Compatibility Matrix and Supported Upgrades
See the following sections for software compatibility information.
Cisco MeetingPlace Software
Cisco MeetingPlace IP Gateway Release 5.2 is compatible with all MeetingPlace products that are shown in Table 1 and can be installed on the same server either as MeetingPlace Web plus one notification gateway or as a standalone.
Cisco MeetingPlace Web
To enable web conferencing on the same server as the Cisco MeetingPlace IPGW, configure the server with two IP addresses to the same LAN interface card.
You can install Cisco MeetingPlace IPGW on either the same system as MeetingPlace Web or on a standalone system. If you are installing on the same system as MeetingPlace Web, you must configure an additional IP address. Refer to the Cisco MeetingPlace IP Gateway System Manager's Guide Release 5.2 for more information.
New and Changed Information
Cisco MeetingPlace IP Gateway 5.2 includes the following new major features. For full feature descriptions or configuration information, refer to the Cisco MeetingPlace IP Gateway System Manager's Guide Release 5.2.
Cisco MeetingPlace 8100 series systems can now scale to a maximum of 960 IP ports. All current Cisco MeetingPlace features, including in-session features, are identical for T1, E1, and IP ports. For more information, refer to "Telephony and LAN Planning" section in the Cisco MeetingPlace Audio Server 5.2 Installation Planning Guide.
SIP Protocol Support
Session Initiation Protocol (SIP) is an IP telephony protocol that was developed by the Internet Engineering Task Force (IETF). SIP is modular in nature and provides extensions for presence and mobility applications. Cisco MeetingPlace IP Gateway Release 5.2 now supports SIP in addition to H.323 for IP call control and can handle both H.323 and SIP calls simultaneously, adding flexibility to environments that use multiple IP call controls.
G.729a Compression Codec Support
Cisco MeetingPlace IP Gateway Release 5.2 currently supports G.711 codecs; these codecs can take up to 64 Kbps of bandwidth per call and have the best voice quality of all available codecs. When deploying Voice over IP, customers may decide to use the G.729, a compression codec for connections where bandwidth is scarce. For this reason, Cisco MeetingPlace IPGW also supports G.729, a compression codec that is used for conferencing. However, G.711 is recommended for optimal voice quality.
Hold and Transfer Feature
Cisco MeetingPlace IP Gateway Release 5.2 now enables users to put a line on hold, including a line to a Cisco MeetingPlace conference. From the handset, users can take a separate call on a multiline phone, and in the same way, users can perform simple phone transfers via the handset during meetings.
Multiple IP Gateways
You can deploy multiple Cisco MeetingPlace IPGWs against a single Cisco MeetingPlace 8100 series system to provide load balancing and system redundancy. Calls are routed round-robin to the IPGWs. If one IPGW fails, calls that are in session will fail; however, new callers will be routed to an alternate IPGW to connect with the Cisco MeetingPlace Audio Server.
Registration, Admission, and Status Support
Registration, Admission, and Status (RAS) is part of the H.323 protocol, and RAS manages IP devices through registration with a gatekeeper. Though typically not required for Cisco CallManager or other call processing systems, RAS may be needed for integrated IP video. Cisco MeetingPlace IPGW can now support registration requirements on an IP network.
Resolved Caveats for Cisco MeetingPlace IPGW Release 5.2
Symptom: End user on IP phone hears fast busy when PSTN phone leaves the meeting.
Condition: During a meeting with participants on both PSTN phones and IP phones, participants on IP phones may hear a brief dial tone when participants on PSTN phones leave the meeting.
Symptom: Ringing to IP phone does not stop when the caller disconnects.
Condition: When a user outdials to an IP phone but then disconnects the call before the phone is answered, the IP phone may continue to ring for an additional minute. If the phone is answered during this period, the call disconnects or the participant hears a fast busy tone.
Symptom: IP services need to be restarted twice to run properly after an upgrade.
Condition: After upgrading the MeetingPlace IP Gateway, the MeetingPlace IP Gateway service may need to be stopped, then started a couple times to properly handle IP calls.
Symptom: MeetingPlace icon is missing in the taskbar.
Condition: After installing Cisco MeetingPlace IP Gateway service, the Cisco MeetingPlace icon in the taskbar may be missing.
Workaround: The icon can be recovered by running MPLaunch.exe, which is located in the Cisco MeetingPlace Gateway SIM folder.
Open Caveats for Cisco MeetingPlace IPGW Release 5.2
The following open caveats describe possible unexpected behaviors by Cisco MeetingPlace IPGW Release 5.2:
Symptom: H.323 IP calls cannot be placed on hold.
Condition: Participants using Cisco IP phones cannot place a call to Cisco MeetingPlace on hold; otherwise, the call is disconnected.
Symptom: Registry settings are reset after upgrading IP gateway software.
Condition: An upgrade to the MeetingPlace IP Gateway resets the configuration settings to the default values.

If your issue is not resolved using the recommended resources, your service request will be assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:

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)—Your 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 operation 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 your network is impaired, but 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.
