🔌 Configuring Trunks and Zones for Cisco CMR with Expressway

This paragraph explains the initial setup for integrating Cisco CMR with an existing Expressway system using MRA. The focus is on establishing SIP trunks and zones between the Call Manager (CCM), Expressway C, Expressway E, and the Internet. Key points include enabling SRTP for secure transmission, setting up a standard SIP profile with BFCP, and creating a hidden SIP trunk for MRA purposes. The speaker suggests that the port number for the Call Manager should differ from the standard 5060 to accommodate the MRA's hidden trunk. Additionally, the paragraph covers the configuration of the Expressway C and E, emphasizing the importance of encryption through digital certificates for the traversal zone.

05:06

🛡️ Enhancing Security and Routing with Expressway and DNS Zones

In this paragraph, the discussion continues with the configuration of security profiles and routing rules for Expressway. It addresses the potential need for a separate traversal client and server for encryption purposes, although the speaker notes that the existing traversal zone with MRA is already secure. The speaker then moves on to describe the setup of zones pointing back to the Expressway C and E, including the use of TLS verification for secure communication with the Internet. The paragraph also covers the configuration of SIP route patterns for handling WebEx calls and the process of dialing into scheduled meetings using a nine-digit number string. The speaker demonstrates how to join a meeting using Jabber and how the system routes calls to the appropriate destinations.

10:08

🔄 Transforming and Routing Calls in the Expressway Environment

The final paragraph delves into the transformation and routing of calls within the Expressway setup. It explains the use of search rules and regular expressions to direct calls to the appropriate zones, such as the CCM to CMR cloud and the DNS zone for external calls. The speaker details the process of transforming the dialed number string to match the required format for routing to WebEx. The paragraph concludes with a demonstration of how calls are transformed and routed through the system, ensuring that both internal and external calls are handled securely and efficiently. The speaker, Anson Garcia, wraps up the tutorial and invites any questions from the audience.

Highlights

Setting up Cisco CMR with existing Expressways and MRA involves creating SIP trunks and zones.

A trunk is established between Call Manager, Expressway C, and the Internet.

SRTP is allowed in the trunk configuration to Expressway C.

Expressway standard SIP profile should have BFCP enabled.

A recommendation for Expressway SIP trunk security profile is to use a non-secured profile.

Expressway creates a hidden SIP trunk when MRA is enabled.

Port number on Call Manager should be different from 5060 for the hidden SIP trunk to Expressway.

The standard SIP profile should have BFCP and FCPS enabled.

Expressway C's zone points back to Call Manager with a specific port number.

Zone profile should be 861 or above for good interoperability with Call Manager.

Traversal zone to E doesn't require a separate client and server for encryption.

DNS zone for the Internet has TLS verification ensuring encryption.

SIP route pattern is set for WebEx.com with a simple wildcard.

Scheduled meetings use a dialed number string instead of a room.

Route hunt uses a steering digit and wildcards to direct calls to Expressway.

Jabber client demonstrates dialing into a meeting using the number string.

Personal room access uses the SIP route pattern to connect to WebEx.

Transforms are used to adjust the call routing from the number string to the appropriate format.

Search rules and transforms are crucial for routing calls to the correct destinations.

Transcripts

okay hi this is going to be a brief

explanation on how

setup Cisco CMR with you're already

running expressways with MRA so let's

get started just a quick rundown here

we're gonna create all these SIP trunks

or zones an expressway between the CCM

expressway C Express 4 E and the

Internet

right so there's a trunk in between call

manager and expressway see there is a

trunk in between expressway C and E and

there's a trunk from E into the Internet

we're going to okay that's it there all

right let's get started

I'm gonna go through some of these are

screen captures and I'll provide you

with this presentation but I'm gonna go

through instead of going on through all

the spring screen captures I'm just

going to take you through them live here

on the screen so the first thing trunk

configuration we need a trunk to

expressway see okay here's my trunk to

expressway see there's nothing fancy

here the thing I think that is probably

needed is SRTP is allowed and

let's see if you have a destination

address it's a cluster that's gonna be

different I just have one I'd be a

little bit different the expressway

standard zip profile just make sure the

profile has BF CP on it and what else

okay let's take a look at this SIP trunk

security profile as well and I'm not

remembering everything but I just got

want to show you guys everything just in

case I I forgot something you'll notice

it on the screen so we have the

expressway non-secured all right oh

that's one thing one of the

recommendations early on I'm not sure if

it's still still required today but is

to make these supports something

different for expressway because

expressway when you enable MRA it

creates a SIP trunk kind of a hidden SIP

trunking call manager so I haven't read

it in the latest documentation but it

used to be when this first came out that

you had to have the the port number on

call manager different than 5060 because

it was already a hidden SIP trunk 5060

that you couldn't see and call manager

that went to the expressway see for the

purposes of MRA so again that's that's

the way I have mine configured and it

doesn't hurt to do it and then let's see

the SIP profile I don't think there's

anything fancy about to sit profile I

don't think there's anything fancy here

just to make sure BF CP is selected and

I think eight six and beyond the FCPS on

the standard sip profile already okay

so next let's go take a look at I'll

show you the trunk one more time

just so you get on video run through

there and again nothing fancy here okay

let's go take a look at the expressway

see and we're gonna look at the zone

pointing back to call manager so this is

my CMR CCM neighbor so you can see my

port number there

fifty sixty five I just showed you on

that sip security profile nothing too

fancy here I think that's it the zone

profile make sure you choose 861 or

above and that already has the BF CP and

things it used to be you had to do a

custom and choose BF CP and a couple

other things but that kind of creates a

you know good interoperability for for

call manager and okay let's go back and

then we're gonna go we're gonna hop to

the trunk or the traversal zone to the e

now so there's some documentation that

says to go create a different traversal

client and server over to the e but I

haven't found out really exactly why

they they talked about encryption and

things like that but this this the if

you already have MRA going again I do

you can push the calls through this

traversal zone already and it is already

encrypted right because we have to set

that up we have to do digital assigned

digital certificates to get this

traversal zone up so in my opinion as a

states now and I'm not an expert at disk

but this is already this is already

encrypted so I don't create another zone

because it's not needed in my opinion

again nothing weird here okay and then

let's hop over to e and let's go to

zones again

I'm gonna look at the zone pointing back

to the sea now there it is right there

and this is your standard stuff when you

set up MRA okay and then let's take a

look at the DNS zone this is the zone

it's pointing out to the internet okay I

do a TLS verify on this particular DNS

zone so the only thing that this trunk

right can can call right now is WebEx

calm and there's a TLS verify on here as

well so everything's encrypted and

that's it so let's go look at the search

rules now so that kind of covers us for

all the trunks and then call routing

let's go to sip route pattern very

simple here just uh while card WebEx

comm I'm gonna point to the trunk the

expressway trunk and then the other

thing I'll show you here is when you do

a scheduled meeting in and I don't think

I have that up but you can do a

scheduled meeting here's a scheduled

meeting you can see that the video

address it's not like a room anymore

it's a it's a it's a dialed number

string a nine digit number string and

then at whatever your domain is alright

whatever the customer domain is so we do

another route pattern in here and it's

our traditional route pattern let's go

to route hunt and we want to go to route

pattern and what I did here is just a

seven some steering digit just grab any

steering digit that you want is the way

I do it and and nine wild cards there

and you're gonna point that to

Expressway obviously choose off net here

we don't want to provide outside dial

tone or anything like that and then we

just let it loose right that's all we do

we've got to send it

/ and then we'll deal with kind of

transforming it over there in expressway

okay so those are the two things that

we're gonna get to get things out of so

let me bring up a jabber client here and

you can see here this is a scheduled

meeting so there's my number and what I

want to do in jabber or what we want our

customers to do right it's just dial

seven that was a steering digit and then

you know this number and I just have it

there I'll just go in like that and you

can see I get right in there okay so and

in the other way if I went to my

meetings and let's see my personal room

there is the other that's the other way

in right if we go into our personal room

and that's when that WebEx comm sip

remember that sip route pattern over

here is gonna catch this guy right there

so I can also do that and everything's

gonna work okay paste that in I'm

missing it hey there and I can tell that

and that's gonna go right in as well to

see that's working okay so what happened

here

when I dialed the number string the nine

digit number string is one other thing

that I have here and that is the

transform

now let's follow the WebEx all the way

through first let's follow that let's

just do one at a time here so let's do

the table plan and we're gonna do search

rules so we saw those search rules where

the route pattern is a call manager and

then we're gonna route this this guy

right here CCM to CMR cloud that's what

I'm calling it

and you can see in here what I have here

I just have a regular expression and

then I basically have you know anything

at anything dot I know it's hard to see

that dot WebEx dot-com and in anything

if there's a port number or something

like that I call managers like to do

that sometimes

you have to add this this guy right here

because you're gonna take it off

so basically we're we're with rather

expressions we're saying hey in between

these brackets or these parentheses here

this is number one this is number two

and then this is number three

parentheses so I'm what I'm doing here

is just saying hey put one and then an @

symbol and then go ahead and put two and

three and see I'm leaving off I'm

leaving this off over here and then stop

and then obviously we're gonna go across

to the e right traversal zone client

all right now once we get it into e

we're gonna catch that guy and we're

gonna go right over to the DNS zone so

there's a named it the same see I got

the same exact guy right here I just

copy and pasted it and then a replace I

do that stop I kick it out to the DNS

zone which we saw earlier all right

that's really it okay and then let's go

back to the C and I take the same route

pad or a same same the same search rules

but before on that on a schedule meeting

where you dial the nine digits I'm doing

one thing here in this little transform

so I'm doing a little transform first so

this just you know nine digits seven and

nine digits come in and then what I do

is I just a little regular expression

again anything with seven that has nine

digits right and then dot anything over

here to catch any port numbers that are

coming across from call me integer and

I'm just you know doing you know put the

one in here the one is remember anything

between the first parenthesis here which

will be the number so we're leaving off

to seven and then just a pend at you

know whatever the customer domain is

WebEx calm alright and that's really it

and then you know after it does this

it's going to catch that same search

rule because it's going to

the transform first and it's gonna come

over here and then grab that search for

one in and then go on so that's really

it that's in a nutshell that's how you

do it's very easy and any questions just

give me huh this is Anson Garcia and I'd

like to thank you for watching
