Voice lab setup

Hi,
I have a router 2811 and wanted to create a voice lab with max 5 ip phones.So i wanted to know what are the minimum devices and modules required for voice lab.I have read in a document stating that for voice requirement are
two cisco router,two pvdm2-32 and two vic2-2fxs and two vic2-2fxo .
What else do i need ?Please help

CCNP Voice Lab - What to buy?

Hi folks,
I've been searching the web for some examples of a voice lab, however to me it's unclear on exactly what I need. Do you mind taking 5 minutes to help me out?
I've already got a lab using ESXi, CSR1000v a couple of PIX 515's and a POE switch along with 6 x 3750's. I've got several 2621XM on a shelf that could be restored with 64MB of Flash and 256MB of RAM. I've also got a 2851 but with no RAM or Flash. Plus 2 IP Phones.
What I'd like to do is build a voice lab that allows me to setup CME and to simulate calls going across PSTN (to simulate WAN failover). I imagine I'll only need two physical routers, the rest can be done within ESXi using CUCM with CIPC's, unless of course the IP Phones are required when the site is running CME.
I want to simulate a company that grows from single site, to multiple site centralised CUCM, then build a de-centralised cluster then move to a cluster to cluster over the WAN. Working this way with a goal helps me learn rather than reading books/watching videos.
What cards/routers/cables do I need?
many thanks
Dave

Thanks afmmanicke,
Which of these cards however do I need and why?
I've seen that the following versions of CME are available, for studying what do you folks recommend?
8.6 - Cisco 28XX
4.1 - Cisco 2621XM
I'm leaning towards 8.6 but for CCNP Voice not sure if it's overkill or 4.1 is not enough. Version 8.8 and above requires 29XX which is out of my budget.
thanks
Dave

Lab setup multiple SIP domains for federation

I have been setting up multiple Lync 2013 lab environments and have a question about my external DNS environment. I have installed server 2012R2 on the host running the lab with its own domain (contoso.local). I have this server which hosts a separate domain,
Hyper-V and a CA, this is what I am using for my external environment. The network IP is 10.0.0.0/16.
I set up a server called vRouter that has 3 NICs. In Hyper-v I have 3 virtual switches configured. One for the External environment - 10.0.0.0/16 (not necessary for lab, setup to transfer needed files from internet to VMs), one for 192.168.1.0/24, and one
with 192.168.2.0/24. The virtual router has RRAS installed and can route traffic between 192.168.1.0/24 and 192.168.2.0/24.
My VMs for the lab are as follows.
1test.local
AD1.1test.local -192.168.1.100
FE1.1test.local - 192.168.1.200
Edge1 - 192.168.1.210int, 10.0.5.10ext
2test.local
AD2.1test.local -192.168.1.100
FE2.1test.local - 192.168.1.200
Edge2.1test.local - 192.168.1.210int, 10.0.6.10ext
Both environments have users that can log into lync and message each other.
When installing the Edge servers I used the same FQDN and IP for the external interface since all ports are open and firewalls have been disabled internally. I installed the internal certificate from the AD server which has CA role in each environment. On
the external device I used the Host's CA to get certificates for both Edge servers. The Edge servers have 2 NICs one on their expected internal environment with no Gateway. And one on the external environment. These servers are not part of any domain. however
I did add the contoso.local to the primary DNS suffix when domain membership changes under system properties. I then created the two following A records on the host computer (10.0.0.0\16 network, contoso.local) to be able to see router their external traffic.
Edge1.contoso.local 10.0.5.10
Edge2.contoso.local 10.0.6.10
Both of these FQDNs are what is in my topology for the Access Edge service, Web Conferencing Edge Service, and A/v Edge Service with the same IP using different ports in both environments.
Both environments are set up to support the other SIP domain. However when I try to add a user from the other domain I cannot communicate with that user nor see their presence.
I looked over my external DNS settings and realized that I had not set a SRV record on the 10.0.0.0\16 network(external).
I then realized that if I try to add the traditional _sipfederationtls._tcp.contoso.local I will have 2 conflicting entries.
One for:
_sipfederationtls._tcp.contoso.local - 10.0.5.10 (1test.local edge)
and one for:
_sipfederationtls._tcp.contoso.local - 10.0.6.10 (2test.local edge)
Should I spin up another VM and make that a DC with a CA and trust it to the host computer, set up conditional forwarders. Something like Trust.local and correct the DNS, topology builder FQDN, and certificates on the second edge server?
Edge2.trust.local
Or can I add a new zone to my host computer then correct the DNS, topology builder FQDN, Certificates?
Or am I missing another external DNS record on my contoso.local environment?
Can I set up a CNAME entry that will mask the second edge server?
Any input would be appreciated.
Thanks

If contoso.com is not a sip domain, then you won't need that DNS record at all. Those records are autodiscover records that Lync uses based upon the sip domain.
So you'd need
_sipfederationtls._tcp.1test.local
and
_sipfederationtls._tcp.2test.local
What effectively happens, is when someone on the outside tries to IM
[email protected], their Lync edge server will see the 1test.local and query the appropriate above record for it so it knows where to communicate.

Exchange Server 2013 - Lab setup with internal emails only

Hi,
I'm new to Exchange Server 2013. I've started a POC on the product by setting up a Lab environment with one 1 AD server and 1 Exchange server (Both Windows 2012 R2). As this is a POC I just need the internal email communication. I don't want the mails to
go over the internet.
I've completed the installation part and just started to configure Send/Receive connectors and got stuck with the question whether the connectors are required or not.
Could someone please help me out in configuring internal email setup for Exchange 2013 lab setup.
Regards,
Nithin

Hi,
You need not to configure send/receive connectors for internal email.
The following article for your reference:
http://technet.microsoft.com/en-us//library/aa996395(v=exchg.150).aspx
Default Receive connectors created during setup
Certain Receive connectors are created by default when you install the Mailbox server role.
Default Receive connectors created on a Mailbox server running the Transport service
When you install a Mailbox server running the Transport service, two Receive connectors are created. No additional Receive connectors are needed for typical operation, and in most cases the default Receive connectors don't require a configuration change.
These connectors are the following:
Default <server name>   Accepts connections from Mailbox servers running the Transport service and from Edge servers.
Client Proxy <server name>   Accepts connections from front-end servers. Typically, messages are sent to a front-end server over SMTP.
Each connector is assigned a TransportRole value. You can use it to determine the role the connector is running in. This can be helpful in cases where you are running multiple roles on a single server. In the case of each Receive connector previously
mentioned, their TransportRole value is HubTransport.
To view the default Receive connectors and their parameter values, you can use the
Get-ReceiveConnector cmdlet.
Default Receive connectors created on a Front End Transport server
During installation, three Receive connectors are created on the Front End transport, or Client Access server. The default Front End Receive connector is configured to accept SMTP communications from all IP address ranges. Additionally, there is a Receive
connector that can act as an outbound proxy for messages sent to the front-end server from Mailbox servers. Finally, there is a secure Receive connector configured to accept messages encrypted with Transport Layer Security (TLS). These connectors are the following:
Default FrontEnd <server name>   Accepts connections from SMTP senders over port 25. This is the common messaging entry point into your organization.
Outbound Proxy Frontend <server name>   Accepts messages from a Send Connector on a back-end server, with front-end proxy enabled.
Client Frontend <server name>   Accepts secure connections, with Transport Layer Security (TLS) applied.
In a typical installation, no additional Receive connectors are required.

Minimum hardware for 'voice' lab ? - Please answer.

Hi,
I've got (3) C2610's running IP Plus IOS 12.3. I also have (2) Cat 2912XL.
If I want to play with VoIP configurations, how much am I going to miss if I don't have a Layer 3 switch ? I mean, the Cat 3550 is kind of a little expensive for me and therefore I would like to play with VoIP without a layer 3 switch for now, if possible.
Please advise.

Thanks. It is a C2610. I put 64D and 16F and I am running in reality the Enterprise Basic image from the XM platform. The problem is that it is 12.3 and I see that XM's 12.4 don't run on C2610's.
How about the switch ?
Can I practice voice labs (at CVOICE level) and dispense the need for layer 3 switches ?

CCNP Lab setup

Hi Guys,
I've to propose a cisco equipment list to setup a complete lab for "CCNP R&S" course, this lab setup should be able to simulate the entire course contents/theories of the three modules including route, swithc and Tshoot).
So what is the recommended lab setup to met the above requirment? Further we are looking forward to purchase new equipment, rather than considering the re-purbished equipments. Please advise.
Regards,
Suthakar

Depends on your budget, of course.
To cover the switch portion, you would want two 3560 models (3560, 3560G, 3560E, 3560X, depending on how much money you have to burn) and two 2960 models (again, G, PoE, etc) depending on what you're after.
For routers, I haven't finished building my lab yet, but I'd want 1841's or 19xx's. Something that can run 15.x code. I think to really run anything, you'd want at least 4 routers, plus serial WIC-1T cards, serial crossover (DB-60) cables, and at least a 4 port serial module for one router. I'd probably want at least one big router, like a 3845 or 39xx.
I'd probably want 4 18xx/19xx remote site routers, and 1 38xx/39xx hq site router. You can use GNS3 to simulate the routers though really, so most of my focus has been on switches.
Good luck!

Hello,
I have my CUCME 7x running on a 2801 router, with an AIM-CUE daughtercard for voicemail. I have a 3560 switch with PoE, and you can use any phone that the system supports. In my lab I have a couple of 7931's, some 7961's, and 7942's. It works like a charm.
Hope that helped, if so please rate.

Why is the prepay voice mail setup so laborious?

Why is the prepay voice mail setup so laborious? LG Cosmos 3. Hardly ever use as a phone, and rarely get a voice mail. Friend of mine said they left me a voice mail, I go to check it and gotta go thru 3 minutes of voice mail setup before I can even get to a message ? How about letting me bypass name setup, greeting setup, forced to listen to recordings, etc.

Hi Bwhatever,
Thanks for the great feedback! We want checking your voicemail to be easy, and I apologize that this did not occur. You would only need to make one initial greeting setup. Moving forward, when you log into your voicemail, it should allow you to go directly to listening to your unheard voicemails.

Pre-requisite for lab setup for database administration track.

Hi, does anybody know what setup is required to participate in Lab for database administration track on Feb 11?

The code you have in the rules file looks like it is incorrect. PCon would not be defined automatically and would therefore return zero. I think what you are actually looking for is something like:
Call Hs.Con ("",HS.Node.PCon(""),"")
Note that you can determine if the consolidation rules are used from you metadata under AppSettings. Look for the setting called ConsolidationRules. If you set this to Y, it uses the rules under Sub Consolidate(), if you set it N, it will automatically consolidate even if you have nothing under Sub Consolidate().
Further, you can affect what gets consolidated in the metadata. Some of your accounts etc. may not be set correctly. Some things to check:
For Accounts, make sure that IsConsolidated is checked and the AccountType is correct
Also for Accounts, ensure that EnableCustom1Aggr ... is checked
Finally, if the Entities have different currencies, check if you are getting data up to [Parent Total]. If not, the problem is your translation and not your consolidation.

UCCE 9.0.1 Lab Setup Sprawler

Hi,
I am trying to setup ucce 9.x lab as a Sprawler meachine. But when I try to run the UCCE Web admin page, I need to selct a deployment model. It doesn't let me select anything other than PCCE Lab only, which will cut down the configuration options in my lab. Anyone know if I want to use complete UCCE(not PCCE) in lab as a sprawler meachine, how can i do it?
Thanks

Hi Alejandro,
This error will normally come if u try open domain manager without installing the base setup of ICM. try installing ICM base setup first and then run Domain manager. You should not see that issue.
Hope this helps.

Building a Voice Lab

Hi Guys,
Im currently building a lab and looking for any knowledge in what devices i will need.
Im looking to construct 3 seperate networks connected by an MPLS WAN. The networks must be able to communicate with eachother by voice video and also be able to have Music on Hold, Voicemail and PSTN failover. The networks will also need their own CUCM server to maintain redundancy for if the WAN is not available.
Could anyone please tell me what devices i should purchase.
is this design optimum? The topology will be something like this.

Nathan,
My only suggestion would be to see if you can get anyone you know provide the bootable media or download it for you as you can change the downloaded iso to be bootable (many threads on how to do that here) with assumption that it would be just for lab and not production deployment. If your company does not currently have CUCM or you do not know anyone who could provide it to you I don't know of other ways to obtain it.

Standalone ASA Lab setup context disabled

                   I've built a lab with two standalone ASA with no failover unit in firewall router and multiple context mode with failover active setup on each to make them act as primary and to simulate two separate Data Centers and DMZs. When I do a show failover on a context I get the message that shows the context disabled. What do I need to do make the context active on each standalone unit?
asalab03# sho fail
Failover Off
Failover unit Primary
Failover LAN Interface: not Configured
Unit Poll frequency 1 seconds, holdtime 15 seconds
Interface Poll frequency 15 seconds

Hellom
Have you already assigned a context to one of the failover groups?
hostname(config)#failover group 1
hostname(config-fover-group)#primary
hostname(config-fover-group)#exit
hostname(config)#failover group 2
hostname(config-fover-group)#secondary
hostname(config-fover-group)#exit
hostname(config)#context context_name
hostname(config-context)#join-failover-group {1 | 2}
hostname(config-context)#exit
You can share the configuration if this step is already done.

WLC 2125 - Lab setup

Good Afternoon,
I'm trying to setup a WLC lab here at work and I'm having a few issues. I'm trying to plug an AP directly into the WLC and I'm having issues with the AP getting an IP using the Internal DHCP server option.
Is this setup not going to work without a switch involved? Unfortunately, I don't have a switch available for use, but I'm trying to find anyway to setup this controller to have DHCP that can serve my AP an IP address to join the controller.
Any advice or help will be grateful. I can also provide my management and ap-manager information if needed. Also, I do have DHCP proxy enabled.
Matt Cooper

Hi.
the internal DHCP server is for clients. it can provide IPs to clients that connect over wireless. It does not provide IPs to anything on the wired side. So, its not going to work with your situation.
If you can't set up a switch and configure it with a DHCP pool to serve the APs what you can do is to configure a static ip on the AP.
check here: http://goo.gl/tEOdAa
Note: in the commands in the above link, if the keyord "lwapp" didn't work with you you try using the keyword "capwap". (using of either keywords depends on your AP model).

Condenser mic for voice recording - setup advice ??

Hi All,
Newbie to GB. Want to setup my condenser mic (3.5mm) to record voice tracks. The condenser mic was purchased with a HD Camcorder and works great for video. Currently the mic works through the "line-in" but at very low level. Done a little research and Hangtime recommends the use of a USB interface.
http://www.thehangtime.com/gb/gbfaq2.html#recordlinein
(thanks hangtime).
I'm now looking at the griffin imic as an inexpensive solution. Before I drop my $$ on this guy, is this the best solution. (or will it do the job right??)
Feedback appreciated.
Matt.
G5 D1.8 1GB/160/SD Mac OS X (10.3.9) Garageband 1.1.0

My advice would be the same as CD's. If you have a Line-In, for the same price as an iMic you could get a small mixer like the Behringer UB502 Eurorack Mixer for about $38, add a 1/8" to 1/4" adaptor, and you'll have much better control than with the iMic alone.
