The Support for Dynamic Payload Type Interworking for DTMF and Codec Packets for SIP-to-SIP Calls feature provides dynamic payload type interworking for DTMF and codec packets for SIP-to-SIP calls.
The following commands were introduced or modified: asymmetric payload and voice-class sip asymmetric payload.
Cisco IOS XE Release 2.5
The iLBC is a standard, high-complexity speech codec suitable for robust voice communication over IP. The iLBC has built-in error correction functionality that helps the codec perform in networks with high-packet loss. This codec is supported on both Session Initiation Protocol (SIP) and H.323.
The following commands were introduced or modified: codec ilbc, codec preference, and rtp payload-type.
Interworking Between RSVP Capable and RSVP Incapable Networks
Cisco IOS XE Release 3.1S
The Support for Interworking Between RSVP Capable and RSVP Incapable Networks feature provides precondition-based RSVP support for basic audio call and supplementary services on the Cisco UBE.
The following commands were introduced or modified: acc-qos, ip qos defending-priority, ip qos dscp, ip qos policy-locator, ip qos preemption-priority, req-qos, voice-class sip rsvp-fail-policy,
Cisco IOS XE
Release 3.1SThis 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.
Cisco IOS XE
Release 3.1SThe 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.
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).
Cisco IOS XE
Release 3.3SRTP 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.
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
Cisco IOS XE
Release 3.1SThe 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.
The following command was modified by this feature: srtp, srtp negotiate, and voice-class sip srtp negotiate
Cisco IOS XE
Release 3.1SThis feature provides the capability for media packets to pass directly between endpoints without the intervention of the Cisco UBE.
The following command was modified by this feature: media
Cisco IOS XE Release 3.3S
Cisco IOS XE
Release 3.1SThis feature allows the Cisco Unified Border Element (Enterprise) to generate SIP INVITES that include SDP lines for both Voice and Voice media paths.
SIP—Ability to Send a SIP Registration Message on a Border Element
Cisco IOS XE Release 2.5
Provides the ability to send a SIP Registration Message from Cisco Unified Border Element.
The following command was modified: credentials (SIP UA)
Cisco IOS XE Release 2.5
The SIP—INFO Method for DTMF Tone Generation feature uses the Session Initiation Protocol (SIP) INFO method to generate dual-tone multifrequency (DTMF) tones on the telephony call leg. SIP methods, or request message types, request a specific action be taken by another user agent (UA) or proxy server. The SIP INFO message is sent along the signaling path of the call.
The following command was introduced: show sip-ua.
Cisco IOS XE Release 2.5
Implements capabilities to the SIP gateway Cisco IOS stack involving user-agent handling of messages, handling of unsolicited messages, support for outbound delayed media, and SIP headers and content in requests and responses.
