/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.
|
t1 | 1-10000 | 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). |
| 0-15 | The retransmit timer (in seconds) for SIP request over TCP. (default = 6). |
