IOS (tm) VG200 Software (vg200-i6s-mz), Version 12.1(3)T, RELEASE SOFTWARE
The Cisco VG200 supports only one software image, VG200-i6s-mz.
For general information about upgrading to a new software release, see the product bulletin, Cisco IOS Upgrade Ordering Instructions located on CCO at:
Service & Support: Software Center: Cisco IOS Software: Product Bulletins: Software
Under General System Software Bulletins, click Cisco IOS Upgrade Ordering Instructions, No. 957
This section contains important notes about the following topics:
When using an H.323 T1-CAS E&M port on the Cisco VG200, Incoming Caller ID Digits may not be processed correctly by Cisco IP IVR applications, such as Cisco IP Auto-Attendant.
Depending on the T1-CAS line provisioning, incoming DNIS digits received by the Cisco VG200 after its first wink to the Central Office (CO) are treated as user-entered digits and are sent to the remote endpoint as out-of-band DTMF digits. If the remote endpoint is a Cisco IP IVR application, the out-of-band digits will be interpreted as a user entry and change the application response. There are two ways to handle this situation:
When using the FXO ports on a Cisco VG200, set the input gain greater than 10 to achieve adequate audio quality for use with Cisco IP voice applications or the Cisco IP Phone 7960. Enter the following series of commands from the Cisco IOS command line to set the correct value for input gain:
vg200# configure terminal
vg200(config)# voice-port x/x/x input gain <value>
Permitted entries for <value> are from-6 to 14. Gain values higher than 12 may cause DTMF recognition difficulties.
Make sure that you use the MGCP configuration command for enabling DTMF relay. If this command is not configured, DTMF tones will be not be regenerated correctly on the remote endpoint. The required command is as follows:
router(config)# mgcp dtmf-relay codec all mode out-of-band
For further information about configuring MGCP, refer to the Software Configuration Guide for the Cisco VG200.
Older Cisco Management Information Bases (MIBs) will be replaced in a future release. OLD-CISCO-* MIBS are currently migrated into more scalable MIBs—without affecting existing Cisco IOS products or NMS applications. You can update from deprecated MIBs to the replacement MIBs as shown in Table 2.
| Deprecated MIB | Replacement |
|---|---|
OLD-CISCO-CHASSIS-MIB | ENTITY-MIB |
OLD-CISCO-CPUK-MIB | In Development |
OLD-CISCO-ENV-MIB | CISCO-ENVMON-MIB |
OLD-CISCO-FLASH-MIB | CISCO-FLASH-MIB |
OLD-CISCO-INTERFACES-MIB | IF-MIB-CISCO-QUEUE-MIB |
OLD-CISCO-IP-MIB | In Development |
OLD-CISCO-MEMORY-MIB | CISCO-MEMORY-POOL-MIB |
OLD-CISCO-SYS-MIB | (Compilation of other OLD* MIBS) |
OLD-CISCO-SYSTEM-MIB | CISCO-CONFIG-COPY-MIB |
OLD-CISCO-TCP-MIB | CISCO-TCP-MIB |
OLD-CISCO-TS-MIB | In Development |
Caveats describe unexpected behavior or defects in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious, and severity 3 caveats are still less serious.
The following severity 3 caveats are specific to Cisco IOS Release 12.1(3)T when used with the Cisco VG200.
vg200# configure terminal
vg200(config)# mgcp ip-tos precedence 5
VG200(config)# end
vg200(config)# voice-port x/x/x timing digit <50 - 500> milliseconds
For information on caveats in Cisco IOS Release 12.1(3)T, refer to Caveats for Cisco IOS Release 12.1.3(T), which lists severity 1 and 2 caveats for Cisco IOS Release 12.1.3(T).

The Cisco IOS software documentation set consists of the Cisco IOS configuration guides, Cisco IOS command references, and several other supporting documents which are shipped with your order in electronic form on the Documentation CD-ROM—unless you specifically ordered the printed versions.
Each module in the Cisco IOS documentation set consists of two books: a configuration guide and a corresponding command reference. Chapters in a configuration guide describe protocols, configuration tasks, Cisco IOS software functionality, and contain comprehensive configuration examples. Chapters in a command reference provide complete command syntax information. Use each configuration guide with its corresponding command reference.
On CCO and the Documentation CD-ROM, two master hot-linked documents provide information for the Cisco IOS software documentation set.
