Because these worldwide deployments can be flat-out overwhelming, the course walks through the design from the ground up. You will learn connecting multiple sites using voice gateways and intercluster trunks, designing and implementing a globalized dial-plan, implementing call processing redundancy, device mobility, and more!

CUCM Multisite: Understanding the Big Picture Design

00:00:00 - Understanding the big picture design.
00:00:02 - Or I think I'd rather call this CIPT2 Series Overview.
00:00:06 - Because that's what this really is.
00:00:08 - We're going to be looking at multi-site deployments and the
00:00:11 - challenges associated with them.
00:00:13 - Now, it makes it a very awkward Nugget to record,
00:00:16 - because I'm going to be going through each one of these
00:00:17 - challenges, like what kind of connections do you bring up,
00:00:19 - quality of service, bandwidth concerns.
00:00:22 - All those kind of things.
00:00:23 - I'm just going to be listing these challenges and not give
00:00:25 - you any solutions, because that's what the rest of this
00:00:27 - series is going to be about.
00:00:29 - So I'm going to say, there's a problem, so we've got to deal
00:00:31 - with that, and then move right on from there.
00:00:33 - So the first thing that we have to think about is, what
00:00:36 - about our connections?
00:00:37 - Let's look at our topology.
00:00:38 - We've got Phoenix over here, which looks like it's got its
00:00:41 - own little call manager-- we'll say
00:00:42 - its publisher server.
00:00:43 - Its own cluster.
00:00:44 - Same thing with Australia.
00:00:45 - It's not a cluster split over the WAN.
00:00:48 - This is another publisher server.
00:00:49 - Completely separate database all together.
00:00:52 - San Diego is using that centralized deployment model,
00:00:55 - so these phones get their dial tone from this call manager
00:00:58 - down here in Phoenix.
00:01:00 - Now if the WAN link goes down, they have some kind of fail
00:01:03 - over that's going to be a little bit of what we talk
00:01:04 - about in this series.
00:01:05 - Actually, a big part of what we talk about.
00:01:07 - This router's going to be needing to run something like
00:01:09 - SRST, survivable remote site telephony, so that way they
00:01:13 - still get dial tone, even if the WAN link is offline, and
00:01:15 - maybe can even make PSTN calls.
00:01:18 - I say maybe because PSTN is now becoming almost optional
00:01:23 - in each one of these locations.
00:01:24 - Kind of, but not really, but sort of is.
00:01:26 - But we'll talk about that.
00:01:28 - So connections means, how do you get all these things
00:01:30 - connected together?
00:01:31 - For example, you want to take Phoenix, which maybe has one
00:01:35 - xxx extension.
00:01:35 - So 1,000 and 1,001.
00:01:37 - All that.
00:01:37 - And then Australia, which is, we'll say 21xx extensions.
00:01:41 - And you want to make sure that these guys can call each other
00:01:43 - without paying the toll charges by going
00:01:45 - over the WAN link.
00:01:46 - How do you do that?
00:01:47 - Well, I mean, there's different options.
00:01:49 - You could say, well, I want to use a SIP trunk to do that.
00:01:52 - Or you might say, well, actually, I'd rather link
00:01:54 - these call managers directly using an intercluster trunk.
00:01:57 - But then someone comes along and says, well, did you know
00:01:59 - the gateways could do that?
00:02:00 - You could actually point straight to that gateway.
00:02:02 - And to do that, you could use H.323, or you could use MGCP.
00:02:06 - And that's always preferred, because Cisco
00:02:07 - developed that one.
00:02:08 - But oh, you can also use SIP as well.
00:02:10 - And then the gateways can point to each other, and they
00:02:12 - kind of manage all your outside dialing plan.
00:02:14 - And then you can throw in a gatekeeper,
00:02:15 - which as you grow--
00:02:17 - I mean, see what I mean?
00:02:18 - It's like, huh?
00:02:20 - Well, OK.
00:02:21 - So you're saying there's a lot of ways to do this?
00:02:23 - Yes.
00:02:24 - Which one's best?
00:02:25 - Well, it depends.
00:02:26 - So that's going to be what we talk about as we go through
00:02:28 - this series.
00:02:29 - Then we drop down into quality of service, which is I know a
00:02:31 - topic that you've all heard about.
00:02:33 - And I will say out of all the topics, we will touch on this
00:02:36 - one lightest in here, because it's actually part of the
00:02:39 - CVOICE series, one of the prerequisite series at CBT
00:02:42 - Nuggets before you would have gotten here.
00:02:45 - However, it's still worth mentioning, because you want
00:02:47 - to make sure that when voice goes across the WAN, and
00:02:50 - there's data traffic, voice always wins.
00:02:52 - That's the whole goal of quality of service, is to
00:02:54 - prioritize some traffic over others.
00:02:57 - But actually, as we bleed between quality of service and
00:03:00 - bandwidth, we'll start talking about another challenge, which
00:03:03 - is, let's say you've got Fred in Australia--
00:03:06 - are there people named Fred in Australia?
00:03:08 - I don't know.
00:03:09 - But Fred calls over here to Sally in Phoenix.
00:03:12 - And then, Beth does the same thing, and Ron
00:03:15 - does the same thing.
00:03:16 - And you start getting all these calls.
00:03:17 - And now it's no longer a voice versus data match, which is an
00:03:22 - easy victor when you set up quality of services.
00:03:24 - It's like data, dum, hits the mat.
00:03:26 - Voice is the one that ends up winning.
00:03:28 - But what do you do when you have voice versus voice?
00:03:33 - The biggest fighter wins, right?
00:03:34 - Whoever talks loudest wins.
00:03:36 - Actually, no.
00:03:37 - As we bleed into this bandwidth control, we'll
00:03:39 - introduce a topic called call admission control, which says,
00:03:42 - OK, I can only have so many voice calls going across that
00:03:46 - WAN before it's just flat out of bandwidth.
00:03:48 - Quality of service is so fun because with voice, you're
00:03:52 - like, oh man, it gets the priority, but it's actually
00:03:54 - called strict priority, which means if voice ever tries to
00:03:58 - go above its priority bandwidth limit that you set,
00:04:02 - it's like quality of service is like, no go.
00:04:03 - No.
00:04:03 - I'm not going to try.
00:04:05 - I don't care if I have 1,000 megabits per second sitting
00:04:07 - there idle.
00:04:08 - You're dead voice.
00:04:09 - You're not getting any further, which is kind of fun.
00:04:12 - And that's where call admission
00:04:13 - control becomes essential.
00:04:14 - So we're going to look at bandwidth control as a big
00:04:17 - picture for that.
00:04:18 - Now, when you're talking about bandwidth control, let me get
00:04:20 - rid of all this gibberish here, bandwidth control says,
00:04:23 - I want to effectively use my resources.
00:04:26 - For example, let's say that we have Sue over here in San
00:04:29 - Diego talking to Beth on the phone.
00:04:34 - And Sue says, oh, hang on one second Beth, and presses the
00:04:37 - Hold button.
00:04:38 - Well, I don't know about you, but I don't see any music on
00:04:42 - hold at juke boxes sitting in here in San Diego where it's
00:04:45 - like, oh, this mystery box starts sending music notes
00:04:48 - down to Beth.
00:04:49 - No.
00:04:49 - What happens in a centralized deployment is this guy is the
00:04:52 - music on hold server.
00:04:53 - We talked about that in the CIPT1 Series.
00:04:55 - In the Media Resources, we said, OK, well, one of the
00:04:58 - call managers will be designated as a
00:05:00 - music on hold server.
00:05:01 - And it's going to be streaming.
00:05:02 - So as soon as Sue presses the Hold button for Beth, you're
00:05:06 - streaming music across the WAN link from
00:05:08 - Phoenix over to San Diego.
00:05:10 - There's got to be a better way.
00:05:11 - Same thing, what if we do a conference call?
00:05:13 - We have Sue and Beth--
00:05:15 - and there's more phones here.
00:05:16 - I just didn't draw them.
00:05:18 - And Joe, and Bob, all these people jump on
00:05:21 - a conference call.
00:05:21 - Again, I don't see any conference bridges other than
00:05:25 - Phoenix over here.
00:05:26 - Conference bridge, media resource.
00:05:27 - So all these guys start hopping down here to Phoenix.
00:05:30 - You're having a conference call over the WAN link, when
00:05:33 - all the people on the conference call are
00:05:34 - sitting in San Diego.
00:05:35 - Again, not a good use of bandwidth.
00:05:37 - So we'll look at how we can circumvent
00:05:39 - those kind of things.
00:05:40 - Now, dial plan.
00:05:41 - Oh, my word.
00:05:42 - If there is a concept that is probably more complex than any
00:05:45 - of them, this would be it.
00:05:46 - When we went from the PBX world to the voice over IP
00:05:50 - world, it just exponentially became complex.
00:05:54 - Because in the PBX world, you essentially said, I have one
00:05:57 - exit point.
00:05:58 - It is the PSTN.
00:05:59 - Maybe you had an analog backup or something to the T1, which
00:06:03 - added a little complexity.
00:06:04 - But now, I mean here's our goal.
00:06:05 - Let's say we've got, going back here to Phoenix, 1xxx,
00:06:08 - and we've got 21xx.
00:06:10 - And both of these locations, Australia and Phoenix, have a
00:06:13 - good T1 line to the PSTN.
00:06:16 - That's their PSTN access.
00:06:18 - But I don't want to pay the long distance to call between
00:06:22 - my offices over that.
00:06:23 - So when I dial 2102, which is this phone right here, it's
00:06:28 - going to go over the WAN, which I want.
00:06:29 - But what happens if the WAN is down?
00:06:32 - Then do I just lose Australia calling?
00:06:34 - Do I have to now send out a notice to the company?
00:06:37 - Email, hey FYI, WAN link down.
00:06:40 - Everybody dial international numbers to reach Australia
00:06:44 - now, because the WAN link--
00:06:46 - oh, no, it just came up.
00:06:47 - Email.
00:06:48 - No.
00:06:48 - No, what we want is we want this set up to where when I
00:06:51 - dial 2102, and call manager's like, oh, I know
00:06:54 - the WAN link is down.
00:06:56 - I'm going to automatically transform that number into the
00:06:58 - valid PSTN number.
00:06:59 - You know, stick on 011, and then country code.
00:07:02 - I mean, I'm talking United States dialing plan here.
00:07:05 - But you transform the number to go across the PSTN.
00:07:08 - And there's no way I'm going to show 1010 as the caller ID,
00:07:13 - because that doesn't work over the PSTN.
00:07:15 - So I also want to transform that caller ID to work across
00:07:17 - the PSTN as well.
00:07:19 - You see what I mean?
00:07:20 - Now, OK.
00:07:21 - You're like, OK, I can hang with that.
00:07:24 - I'm following that.
00:07:25 - You go, well, I want to introduce also a topic called
00:07:27 - TEHO, tail and hop off, which says, you know what?
00:07:30 - I bet it's a lot cheaper for Australia to
00:07:33 - call Australia numbers.
00:07:34 - And it's a lot cheaper for Phoenix to
00:07:36 - call Phoenix numbers.
00:07:37 - Right?
00:07:37 - So why don't I set this up to where, for instance, when
00:07:40 - someone in Australia dials--
00:07:41 - I don't know what they dial for an
00:07:43 - international number in Australia.
00:07:45 - I'll just say 1-602, because it's what we dial here in the
00:07:47 - United States.
00:07:48 - 555-1111, which is a number out here in Phoenix, because
00:07:53 - we have the 602 area code.
00:07:55 - Well, why not instead of just paying that toll charge to
00:07:58 - call that, why not route that across the WAN to Phoenix, and
00:08:02 - then Phoenix can send that out to the PSTN, and I don't pay
00:08:05 - any toll charges at all.
00:08:06 - And the bigger and bigger my company grows, the more
00:08:08 - locations I get all around the globe, the more free stuff.
00:08:12 - It's kind of like, woohoo!
00:08:14 - As we grow, we got all these expenses.
00:08:15 - But you know what?
00:08:15 - At least we get free long distance to whatever
00:08:18 - area that that is.
00:08:19 - That's called tail end hop off.
00:08:20 - And then you say, well, but I only want certain people to be
00:08:24 - able to dial that.
00:08:24 - I don't want everybody to be able to dial those numbers.
00:08:26 - Maybe partitions and--
00:08:28 - [WHOOSH].
00:08:30 - That was my head.
00:08:31 - It just exploded.
00:08:32 - Seriously, that's the dial plan
00:08:34 - complexity that we get into.
00:08:35 - But I will say once you get through the dial plan Nuggets
00:08:39 - that are going to be part of this series, you're going to
00:08:41 - have the knowledge necessary to create that
00:08:43 - crazy complex outline.
00:08:45 - And this is a whiteboard on my whiteboard.
00:08:47 - Because a whiteboard is required for this.
00:08:50 - It's seriously one you will spend hours on.
00:08:53 - And you'll sit there and go, OK, well, if this person dials
00:08:55 - here, then this, and then this.
00:08:56 - But the fun thing is, after this series, you're going to
00:08:58 - have the knowledge to do it, to where it becomes like
00:09:00 - putting together a fun jigsaw puzzle rather than
00:09:03 - Googling for hours.
00:09:04 - And Bob just advised me wrong, and now I have
00:09:08 - to do it all over.
00:09:08 - I mean, you don't want to do all those things.
00:09:10 - So the dial plan is a big part of what we're
00:09:13 - going to talk about.
00:09:13 - Availability, we already talked about that.
00:09:15 - That's keeping the site running.
00:09:16 - Should it go down, you have SRST, survivable remote site
00:09:19 - telephony, to do that.
00:09:20 - And you can even run it in Call Manager Express Mode.
00:09:24 - And what that is giving SRST more features, more ability,
00:09:29 - than the base SRST feature set.
00:09:34 - And then, finally, mobility.
00:09:35 - Mobility is what happens when people move.
00:09:37 - Now, that's one of the beauties of this voiceover IP
00:09:40 - phone system, is you just unplug the phone and move.
00:09:43 - But that also creates a little chaos when somebody grabs
00:09:47 - their phone and flies to Australia, and then dials an
00:09:49 - emergency number, and then all the calls end up here in
00:09:53 - Phoenix, and all that kind of stuff.
00:09:54 - So we're going to talk about device mobility.
00:09:55 - We'll talk also about extension mobility.
00:09:57 - That's kind of like roaming profiles, to where somebody
00:10:00 - can log into a phone here in Phoenix, and then they don't
00:10:02 - have to bring their phone with them.
00:10:03 - They just walk, or fly, to Australia, and then log into a
00:10:07 - phone here.
00:10:07 - And their whole profile, their whole phone, kind of follows
00:10:10 - them along.
00:10:12 - These are the considerations that we need to have in mind
00:10:14 - as we move forward with a multi-site deployment.
00:10:16 - All that to come in this series.
00:10:18 - I hope this has been informative for you.
00:10:20 - And I'd like to thank you for viewing.
