Known Software Limitations Page 18 of 97
Only the first 155 entries in the Virtual Port Mapping Table are usable
(CR16941)
Workaround: Limit configuration to the first 155 VPMT table entries.
Booting an IPSEC Tunnel is not supported. (CR17196)
Booting an IPSEC tunnel configured as dynamic is not supported.
Work Around:
If a configuration needs to be booted-in for a dynamic tunnel, then a node
boot is required.
Voice ports configured as digital digital voice ports should not be allowed to be
set for DSP Option 4 (CR17351).
DSP Option 4 is only supported on the Quad FXS/FXO interfaces. Digital
Voice Ports are currently able to be set to DSP Option 4 by both the Node
level DSP Image Selection and the DSP Image Selection in the Voice Port
Configuration Menu. This setting for the Digital Voice Ports is NOT sup-
ported and could cause incorrect behavior.
Work Around:
The user must insure that no Digital Voice Ports are set to DSP Option 4.
The Voice Port Configuration CTP Entry Checking Feature for the DSP Option
4 VAD functions only for the Voice Port Master Port (CR17352).
Currently, there is a checking feature for the VAD CTP setting to insure the
user selects VAD Disabled when changing a Master Port to DSP Option 4.
Work Around:
The CTP Entry checking function for Slave Ports currently does not work
correctly, therefore the user must then go to each slave port and set VAD to
Disabled.
An Incorrect Error Message is Logged when the Wron Fax Configuration
Exists(CR17353).
When a users wants to change an existing DSP image selection to Option 4 on
the Master Voice Port, they will be prompted to change the VAD and Fax set-
ting to their proper values (disabled&T.38). If the users forgets to make the
appropriate changes to the Slave Ports and boots the node, the incorrect event
meesage is displayed.
Work Around:
The users needs to be aware that the wrong error message may be displayed.
