• X.509 Subject Name— Enter your certificate name if you want CUCM to communicate with Cisco WebEx Meetings Server using TLS.

  Note

  If you want CUCM to communicate with Cisco WebEx Meetings Server using TLS, a different Cisco WebEx Meetings Server system cannot share the same SIP Trunk Security Profile because each system must have a different certificate. Obtain the Cisco WebEx Meetings Server certificate name from the Administration site. For more information refer to "Managing Certificates" in the Administration Guide.

• Incoming Port— Enter 5060 if you want CUCM to communicate with Cisco WebEx Meetings Server using UDP/TCP. Enter 5061 if you want CUCM communicates Cisco WebEx Meetings Server using TLS.

1. Sign in to the Cisco WebEx Meetings Server Administration site.
2. Select Settings > Security > Certificates.
3. Copy the certificate name from the SSL Certificate section.
4. Select More Options > Export SSL certificate.
5. Save your certificate to your local hard drive.

Wait for your system to indicate "Success: Certificate Uploaded."

This is the last, self-signed certificate from the verification chain, which is used to verify the CallManager.pem certificate.

Wait for your system to indicate "Success: Certificate Uploaded."

• Device Name—Enter a name for the SIP trunk.
• Device Pool—Select an appropriate device pool from the drop-down menu. To determine which Cisco Unified Communications Manager Group has been configured on that device pool, select System > Device Pool menu. To verify which Cisco Unified Communications Managers are part of this group, select System > Cisco Unified CM Group.

  Note

  Record the IP addresses of the primary and secondary server. You will enter these IP addresses when you configure your audio settings in Cisco WebEx Meetings Server. See "Configuring Your Audio Settings for the First Time" in the Administration Guide for more details. See Cisco WebEx Meetings Server Install and Upgrade Guides.

• Destination Address—Enter your load balance point IPv4 address. Refer to the SIP Configuration table on your Administration Site Audio page the IP address.
• Destination Address IPv6—Enter your load balance point IPv6 address if you want to enable IPv6 between CUCM and Cisco WebEx Meetings Server.
• Destination Port—Enter 5060 if you want CUCM to communicate with Cisco WebEx Meetings Server using UDP/TCP. Enter 5061 if you want CUCM to communicate with Cisco WebEx Meetings Server using TLS.
• SIP Trunk Security Profile—Select your load balance point's security profile from the drop-down menu.
• SIP Profile—Select Standard SIP Profile if you want CUCM to communicate with Cisco WebEx Meetings Server using UDP/TCP. Select TLS SIP Profile if you want CUCM to communicate with Cisco WebEx Meetings Server using TLS. Select IPv6 SIP Profile if you want to enable IPv6 between CUCM and Cisco WebEx Meetings Server.
• Calling Search Space—Select a Calling Search Space that can call the phone numbers and route patterns configured in CUCM that you want Cisco WebEx Meetings Server to call out to. Select Call Routing > Class of Control > Calling Search Space. A calling search space consists of an ordered list of route partitions that are typically assigned to devices or route patterns. Calling search spaces determine the partitions that calling devices search when they are attempting to complete a call. For more information, refer to "Calling Search Space Configuration" in the Cisco Unified Communications Manager Administration Guide or "Partitions and Calling Search Spaces" in the Cisco Unified Communications Manager System Guide.
• Rerouting Calling Search Space—Select a Calling Search Space that contains the route partition that is configured for the SIP route pattern from the section below, "Configuring a SIP Route Pattern." If this is set to < None >, then this will only be able to route calls to route patterns with a route partition set to < None >, so the SIP route pattern will need to have the route partition set to < None >. This configuration is necessary to enter meetings in Cisco WebEx Meetings Server. For more information, refer to "Calling Search Space Configuration" in the Cisco Unified Communications Manager Administration Guide or "Partitions and Calling Search Spaces" in the Cisco Unified Communications Manager System Guide for more information.

You must reset the SIP trunk to complete your configuration.
