SIP-to-SIP Supplementary Services for Session Border Controller
The SIP-to-SIP Supplementary Services for Session Border Controller (SBC) feature enhances terminating and reoriginating of signaling and media between VoIP and video networks by supporting the following features:
- IP Address-Hiding in all Session Initiation Protocol (SIP) messages including supplementary services
- Media Flow Around
- Hosted Network Address Translation (NAT) Traversal for SIP
- Support on Cisco AS5350XM and Cisco AS5400XM platforms
- SIP-to-SIP Supplementary services using REFER/3xx method.
The following features of SIP-to-SIP Supplementary services using REFER/3xx method are enabled by default:
Digital Signal Processors (DSPs) and SIP Call Hold/Resume
Digital Signal Processors (DSPs) generate and transmit Real-time Transport Protocol (RTP) media packets from a source to a destination address during a SIP call session. However, when a SIP call is put on hold, DSPs stop generating the RTP media packets and resumes generating and transmitting the RTP media packets after the SIP call is resumed. This ensures that the RTP sequence number is continuous from the time of origin until the end of the SIP call.
How to Configure SIP-to-SIP Supplementary Services for Session Border Controller
To configure the SIP-to-SIP Supplementary Services for Session Border Controller feature, see the "SIP-to-SIP Connections on a Cisco Unified Border Element" chapter in the Cisco Unified Border Element Configuration Guide.
