Defect Number: CSCed24485
Severity Level: 2
Component: sw-phone-7912
Headline: 7912 drops incoming packets
Symptom: Bad quality when calling from a Cisco IP Phone 7912F to a third-party IP voice messaging system. The audio coming from the voice messaging system.
Condition: The Cisco IP Phone 7912G is running firmware image version CP7912010200SCCP031023A. The voice messaging system is Voicemail Performance Solutions Vision server.
Workaround: None.
Known Defects

You can search for more information about these and other known caveats using the Cisco bug tracking system tool, called Bug Navigator II.
To access Bug Navigator II, perform one of the following actions:

Defect Number: CSCed22747
Severity Level: 2
Component: sw-phone-7912
Headline: Cannot support switch that repeats packets on the same switch port
Symptom: For example, the voice VLAN is set to 105 and the native VLAN is set to 5. However, every time a Cisco IP Phone model 7905G or 7912G sends out a packet in voice VLAN 105 (the VLAN tagged with the VLAN ID 105), the same packet is repeated by the switch on the same switch port through which the phone sent the packets. The repeated packet is VLAN tagged with VLAN ID 1, with the same source and destination MAC address. When this situation occurs, the Ethernet chip on the phone processes the packet as if it were a different device with the same MAC address, which causes problems.
Condition: Cisco IP Phone model 7905G or 7912G.
Workaround: This situation is a result of a hardware limitation of the Cisco IP Phone model 7905G/7912G. The only solution is to not repeat the packets on the same switch port. One workaround is to disallow VLAN 1 on the switch port by making the following settings for the switch:
switchport trunk allowed vlan add 105
switchport trunk allowed vlan add 5
Defect Number: CSCuk46104
Severity Level: 3
Component: sw-phone-7905
Headline: Voice quality (MOS) too low for G.729a calls
Symptom: Transmitted voice quality is poor from the affected device. Received voice quality is good if the remote device is not a Cisco IP Phone model 7902G, 7905G, 7912G, or Analog Telephone Adaptor. Actual PESQ-LQ derived MOS score recorded is below 3.5. Expected level should be 3.7.
Condition: G.729a calls involving the Cisco IP Phone 7902G, 7905G, 7912G, and Analog Telephone Adaptor
Workaround: Use G.711 codec where possible.

Opening a TAC Case
Using the online TAC Case Open Tool is the fastest way to open P3 and P4 cases. (P3 and P4 cases are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using the recommended resources, your case will be assigned to a Cisco TAC engineer. The online TAC Case Open Tool is located at this URL:
http://www.cisco.com/tac/caseopen
For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.
To open a case by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
