Resiliency Settings for Server Edition 9

[pralph]

I am running linux virtual server edition (latest and greatest 9.0), I have 5 V2 chassis that are going in remote locations for TDM access (PRI). All my users and licensing is on the core server and I am using purely IP sets. My issue is, the customer is wanting three levels of resiliency. In other words, the users register to the core if it fails they register to the backup (virtual server) server, but if the network link goes down they want it to register to the V2 chassis. I can only find two levels of resiliency and the 1200 series phones only show one setting for the server after we updated the firmware to work on 9.0. Anyone doing this or even know if it is possible?

Thanks

Not possible at this moment.


BAZINGA!

I'm not insane, my mother had me tested!

It's a SME system, you're talking Enterprise levels of resiliency there. Also forget it ever working with 1200 series handsets regardless

 

[tlpeter]

It is only for the 96xx (and maybe the 16xx) phones.

The 1200 series handsets actually work when registering to the primary server and then the backup server, but that is as far as they go. I have tried with 96XX phones and couldn't get it to work. Everything you guys are saying is what I believe to be the case, but I am getting conflicting information from Avaya....go figure.

When the primary SE is the dhcp server then the phones will get both IP addresses as callserver and should fallback after three minutes of no connection to the primary.

It doesn't ever failover to the 500 though and effectively become a "standard IPO" though does it?

 

[pralph]

That is the question @amriddle01. From my testing, I have been able to make the phone register to the prime and then the backup, but when I remove the link to try and force the phone to look at just the V2 chassis, it just sits there trying to find the prime or secondary server. I am basically wanting to make sure that this is how it is supposed to work and that I am not missing any needed configuration or whatever to make this work.

 

[tlpeter]

It does not register to the IP500 but to the primary and the secondary.

you could register the phones locally to the 500. you still only have one level of backup you can choose either the Primary or secondary. its how we have been installing most of ours to get the sites to have stand alone capacity. also you dont need the server or 500 to be the dhcp server and it will still work.

@kwing11200

you are registering your IP sets to the 500 V2 chassis and all the licensing is centralized and when the chassis loses connectivity, the IP sets are staying up and are able to make receive calls on the 500? Sorry just wanting to clarify.

 

[kwing112000]

Correct.

Should clarify if the 500 loses connection then it will have NO VM at all.

Here is what we have tested and made work.

The avaya/nortel 1230 SIP phones can register to either the "core" server or the expansion V2 chassis. Whenever the phone loses the link to whatever device it is registered with, it is dead in the water. This is a limitation of the SIP phone, not the Server Edition solution.

The avaya 96XX phones (I am using the 9641) however will register to the core or the expansion as well. In my scenario, I have them registered and built on the V2 chassis. If the network link between the V2 chassis and the Core server goes down, the phone will stay registered to the V2 chassis and the whole chassis will then re-register to the "Secondary" Server Edition Server (if applicable). If during this time the secondary server goes down, the phone will continue to stay registered to the V2 chassis and will be able to make and receive calls as if the V2 chassis was a stand-alone system.

If the V2 chassis goes down, the phone will re-register to the Core server and will be able to receive calls from the other users/HGs in the SCN.

pralph,

The Server Edition is working ok? Because my Server Edition not work 100%.

 

[pralph]

So far, yes it is working. The only thing that I have found is a no audio issue on one of the PRIs, but when I turned "allow direct media path" off, that fixed that issue.
