Shiling, I used to manage a CS1000, and still follow the product from time to time. I now manager a Cisco UCM cluster. I like the Cisco Cluster.
This is a post from a Nortel mailing list I'm on, the person posting was David Zeter from Montana State: Mailing list for Northern Telecom related issues <nortel-l...@tgrace.com> http://www.tgrace.com/mailman/listinfo/nortel-list <quote> the last day of the joint InAAU/INNUA/Insight 100 User Conference in Denver, and here is what Avaya has said: First off, the 7-year window of support that Rick references is the minimum time from when a product is announced end-of-sale (minimum of one year of sales from the announcement, plus 3 years of software support for patches, feature updates, additional licenses, etc., plus 3 years of hardware support). That is when a product is at end-of-life. At this time, only two products have been flagged for end-of-sale - the MCS-5100 and one other (the something-500, I can't remember the three-letter prefix). There is no plan to end-of-sale the CS1000. There is a new dual-core processor card, and a new processor/media gateway combo-card coming out for the small systems; a conversion path for turning a CS1000M (migrated Meridian switch) into a CS1000E for geographical redundancy (with up to triple cores); software release 7.0 coming in summer, with another release in the pipe. As of release 7, there will no longer be a TDM-only (Meridian 1) version sold - all systems will be sold as the CS1000, IP-enabled switch, with a signaling server. The Avaya Aura system is the developmental future of both the heritage Nortel and heritage Avaya product lines, but Aura can be over-laid as a SIP application server on either product line. Our CS1K systems are not going end-of-life. CallPilot and Avaya's Modular Messaging are going to be merged into a new, Red-Hat Linux based messaging system currently called Messaging 6.0 or Next-Gen Messaging (they'll give it a real name soon - it's currently in beta, with the first release going GA in the August time frame). CallPilot is held at release 5.0, with the release 5.5 and 6.0 feature improvements coming as Service Updates. End of sale is unofficially planned in about two years, but there will be license migration to the new system, and the release 5 hardware will support the new OS and messaging applications, so there is forklifting in themigration. The second-phase release of the new system in November will include a CallPilot TUI, so the user experience will not change much. There is a lot more information coming out in the June product announcements. For those who would rather have real information, instead of speculation, I'll suggest joining INNUA, and participating in a local chapter and conferences. The membership will transfer to the new user organization (IAUG - the International Avaya User's Group) when its structure is finalized in the fall. Avaya has expressed a commitment to open communication and support of the new IAUG. I've never been a big fan of Avaya, but I'm pleased with most of what I've seen so far. <end Quote> On Tue, Apr 5, 2011 at 1:02 PM, Ding, Shiling <sd...@fsu.edu> wrote: > Well, I am actually interested in VoIP topic too.
