Known Software Limitations Page 46 of 99
Workaround: The three digit Hunt Group must be used. If you need to target a virtual
port, that virtual port should have a unique Hunt Group value.
Software Image Naming Convention is Different - Alternate and Current
Vanguard 7300 Series
The software image naming convention is different for the Vanguard 7300 platform.
In the Vanguard 7300 platform, you are able to boot from the Alternate image and
the system shows that it was booted from Alternate. The Alternate image does not
become the Current image, as in the other Vanguard products. (DRCaa22270)
Note
When using the other (non-73xx) Vanguard products, when you boot from
Alternate, the Alternate image becomes the Current image.
Workaround: At present, there is no workaround.
Vanguard 7330 Power Supplies
When the Vanguard 7330 Version 1 or a 7310 or 7330 Version 2 is configured with
multiple power supplies, each power supply shares the load. If a power supply
should enter a failure condition, the second power supply provides power for the
entire system. Failure conditions can be determined by viewing the LED on each
power supply. Power supply fail conditions are not reported as alarm conditions
through the CTP menu or SNMP trap. The only failure indication is the LED
associated with the failed power supply. If one of the power supplies fail, you will be
operating in a non-redundant mode. (DRCaa22496)
Workaround: None. Periodically check the power supply LEDs.
RTP+UDP Compression - Vanguard 6455
Compression may not occur on LCONs with RTP and UDP compression enabled,
(RTP or RTP+UDP) when non-RTP UDP packets are passed over the LCON. The
characteristics of the user data portion of the UDP packet can cause all the transmit
compression contexts to be consumed such that no compression occurs. This
condition may persist while the non-RTP UDP data is present on the LCON. Once
the data is removed, the contexts are released. (DRCaa22524).
Workaround: Configure UDP compression only on links which carry RTP and UDP
traffic. Limit non-RTP UDP data to a range of ports not configured for RTP
compression.
Vanguard 7300 Series H.323 Statistics
In certain configurations, once a call is established, the PSTN port statistic show that
TX and RX pps do not match the H.323 port statistics. The H.323 port pps rate is 1 or
2 pps less than the PSTN port. It should be equal. (DRFaa18071)
Workaround: At present, there is no workaround.
Vanguard 7300 Series Embedded Web Group Configuration
When you configure the voice port interface type (FXS), the next parameter is
Signaling Mode. When you change the port interface type to E&M, the next
parameter should change to Signal Type. Currently the next menu displayed is
Signaling Mode. (DRFaa18769)
Workaround: At present, there is no workaround.
