Configuring Cisco TelePresence WebEx OneTouch on Cisco Unified Communications Manager

Revised: March, 2011, OL-21352-01

Note Cisco Unified CM must be running firmware 7.x or a later release with MIDlets software configured to use Cisco WebEx features.

You must also be running CTS software release 1.7.0 or a later release on the CTS, CTS-Manager, and CTMS.

Contents

To begin using Cisco TelePresence WebEx OneTouch on your Cisco TelePresence System (CTS), you must configure the Cisco Unified Communications Manager (Cisco Unified CM).

This chapter describes the following tasks:

•Defining a Route Pattern for Cisco WebEx

•Configuring the Room Name for the Cisco WebEx Participant List

Defining a Route Pattern for Cisco WebEx

As part of your Cisco WebEx configuration, you must add a route pattern for the Cisco WebEx audio number and point it to the Cisco TelePresence Multipoint Switch (CTMS) SIP trunk.

For Cisco WebEx meetings, the Cisco WebEx system automatically dials into the CTMS in order to bridge the audio between Cisco TelePresence and Cisco WebEx participants. The number that the Cisco WebEx system dials is defined in the CTMS configuration (see Configuring Cisco WebEx Details in CTMS). This number must be reachable from the PSTN, and requires that a route pattern be defined for it in the Cisco Unified Communications Manager route pattern list, which you will do in this chapter.

Note The route pattern MUST have the "Called Party Transform Mask" configured to expand the 5 digit [PSTN] number back to its full format.

The Called Party Transform Mask field enables the Cisco Unified CM system to modify the called number that is sent in the SIP Invite message. Calls from outside PSTN trunks often present the incoming call with a truncated destination number. For example, a PSTN call to 1-408-555-1212 might be truncated by the telephony service provider to 5-1212. The Called Party Transform Mask allows a Cisco Unified CM administrator to restore this number to the full dialed number string.

The CTMS will attempt to match the number found in the incoming SIP Invite, with the number that was configured to be used by Cisco WebEx when it calls the CTMS at meeting start time. The two numbers must match exactly, as CTMS does not understand any sort of number truncation or expansion.

To ensure that these numbers match exactly, the number configured in CTMS to be used when Cisco WebEx dials to CTMS should also be configured in the transform mask. This will ensure the number in the SIP "To:" field exactly matches the number that the CTMS is expecting. The CTMS will then be able to determine whether this call is for the Cisco WebEx audio connection.

Procedure

To define a route pattern for Cisco WebEx that points to your SIP trunk:

Step 1 Log in to the Cisco Unified Communications Manager Administration interface.

Step 2 Choose Call Routing > Route/Hunt > Route Pattern. The Find and List Route Patterns window appears.

Step 3 Click Add New. The Route Pattern Configuration window appears.

Step 4 In the Pattern Definition field, enter your Cisco WebEx audio dial-in number.

Step 5 Select the CTMS SIP trunk definition from the Gateway/Route List drop-down menu.

Step 6 In the Called Party Transform Mask field, enter the CTMS Dial In Number that you configured in Configuring the Cisco WebEx Dial In Number field in the CTMS Administration interface (see Configuring Cisco WebEx Details in CTMS). Observe the following requirements:

a. Enter your country code. For example, "1."

b. Enter the 10-digit callback number that was configured in the CTMS WebEx settings with the area code first. For example, "4085551234."

Note This number must exactly match the number that was entered into the CTMS Dial In Number field.

Step 7 Leave the default values in all other fields on the Route Pattern Configuration page.

Step 8 Click Save.

Step 9 Proceed to Configuring the Room Name for the Cisco WebEx Participant List.

Configuring the Room Name for the Cisco WebEx Participant List

Manage the TFTP profile for the Cisco TelePresence endpoint by configuring the TFTP profile meeting room name so that the room name appears on the Cisco WebEx Participant List.

To configure the room name:

Step 1 If you have not already done so, log in to the Cisco Unified CM Administration interface.

Step 2 From the Device drop-down menu, select Phone. The Find and List Phones Page appears containing a list of configured phones.

Tip If a list of configured phones is not displayed, click the plus sign (+) under Find and List Phones. Enter your search text in the Find field.

Step 3 On the Find and List Phones Page, click to select the associated codec for your phone. The codec Device Profile page for that device appears.

Step 4 In the Association Information box on the left side of the codec Device Profile page, click the associated directory number. For example, Line [1] - 23456 (no partition).

Tip Use the device MAC address to help you determine which line to select. The MAC address is also used as a device number for the settings in the Directory Number Configuration window.

The Directory Number Information page appears.

Step 5 Scroll down to Line 1 on Device SEPXXXXXXXXXXXX.

Step 6 Enter your room name in the Display (Internal Caller ID) fields, as shown in Figure 4-1.

Step 7 Leave the default value in all remaining fields.

Step 8 Click Save to save your settings.

Tip Cisco TelePresence WebEx OneTouch configuration is not complete until you configure Cisco TelePresence Manager and the Cisco WebEx Site Administration account.
