MWIs for Extensions on a Non-Integrated Phone System

MWIs for Extensions on a Non-Integrated Phone System

---

Cisco Unity can activate MWIs on a phone system that is not integrated with Cisco Unity and that is not part of a two phone system integration (referred to here as a non-integrated phone system). MWI activation requests are sent through an RS-232 serial cable.

For this method, you must set up:

•A trunk connection between Cisco Unified Communications Manager and the non-integrated phone system through a gateway.

•The unique subscriber extensions on the non-integrated phone system to forward on no answer to the corresponding phantom extensions on Cisco Unified CM.

•The Switch.ini file (phone system configuration file) to enable Cisco Unity access through the serial cable for turning alternate MWIs on and off.

•An RS-232 serial cable between a Cisco Unity serial port and the non-integrated phone system serial port to send alternate MWI activation requests.

•The Cisco Unity serial configuration file, if the non-integrated phone system uses a serial configuration different from the default serial configuration used by Cisco Unity.

Figure B-1 shows the connections via a serial cable between a Cisco Unified CM integration and a non-integrated phone system.

Calls to subscribers that come from the non-integrated phone system are routed through the gateway to Cisco Unified CM.

Setting Up MWIs for Extensions on a Non-Integrated Phone System

To set up MWIs for extensions on a non-integrated phone system, do the following applicable procedures.

To Set Up MWIs on a Non-Integrated Phone System

---

Step 1 Set up a trunk connection between the non-integrated phone system and Cisco Unified CM through the gateway.

Step 2 In Cisco Unity Administrator, set up the subscriber for the phantom extension, making use of the subscriber information from the corresponding extension on the non-integrated phone system, including the following settings:

•On the Subscriber > Profile page for the subscriber, in the Extension field, enter the corresponding extension on the non-integrated phone system.

•On the Subscriber > Call Transfer page for the subscriber, under Transfer Incoming Calls, click No.

•On the Subscriber > Messages page for the subscriber, confirm that the Use MWI for Message Notification check box is checked.

•On the Subscriber > Messages page for the subscriber, under MWI Extensions, delete the "X" and enter ZX.

Step 3 In Cisco Unity Administrator, click the Save icon.

To Revise the Switch.ini File

---

Step 1 On the Windows Start menu, click Programs > Cisco Unity > Manage Integrations. UTIM appears.

Step 2 In the left pane of the UTIM window, click the Cisco Unified CM integration, and click the Properties node. The Properties tab appears in the right pane of the UTIM window.

Step 3 Note the name of the Switch.ini file that appears in the Configuration File field.

Step 4 Exit UTIM.

Step 5 On the Windows Start menu, click Programs > Accessories > Notepad. The Notepad window appears.

Step 6 On the File menu, click Open.

Step 7 In the Open window, navigate to the CommServer\IntLib directory, and double-click the name of the Switch.ini file you noted in Step 3.

Step 8 Add a new section at the end of the file to contain the following lines. For detailed information about the settings, see Table B-1.

[Alternate MWI]

Active=Yes

Digit=Z

MWIType=Serial

SerialConfiguration=<if applicable, the type of serial 

configuration for the connection>

Table B-1 Alternate MWI Settings in the Switch.ini File 

Line	Setting
Active	Enter Yes to enable alternate MWIs or No to disable alternate MWIs.
Digit	Enter Z to represent the LampOn and LampOff digits in the MWI Extensions field on the Subscriber > Subscriber > Messages page.
MWIType	Enter Serial.
SerialConfiguration	If the MWIType field is Serial, enter the type of serial configuration: •SMDI (for most serial connections) •MCI (only for NEC NEAX phone systems) •Inte (only for Intecom E14 Millennium phone systems) •Eric (only for Ericsson MD-110 phone systems)

Step 9 Save the file, and exit Notepad.

---

Do the following procedure if the serial configuration used by the non-integrated phone system is different from the default serial configuration that Cisco Unity uses.

To Revise the Cisco Unity Serial Configuration File

---

Step 1 On the Windows Start menu, click Programs > Accessories > Notepad. The Notepad window appears.

Step 2 On the File menu, click Open.

Step 3 In the Open window, navigate to the CommServer\IntLib directory, and double-click the file corresponding to the serial configuration you are using to activate alternate MWIs:

•Avsmdi.avd

•Avmci.avd

•Avinte.avd

•Averic.avd

Step 4 Under the [Configuration] divider, revise the settings to match the configuration required by the non-integrated phone system. Refer to the phone system and its documentation for this information.

Step 5 Save the file, and exit Notepad.
