cnfxgcpretry
cnfxgcpretry
To configure VISM minimum and maximum request timeouts and retransmission attempts for
communication with the associated call ag ent, u se t he cnfxgcpretry command in the VoIP
switching/trunking and switched AAL2 PVC operating modes.
cnfxgcpretry min-vtoca-tout vtoca-retrans-num |max-vtoca-tout|
Syntax Description
Command Modes VoIP switching/trunking and switched AAL2 PVC
Usage Guidelines If you indicate a value for the optional max-vtoca-tout argument, VISM exponentially increases the
timeout value between the minimum and maximum timeouts. If a maximum value is not specified, the
max-vtoca-tout value is set equal to the min-vtoca-tout value, which disables the exponential backoff.
Examples The following example shows that VISM will wait a minimum time of 1000 ms and a maxi mum tim e o f
2000 ms for an acknowledgment message from the call agent, and three call agent retransmission
attempts will occur before VISM is determined to be unreachable:
cnfxgcpretry 1000 3 2000
