Vanguard 7300 Series Call Not Transferred with ALT-Dest set in VST
When placing a call from either an FXS, FXO or E&M to H.323 and the destination
does not answer the phone (ALT_DEST_NO_ANSER) or the phone is busy
(ALT_DEST) and the alternate destination is either an FXS, FXO or E&M, there is
no audio. (DRCaa22329)
Workaround: At present, there is no workaround.
Vanguard 7300 Series Large QoS Parameter Values May Disable QoS
Although the QoS Parameter fields can be configured to a maximum of 1000 or
10000 (in case of IP Flow Table Size), this is subject to the node’s RAM availability.
The software checks the node for sufficient RAM to accommodate a QoS parameter
configuration. If the node’s memory size is less than the requirement for the
configuration, the software disables QoS. (DRCaa22432)
Workaround: Configure the minimum required parameters for QoS.
Incorrect Configuration Can Disable QoS Scheduler Feature
Vanguard 7300 Series
The sum of the %BW per custom PHB configured in the custom PHB menu must be
the same as the %BW for custom PHB configured in the Queueing and Scheduling
Profile Parameter. Failing to do so leads to the disabling of the QoS Scheduler
feature. For example, if the %BW for custom PHB in the Queueing and Scheduling
Profile parameter is set to zero, the %BW per custom PHB must all be zero to satisfy
the above condition. (DRCaa22433)
Workaround: At present, there is no workaround.
Vanguard 7300 Series Using the Same TCP Session for Local and
Remote Nodes
If the remote node initiates a call using SoTCP and the local node attempts to make a
call in the reverse direction over the same TCP session, a new session might be
required to make the call. (DRCaa22437)
Workaround: Include in the Mapping Table, all possible IP addresses that might be
used by a remote destination node. For more information, refer to the Serial Protocol
over TCP Manual (Part number T0100-06).
Vanguard 7300 Series CLI setscript with T1/VPMT does not Download
CLI setscript with T1/VPMT does not download after using the “getscript”. CLI
errors occur because the VPMT is configured before the voice port or the T1 port.
(DRFaa16143)
Workaround: If the CLI set script file includes the “create vpmt” statement, move it
behind the create virtual port statement. If the “set minimum-cpu” statement is in the
script file, turn on the debug mode.
Vanguard 7300 Series H.323 Limitation on Number of Calls
When a Vanguard 7300 is configured to use H.323, the total number of voice calls
over all H.323 ports is limited to 216. (DRCaa23314)
Workaround: Use 6.0S100 or if you require H.323 Supplementary Services Support,
a 6.1 based software patch will be available shortly. Please contact your customer
service representative.
