If anyone is interested, it turns out the new firmware that they were
having to use on the Mediatrix 410x worked fine. Whatever options it
presented upset the Verizon SBC engineers. That kind of sounded like BS
to me at first. They went into a little more detail. They said that the
extra data may seem minor, but it was enough that that they couldn't
certify the devices (with that firmware) as compatible with their VoIP
network. It wouldn't be a big deal if just our sites used it, but they
refuse to certify it for Verizon configuration and mass deployment
(Verizon techs are doing the install) therefore it cannot be used as
part of our setup. This would obviously affect their future deployments
as well. They asked Media5 to make a firmware that meets their
standards. They plan to build it, but apparently there will be months of
development and testing. I gave Verizon my Patton sales pitch, but
similar issue. Not in their certified product list, so not in the cards
for any type of deployment in the near future. They have an Adtran
device that they say will do the job and is in their list. If they can't
figure it out, I'll give up on Verizon doing this I guess and we will
figure it out ourselves.
Thanks for the tips and suggestions.

I must have misunderstood the engineer.
Salesperson gave me the options below and said I would have to go with
the 2 separate devices. The tech had a bit of an accent but I swear he
said I could configure a port on the 8 port device as an outbound
emergency POTS line.
OPTION 1:
SN4526/4JS2JO/EUI
-4 FXS and 2 FXO
OPTION 2:
SN4528/JS/EUI
-8 FXS
SN4522/JO/EUI
-2 FXO

Thanks (thanks for the those with the off list replies too).
I spoke with a Patton engineer, and it looks like the 4520 series
can do what I need.

I sent a note to Verizon indicating they are going to need to
think outside their 'product catalog' if they want to keep the
project alive.

Patton has a combo device also (2fxs/2fxo). In either case to
interface with
the old pbx or key systems you want fxs devices to connect to
the old CO
ports on those old systems and give those pbs "dial tone"
which can then do
a sip register to verizon if needed.
The patton dial plan is flexible enough (example) with a fxo
device, if
someone dials "911" we can have it drop an active call, and
complete this
emergency call.

Subject: [sipx-users] Relatively off topic - FXS with POTS
failover
This has nothing to do with Sipx at all. I couldn't think
of a better
group to ask though....
If that makes this completely inappropriate, I will not add
any more
emails to this thread.
We have 50+ locations where we cannot currently practically
put in new
Sipx systems because of cabling issues. They all have old
school systems
with 8 to 15 handsets and 4 to 8 POTS lines. As part of our
overall VoIP
contract with Verizon, they are putting in FXS boxes at each
of theses
sites so we can use Verizon SIP services without replacing the
infrastructure.
Verizon uses Mediatrix 4100s for this. It is a 4104, 4108, or
4116
depending on the numbers of POTS lines currently in use at
the clinic.
We are leaving one emergency POTS line for backup outbound
dialing only.
This is critical that outbound dialing is not affected if the sip
trunk/wan circuit goes down.
At our pilot site, Verizon put in a 4108, and everything
seemed to work
fine until we tested the emergency scenario. The 4108 simply
bypasses/patches one of the ports directly to the emergency
POTS line.
This doesn't work for us. We never know what line these phone
systems
are set to use, and our testing has shown that different
handsets in the
facilities pickup different outbound lines. We inherited all
of these
clinics, so there is every type of PBX known to man.
Attempting to
reprogram them is not an option. Verizon's plan was to add a
second
device called a Mediatrix 1204. It appears to basically be an
FXO box.
They also were going to use a new firmware for the 4100 box
that allowed
it to fail over to sending its sip traffic to the 1204 if the
primary
Verizon sip trunk was inaccessible. The 1204 then sent it out
a POTS
line. I didn't really like the complexity of the design, but
I was
wiling to go along with it because Verizon was pretty much
going to eat
the cost since their setup didn't perform as they advertised.
Surprise, surprise, at the last minute, we find out it
doesn't work. The
new code on the 4100 is failing their tests and not working
as advertised.
After this discussion, I told them they need to look outside
their
'product catalog' and see if there is a more appropriate product.
What I need is an FXS box that can intelligently route calls
out a
backup POTS line if the SIP trunk goes down. Does anyone know
of a
product from Audiocodes, Patton, etc, that can accomplish this?
I will be glad to discuss off list if anyone wants to give me
a hand here.
Thanks,
Matthew
