Just pay whatever the ERP vendor asks. The company has made their decisions.
This. They sound pretty clear about what they want to do and pretty clear that they don't want your advice or to include you in decision making. So why go to all the hassle of keeping your existing phone system when they've already told you to ditch it? You're setting yourself up to fail by that route. If you're already planning on leaving in 2018, just sit back and enjoy the ride for the next 12 months or so.
Exactly. I'd look into having the ERP vendor do the phone setup too. No reason to risk getting it wrong, a little money there might make a lot of sense for a one time installation.

@Carnival-Boy let say I'm curious, I'm really going to f*** off this company but at least I would like to understand if there was a solution to not destroy something just "because we can".
From another perspective: if a few seats require to switch to VoIP for a given theoretical service, do I need to convert the entire company to VoIP? is this just an all-or-nothing scenario?
My next job maybe would benefit from this knowledge. If they want they can f*** everything: its their money , but one goal of any job to me is to learn something new. asking to throw everything away can be ok. but I will learn nothing new (also because I will not configrure/deploy/provision anything).
Maybe I'm now just learning that you require an entire migration from analog UTP to VoIP, even for a single seat.

@matteo-nunziati said in the missing VoIP, the ERP and the solution in search of a problem:
we have an optic fiber connection which is then split into the rj45 data line (plug into the firewall), the rj45 fax line wiich is managed by a black box (to me) and provides 3 analog fax lines (on copper couples), the rj45 phone line which is managed by another black box and provides 4 UTP analog lines, those enter the PBX.
how the hell a virtual PBX fits in this!?!?!?!?! where do I put the plug? and which plug?OK, just discovered that the ISP will reconfigure apparata and will plug another eth cable into the router, will plug it into another port of the firewall and will dismiss the eth to ISDN 4-line analog stuff. Killing the current setup.

Is this going to kill my dog?
Are you a shithead, because in my experience only shitheads kill your dog.
what kind? Some could fit!is there a way to let our PBX silently pass external calls to the new VoIP PBX and let this manage the internal lines dedicated to customer care?
Depends. What you got? Newer PRI based PBX? Old ass key system? One of those Avaya IP Office boxes? Definity? Aspect?
Easiest would be an IAX trunk. Next would be a T1 bridge across. Bad would be piping 20/30 analog lines over to a Rhino breakout box.
EDIT
posted the wrong italian link, fixed now.Neglecting current setup (ISDNx4) we have one of this Aastra 400 PBX (pdf), which, theoretically, can be reconfigured itself for VoIP.
New virtual PBX is asterisk based, this is the only info I have currently.
networking-wise, I will need to double the current order for POE+ switches. wiring could turn into nightmare... or not, depending on the phone solution (some phones can act as a small managed switch, you plug your pc in).
Negecting certifications for a little moment, what about VoIP converters like these?
-
VoIP does not require PoE. PoE can be great of course, but you can use injectors wherever they make more sense.
-
Essentially all phones have switched in them so you can essentially always do that. I can't think of an example if someone lacking that feature.
-
@scottalanmiller of course, if a few phones will be moved to VoIP I will consider injectors, but if the entire network has to be redefined, POE+ switches turn to be cheaper and better manageable than ~40 local injectors.

Yes, although it depends heavily on the phones that you choose. We used to buy phones that came with AC adapters in the box. So PoE was more expensive. These days, that is less and less common, but keep it in mind that the PoE might turn out to be purely an additional cost.

@scottalanmiller thanks for the hint!

If you need new switches this can be a good excuse to do it. But as much as I hate to admit it the adapters can be far cheaper
-
@MattSpeller a number of new switches were in order, but if I have to revert ALL phones to LAN, well this more or less doubles our ports requirements, therefore the required switches.

They do make phones with a built in switch, something to ponder perhaps. We have ancient Mitel phones that have a 100mb switch in them and they have been rock solid much to my surprise.
-
@MattSpeller yes, this is another option too but batch in order had not so many POE ports and nowdays most phones has POE. Anyway still waiting for a compatibility list, maybe we can simply go the AC adapter way.

While it's still up in the air go check your network closet and make sure you have enough power to run enough PoE switches. This was the cause of an expensive visit from an electrician for us.
-
You need to stop worrying about additional cost, it's not your money. The company has decided, period. Use this as an opportunity to learn some new stuff. And if you have any influence in purchasing decisions, why won't you recommend switches that you want to play with? You're leaving in about a year, so why would you care if they buy POE switches or use power bricks.
-
And if they don't want to buy what is needed... they can sit around without working phones

Not a bad idea.

Most are GigE these days. But there are 100Mb/s ones lingering.

@MattSpeller we have production plants, electric power is the last problem. even the smallest closet is reached by ludicrous power with oversized cabling (just in case). I'm theoretically able to put a milling machine in any corner of the company (infact we have 6 of them).
but thanks for the hint! -

impossible: the PBX is fully operated by the supplier. period. the only interesting thing was to understand how to not nuke a plant while introducing VoIP tech in it.
