System Requirements

The Cisco Unity server must be running Cisco Unity version 2.4(6.135), 3.0(1), or 3.0(2).

An account with Local Administrator privileges must be used to upgrade or install the AV-Cisco TSP. Otherwise, no Cisco Unity ports will be available after the upgrade or installation.

Microsoft® Windows® 2000 Service Pack 1 or Service Pack 2 must already be installed on the Cisco Unity server, if it is running Windows 2000. Otherwise, the AV-Cisco TSP cannot be installed.

If you are installing the AV-Cisco TSP for the first time, you need to add Cisco uOne ports in Cisco CallManager Administration, then configure the AV-Cisco TSP to connect to those ports. Refer to the Cisco CallManager 3.0 Integration Guide (available on the Cisco Unity Documentation compact disc and on Cisco.com at http://www.cisco.com/univercd/cc/td/doc/product/voice/c_unity/unity30/integuid/callma30/index.htm).

Step 4 When the file has downloaded, navigate to the file and double-click it.

Step 5 Accept the directory to which the file will be unzipped, or indicate the directory of your choice.


Installing the AV-Cisco TSP

The following three sections apply to installation of the AV-Cisco TSP. However, the first two sections apply only in certain situations:

Do the "Adding Cisco Unity Ports in Cisco CallManager" section only if the number of Cisco Unity ports is changing.

Do the "Removing Call Routing Rules That Were Changed or Added as a Workaround" section only if the Cisco Unity server is running AV-Cisco TSP version 1.0(0.28) and if you used a workaround for caveat number CSCae08089.

Adding Cisco Unity Ports in Cisco CallManager

If the number of Cisco Unity ports is changing, you need to add a uOne port to Cisco CallManager for each port that you are connecting to Cisco Unity.

Refer to the three procedures in the "Setting Up Cisco CallManager" section in the "Cisco CallManager 3.0 Integration" chapter of the Cisco CallManager 3.0 Integration Guide (available on the Cisco Unity Documentation compact disc and on Cisco.com at http://www.cisco.com/univercd/cc/td/doc/product/voice/c_unity/unity30/integuid/callma30/index.htm).


Caution uOne ports and phones must be in the same calling search space, or the integration will not work.

Removing Call Routing Rules That Were Changed or Added as a Workaround

Do the procedures in this section if the Cisco Unity server is running AV-Cisco TSP version 1.0(0.28) and if you used one of the following workarounds for caveat number CSCae08089 (subscribers hear the opening greeting instead of the logon conversation if the first voice messaging port is in use):

Changed the default routing rules with AvRulerEditor.exe. This workaround was posted to Cisco Unity Online Support Forums, at http://avforums.isomedia.com/cgi-bin/wwwthreads.pl.

Added one or more routing rules that applied to calls forwarded from voice messaging ports and that sent forwarded calls to the subscriber logon conversation.

The routing rules must be reset to their default values (which deletes any non-default routing rules).

To locate valid routing rules


Step 1 In the Cisco Unity Administrator, go to Call Management > Call Routing > Forwarded Calls.

Step 2 Write down the settings for each non-default routing rule. (The default routing rules are Attempt Forward to Greeting and Default Call Handler.) If a routing rule has the following values in the Forwarding Station and Send Call To columns, it was added for the workaround and should not be recreated after you reset routing rules to their default values:

Forwarding Station

One or more of the ports assigned to Cisco Unity. This value may include the * (star) wildcard character.

Send Call To

Attempt Sign-In.



To reset routing rules to their default values and to delete non-default routing rules


Step 1 Browse to the Commserver directory, and double-click ConfigMgr.exe.

Step 2 In the ConfigMgr dialog box, click Browse, and browse to Commserver\Localize\DefaultConfiguration\<Language folder>.

Step 3 Double-click the file DefaultRules.dcs.

Step 4 Click Run Rules Configuration DCS Script.

Step 5 Click Run.

Step 6 When the message "Default rules configured successfully" appears, close the ConfigMgr dialog box. If any errors appeared while ConfigMgr.exe was running, call Cisco TAC.


To recreate valid routing rules


Step 1 In the Cisco Unity Administrator, go to Call Management > Call Routing > Forwarded Calls.

Step 2 Recreate the routing rules by using the values that you wrote down in the "To locate valid routing rules" procedure. For more information, see the Cisco Unity Administrator Online Documentation.


Installing AV-Cisco TSP Release 1.0(0.39)

Before you install AV-Cisco TSP Release 1.0(0.39) on the Cisco Unity server, you must remove any existing version of the TSP.

Caveats

This section describes only Severity 1 and 2 caveats.

If you have an account with Cisco.com, you can use Bug Navigator II to find caveats of any severity for any release. Bug Navigator II is available at the website http://www.cisco.com/support/bugtools/bugtool.shtml.

Open Caveats—Release 1.0(0.39)

There are no open caveats for the AV-Cisco TSP 1.0(0.39) release.

Resolved Caveats—Release 1.0(0.39)

Table 2 Release 1.0(0.39) Resolved Caveats

Caveat Number
Description

CSCdu66816

During Cisco Unity startup, not all ports register with Cisco CallManager.

Conditions:

A sniffer trace captured that Cisco CallManager terminates a TCP connection that was established between Cisco Unity and Cisco CallManager. Because the current AV-Cisco TSP cannot retry initializing the ports upon failure, the Cisco Unity server will come up with fewer voice messaging ports than the number for which it is configured.

CSCdv03145

MWIs fail to light due to socket connection problems. These socket connection problems prevent all ports from recovering, reregistering, and reconnecting to Cisco CallManager.

Conditions:

If Cisco Unity loses the socket connection, and Cisco CallManager notices that the connection is lost, when Cisco Unity reregisters after the network connection comes back, everything works fine.

However, if Cisco CallManager does not notice that the socket connection is lost, Cisco Unity will not recover correctly. In this case, when the network connection comes back and Cisco Unity reregisters, Cisco CallManager notes that the Cisco Unity port is reregistering on a different link, tries to register, and fails.

CSCdv17898

The AV-Cisco TSP does not support sending and receiving fourth-column DTMF tones (ABCD).

Conditions: These are required for AMIS.


Resolved Caveats—Release 1.0(0.36)

Table 3 Release 1.0(0.36) Resolved Caveats

Caveat Number
Description

CSCae07641

Voice packets and other network packets have equal priority on sites with a lot of traffic. This can result in poor voice quality on systems running Windows 2000.

CSCdu28067

Caller hears dead air when attempting a transfer to an invalid extension.

CSCdu29480

Timeout waiting for transfer to an invalid extension.

CSCdu30170

Supervised transfers fail intermittently, and the following error is logged in the event log:

Failure in Method CAvMiuLine::TransferComplete (eMIU_XFER COMPLETE_ REJECTED).

CSCdu46097

Timeout waiting for idle state on a supervised transfer.

CSCdu46310

MWI collision issues with the AV-Cisco TSP.

If ports are not dedicated to MWIs, then collisions may occur, and sometimes they will not be handled correctly by the AV-Cisco TSP and/or the MIU.

See the "Avoiding Collisions Between MWIs and Incoming Calls" section for related information.

CSCdu57510

Intermittent errors in the event log from AvMiu_MC: Timed-out waiting for LINECALLSTATE_CONNECTED after lineAnswer.

CSCdu63559

Under heavy call load, an MWI notification sent to Cisco CallManager may not be processed in a timely fashion.

CSCdu68598

Supervised transfer takes about 1 minute to complete, resulting in about 30 seconds of dead air before the subscriber greeting is played.


Resolved Caveats—Release 1.0(0.32)

Table 4 Release 1.0(0.32) Resolved Caveats

Caveat Number
Description

CSCae07656

The AV-Cisco TSP needs configurable logging.

CSCae07923

Ring no answer may be reported as disconnect.

Cisco Unity 2.4(6.102) using AV-Cisco TSP 1.0(0.28) to connect to Cisco CallManager version 3.0(x) does not properly report RNA conditions.

CSCae07925

An outgoing call through the gateway is set to connected while the call is still alerting.

Message notification over an analog gateway to external phones, and supervised transfers in a dual phone system environment (including any call-hold or call-screening) display a connected state when no connection has been made.

CSCae07968

Pager notification fails to send all digits through an analog gateway.

If you use subscriber message notification settings specifying additional digits for notification over an analog gateway, the last digit of a string of more than eight numbers may not be received by the notification device (for example, a pager or cell phone).

CSCae08050

Supervised transfers fail.

When attempting a supervised transfer, Cisco Unity initiates the transfer, dials out to the extension, and after the specified wait-for rings, disconnects and goes idle, without connecting the calling party. The port remains locked until the calling party hangs up.

CSCae08086

The AV-Cisco TSP uses CalledParty instead of OriginalCalledParty.

When Cisco CallManager forwards a Cisco Unity subscriber call to the next available uOne port, Cisco Unity may return an opening greeting rather than the expected subscriber sign-in prompt.

CSCae08089

Subscribers hear the opening greeting if the first voice messaging port is in use.

When Cisco CallManager forwards a Cisco Unity subscriber call to the next available uOne port, Cisco Unity may return an opening greeting rather than the expected subscriber sign-in prompt.

CSCae08090

Subscriber message notification settings are not recognized.

If you use subscriber message notification settings specifying repeat notification, the minutes set to wait between notification calls are disregarded.

CSCae08152

Supervised transfers to busy extensions fail.

When attempting a supervised transfer to a busy extension, Cisco Unity initiates the transfer, dials out to the extension, and after the specified wait-for rings, disconnects and goes idle, without connecting the calling party to the dialed party's voice mail. The port remains locked until the calling party hangs up.

CSCdu04699

Phone disconnection locks out Cisco Unity port.

During a call, if the line from a phone is disconnected (either by disconnecting the network cable or power of the phone), the port that call was on is locked out. The port does not clear until the AV-Cisco TSP is reset or Cisco Unity is restarted.

CSCdu17234

Cisco Unity stops answering calls on a voice messaging port.

This has been seen only on very high-traffic systems under extreme load. It occurs only when using AV-Cisco TSP versions 1.0(0.31) or 1.0(0.32) with Cisco Unity version 2.4(6.102).


Troubleshooting

For information on troubleshooting the AV-Cisco TSP and the phone system integration, refer to the Cisco CallManager 3.0 Integration Guide (available on the Cisco Unity Documentation compact disc and on Cisco.com at http://www.cisco.com/univercd/cc/td/doc/product/voice/c_unity/unity30/integuid/callma30/index.htm).

Documentation Update

Change—Release 1.0(0.36)

Avoiding Collisions Between MWIs and Incoming Calls

Collisions between MWIs and incoming calls are not possible when ports are dedicated to handle only MWIs or incoming calls.

Although all known collision problems are fixed in AV-Cisco TSP Release 1.0(0.36), there may be other collision issues that have not yet been discovered. Therefore, we recommend dedicated MWI ports.
