S8300 with G350 and Voicemail 1

[heathersue]

Working on a configuration where we want to implement the following:
S8300 server at a central location with G350's at remote locations. call control would be over the WAN, but the calls would not be VoIP - those would stay on the trunks. We'd utilize the survivable processor option in for the G350's.

Given this high level overview, is there any reason why we would also need to centralize voicemail? We've been told by Avaya we had to if we wanted to centralize call processing and have the survivable processer scenario, but we still don't understand why this would be the case. Anyone want to comment on how Voicemail plays in with the whole "hub and spoke" configuration we are imagining with the S8300/G350 scenario?

Thanks all,
Heather

Its because the S8300 is running as a LSP at the spoke sites, so it does not control anything until the G350 is in failover mode. All the call control is coming from the hub site, this being said, this is why the voicemail has to be at the central site. If you need voicemail at the remote sites, you need to do standalone systems..

Hi BuckWeet,

Thanks for responding. I still am having a hard time with this. If I were to put an analog card into the G350 and take 4 ports and hook up to a voicmeail system, then build a hunt group to route to that system, why wont that work? Don't understand how the call control prevents this from working. Once the call comes into the G350 it should ring 3 times or so at a phone, then route the hunt for the voicemail system wheteher it is centralized or not, right?

Well you could do that, but you would have to do in-band signaling and set those ports up as VMI ports..

You're going back to a total analog controlled Voicemail..

Personally I would only want a SMDI VM, or the intuity, which now integrates via the CLAN..

To do the intuity you'd have to do it centralized.

If you did SMDI, or ANALOG you could do it like you want.. For SMDI you need some digital ports though for the SMDI convertors..


Hope this helps

Thanks Buckweet.

Last couple questions if you have some time... What is SMDI?

Are there any con's to doing the VM non-centralized? If we take the G350's and hang VM's off it and route to it w/ hunt groups, can we still have the call control going over the Wan for the calls up to the point where the call goes to VM?

Final question, unrelated... What's the difference between the DS1 boards TN767E and TN464x. Which is newer and what would make me choose one over the other?
Thanks for all of your help!!

SMDI is station message data integration (if i remember right)

basically its a serial interface voicemail unit. all of the call control is sent over the serial link, and the voice path is still done via analog. To do SMDI on definity you really need vectoring enabled. You can do it via other ways, but vectoring is the cleanest.

Cons to doing it non-centralized = more administration work, to send messages to others you would need voicemail networking.

as for the DS1 boards.. The TN767E can do PRI, but it requires a certain packet interface board or something if i remember correctly.. Its and older board that isn't used anymore.. TN464 is the better of the two. It supposed things such as echo cancellation (which I think you need 464F or higher to do echo, maybe 464GP)
Plus the 464 can do E1, and integrated CSU.. Pretty sure the TN767E's can't do that..

You might search around the forum to find a better answer..

Hope this helps

Hi BuckWeet,

Thanks for all of your help with this. I was wondering if you knew where I could find a visio or a stencil for how this all works? I been all over the Avaya website but didn't see anything. Looking to see how it all connects up. Have any ideas? Thanks.
