hi I'm Larry from North Florida
communications and today we're going to
discuss SIP trunking the purpose of this
video is not to go into a whole lot of
technical details but to give a basic
understanding of how that trunking works
so business owners and business managers
can decide whether it's right for their
business or not
for the sake of our discussion SIP
trunking is a telephone service
delivered via the Internet SIP trunks
can be delivered by other means but the
Internet is the most common delivery
method SIP trunks are provided by an I
TSP instead of the traditional phone
company itsp stands for Internet
telephony service provider there are
several reasons why businesses consider
switching to SIP trunks but one of the
main reasons is cost you can save 50
percent easily of the cost of
traditional phone service in case you're
wondering SIP stands for session
initiation protocol in order to use some
trunking you'll need a good solid
internet connection a telephone system
capable of using SIP trunks and service
from an I TSP and something a lot of
people don't consider a router that can
prioritize SIP trunking the type of
internet connection you'll need depends
on the amount of traffic you'll want to
pass and the service providers in your
area a t1 is the digital circuit that
has a speed of one point five megabits
per second that speed is relatively slow
by today's standards but a t1 has some
advantages the main advantage is that t1
is a dedicated connection unlike cable
and DSL the t1 service provider
guarantees that you always have the one
point five may expedia one is also
synchronous meaning that the upload
speed is the same as the download speed
another option is dsl generally provided
by the local telephone company dsl
speeds vary depending on how far you're
located from the phone company's
equipment and how much you want to pay
the asal download speeds can be 3 5 10
or even 20 megabits per second unlike a
t1 DSL is asynchronous which means the
upload speed is not the same as the
download speed you may have a 10 Meg
download speed but your upload speed
will be typically less than 1 Meg when
considering DSL for SIP trunking the
upload speed is just as important as the
down
load speed a third option is cable
internet cable speeds are typically
faster than DSL with download speeds
that can reach 100 Meg upload speeds are
typically hired in the SL some might
even go up to 10 Meg for the high end
service we typically recommend cable
internet if a connection is available in
your area
cable usually provides the best service
for the prize there are other internet
options available in some areas but a t1
DSL or cable are the most common you'll
need to have a phone system that is
capable of receiving SIP trunking you
may also use a sit to analog gateway for
older telephone systems a sip gateways a
device that will break SIP trunking into
individual lines that replicate pots
lines pots is an acronym for plain old
telephone service just like you get from
the traditional phone company a gateway
will allow you to keep an existing phone
system that will not natively accept
subtracts saving money on an upgrade
however you will lose a lot of
flexibility of SIP trunking by using a
gateway to get the best juice from SIP
trunks you want to get a phone system
capable of directly integrating with
them most manufacturers have these type
of systems but our company refers to LGI
PEX voice over IP phone system will any
router work no and you shouldn't scrimp
in this area router is your gateway to
the Internet your router directs traffic
to and from your network to the Internet
in my opinion when people move to SIP
trunks one the biggest mistakes they
make is using a cheap router cheap
routers are simply a big no-no they're
mass-produced to the lowest cost with
very little processing power and very
little if any prioritization of traffic
I was suggested if you can buy the
router in a big box store it's not good
enough for your business much less for
SIP trunking you want to invest in our
higher in Robert has plenty of
processing power and can provide quality
of service quality services simply
referred to as QoS QoS is find as the
ability to provide
different party to different
applications users or data flows or to
guarantee a certain level of performance
to a data flow when using SIP trunking
is critical to the voice traffic going
to the Internet is prioritized over all
other traffic if your email arrives the
second late it's not a big deal on the
other hand if a voice packet arrives one
second late your conversation has just
become garbled I properly configured
I'll ever use QoS to provide all voice
traffic priority over everything else
so to cure conversations remain smooth
and clear just as important as buying a
quality router is the need for someone
who knows how to set it up you'd be
surprised at how many IT techs have a
difficult time with this what kind of
rather is best
that's the question will be answered
differently by many people cisco
SonicWALL WatchGuard and others make
some top-notch routers in north florida
communications one of our favorite
routers is an open-source project called
PF sense we found that PSNS works very
well with voice over IP traffic since
it's an open-source product you do not
have to purchase the software and can
use the money saved to invest in some
good hardware for more information on
PSN visit PSN style work so we talked
about the type of internet connection
that you can use what type of phone
system to use and that you need to use a
high quality router so what else do you
need to in order to use SIP trunking an
Internet telephony service provider
again refer to it it's an IT SP there
are some good and some not so good IT
espy's out there so choose wisely
another option is to use a broker North
Florida communications act as a broker
for many of our customers we buy
wholesale service from several different
IT SPS
and then route them accordingly to our
customers equipment this allows us to do
the technical work that most of our
customers do not wish to do themselves
and it gives our customers a single
point of contact for their telecom needs
the itsp will in fact become your phone
company your phone numbers will come
from the itsp inbound and outbound calls
will go through to itsp
so let's say someone calls you from
another business once they dial your
number their telephone company will
connect to your I TSP your teeth I TSP
will send a call to your IP address over
the Internet
your router will identify the incoming
traffic as a sip call and will then send
it to your phone system your phone
system will then recognize the number
that it was dialed and send it to the
proper phone or phones let's look at the
process in Reverse and see what happens
when you make an outgoing call you dial
a number on your telephone which is
processed through your phone system the
phone system takes your analog voice and
converts it to digital packets designed
to be sent across the network those
packets are then sent to your router
your router has been properly configured
to prioritize all voice traffic coming
from and going to the phone system the
router takes the voice packet marks it
to be sent to your itsp via the internet
the packet is then routed over the
Internet to the itsp the itsp then
connects back to the public switch
telephone network and since they call to
the proper landline or cell phone why is
it called SIP trunking instead of SIP
lines trunks have more features than
lines and operate in a different manner
plain old telephone service or pots
lines have one phone number per line
each line comes in from a pair of wires
from the phone company for example if
your phone number is five five five one
two three four and someone calls that
number is sent via the public service
telephone network again the PSTN to your
phone company's local central office the
call is instant over a pair of copper
wires to your building and goes to your
phone system your phone system has been
programmed to send all calls coming in
on that line to a certain destination in
our example here it's going to Timmy
now let's say that your manager surely
needs her own phone number you've had an
extra line added with the number five
five five one two five six if someone
needs to call surely they dial that
number and then the call goes to your
phone company and it's sent via another
pair of wires to your phone system and
then that calls around the shearling
so if pots lines you need a pair of
cables for each number or line that you
have if you want for individual or for
different departments to have a private
number you'll need four separate lines
if you also want to have four lines in
the hunt group for general business
calls you'll need four more lines since
each line takes the cable pair you've
now occupied a total of eight cable
pairs or sixteen wires from the phone
company to your building those wires
cost money to install and maintain
that's one of the reasons that SIP
trunking can be cheaper than traditional
phone service now let's take a look at
the same scenario using SIP trunks
remember SIP trunks have more features
than lines and operate in a different
manner SIP trunks use D ID numbers di D
stands for direct and/or dial di numbers
are not line dependent they do not need
a unique pair of wires from the phone
company
for each number that you have instead
they are sent with signaling information
so that your phone system theirs what
number was dialed for instance let's say
someone calls Timmy's private number and
your company is using SIP trunks once
they dial five five five one two three
four that numbers rather from their
phone company to your itsp
who didn't sends the call via the
Internet to your phone system your phone
system is then able to tell that the
coen party dialed five five five one two
three four and that's been programmed to
go to Timmy's phone now someone else
needs to call Shirley they call her
private number five five five one two
five six that call is routed to your IT
SB who says the call via the Internet to
your phone
system then that fall system routes that
call is surely your fall system may only
be configured to accept forcep trunks
you can have as many D ID numbers as you
won't rallied over those four sets for
instance using our previous example you
can have four direct numbers four key
employees and the main number for your
business this calls can all be routed
over the same four SIP trunks now in
this scenario you're limited to four
concurrent calls but you don't have to
pay for an expensive line for each
number that you want to have you just
have one pipe the internet produces two
calls to come in a problem
now let's take a look at something else
we can do with SIP trunks let's say your
main office is located in Jacksonville
but you want to have the presence in
other cities perhaps you have employees
who work in the seas but you want all
calls rather at the de Jacksonville
office you would have a D ID number for
local calls coming from the Jacksonville
market those calls would be sent to your
I TSP who would then send the calls via
the internet to your phone system the
phone system will be programmed to
display Jack's call whenever somebody
calls that number with SIP trunking we
can assign phone numbers from different
cities so the further example let's say
er your company also has a Gainesville
number whenever somebody calls
Gainesville locally the call is routed
to your I TSP who sends it to your phone
system the phone system since the call
to their proper phones and displays
Gainesville in the LCD displays so that
your employees know where the call is
from and how to handle it properly we
can also assign numbers from different
states you could have a number in
Atlanta that is sent to you just like
you're in state and local calls are you
can also have a number from a different
country perhaps your company does
business in the Caribbean someone one in
the Bahamas could call your company from
a local Nassau number and that call
would be routed accordingly
let's look at numbers for advertisements
another good use of the ing number it
says the ability to see which ads are
working with the low cost of D ID
numbers we can assign different numbers
to each ad campaign campaign for example
let's say 5 5 5 2000 is the number of
the peers on your website
whenever someone dials that number the
call is routed accordingly and the LCD
screen on your phone displays website
let's assume that your business still
uses the Yellow Pages we could assign
another number such as 555 2 0 0 1 for
that ad whenever someone funds you and
the Yellow Pages it gives you a call
you'll know from the display the phone
that they found you in the Yellow Pages
perhaps you also have a radio ad a third
number can be assigned for that campaign
and you can know exactly who's calling D
ID numbers are cheap but advertising is
not so SIP trunking with the ID numbers
can help you see where your marketing
dollars are working best other
advantages for SIP trunking include low
costs for all types of calls including
local long-distance and international
new phone numbers can be often acquired
in the same day there's no need to wait
for the phone company to process your
order assign an installer who didn't has
to work new cable pairs to your billing
and then wait for your phone vendor to
connect those lines it's all done
through programming 911 numbers are
assigned on a per D ID basis so if you
have remote offices who are tied back to
your phone system they're not one more
calls will be associated to the proper
address instead of the location of your
phone system now if you've ever had to
move across the street or across town
you probably know what a headache it can
be to get the phone cutting to move your
lines with SIP trunking you'll just need
to make sure you have an adequate
interconnect internet connection working
at your new location your system can
then be relocated without having the way
on the local carrier your technician
will just do a few programming changes
and
everything will be right back up now
what happens if the internet goes down
it would be the same as if the cable
feeding your current phone service was
cut you wouldn't have any service your D
ID numbers however can be individually
assigned to automatically forward to
another destination if your Pollin
system is not reachable via the internet
calls can then be routed to a cell phone
we're back to a back up pots line a
regular phone line from the phone
company
depending on how critical your phone
lines are to your business you may
consider having a back up internet
service from another provider with low
prices of Internet service now back up
Internet is definitely worth considering
if it's available in your area
backup is important not only for SIP
trunking but for your other and it needs
as well today's modern office is more
and more dependent on the internet for
many things you want to get service from
two separate providers like the cable
company and the phone company you'll
need a router that connects up to
Internet or when connections and have it
properly configured in this example
calls to normally be routed to go
through the cable company's internet
service if something goes wrong with the
cable company service calls can then be
automatically routed to the IP address
of your telephone companies internet
service calls will continue to be routed
through to back up internet service
until the primary internet service is
restored calls who didn't be routed back
to the primary connection automatically
this setup makes the trunking more fault
tolerant than traditional phone lines
with traditional phone service you would
simply have to wait until repair
technician restored your service or if
you're lucky someone from the phone
coming may be able to call for jamayne
number two your cell phone
that does it for this presentation I
hope you've learned a little bit about
SIP trunking and the benefits that can
provide for your business if you're in
the North Florida area please let us
know if we can help you with your
communications needs
