Use show voice dsp group all command to verify DSP resource allocation.

Note: Each 5510 DSP has 240 Credits. This work-around cannot be implemented if the router has 
only one PVDM2-16 which has only one DSP.

CSCsg48183: Unforeseen ARP request send from all interfaces

A router may unexpectedly send an ARP request from all its active interfaces to the nexthop 

of the network of an SNMP server.

This symptom is observed on a Cisco router that has the snmp-server host command enabled 

after any of the following actions occur:

Reload the router.

A switchover of the active RP occurs.

Enter the redundancy force-switchover main-cpu command.

There is no workaround.

CSCsg57228: IPS5.0: c871 reloads using IOS-S222 package file

Router crashes loading the IOS signature package file

Appeared to happen the most on the Cisco 871 and Cisco 2600 platforms.

There is no workaround.

CSCsg68199: Trunk DN offhook is not propagated to a phone already in dial out mode

Two IP Phones A and B are registered with Cisco CallManager Express; these phones share 

two trunk DNs 1 & 2. If Phone-A goes offhook on DN-1 and Phone-B immediately goes offhook on 
DN-2. This condition should show the DN-2 button on Phone-A as busy which is not happening.

This happens only when trunk DNs are used and the they go offhook in quick succession on 

different phones and are in dialing mode.

There is no workaround.
