Sunk Cost Fallacy?

My current phone system looks like this.
Building 1
old digital system 60 phones
Building 2
VOIP, 39 ten year old phones
Building 3
VOIP, 18 two year old phones@Dashrender tell me if I got this right.
Building 1: Legacy Mitel system, supports SIP trunk and 60 digital phones.
Building 2: VoIP capable Mitel system with 39 SIP phones and SIP Trunk support
Building 3: VoIP capable Mitel system with 18 SIP phones and SIP Trunk support.
Not specified 1: How are the 3 systems trunking calls to each other.
Not specified 2: Are there legacy POTS line in use also. -
The issue with phones is that the current VoIP handsets are not SIP compliant and can't be used with a modern system?
-
So 117 total handsets? How many of those need to be physical?
-
Just doing really quick numbers, if you went with standard Sangoma SIP phones (the ones made by the FreePBX people) at default Amazon pricing (no bulk discounts or special rates) that would be under $8,800 to replace all 117 phones. Any old phone that still works will save money, any softphone that can be used will save money.
What's generating the $11,000 of unknown costs for option 4?

I assume that would be infrastructure updates... Running new wires to the location that the digital​, non-sip phones are.
But that's just year one costs. The year two costs will be effectively zero. I wonder what the maintenance for the mitel system ends up being.

That's not a great phone

Bare bones for sure, but it works. Have you seen issues with it?
-
None of the same girl my phones have gigabit passed through until the $150 model. I simply do not see any good benefit to those low in phones you gain auto provisioning for free and I think one other thing from commercial model for free because

Specific to the case at hand I was recommending the T46S for the number of buttons to be comparable to their current phones for features
Those are 145 @ telephonydepot in bulk
-
Soft phones are almost never an actual option for general office workers none of them have spots for all the buttons to replicate a desk phone so you have to train users to put calls on park you have to train users to transfer with codes that shit just does not work in the real world

I hope that that is Siri talking.

Yeah S a in GOM a

I agree with Jared that using soft phones as the only replacement just isn't practical.
Ignoring the lack of features on most soft phones, user training would be a huge burden.
For the few users who are constantly traveling, sure give them a soft phone in addition to their office phone.
But the simple approach is a physical phone.
-
That's why I only mentioned softphones for some cases.

Building 1: Legacy Inter-tel, no clue if supports SIP trunk, 60 digital phones (I assume is support some form of IP based phone communication as it uses IP to transfer calls between the three different currently installed systems - presumably SIP)Building 2: yes
Building 3: yes
Not specified 1: The Inter-tel/Mitels have their own integration solution to talk to each other. They are fully aware of all extensions, etc on the other switches.
Not specified 2: Yes, there are POTS lines in all three buildings, and some of those lines run through the PBX in their building.

The Mitel handsets are SIP compliant, though my research has shown them to be challenging at best to get to work with - as Scott puts it - modern systems.
-
@scottalanmiller said in Sunk Cost Fallacy?:
So 117 total handsets? How many of those need to be physical?
Nearly all, if not all. Perhaps 30 of them in total are actually assigned to a person. These could be softphones on their PCs, but this would be a very hard sell to management.

Just put a dollar value on it and let them decide. Not really an IT thing.

You found GB passthrough phones for $75/ea? That smashes JB's bulk discount rate of $150/phone.
Additional costs include a minimum of 10 lines that need to be run (CAT 3 currently) and POE switches, I don't want to deal with power bricks. -

Also, it's never passthrough, it's a two port switch. Important at a networking level, switched Ethernet can't passthrough.
