Long story,

TLDR Version: NEC Aspire version 6.11 can i do qsig over SIP?

New plant as a Avaya Definity.

Current Corp office has NEC ASPIRE.

Was told months ago that both systems can talk via QSIG.

When i asked my dealer he said yes the ASPIRE supports qsig.

We currently have a VOIP card with 4 h.323 trunks going to our 2nd location that has the NEC ASPIRE as well.

Now our upgrade and reprogramming of the definity is 3 weeks away.

I call up the dealer again and ask about configuring QSIG. He initially sounds clueless about the matter. And comes back saying it will only handle qsig over isdn.
:bang:
When i asked about qsig he said their is no configu menu its either on or off.
:bang:
When i asked about seeing if its on or off he said its off.
:bang:
When i asked about turning it on he said buy an isdn card and i will turn it on.

I feel like he is jerking me around and has no clue about the actually system he is just trying to sell me crap i dont need.

So i want to know do i need an isdn connection to do qsig on the nec aspire. And my avaya tech i have been working with says usually on the hybreds he has dealt with that qsig is default on. The two other dealers i called in the area one is a wrong number the other does not like the NEC systems and dropped carrying them 5 years ago, and he doesnt even want my business.

Hopefully someone hear can answer my questions.

And possible can work out something for helping configure it on the day i plan to go live with the phone switch at plant 3.

Also when working with the avaya engineers on the upgrade they where able to get the definity to talk to a NEC ASPIRE via qsig I am awaiting information as to what the config setup of the NEC ASPIRE was when they got it to work.

Tried to edit my post, Wanted to be clear on the when he said qsig would only work over isdn his reasoning was a page out of the Aspire manual that was word for word the copy paste from the QSIG wikipedia page.

https://en.wikipedia.org/wiki/QSIG

Qsig is done over a point to point T1. (we use PRI over that T1. NEC systems work great, are pretty easy to program and have tons of features...if you know what you are doing, like anything else in life. Yes, you need a T1/PRI card on the Aspire. The Aspire can only be an end point on a QSIG network not a tandem switch. I am surprised you didn't just get a new UX5000 for the plant..the networking on the NEC systems is damn good. QSIG will only give you the most basic feature set though. I have actually put an aspire on a Tadiran QSIG network (Tadiran pretty much wrote the book on QSIG FYI) and it works.

We are getting a MPLS point to point between all 3 sites at the same time we are installing the servers and upgrading their phone switch.

My intention in 2 years when our lease is over on the NEC (Dealer somehow got the lease to say FMV instead of $1 buyout on the lease) is to go with the definity system.

But thats irrelevent for the current situation. Back to the topic.

This means that i have to go with the ISDN? or will a VOIP \ SIP trunk work? Just needing the ISDN card to "turn qsig on"?


Just needing to know if i have to purchase the ISDN cards for the routers and NEC switch.

Avaya can use QSIG over sip \ voip \ isdn or anything else.

Also when you mean its only an end point does that mean i can only receive the calls from the aspire and not make the calls?

Some new information is that our routers will only handle a BRI not a PRI, i see where the aspire and avaya will support BRI, but being the BRI is so limited i would prefer to find out if i can do this over a SIP \ VOIP trunk.

End point meaning...you can't use the Aspire for a pass through switch in a QSIG environment. Is your intent to do QSIG over IP? Sounds to me like the dealer was correct in stating that the Aspire does indeed support QSIG...the devil is in those details though. I see QSIG ONLY supported on the ISDN programming on the T1 blade in the software manual. I mean, depending on your application you could simply try and get some VOIP sip channels established for site to site calls.

Application is everything and it seems like an issue with design and implementation. Who came up and designed this scenario and what were the expectations?

Talking with an NEC Engineer at the NEC office Sip trunks using F-route sounds like the way to go.

The NEC engineer said the QSIG in the Aspire system is proprietary and not true qsig.

And yes all i need is to dial the persons extension and get routed down to that extension, i dont have any worry about caller id and what not.

Of course our routers being HP ProCurve (Bean counters know way to much IT and didnt want to spring for Cisco) will only support BRI not PRI.

Also the NEC Engineer is willing to talk to my avaya programmer to find out what i need on the NEC side.

Side note, avaya gave me everything i needed on the definity side without pulling teeth.


The design started with the avaya tech asking if NEC supports the qsig to talk between pbx. I confirmed with the dealer saying a simple "yes".

Then we checked with avaya engineering to verify the system was supported. Which avaya says yes their engineering was able to do it, with the configuration we proposed (No isdn card on the definity) connecting to an NEC Aspire.

Once they confirmed i requested information from NEC and the tech to be on site with to setup the NEC side, all i got was an OK he will be there.

This was 2 weeks ago asking the tech to be here to program the NEC to do the NEC side of the connection to the definity.

This week my avaya tech asks me for the VOIP configuration settings from the NEC system so he can match it to his settings for programming.

This is where the NEC dealer gives me the "Huh", like he had no idea what i just asked. Then he comes back saying i need the isdn card, even though avaya engineering stated they didnt need ISDN.

This led me to asking on here today as i spent most of the day yesterday trying to research this myself.

Also called NEC corporate yesterday afternoon which the gal sent my question to a engineer. Figured between, posting here, the Engineer, and my avaya contracter asking the avaya engineers for their spec's on the NEC, one of them should work.

And thankfully the post here supports the response from the NEC Engineer, in that my best bet is to us SIP trunks to do the site to site calls.

So thank you for putting up with my ramblings and giving me an some answers. I am starting to understand some of the terminology so i am probably a bit confusing on some points.

I just wish NEC would have their manuals as easily available as avaya, maybe then i would be happier in dealing with NEC. Probably my dealer is the bigger disappointment in him just more willing to make me spend money than giving any real support.

You can use SIP trunking between a Definity and an Aspire.

Actually you can SIP trunk into and out of the Aspire and the UX5000/SV8100 with just about any sytem that supports SIP.

As per above the Qsig will only work via ISDN. But with SIP trunks the Qsig is not needed.
But first you must have a VoIP card to do SIP.
If you have that, then your good to go.


The NEC side needs the SIP trunk programming done, The IP addresses set and the extension numbers set up for DID Incoming.

The outgoing can be set up via F-Route.

The Trunks need to be set as Tie Trunks,and as above no Tandem trunking through the Aspire. Just station to station calls.

You need a good NEC Aspire tech to do this.

Thats exactly what i need.

I will post with the results when its done.

Thanks.

Cool.

Reading what transpired seems that there was A TON of assumptions made with little or no knowledge. This is a good thread to show others doing the same upgrade with other systems.
