We still run into the stigma that "VoIP is bad" sometimes and although most people will eventually get over it, some do not. A lot of our clients are very rural and just do not want IP... They want 5 phones with 2 lines and a shared fax, put a caller on hold here, press All Call and make a page, go to any phone and press Line button to answer calls. Most of these locations would have old Partner, Iwatsu, Toshiba, Comdial, or similar digital phones and they don't want anything else.
The cabling thing is funny... We see offices with say 3-6 employees, just a wireless router with a printer plugged into it and everything else is wireless... They don't want to pay to get Ethernet cabling just for their phones.
This is not for one customer, but it isn't a majority of them either, it would be a select few... Maybe a 6-10 systems a year.
Used isn't a viable option, customers want new. I know Avaya still makes and supports digital phones on their IP Office platform. I don't know, maybe Avaya is the only alternative right now... That is why I am asking if there is a small(ish) company out there making specialty products I am unaware of.
With the sunsetting of the MiVO 250, we don't even look at Mitel for anything under 100 phones unless it's hospitality... Our primary push is our own hosted platform... For better or worse, it is what it is and the direction of the company, but we still want that small digital option because we see the demand (although small) from our customer base.
