Cisco Cisco IOS Software Release 12.2(2)XJ

This section describes possibly unexpected behavior by Release 12.2(2)XJ. Only severity 1 through 3 
caveats are included.

When using a Cisco 1750 router, a VIC-2DID card in the FXS mode, connected to a VIC-2FXO-M1 or 
a VIC-2FXO-M2, does not receive Caller ID information. The workaround is to enter ring number 4 as 
part of the voice port configuration on the VIC-2FXO-M1 card or the VIC-2FXO-M2 card.

When a 10-BaseT WIC is in Slot 1 and voice traffic is passing through two 10-BaseT WIC interfaces, a 
high call failure rate occurs. To work around this problem, place the 10-Base-T WIC in Slot 0 and place 
a Serial 2T card in Slot 1.

Small packets (smaller than 256 bytes per packet) have low performance when traffic streams go through 
both the Fast Ethernet port and two 10 BaseT WICs.

Sporadic and spurious memory-access messages might appear on a Cisco 1750, Cisco 1751 or 
Cisco 1751-V router running voice images. However, these messages do not affect router functionality.

The following sections describe the documentation available for the Cisco 1700 series routers. Typically, 
these documents consist of hardware and software installation guides, Cisco IOS configuration and 
command references, system error messages, feature modules, and other documents. Documentation is 
available as printed manuals or electronic documents, except for feature modules, which are available 
online on Cisco.com and the Documentation CD-ROM.
