I have a question that I pray someone can answer. Well a couple really..
At my work we have an ESI IVX S Class phone system.
The first question : Is there anywhere I can get the hard core manuals for these phone systems ?
The second question is : The caller ID almost NEVER comes up right. Sometimes it says "UNAVALIBLE 314" and sometimes you can see the name and part of the number. I think its a setting in the CID it's self but can't be sure until I read about these phones.
Thanx in advance..

As with most systems, the Installer Manual is kept close to the vest for actual installers, specifically authorized dealers. There is a reason for this. A typical user could get themselves into a lot of trouble with access to technician level programming. A system could be taken out of service, as far as a user is concerned, with a few incorrect programming steps.

As far as the Caller ID, I would see if you can find an authorized dealer, maybe the one that installed the system, to check into the possibility that the Caller ID gain needs to be adjusted on the system. They may need to contact tech support to make the adjustment if it's not available in technician level programming. Some earlier systems, and especially the S-Class, didn't allow the technician to make adjustments to certain engineering settings.

While I understand this point, the real fact of the matter is greed, not much to do with anything else. With Norvergance screwing us the way they did, we can't really afford to pay someone to come out and fix something that never worked right to begin with.

This is certainly possible, and how nice it would be to know how to do this.

*******They may need to contact tech support to make the adjustment*******

We tried that, and I could feel ESI's tech support staring @ me blankly on the phone, there was silence and then he said it.. "I have never heard of that before, let me call you back after I speak with our techs." And of course the call never came back..

******** Some earlier systems, and especially the S-Class, didn't allow the technician to make adjustments to certain engineering settings. ************

That doesn't surprise me either.. Once again we fall back to the basic behavior of man, Greed.

I have half way hacked my way through the phone on one level, although I still haven't gotten anywhere near where I want to be. A co-worker and myself opened up the ESI IVX S Class box where everything runs and pulled a few things out, dumped their contents and are currently looking @ the results. I will hack my all the way through this phone system if I have to and release anything and everything that I find.
Some people may say "You will break it, and then where will you be ?" Well considering Norvergence creditors are "Suing" us for the phones back, I could care less if they do get broke. If they do manage to stop operating, I will pack those bad boys up and ship them back to where ever they want. Then I will propose we purchase a different more OPEN phone system. The surprising thing is, there are more things out there than people realize and most of them cost 1/10 of an ESI phone system. The only trade off being, one has to have be a techie to be able to set them up. The quaility is the same or better than ESI as I can say they have been less than perfect. In all this not one company has stepped up and even offered a discount just to get their foot in the door. Once this POS is gone, it's gone for good. I will setup my own phone system using ESI hand sets and open source software and open source VOIP software.
So much for hoping to get this crap all patched up.

"I will setup my own phone system using ESI hand sets and open source software and open source VOIP software"

good luck!!

Good luck crash. Seen a bunch of MIS guys that have their MCSE's think they can do it and lose their jobs shortly after both the network and the phone system are screwed. The ESI is a decent system for a business your size I would think. I have worked on open source PBX systems like Asterisk and all I can say is that I hope you have a lot of time on your hands and people that don't mind have no phone service for periods of time. BTW the voice quality is not better on IP phones...by quite a bit even using G7.11.

Why don't you call ESI and see if you can get certified on the equipment if you want to do the programming? I personally could care less if people program their own phone systems..it generates tons of work for me after I have to come clean it up.

Why did I know my response would get this kind of response? Not sure why I bothered, now that it's been picked apart.

Your problem sounds to be with Norvergence and their creditors, not ESI.


It sounds more likely that you spoke with a salesperson who dropped the ball. Any tech would have been able to suggest some remedies.

After you have invested huge ammounts of money into the hardware to allow VOIP to function well, and upgraded your internet pipeline to handle the bandwidth necessaryu for your voice and data, and purchased the VOIP phones that you will need, I would guess that you will end up paying 3-4 times as much for an open source system that you would have paid to have your system set up properly by a competent professional.
Also, what you will be paying for your bandwidth will continue month after month.
I wish you well in your little project. You will need it.

Joshua,

If this is how you come of to any vendors I think you'll be getting quite the opposite of a discount.

Good luck on your quest for an open system, as Coral said the learning curve is steep and I'm assuming you'd be the "techie" responsible for selling and maintaining this free open architecture all on company time, they are going to love you.
