Table 6-50 Field Descriptions for the VXSM XGCP Tab, Media Gateway XGCP Configuration
Category
Field Name Description
Request Timeout
(milliseconds)
Period that the XGCP (TGCP) protocol waits before re-transmitting an
unacknowledged message. It is the responsibility of the requesting entity to
provide suitable timeouts for all outstanding commands, and to retry
commands when timeouts exceeded.
MG Max Exp Retry
Timeout
(milliseconds)
Specifies the maximum timeout for exponential command retry by the media
gateway.
Max Waiting Delay
Timeout
(milliseconds)
Value used for the media gateway to send the first restart in progress to the
MGC in an implementation-dependent manner by the MGCP functionality
based on the call volume of the system.
Restart Delay
(seconds)
Specifies the restart delay timeout for the restart process for a gateway to send
out RestartInProgress when it is powered on or has been reset.
Default Package Represents the default capability package supported in the gateway.
Supported Packages Represents the bit map of MGCP supported packages.
Simple SDP Enabled Used to enable or disable building of s, t, and o lines in the Sessions
Description Protocol (SDP) message. The o field indicates the owner/creator
and session identifier. The s field indicates the session name field. The t field
indicates the duration while a session is valid. A value of true (enabled) means
that SDP will NOT include the fields s, t, and o. A value of false (disabled)
means that the o, s, and t lines will be built before sending SDP.
AckSDP Enabled Specifies if the ACK SDP is enabled or disabled. If the value is true (enabled)
it sends ADP with ACK when CODEC or reportable NTE delta changed, or an
attempt is made to change CODEC, VAD, packet-period, echo cancellation
during FAX/modem mode.
Undotted Notation
Enabled
Enables or disables the undotted notation for CODEC. This object is used to
set CODEC notation to dotted or undotted in SDP between the gateway and
the call agent.
Process Quarantine
Events
Determines how to handle persistent events. If the value is true, the
quarantined events should be processed, otherwise the quarantined events are
discarded.
Quarantine Loop
Enabled
Controls the default quarantine mode. If the value is true, the default
quarantine mode is loop and not step. The gateway is expected to generate
multiple notifications (loop) not at most one notification
Bypass Quarantine
Buffer
Specifies how the persistent events will be handled in quarantine processing.
If the value is true, the persistent events bypass quarantine buffer. If the value
is set to false, this object will be ignored.
Piggyback Message
Enabled
Enables or disables the piggyback message generation. If the value is true, a
call agent can send several MGCP messages in the same UDP packets to the
gateway.
Max XGCP Msg Size
(bytes)
Specifies the maximum allowed XGCP (TGCP) message size which is used
for checking if the size will be supported by the call agent via (AuditEndPoint)
response. A value of zero means there is no limit to the size of the XGCP
message.
