So we're going to add another writer to the.
Now I've configured this Rada with coal managing Express.
And I've got a Cisco IP communicator which is essentially a soft phone that mimics a seventy nine seventy
Cisco IP phone that's running on my laptop and I'm going to demonstrate setting up calls between the
U.S. 500 and this route.
So from my analog phone 1000 we should be able to make a call across the IP infrastructure to this IP
communicator and we should be able to make calls from the IP communicator back to the analog phone.
So here's my IP communicator and you can see it's got a telephone number of two thousand.
I'm gonna change the skin so that you can see more clearly what's going on.
So I'm going to change it to compact mode.
And there you go.
There's my IP communicator and I can go fuck and I'll be able to hear Dalton if I try and dial 1000
I immediately get a fast busy tone because this writer doesn't know where 1000 is so we have to configure
the U.S. 500 to know about router 2 and we have to configure out it to to know about the U.S. 500 so
that calls can be made between these two devices.
The default signaling protocol used on VoIP dial peers is a two to three with H3 these three the devices
are independent of each other.
So the DOL plan on the U.S. 500 is totally independent of the DOL plan on write it to we have to configure
the routers independently to allow them to call one another.
So let's do that.
We'll start off with the configuration of the U.S. 500.
So I'm going to tell it to the U.S. 500
and log in
topping the command show dial Desh peer voice summary shows us that we only have a dull plan for two
analog phones and our connection to the PSTN.
So to create a dollop here to get to write it two are going to global config mode.
And I'm just going to choose the next number.
So dial the HP a voice for and notice now I'm going to specify VoIP I'm in a specified destination pattern
and there are a lot of options here.
Let's say for instance router to has telephone numbers 2000 to 2009 to reference those numbers on the
U.S. 500.
I could specify two followed by three dots.
But notice that covers the range two thousand two to Triple Nine.
Each dot represents a single digit wildcard.
I could also do this that represents the digits 2000 to 2009.
So that would work and is probably a better choice but to show you some of the other options I could
also use square brackets and then specify a range of let's say 0 2 9 and that would also work just to
explain the brackets please note this only consists of four digits or four numbers the first number
or digits to the second digit is zero.
The third digit is zero.
And the fourth digit is in the range 0 1 to all the way up to 9.
So this would also work.
There are different wildcard bits available in the destination pattern salacious use that to prove that
it'll work and not specify what's called a session target.
Now this gets quite confusing because it asks you to put in a string.
You have to remember to top that come on IP the for colon and then specify the IP address of the remote
Radha which in this case is rather too with that IP address.
That's good practice to prove that we have IP connectivity between the road is and you can see there
we don't just check the routing table and that default Rod is wrong.
So I'm going to change that.
Let's see if we can ping again.
And as you can see there the ping was successful so now let's prove it.
I've only configured one side of the connection.
I've only configured the U.S. 500 I haven't configured this Rada with a VoIP yet.
Back again now to prove that lets tell it to the Rada So tell me to write it to
show.
Dial dash peer voice summary at first glance this gets a little bit confusing.
Notice the destination pattern is 2000 and 2001 with a dollar sign dollar sign would force the use of
this specific dollar here.
Notice the tag is twenty thousand one and twenty thousand eighty so it would force the use of this dollar
bill it's a twenty thousand one.
If you dialed two thousand and they were to double up is with the value of two thousand.
So in other words two thousand dollar is chosen above 2000.
It's a way to force calls to go to a specific dollar.
Here I'll explain more details in a moment.
But for now notice that there are no VoIP dollar is on this Rada only Potch is.
So what I'm gonna do is I'm going to make a call from 1000 to 2000 the IP communicator is registered
to this Rada the analog phone is connected to this rather market communicator on the analog phone.
I'm gonna go fuck and dial two thousand
as you can see they we have an incoming call from 1000 which I can now answer
and disconnect
so we have successfully been able to make a call from this analog phone to this IP phone can we call
back again.
So on the IP phone I'm going to go fuck and I'm going to try and dial 1000
and the call fails.
The reason why is this Rada does not know what to do if it receives a call to the 1000 range.
So we have to configure out a TI to send calls back to order 1 and write at 2.
I can go into global conflict mode credit default here.
That said Dolby Voice 1 VoIP destination Patton and let's say we only want to specify those two individual
analog phones
so I could use that option.
The first digit must be a 1 the second digital 0.
The third digital 0 and the fourth digit either is 0 or a 1 session target ITV 4 and the IP address
of the U.S. 500 is 10 1 1 2 and now let's try and make a call so go fuck dial one thousand
and as you can hear there the phone is ringing
It's try one thousand and one
and as you could hear they call it successfully setup OK.
Let's expand the network and add IP phones to our U.S. five hundred.
So we gain a connect to IP phones to the inline powered ports on the U.S. five hundred U.S. five hundred
X as a router and a switch and a Cisco Unified Communications Manager Express and voicemail device all
in one so equal provide power to these IP phones.
So we're going to configure to IP phones one with a telephone number of 1002 and another with a telephone
number of 1003.
So we will now have two analog phones as well as two IP phones on the U.S. 500.
We are still connected to the PSTN on our ethics O port and we still connected to the IP network on
one of the Ethernet ports which gives us connectivity to rout it too which has a Cisco IP communicator
registered to it at the moment so I'd like to go through the configuration of these two IP phones from
the very beginning.
So there's a number of things that we need to configure including inline power the lens the HP TFT IP
the SIU CMC or unified communications manager Express.
And I'd like to show and then explain the hidden doll pictures that are created when you configure Ethan
headphones on see you CMA so as discussed the first thing an IP phone requires is power and we are going
to use inline power to provide power to this phone.
So typical real world implementation would have a P.C. connected to an IP phone connected to a switch
and then power would be provided either using Cisco's power of the Ethernet or the industry standard
attitude or three if in our example the U.S. 500 has a built in switch which is going to provide power
to the phones so tell netting you might U.S. 500
I can top the command show power in line and that will show me if firstly we are allowing power to be
provided on a port.
In other words it's set to auto as in this example or we've turned power allocation or so on these ports.
0 2 7 we have left the power setting at default which is auto.
Remember you never turn power on it's either auto or you can't set it to on because if you plug the
P.C. in that could blow the nick of that piece and you don't want to allocate power at the moment you
can see the power allocated is 0 watts.
That's because we have no IP phones plugged into this.
You see 500 I can talk to come show CTP neighbors at the moment you'll see this just one neighbor Arata
with this name and it's an 8 5 7 Cisco Radha so as per our diagram let's plug in two phones on the second
and third ethernet port so hopefully we should see power allocated on port if 0 1 1 and it's 0 1 2 and
we should see those phones 3 DP neighbors
you have to type 2 month to see what's going on now as you can see they interfaces were changed to down
and then to up
topping the command showed power in line once again shows me that we're using Ada 2 to 3 AAF because
it's I triple E device top three and we can see the amount of power that's been allocated to these devices
I'll do that come on again and you can see once again that power is being allocated shows GDP neighbors
shows me suddenly two neighbors in addition to the Rada.
It also shows you that these are IP phones.
Now notice the name ACP stands for Celsius Ethernet phone because Cisco purchased the company Celsius
and the phones they're manufactured so it's Celsius.
Ethan at phone followed by the MAC address of the phone and you can see the local interface and the
port on the phone that's used so port one on the phone is used to connect back to the switch or in this
case the U.S. five hundred so we have completed the first step we have got power to our IP phones.
