The following are the endpoint requirements for the Cisco Unified MeetingPlace H.323/SIP IP Gateway:

Cisco Unified IP Phone that is configured to work with one of the following applications:

Cisco Unified CallManager Release 3.22 or a later release

Cisco SIP Proxy Server Release 1.0 or a later release

H.323 endpoints

PSTN phone that is connected to a configured voice gateway

Network Requirements

For the Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.2.1 server to communicate with the Cisco Unified MeetingPlace Audio Server, ensure that your network meets the following requirements:

The Cisco Unified MeetingPlace Audio Server and the Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.2.1 server must be located on the same subnet.

The Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.2.1 server must be inside the corporate firewall and must be able to access the softswitch—for example, Cisco Unified CallManager, H.323 gatekeeper, or Cisco SIP Proxy Server—by using H.323 or SIP.

The Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.2.1 server must be able to open a TCP connection on port 5003 when connecting to a Cisco Unified MeetingPlace Audio Server.

The secondary Ethernet connections—those that are connected to the Multi Access Blade and not the second Ethernet port on the CPU card—on the Cisco Unified MeetingPlace Audio Server must be connected to the same subnet as the corporate network to which your Cisco Unified IP phone is connected.

The Ethernet switch port or any other network devices to which the Multi Access Blade connects directly must be set to fixed 100Base-TX full duplex; if not, you may experience decreased voice quality.

If G.711 codec is configured, a dedicated 100 Mbps subnet is required for each MA-16 connection; if not, the voice quality may be degraded.

From the Cisco Unified MeetingPlace H.323/SIP IP Gateway server standpoint, the IP address of the Cisco Unified MeetingPlace Audio Server must not be translated by using a Network Address Translation (NAT) routing scheme.

Connectivity between the Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.2.1 server and the Cisco Unified MeetingPlace Audio Server must be high quality and not subject to interruptions because of traffic congestion. Any time the round-trip latency exceeds 100 milliseconds or there is more than one percent packet loss, expect a noticeable reduction in service quality.

If Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.2.1 is installed on a server with more than one IP address, for outdials to work you must define a gateway for each IP address either in Cisco Unified CallManager, Cisco SIP Proxy Server, or H.323 Gatekeeper.

Cisco Unified MeetingPlace Product Compatibility Matrix

For information about the compatibility of Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.2.1 with Cisco Unified MeetingPlace components, see one of the following:

The "Cisco Unified MeetingPlace Product Compatibility Matrix" section in the Installation Planning Guide for Cisco Unified MeetingPlace Release 5.3.

The Compatibility Matrix: Cisco Unified MeetingPlace Components document at http://www.cisco.com/en/US/products/sw/ps5664/ps5669/products_device_support_tables_list.html.


Note Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.2.1 is not compatible with Cisco Security Agent (CSA). We recommend that you do not install CSA on a gateway server where Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.2.1 is or will be installed.

If CSA is installed on an end-user system, users will see a security alert when they attempt to use the application-sharing feature. Users can choose to proceed with the feature and use application-sharing without difficulty.

Documentation Updates for the Cisco MeetingPlace IP Gateway System Manager's Guide, Release 5.2.0

Errors

This section lists changes to the current Cisco Unified MeetingPlace H.323/SIP IP Gateway documentation and gives corrected information. The correct information will be incorporated in a future documentation release.

Information About Configuring Cisco Unified MeetingPlace H.323/SIP IP Gateway Software Release 5.2.1 for Use WithCisco Unified MeetingPlace Web Conferencing

In the "Information About ConfiguringCisco Unified MeetingPlace H.323/SIP IP Gateway Software Release 5.2.1 for Use With Cisco Unified MeetingPlace Web Conferencing" section in the "Configuring Cisco Unified MeetingPlace H.323/SIP IP Gateway Software" chapter, the first paragraph is incorrect. The second sentence should be removed so the first paragraph will read as follows:

You can install Release 5.2.1 on either the same or separate server as Cisco Unified MeetingPlace Web Conferencing. Release 5.2.1 uses the primary address, and you must configure Cisco Unified MeetingPlace Web Conferencing to use the secondary address. If Release 5.2.1 is installed on a server with more than one IP address, you must define a gateway for each IP address either in Cisco Unified CallManager, Cisco SIP Proxy server, or H.323 Gatekeeper for outdials to work.

How to Configure Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.2.1 for Use With Cisco Unified MeetingPlace Web Conferencing

The "How to Configure Cisco Unified MeetingPlace H.323/SIP IP Gateway Software Release 5.2.1 for Use With Cisco Unified MeetingPlace Web Conferencing" section in the "Configuring Cisco Unified MeetingPlace H.323/SIP IP Gateway Software" chapter should be removed entirely.

Using MeetingPlace IP Gateway with MeetingPlace Web (Release 5.3 and later only)


Note The following change is only for systems that are using Cisco Unified MeetingPlace Web Conferencing Release 5.3 and later. If you are using Cisco Unified MeetingPlace Web Conferencing Release 5.2.1 or earlier, keep the document as is and do not make this change.


In the "Using MeetingPlace IP Gateway with MeetingPlace Web" section in the "Managing Cisco MeetingPlace IP Gateway" chapter, the first paragraph is not accurate for this release. Disregard the second and third sentences so the first paragraph will read as follows:

MeetingPlace IP Gateway can be installed on either the same or separate Windows server as MeetingPlace Web.

In this same section, disregard the following subsections entirely:

"Assigning the Primary IP Address"

"Assigning the Secondary IP Address"

"Assigning a Fixed Address"
