Product and Feature Support
|The Cisco IOS Software Release 12.1(3)XI will support the following:
Interworking Signaling Enhancements for H.323 VOIP:
AIM-VPN/BP, AIM-VPN/HP, NM-VPN/MP
- Interworking Signaling Enhancements for H.323 VOIP provides major fixes to provide proper signaling when signaling is passed between ISDN (Q.931) and H.323 CAS interfaces.
T.37/T.38 Fax Gateway
- AIM-VPN is a hardware Layer 3 (IPSec) encryption hardware processor on AIM and NM form-factors, for use in 26xx and 36xx routers. Encryption is based on the IRE CryptIC chip currently in development, and provides DES (56-bit) and Triple-DES (3DES 168-bit) encryption algorithms.
- The primary objective is to offer voice, fax relay, and fax store and forward on the same voice port. This initiative is also meant to achieve a closer integration of the voice and fax applications - providing the ability to dynamically switch from one application to another in the same call (IVR, voice, fax relay, fax store and forward). This level of flexibility is required to support the Unified Communications requirements expressed by our customers.
Multimedia Conference Manager with Voice Gateway image with RSVP to ATM SVC
- VIC-2BRI-NT/TE and MC3810-BVM4-NT/TE provides Network Side Basic Rate Interface (BRI) ISDN Voice for the 2600, 3600 & 3810
- Provides true PSTN tie & trunk line replacement using IP, Frame Relay or ATM as a transport mechanism for voice and fax
- Eliminates the need to reconfigure connected PABX?s BRI interfaces, purchase new PBX/PABX BRI interfaces or purchase completely new PBX/PABXs
- Allows enterprises to seamlessly migrate towards a single infrastructure Architecture for Voice, Video and Data
- Allows penetration into small and medium sized offices which are currently using small and mid-sized PABXs
- Toll bypass and Packet Voice become easier to implement
- Does not require users of inexpensive legacy PABXs to forklift upgrade to New World Telephony immediately
- Meets one of the primary needs/requests to date from EMEA and Asia-Pacific
- The Multimedia Conference Manager project is an IOS software image that will integrate H.323 Cisco MCM (Multimedia Conference Manager - H.323 gatekeeper and H.323 proxy) and H.323 VoIP gateway and routing. Multimedia Conference Manager will be supported on the Cisco MC3810, 2600, 3600 and 7200 Series. Multimedia Conference Manager will allow enterprise customers to reduce costs by incorporating these features into a single chassis. An installed chassis can be easily upgraded via a software download to obtain this functionality. This image will also incorporate the mapping of H.323 RSVP requests to ATM VBR SVCs, a very important feature for customers utilizing an ATM backbone.
The features delivered with this XED release will be immediately incorporated into Cisco IOS Software Release 12.1(4)T and subsequent Cisco IOS 12.1T releases.
