Now, let’s take a look at 17.8,
|
|
0:00:16
|
Caller ID Blocking with SIP and Skinny Phones.
|
|
0:00:20
|
We’re told to ensure that any Skinny phone callers
|
|
0:00:24
|
that wish to block their caller ID may do so
|
|
0:00:27
|
by prefixing their dialled number
|
|
0:00:29
|
with the pattern of *67
|
|
0:00:33
|
to ensure that regardless of where a call originates,
|
|
0:00:37
|
that all calls made out to the PSTN emergency number of 112
|
|
0:00:42
|
that were not prefixed with a 0 trunk code
|
|
0:00:46
|
only have their calling name hidden from the PSTN receiving phone.
|
|
0:00:53
|
And to ensure that regardless of where the call originates,
|
|
0:00:56
|
that all calls made out to the PSTN emergency number of 112
|
|
0:00:59
|
that were prefixed with the 0 trunk code
|
|
0:01:02
|
have both their calling name and caller ID hidden
|
|
0:01:06
|
from the receiving PSTN phone.
|
|
0:01:10
|
I need to see if I can get my
|
|
0:01:19
|
Cisco IP communicator to pull up here
|
|
0:01:30
|
so that we can see what the PSTN sees.
|
|
0:01:53
|
So, now, we’re going to first just place a call
|
|
0:02:01
|
from anyone of these phones out to 112.
|
|
0:02:11
|
Oops, I hit the wrong phone. There we go.
|
|
0:02:15
|
So, go off hook and dial 112
|
|
0:02:22
|
and we see that we only see the number.
|
|
0:02:26
|
Let’s take a look, it’s very possible that I
|
|
0:02:30
|
will pull this over just so I don’t give it away.
|
|
0:02:33
|
Do show run type to section voice 1.
|
|
0:02:39
|
Yes, I forgot to get rid of that from the start up config.
|
|
0:02:50
|
I wrote myself a note to do that.
|
|
0:02:54
|
So, let’s try this again.
|
|
0:02:58
|
Desmond places a call to 112
|
|
0:03:04
|
and we see from Desmond Hume at his DN.
|
|
0:03:08
|
Also, if we call from Desmond to 0112,
|
|
0:03:14
|
we also see from Desmond Hume.
|
|
0:03:20
|
So, the way to deal with this is really quite simple
|
|
0:03:23
|
and I already had it configured. Forgot to pull it out, but it’s done now.
|
|
0:03:27
|
We’re going to, first,
|
|
0:03:30
|
let’s do show run type to section voice1.
|
|
0:03:35
|
Actually, I shouldn’t have done that.
|
|
0:03:38
|
We’ll clear that away. One space.
|
|
0:03:42
|
Here’s my fax dial-peer to just 112
|
|
0:03:46
|
and we’ll also do it to fax dial-peer 2 which is 0112, the trunk code.
|
|
0:03:53
|
We’re gonna go into dial-peer voice 1 and we’re simply going to say,
|
|
0:04:01
|
we’re gonna simply issue the command of CLID
|
|
0:04:06
|
caller ID strip and we can either strip name
|
|
0:04:13
|
or restrict the name if the progress indicator is restricted.
|
|
0:04:21
|
So, actually, carry through with that.
|
|
0:04:24
|
We can give a reason or we can just say enter.
|
|
0:04:30
|
We were told in this task that if they dial 112 that is not
|
|
0:04:36
|
prefixed with the 0 which is the dial-peer we’re on,
|
|
0:04:39
|
only and the keyword there have only their CNAM hidden from the PSTN receiving phone.
|
|
0:04:46
|
So, we want to strip name.
|
|
0:04:49
|
We look back at show voice 1 dial-peer.
|
|
0:04:54
|
we see that CLID strip name is what shows up.
|
|
0:04:59
|
So, let’s try the call.
|
|
0:05:06
|
Let’s show our phone as well. I’m just dialing 112.
|
|
0:05:12
|
I did not dial the 0 and the number is still there
|
|
0:05:16
|
but the name is gone.
|
|
0:05:22
|
Now, if we go into dial-peer 2
|
|
0:05:30
|
which as we know is the 0112
|
|
0:05:34
|
and we also do caller ID strip name
|
|
0:05:37
|
bu we also do Caller ID strip
|
|
0:05:41
|
Now, we'll look a that again.
|
|
0:05:43
|
We see that this one contains both
|
|
0:05:46
|
caller ID Strip ang caller ID main.
|
|
0:05:52
|
Not if we look at dial-peer voice one,
|
|
0:05:54
|
it only has strip name.
|
|
0:05:57
|
So, one strip number and name which is the 0 trunk.
|
|
0:06:01
|
The other one only strips name.
|
|
0:06:05
|
So, let's try to call again.
|
|
0:06:08
|
This time we'll dial 0112
|
|
0:06:12
|
and received shows that's in an unknown number.
|
|
0:06:16
|
So, when we dialed 0112, it stripped both.
|
|
0:06:20
|
When we dialed just 112, it only stripped the name,
|
|
0:06:27
|
It did not strip the number.
|
|
0:06:36
|
We were also told to provide a global method whereby
|
|
0:06:43
|
people could strip their caller by dialling *67.
|
|
0:06:48
|
This is caller ID and we can say caller ID name only.
|
|
0:06:52
|
That’s actually the default which is to allow the name for display.
|
|
0:06:59
|
Caller ID block
|
|
0:07:02
|
and code and we’re gonna use *67.
|
|
0:07:07
|
I believe this is where it was getting
|
|
0:07:10
|
confused with the *61
|
|
0:07:13
|
for the night service earlier because it remembered the *67
|
|
0:07:17
|
but we’ll test that in a bit.
|
|
0:07:19
|
Alright, so, now,
|
|
0:07:21
|
let’s first have Desmond call over to Locke
|
|
0:07:25
|
by going off hook and dialing *67.
|
|
0:07:32
|
Now, this shows
|
|
0:07:36
|
not working right now. Let’s
|
|
0:07:40
|
recreate all the CNF files.
|
|
0:07:51
|
Have those phones restart.
|
|
0:07:56
|
We may need to reload the router
|
|
0:07:59
|
as this is the second experienced trace back error we had.
|
|
0:08:16
|
Everything is reloaded.
|
|
0:08:19
|
Let’s try the call again.
|
|
0:08:25
|
It’s not working. So,
|
|
0:08:28
|
gonna reload the router and we’ll come back and we will
|
|
0:08:32
|
test these pieces as soon as we finish reloading the router.
|
|
0:08:41
|
I should probably make sure the system is written first.
|
|
0:08:44
|
I would normally ask you but just to be safe.
