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 phonesThe old digital system (just the phone switch part) has be EOL'ed.
So we are considering our options.
Option 1) remove old digital system completely, replace all phones with VOIP phones, which will require 2 new switches and 10 new cable runs. Rough cost $26K
Option 2) replace old digital system with new VOIP backbone system with digital subsystem to support old phones (phones are still on the manufacture production list with no EOL listed). Rough cost $7000
Option 3) replace old digital system with FreePBX and new IP phones. *this is only plausible if we can do local style calling between the new FreePBX and the existing VOIP phone systems. Rough cost $11,500
Option 4) replace all current phone systems with single FreePBX and new IP phones. Rough cost $20,500
So, thoughts?

What is generating the different costs?
-
At first glance, option 2 with migration phone by phone over time would make sense.

Option 2 is a Mitel VoIP enabled system. So he is keeping his vendor lock in.

What is generating the costs for the FreePBX system?

Looks like handsets. And maybe some wiring.

Hmm. Wonder how much of that would have to be done eventually anyway? I imagine that long term cost savings with a Foss PBX would outweigh the initial investment.

Easier to use, easier to support, no lift and shift down the road.....

I think these numbers are a bit biased and don't take into account potential savings. Maybe a 5 year cost comparison would be warranted.

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.
