Open Caveats for Cisco Unified Videoconferencing Gateway 3500 Release 5.0
This section lists possible unexpected behaviors by Cisco Unified Videoconferencing Gateway 3500 Release 5.0 and is sorted by gateway product.
All Cisco Unified Videoconferencing Gateway 3500 Products
•Upgrade/downgrade problems may occur due to lack of memory. If the "Upgrade process failed: The uploaded file size is larger than the maximum available memory" message displays in the Upgrade Utility, manually reboot the board and retry the upgrade.
•When using TANDBERG 1500 MXP on the IP side, it may take about 20 seconds for the video channel to open from the MXP to the Gateway.
•The start of the IVR message is missing in calls from an ISDN Polycom VSX endpoint.
•H.239 interoperability issues may occur when working with eConf.
•H.239 interoperability issues occur in calls between a TANDBERG ISDN 990MXP endpoint and a Polycom VSX LAN endpoint.
•H.235 interoperability issues may occur when working with a TANDBERG 4.1 endpoint. The audio channel from the endpoint via the Gateway may fail to open as an encrypted channel. In such cases, the Gateway will disconnect the call.
•H.239 supports only the H.263 codec in the second video channel. H.264 is not supported.
•We recommend that you use an MVP when working with the MCU in H.239 mode.
•When working in Peer-to-Peer mode, the front Gatekeeper (GK) LED is always lit.
•Video may freeze in calls between ISDN Polycom FX and IP TANDBERG MXP.
Cisco Unified Videoconferencing 3527 PRI Gateway, 3522 BRI Gateway and 3545 PRI Gateway
•Difficulties may occur when using Fast Start. We recommend that you do not activate Fast Start.
•H.239 is not supported in 2*B calls.
Cisco Unified Videoconferencing 3545 Serial Gateway
•Connection problems occur in IP-to-IP calls via two Serial Gateways using Polycom VSX 7000.
•We recommend that you use Microsoft Explorer version 5.0 or later as your browser.
•Interoperability issues may occur with Aethra Maia384 on the ISDN. Solve the problem by sending the ChangeBondingCID advanced command with the parameter value "enable" to the Gateway.
•Calls my fail when using TANDBERG endpoints on the ISDN with the bit rate set to "Auto". Solve the problem by sending the ClearBondXflag advanced command with the parameter value "enable" to the Gateway.
•When making a 128 Kbps call from an ISDN Sony PCS-1, H.239 may not open correctly. Increasing the call bit rate solves this issue.
•H.239 interoperability issues may occur when working with Aethra endpoints on the ISDN when making a TCS4 or IVR call. Solve this issue by sending the SimulateVideoOff advanced command with the parameter value "enable".
•When working with VSX300 on the ISDN side, if using G.722.1 with H.263, there will be no video seen in the VSX. Disable the G.722.1 in the GW media modes in order to solve this issue.
•When using G.722.1 with H.263, video is lost on a Polycom VSX300 ISDN endpoint. Solve this problem by disabling G.722.1 in the Media Modes section of the Gateway Settings tab.
•Opening an H.239 channel to a TANDBERG MXP on the ISDN side may fail. Simply retry and the channel will open successfully.

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—An existing network is down, or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of the network is impaired, while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
