Information About Cisco UBE RTCP Voice Pass-Through for IPv6
Cisco Unified Border Element in VoIPv6
The Cisco Unified Border Element (UBE) feature adds IPv6 capability to existing VoIP features. This feature adds dual-stack support on voice gateways and MTP, IPv6 support for SIP trunks, and support for SCCP-controlled analog voice gateways. Real-time control protocol (RTCP) pass-through and T.38 fax over IPv6 have also been added to Cisco UBE.
RTCP Pass-Through
IPv4 and IPv6 addresses embedded within RTCP packets (for example, RTCP CNAME) are passed on to Cisco UBE without being masked. These addresses are masked on the Cisco UBE ASR 1000.
The Cisco UBE ASR 1000 does not support printing of RTCP debugs.
RTCP is passed through by default. No configuration is required for RTCP pass-through.
How to Configure Cisco UBE RTCP Voice Pass-Through for IPv6
Configuring IPv6 Support for Cisco UBE
Perform this task to configure IPv6 support for Cisco UBE.
 Note | In Cisco UBE, IPv4-only and IPv6-only modes are not supported when endpoints are dual-stack. In this case, Cisco UBE must also be configured in dual-stack mode. > |
