LSP Advantages

[ONsiteengineer]

Hi,

What are the pros and cons if I will install my sytem as LSP or stand alone at our remote site? Because if its stand alone, when the link is down, it can still process remote calls right? Pls . explain more about this. Thanks a lot.

LSP = Local Spare Processor.

When the link is down between the LSP and the main site, the local site can still process local calls, because it then becomes a stand-alone site. However, everything is administered from the main site; you don't have to sign on specifically to the remote/LSP site in order to make changes.

We have quite a few LSP sites, tied back to dual 8720's. The advantage is that we have one big switch. Everything acts like one autonomous telephone system. The maintenance and knowledge base is a little different on the LSP configuration, so there has been some learning curve here. All-in-All, a pretty good setup. Survivability is retained through the LSP processors, and we can still share resources (trunks/voicemail) across the WAN.

Opps, it's Local Survivable Processor.

I also like the fact that the LSP will auto-recover and come back online to the mothership.

One big advantage with the LSP design is single licencing. You use one pool of licenses for the whole system. With individual systems you have to add station licenses to each remote system as they are needed. Then if you cut back on phones at a site you cannot use those licenses at another site that might need it.

You can also use one voicemail system instead of having separate systems and licensing for the voicemail. The down side is that in LSP mode there is no voicemail.

Thanks a lot,

If I have my LSP installed, I will use the same dial plan with my primary for remote site? Also, Is there a way which I could have separate ARS and different routing for my remote phones? Thanks alot.

Yes, the same dialplan, because, it's the same switch.

Yes, you can add "multiple location ars", which is a separate table and routes for each location.

Ok. So only the dial plan would be the same right? Can I also make a separate auto-attendant for my remote site?

 

[ONsiteengineer]

In my disp sys cus, I have my multiple location= 'n'.. Does it mean I could not have it?

 

[Mitch672]

That RTU will need to be turned on, yes.

Yes, you can have separate auto attendants, that would be done in the Audix or IA770 (or Modular Messaging), whatever you are using for a voice mail system.

Instead of seperate Auto Attendants you should build a vector and keep the annpuncements local to the LSP so in the event you lose connectivity to the main site you stil have at least your AA working as a vector

Thanks for all your replies..

Mitch,

How audix will work as my auto attendant? How to configur it?
