Description of the Release

Cisco IOS® Software Release 12.1(2)XF is a short-lived release (XED) based on 12.1(2)T. It has been optimized to provide enhanced voice and voice applications for the Cisco 800 series of router (811 & 813), which targets small office and home office (SOHO) market. Another major addition to this code is the support of the Japanese INS-NET-64 switch standard. This makes it possible to support more features including Japanese caller ID display.

Product and Feature Support

Major New Features

Platforms/Images

• Japanese INS-NET-64

• Call Blocking on Caller ID

• Local Call Waiting (The user has the option to place the current call on hold by pressing flash key, connect to the incoming call, and then switch back to the current call)

• E Ya Yo (This feature allows an outgoing call's caller ID to be invisible to the receiving device. It is activated by dialing the prefix "184" specified in the NTT user manual before dialing the receiving device's number)

• Voice Warp/Voice Select Warp (This feature- NTT defined- is supported only when the Japanese INS-NET-64 Switch is connected to the router.)

• Nariwake (This feature allows mantis platform to register multiple Caller ID numbers with the ISDN (NTT INS-NET-64) switch based on router's local directory numbers. When calls are presented to the NTT Switch with a Caller ID identified on the list of registered numbers, the NTT switch will send a message to the mantis platform to notify the router that it should provide a distinctive ring to its telephone port to which the local directory number just called will be routed)

• Trouble Call Blocking
• I Number (allows several terminal devices to be used with one subscriber line)

Note: Most of the above features are activated ONLY when the global command "pots country JP" is configured in the router.
