Interworking of Secure RTP calls for SIP and H.323

Cisco IOS XE
Release 3.1S

This feature provides an option for a Secure RTP (SRTP) call to be connected from H.323 to SIP and from SIP to SIP. Additionally, this feature extends SRTP fallback support from the Cisco IOS voice gateway to the Cisco Unified Border Element.

This feature uses no new or modified commands.

Modem passthrough

Cisco IOS XE
Release 3.1S

The SIP-to-SIP Extended Feature Functionality for Session Border Controllers (SBCs) enables the SIP-to-SIP functionality to conform with RFC 3261 to interoperate with SIP User Agents (UAs).

This feature uses no new or modified commands.

Negotiation of an Audio Codec from a List of Codecs on Each Leg of a SIP-to-SIP Call on the Cisco Unified Border Element

Cisco IOS XE Release 2.5

The Support for Negotiation of an Audio Codec from a List of Codecs on Each Leg of a SIP-to-SIP Call on the Cisco Unified Border Element feature supports negotiation of an audio codec using the Voice Class Codec and Codec Transparent infrastructure on the Cisco UBE.

The following command was introduced or modified: voice-class codec (dial peer).

RTP Media Loopback for SIP Calls

Cisco IOS XE
Release 3.3S

RTP packets are looped back toward the source when the RTP Media Loopback for SIP Calls feature is configured on a dial peer. SIP RTP media loopback helps in verifying the media path between the device originating the call and the intermediate device.

The following commands were introduced or modified: None.

SIP Parameter Modification

Cisco IOS XE Release 2.5

Allows users to change the standard SIP messages sent from the Cisco SIP stack for better interworking with different SIP entities.

This feature introduces or modifies the following commands: voice class sip-profiles, voice-class sip profiles

SIP SRTP Fallback to Nonsecure RTP

Cisco IOS XE
Release 3.1S

The SIP SRTP Fallback to Nonsecure RTP feature enables a Cisco IOS Session Initiation Protocol (SIP) gateway to fall back from SRTP to RTP by accepting or sending an RTP/AVP(RTP) profile in response to an RTP/SAVP(SRTP) profile. This feature also allows inbound and outbound SRTP calls with nonsecure SIP signaling schemes (such as SIP URL) and provides the administrator the flexibility to configure TLS, IPsec, or any other security mechanism used in the lower layers for secure signaling of crypto attributes.
