Introduction

Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.3 works with the Cisco Unified MeetingPlace Audio Server to provide meeting access to callers. The gateway supports up to 960 IP connections. The Audio Server supports connections from up to 16 IP gateway servers; this multigateway support provides network load balancing and system redundancy.

Compatibility Information

System Requirements for Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.3

System Requirements for Cisco Unified MeetingPlace Release 5.4 and System Requirements for Cisco Unified MeetingPlace Release 6.0 contain the most current information on H.323/SIP IP Gateway requirements. These documents are available at http://www.cisco.com/en/US/products/sw/ps5664/ps5669/prod_installation_guides_list.html.

Compatibility Information

For information about the compatibility of H.323/SIP IP Gateway Release 5.3 with other Cisco Unified MeetingPlace components, see the Compatibility Matrix: Cisco Unified MeetingPlace Components at http://www.cisco.com/en/US/products/sw/ps5664/ps5669/products_device_support_tables_list.html.


Caution Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.3 is not compatible with Cisco Security Agent. We recommend that you do not install Cisco Security Agent on a gateway server where H.323/SIP IP Gateway Release 5.3 is or will be installed. If Cisco Security Agent 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.

Release 5.3(1.61)

Release 5.3(1.40)

Release 5.3(1.29)

Release 5.3(1.5)

Release 5.3(1.61)

Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.3(1.61) is a maintenance release that contains fixes to defects and product enhancements. See the "Caveats" section for a list of these defects and enhancements.

Release 5.3(1.40)

Removed the management console. System administrators now use the Gateway Configuration utility to configure the Cisco Unified MeetingPlace H.323/SIP IP Gateway. See CSCsg62366 for more information.

Release 5.3(1.29)

Support Session Timer in SIP

Redundant Gateway Configuration

Support Session Timer in SIP

Added two new fields to reduce the impact of voice gateway outages:

Session Expires Time (in registry Session-Expires Time) DWORD. This parameter determines how many seconds will elapse before the call is ended if no response is received for the re-INVITE message that the Cisco Unified MeetingPlace H.323/SIP IP Gateway sends. The default value of this parameter is 1800, and the limits are 90 to 86400. If a user sets this value outside the 90 to 86400 interval, then the system uses the default value of 1800.

MinSE DWORD. This parameter determines the Minimum Session-Expires value that the party that should respond to re-INVITE will accept. The default value of this parameter is 1800, and the limits are 90 to 86400. If a user sets this value outside the 90 to 86400 interval, the system uses the default value of 1800.


Note The value of the Minimum Session-Expires parameter must be less than or equal to the value of the Session-Expires parameter; otherwise, the value of the Minimum Session-Expires parameter defaults back to the value of the Session-Expires parameter whenever the Cisco Unified MeetingPlace H.323/SIP IP Gateway is restarted.


In this release, the Cisco Unified MeetingPlace H.323/SIP IP Gateway sends re-INVITE messages to maintain information about the availability of the other caller and to close audio server ports if the other caller is unavailable for a time period longer than the value of the Session-Expires parameter. It also handles different MinSE parameters when contacting the other caller to use the optimal value of the Session-Expires parameter for the other side.

Refer to SIP RFC 4028 for more details.

Redundant Gateway Configuration

Added support for two redundant voice gateways (for SIP) or H.323 gateways (for H.323) in the Cisco Unified MeetingPlace H.323/SIP IP Gateway configuration, for a total of three gateways that can be specified.

For example, if there are three gateways and gateway 1 fails, calls are routed to gateway 2. If that fails, calls go to gateway 3, and if that fails, call are routed back to gateway 1.

Failovers, which are for outdialed calls only, can occur for the following reasons. PSTN cause codes are included where applicable:

SIP Failovers

Generic timeout

SIP Response Code 404, when accompanied by the following PSTN cause codes:

2 No route to specified transit network

3 No route to destination

26 Non-selected user clearing

27 Destination out of order

SIP Response Code 500 Internal server error

SIP Response Code 503, when accompanied by the following PSTN cause codes:

34 No circuit available

38 Network out of order

41 Temporary failure

42 Switching equipment congestion

47 Resource unavailable

H.323 Failovers

All PSTN cause codes indicated above, and also

44 Requested circuit not available

102 Recovery on timer expiry

Release 5.3(1.5)

Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.3(1.5) is a maintenance release that contains fixes to defects and product enhancements. See the "Caveats" section for a list of these defects and enhancements.

Installing Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.3 for the First Time

For instructions on installing the H.323/SIP IP Gateway, refer to the "Installing Cisco Unified MeetingPlace H.323/SIP IP Gateway Software" chapter of the Administrator's Guide for Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.2.1 at http://www.cisco.com/en/US/products/sw/ps5664/ps5669/prod_maintenance_guides_list.html.

Upgrading to Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.3

Upgrading a legacy H.323/SIP IP Gateway system to Release 5.3 requires a legacy third-party Windows server with system specifications comparable to Cisco MCS specifications required for the same deployment. For information on Cisco MCS specifications, go to http://www.cisco.com/en/US/products/hw/voiceapp/ps378/index.html.

To upgrade the H.323/SIP IP Gateway, use the installation instructions in the "Installing Cisco Unified MeetingPlace H.323/SIP IP Gateway Software" chapter of the Administrator's Guide for Cisco Unified MeetingPlace H.323/SIP IP Gateway Release 5.2.1 at http://www.cisco.com/en/US/products/sw/ps5664/ps5669/prod_maintenance_guides_list.html.
