Subject: AT&T, Verizon, T-Mobile quietly walk away from ZenKey joint
venture
By Mike Dano
ZenKey looks dead.
The company's app is not available in the major smartphone app stores.
Its website does not load. And the wireless providers that launched the
joint venture in 2020 are no longer supporting it.
AT&T stopped supporting the service last year, according to its website:
"On April 7, 2022, ZenKey will no longer offer sign in services on our
websites. Once it's removed, you'll have to use your AT&T user ID and
password to sign in to your AT&T account or services."

Subject: Verizon customers were unable to call 911 in Minneapolis,
Brooklyn Center Monday morning
The issue was resolved late Monday morning, according to a spokesperson
with Verizon.
By Dana Thiede
MINNEAPOLIS — Officials say the issue involving Verizon wireless
customers throughout the Twin Cities not being able to use 911 for
emergencies has been resolved.
According to a spokesperson with Verizon, the issue was resolved just
before noon after customers were unable to call 911 for several hours
Monday morning. It's unclear all the areas that were impacted, but both
Minneapolis Police and Brooklyn Center Police posted on social media
alternate numbers to call for emergencies.

In Switzerland, they had to be replaced either by GSM (and 4G/5G
presumably, because 2G is already obsolete, and 3G will become obsolete
soon), or VoIP.
I heard of some cases where they still had the analog dialing devices
(the WSG35-2 was very popular, it was a modem that could also just dial
and then switch to an analog microphone). They now plugged those to the
ATA port of a VoIP router. As long as the dialing device uses DTMF to
dial, it works like a charm.
Then you just need to either ask those systems to poll the central
monitoring system every now and then to check they are still
operationnal (which most of those systems did anyway in the past
already). They usually used DTMF for checking-in, which works best when
decoded at the ATA itself.
If they used real modem modulation, they are better off replacing the
modem part completely by an IP signaling or GSM system, although my
tests have shown that the VoIP network can still mostly work at 2400
bits/s with e.g. V22bis seems to still work. I could not get higher
speeds even with parameter tweaking and no codec conversion. I used real
modems on both sides: using a DSP directly attached to the VoIP network
might get much better results.
