VX FAQ
The Telos VX uses VoIP. What does that mean to me?
Let’s define what “uses VoIP” means. The VX uses it in two distinct ways: One: it can connect
to Telco services using standard SIP VoIP. You benefit from having options –connecting to PBXs
digitally, to ISDN and analog lines via gateways, etc., etc.With VX you can finally integrate your
on-air phones with office phone systems from a variety of vendors. Getting Telco service from
VoIP dial tone providers means that your audio quality and hybrid null will be much better as
VoIP dial tone is delivered “4 wire” without hum, noise, and loop loss. Building on ubiquitous
VoIP standards means a variety of third party hardware can offer flexibility. And you might
save a lot of money getting service this way. Two: VX system components connect to each
other over standard IP/Ethernet networks with all the advantages that brings. For example, in
Livewire-equipped facilities, one RJ-45 jack connects dozens of audio channels and rich control
to phones-like controllers, PC applications, integrated console controllers, etc.
So I can use the VX with my regular 1MB POTS lines? How? Can I use ground start lines for
incoming calls only?
You can do that, and it’s not difficult. You only need a POTS gateway device. However, we
encourage using digital delivery for the best sound quality.
What about ISDN BRI and PRI lines?
If you have ISDN now and want to keep it, again there are gateways available. However, it is
often cheaper to port these numbers to a VoIP dial tone provider. All of these options are worth
considering.
So I can experiment with SIP VoIP trunks? Why would I want to do that?
Actually, we recommend it! We think that you’ll find that they work better than you may have
expected, as many of the VoIP problems we have seen are caused by limitations of analog
terminal adaptors (IP to POTs gateway devices)! Since these are not needed with a VoIP-based
system such as the VX, that class of problem is eliminated. There are a number of inexpensive
ways to try VoIP without risk. You can also get VoIP-delivered numbers from distant area codes
and exchanges. If you’re paying mileage for foreign exchange lines or have national toll free
numbers, you’ll definitely want to consider this option.
I can’t put a flasher across a VoIP line, so how can I flash a light when the hotline rings?
This same issue arises with ISDN, so beginning with our TWOx12 we included a GPIO output
for this function. The Not to worry – The VX has this capability. In fact, it has multiple oututs
which can be assigned to any of your VoIP lines.
I have been watching VoIP with interest. But reports I have heard about services such as Von-
age are that sometimes they work well, but other times not. Frankly, I surprised to see Telos
advocating it.
We get this concern often and understand why you ask. The term Voice over Internet Protocol
