Configuring CME router

Guys, could you help me with configuring 2811 router as CME and TFTP. To be precise:
1. The list of required software.
2. The list of required hardware (at least for small business).
3. How to upload IP phones frimware and CME software.

Probably the list above is not full, but this is what i'd like to know at the moment.

Thanks in advance.

I believe a 2811 can only support ~32 phones. You will be able to create up to 36 ephones but only 32 will be supported.Also, you will need to upload the firmware of the phone on the flash. You don't need any CME software, just to configure the telephony-services.

You need to download the CME device pack. Also if this is for a live business make sure you don't forget voicemail.

Guys I'm a bit confused in terms of CME software. Should I install Cisco Unified CME 4/7/8/9 or not?
And how to create /phone/7940-7960 directory?

shodown, could you clarify what doesCME device pack mean please.

I believe device pack is the package with the files that need to be loaded into flash for CME if they aren't preloaded on the router, and you don't need to configure CME itself, but configure phone system settings (so CME as a service is not "configured" but loaded into flash like an IOS).

Ideally you'd want CME 8 or 9, but I practiced on 4.x and was fine.

The device pak loads all the files onto the flash of the router. Most of them you don't need, but you never know. It has firmware, MOH, ACD files, things of that nature.

The Device pack is all of the phone loads, GUI files, MOH that pertain to a certain CME version.

You listed having a 2811 so ver 9.0 is not compatible. It really depends on what you have access too and the IOS thats running on the router. The newer the better. For the 2811 8.6 is the best bet but of course you need IOS 15.1 (4). With 15.1 its additional configurations that need to made before you can receive calls. With 12.4 you could run version 7.1.

To make a directory mkdir flash:/phone

If you have the device pack you can extract it to flash
archive tar /xtract tftp://tftp-server-ip-address/cme-full-8.5.0.0.tar flash:

It will create all of the directories and subdirectory but make sure you have a flash card thats big enough.

If your flash card is smaller you could just upload the tar file for the phone load you need you can extract it to flash:/phone directory. The tar file will create a subdirectory in the Phone directory. You can also upload each file individually onto the router which will take quite some time. For sanity sake you should create a subdirectory in the phone directory and upload the files for the specific phone into that directory.

mkdir flash:/phone/7940-7960

For configuring CME the link shodown provided gives you everything you need to set it up.

Read the pdf file shodown shared, step #5

Guys, will this scheme with TFTP and IP phones in different IP subnets work?

ip dhcp excluded-address 172.16.1.1 172.16.1.10

The thing is that IP phones receive TCP/IP config successfully, but can't find TFTP server.

And could you also expain why this command isn't working:

CME_RTR (config)#tftp-server flash:/phone/7940-7960/P00308010200.bin alias P00308010200.bin

416604160 bytes available (95510528 bytes used)

And finally, is it mandatory to install cme-full-7.1.0.1.tar?

Your phones may not pick up the firmware if you do not actually have the file structure flash:/phone/7940-7960/ and have the specified files within the folder.

The other issue that could exist is that there is a typo in the tftp-server command and it does not match the exact spelling or characters of the file name within the flash.

Have a look at those and see how you go.

Finally managed to start up two phones. The problem was related to ip phones firmware.

Guys, is it mandatory to configure DHCP parameters for data traffic or workstations? The things is that I'm going to use DHCP server on Windows OS, and, thereby don't need this service on the router.

I wouldn't have thought so. Just get rid of the data pool and set the ip helper-address on the connecting interface to the Windows machine.

Oh, I've totally forgotten to say that Windows DHCP server is in the same subnet as workstations so there is no need to configure ip helper-address, is there?

Oh right yeah got you! Yeah I think it works. I'm at work so cant properly test but according to packet tracer you can do it! you can plug the server into one of the switch ports with the data vlan configured I think.

Guys I've tried the scheme with Windows DHCP server for data VLAN but VoIP doesn't work. Below are my sh run outputs from L3 switch and CME router (some line were omitted for brevity).

All workstations receive IP from Windows DHCP server successfully. However, IP phones don't receive IP from DHCP configured on CME router.

Any thoughts what can be the reason of the problem?

From your output, your phones are not connected to the correct Voice VLAN. They are sitting on your Data VLAN and therefore will no get back to the CME. Your Phones are connected to 3/0/11 and 12... your switchports are configured for the Voice vlan on 3/0/13. Ports 3/0/11 and 12 are only in your data vlan.

cisco_nerd, yep, that's my inattentiveness.

Should I configure something else for Music on Hold to work? For now it doesn't work.

Guys, what device (and what modules) can play a role of PBX?

Guys, I totally forgot what these files are aimed for.

P00308010200.bin
P00308010200.loads
P00308010200.sb2
P00308010200.sbn

Could you remind me that please.

Looks like it's firmware for 7940/7960 :

Cisco Unified IP Phone 7940/7960 SCCP Firmware Load 8.1(2)

Guys, is it possible in CME to change standard tone (beep beep beep) for some melody in the same way it is realized at mobile operators?

Guys, below is my diagram:

On the left side (Moscow) the IP phones 1001, 1002, 1003 and analogue phones 2001 and 2002
On the right side (Saint Petersburg) the IP phones 7001, 7002, 7003

Calls between the IP phones in Moscow and St Petersburg work fine. Calls between the IP phones and the analogue phones in Moscow also work fine.

The problem is that calls between the analogue phones in Moscow and the IP phones in St Petersburg don't work.

I tried to specify the numbers of analogue phones explicitly in destination-pattern but it didn't help.

Please, have a look to solve this issue.

What does the debug show, no dial peer found ?
Do you get fast busy?

I had similar issue, but not the same I don't think, that was resolved in my case after adding pots dial peer (vs. voip)

It was a codec mismatch between IP phones and analog phones 729 vs 711.

Guys, please help to configure CIPC in CME. I entered:

ephone-dn 4
number 1004

ephone 4
device-security-mode none
mac-address BCAE.C551.F639 <- MAC address of my laptop with CIPC
type CIPC
button 1:4

The laptop is connected to the network but CIPC doesn't work.

This is what I can see in Status Messages on CIPC:

TFTP Timeout
No Trust List Installed
No IPv4 TFTP Server

Which VLAN should a laptop with CIPC belong to? Voice VLAN or Data VLAN?

Guys, besides the question above I also have one regarding ringtone. I've copied .raw file in flash:/ringtones folder and specified it in RingList.xml file which is also in flash:/ringtones. The ringtone isn't working. Should ringtones and RingList.xml be located in flash: but not in flash:/ringtones?

A laptop with CIPC should belong to data vlan. Make sure you can ping your tftp server from the laptop with CIPC.

The laptop is belonged to Data VLAN now but CIPC can't find TFTP and Preferences->Network on CIPC is not active (unavailable) for configuring.
