These release notes support Cisco IOS Release 12.1(5)YH3. These release notes are updated as needed to describe new features, memory requirements, hardware support, software platform deferrals, and changes to the microcode or modem code and related documents.
These release notes describe the following topics:
Cisco IOS Release 12.1(5)YH3 is an Early Deployment (ED) release parented to Cisco IOS Release 12.1(5)T and supporting the Cisco VG200. This release provides transcoding and conferencing services for the Cisco VG200 platform. The platform and features delivered with this ED release will be incorporated into Cisco IOS 12.3(1)T and subsequent Cisco IOS 12.2(X)T releases.
The following new features are supported on the Cisco VG200 in Cisco IOS Release 12.1(5)YH3:
These features are of interest to enterprise customers wishing to deploy IP telephony at branch offices using a centralized Cisco CallManager architecture. Providing transcoding and conferencing services at the branch location reduces the utilization of the WAN connection bandwidth for conference calls and point-to-point Voice over IP (VoIP) calls between the branch location and other on-network locations.
This ED supports Cisco CallManager switchover and switchback to provide survivability in the event the primary Cisco CallManager manager fails at the Enterprise location. This release supports the new NM-HDV-FARM network module and allows the Cisco CallManager administrator to configure the network module to support up to 15 six-party conference calls or up to 60 transcoding sessions. The network module is equipped with two digital signal processor (DSP) SIMMs containing three DSPs each and can be expanded up to a total of five DSP SIMMs.
 |
Note The maximum number of transcoding sessions supported by one DSP or the number of participants allowed in a conference is reduced when compressed codecs are used. (See the "Limitations of This Release" section on page 3.) |
This section describes the system requirements for Cisco IOS Release 12.1 T:
At this time, Cisco IOS Release 12.1(5)YH3 supports only the Cisco VG200 hardware platform. The Cisco VG200 comes preconfigured with the required memory resources, which include:
Flash memory—8 MB
DRAM memory—32 MB
To determine the version of Cisco IOS software running on a Cisco VG200, log in to the router and enter the show version EXEC command:
router> show version
Cisco Internetwork Operating System Software
IOS (tm) VG200 Software (vg200-i6s-mz), Version 12.1.5(YH3), RELEASE SOFTWARE

For a list of bugs that have been resolved in this release, see the "Bug Fixes" section.
CSCdu12495
This does not affect the functionality of the conference or transcoding applications. However, once DSP resources are all allocated the next session creation will fail.
CSCdu60270
When a GSM FR party is brought into an ad hoc conference, the endpoint will fail to get into the conference. This will not affect meet-me conferences.
CSCdu83460
When a switchover or switchback occurs during active calls, the call will be preserved. However, when the users hung up, the resources are not cleared from the DSP Farm service.
CSCdv51806
The VG200 conference bridge uses an NM-HDV module, but it does not use or require a VIC card. During router initialization, the following informational message is reported:
%HDV-1-NO_DAUGHTER_CARD: HDV in slot 1
This is not an error and does not impact the operation of the product.
