The following article from Tieline is targeted to broadcasters regarding the coming shut-down of all non-IP-based voice networks.
I haven't had analog copper-based phone service in years.It’s the end of POTS and ISDN as we know it…
When the FCC 19-72A1 order takes effect from August 2nd, 2022, the shutdown of remaining POTS and ISDN services in the US will commence and become real for many broadcasters.
At "Rancho Rosado" I use analog service internally for DECT 6 cordless and two multi-line desk phones.
Until recently my internal POTS service was provided by a Verizon 3G/4G LTE modem with an analog POTS port.
The device, a Novatel T1114, also had an Ethernet port I used for emergency internet access for the LAN when both fiber and cable were down.
Fortunately that scenario has not occurred.
3G is also being sunsetted by Verizon and although the T1114 is 4G LTE, still supported, it does not support IP voice.
Because of this I'm having to decommission the T1114.
It is IP voice that is driving the shutdown of legacy analog copper, 3G and 4G voice networks.
The FCC's "Shaken and Stirred" caller ID verification requires IP voice.
My solution for IP voice came from an Oklahoma-based provider named 1-voip.com
1voip use the Grandstream GT-802 interface which provides two lines.
Each line, at $8.97 US/month plus taxes, costs a fraction of the $26/month I was paying Verizon and far less than the $35/month AT&T wants to activate the voice port on the fiber modem.
The GT-802's voice quality is excellent and network interfacing was simple.
My WAN operates over two carriers and can use two widely different IP addresses.
Since it takes about 10 minutes for the GT-802 to be discovered by the host PBX (1-voip) after an IP address change I had to nail up a route to one specific carrier.
That was about it for setup.
It took about a week to port a 75-year old family phone number from Verizon to 1-voip but it went smoothly.
1-voip.com uses a service called "NOMOROBO" as in No Mo Robo-calls to filter out spam.
Spam calls have dropped to zero.
I've also enabled the FCC's Shaken and Stirred database to authenticate caller ID data.
No MO spoofed caller ID.
In terms of phone calls its been definitely quiet.
