From the Enable IPv6 drop-down list, choose True.

Step 3

From the IP Addressing Mode Preference for Media drop-down list, choose IPv6.

Step 4

From the IP Addressing Mode Preference for Signaling drop-down list, choose IPv6.

Step 5

From the Allow Auto-configuration for Phones drop-down list, choose Off.

Step 6

Save your changes.

Add a Common Device Configuration Profile in Unified Communications Manager

In an IPv6-enabled environment, you may have both IPv4 and IPv6 devices.

Perform the following procedure to add an IPv4, IPv6, or dual stack common device configuration profile in Unified Communications Manager.

Procedure

Step 1

From Cisco Unified CM Administration, choose Device > Device Settings > Common Device Configuration.

Step 2

Click Add New and enter the name of the new common device configuration profile.

Step 3

From the IP Addressing Mode drop-down list:

  • To add an IPv6 common device configuration profile in Unified Communications Manager, choose IPv6 only.
  • To add an IPv4 common device configuration profile in Unified Communications Manager, choose IPv4 only.
  • To add a dual stack common device configuration profile in Unified Communications Manager, choose IPv4 and IPv6. Then choose IPv4 from the IP Addressing Mode Preference for Signaling drop-down list.

Step 4

Save your changes.

Associate the Common Device Configuration Profile with Gateway Trunk

Perform the following procedure to associate the common device configuration profile with the Gateway trunk. This procedure applies to the Ingress Gateway.

Procedure

Step 1

From Cisco Unified CM Administration, choose Device > Trunk.

Step 2

Click Find.

Choose the trunk profile that you want to view.

Step 3

From the Common Device Configuration drop-down list:

  • To associate the IPv6 common device configuration profile with the Gateway trunk, choose the IPv6 common device configuration profile.
  • To associate the IPv4 common device configuration profile with the Gateway trunk, choose the IPv4 common device configuration profile.

Note

 

Unified CM gateway trunk supports only an IPv4 or IPv6 trunk. You cannot associate a dual stack common device configuration profile to a Unified CM gateway trunk.

Step 4

Enter the IPv6 address in the Destination Address IPv6 field.

Note

 

Unified CM to Gateway trunk supports only standard SIP Profile and does not support ANAT enabled dual-stack SIP trunk.

Step 5

Save your changes.

Associate the Common Device Configuration Profile with an IPv4 or IPv6 Phone

Procedure

Step 1

From Cisco Unified CM Administration, choose Device > Phone.

Step 2

Click Find.

Choose the trunk profile that you want to view.

Step 3

From the Common Device Configuration drop-down list: choose the IPv6 common device configuration profile.

  • To associate the IPv6 common device configuration profile to an IPv6 phone, choose the IPv6 common device configuration profile.
  • To associate the IPv4 common device configuration profile to an IPv4 phone, choose the IPv4 common device configuration profle.

Step 4

Save your changes.

Configure SIP trunk from Unified Communications Manager to Unified CVP

The following sections describe the steps to configure the SIP trunk from Unified Communications Manager to Unified CVP.

Add a SIP Profile in Unified CM

This option allows a dual-stack SIP trunk to offer both IPv4 and IPv6 media. Perform this procedure for IPv6-enabled deployments only.

Procedure

Step 1

From Cisco Unified CM Administration, choose Device > Device Settings > SIP Profile.

Step 2

Click Add New and enter the name of the SIP profile.

Step 3

Check the Enable ANAT check box on the SIP Profile.

Step 4

Save your changes.

Associate the Dual Stack Common Device Configuration Profile with SIP Trunk

You only need to perform this procedure if you have an IPv6 enabled deployment.

Procedure

Step 1

From Cisco Unified CM Administration, choose Device > Trunk.

Step 2

Click Find. Choose the trunk profile that you want to view.

Step 3

From the Common Device Configuration drop-down list, choose the Dual Stack Common Device Configuration Profile.

Note

 

For more information on how to add a Dual Stack Common Device Configuration Profile, see Add a Common Device Configuration Profile in Unified Communications Manager.

Step 4

Save your change.

Gateway Configuration

Configure an Interface to Support IPv6 Protocol Stack

This procedure applies to both the Ingress and the VXML gateway.

Procedure

Configure the following on the Gateway: 


>Enable
>configure terminal
>interface type number
>ipv6 address{ ipv6-address / prefix-length | prefix-name sub-bits / prefix-length}
>ipv6 enable

Enable ANAT in Ingress Gateway

Procedure

Configure the following on the Gateway:

  
>conf t
>voice service voip
>SIP
>ANAT
>bind control source-interface GigabitEthernet0/2
>bind media source-interface GigabitEthernet0/2

Enable Dual Stack in the Ingress Gateway

Procedure

Configure the following on the Gateway:


>conf t
>sip-ua
>protocol mode dual-stack preference ipv6

Transcoder Configuration in Unified CM and IOS Gateway

A transcoder is required in the following scenarios

  • An agent logged in to an IPv6 endpoint needs to send or receive transfers from an agent logged in to an IPv4 endpoint.

  • An agent logged in to an IPv6 endpoint needs to connect to a VXML Gateway for self service.

  • A multicodec scenario to convert a stream from a G.711 codec to G.729 codec.

For more information about transcoder configuration in Unified Communications Manager and gateway, see the section "Configure Transcoders and Media Termination Points" in the System Configuration Guide for Cisco Unified Communications Manager at https://www.cisco.com/c/en/us/support/unified-communications/unified-communications-manager-callmanager/products-installation-and-configuration-guides-list.html.

Configure the CVP Call Server Dial Peers in Ingress Gateway

The Ingress Gateway to Unified CVP outbound dial peer configuration uses the IPv4 address of Unified CVP as the session target.
