Configuring CM List

12 posts in this topic

I have been having some problems with my ip phone registering the ip address. I used a static ip address on the phone and now it is humg up COnfiguring a CM list. I am trying to move forward in my certification for CCVP but this part is difficult. I was able to configre my router a 2811 for pots to call over the PSTN, which took some work. I thought the IP phone would be less difficult. I have used almost every configuration I could find to get it too work. Any help would be great.

 

dial-peer voice 5 voip

session protocol sipv2

session target ipv4:192.168.1.1

I would even take a basic configuration. I am trying to use my 7940 to call my cell phone. I was able to complete this task using my POTS phone. What am I confiring wrong?

Let's start very simple and I'll check your config and maybe offer a little advice along the way.

 

1. You say the phone is having trouble registering?

 

We need to get the phone to the CME first don't you agree?

 

What does your DHCP config look like?

 

Can you get an IP Address for your PC for example first? Then for the phone - does it get the IP? Does it load the config from the CME? What is its TFTP Server?

 

Do you have the correct IP Phone images loaded and advertised for download?

 

Are they not fine and not corrupt?

 

Do you have the option 150 setup correctly?

 

Can 2 phones talk from the same CME?

 

Where's the rest of the 2811 config?

I'm concerned a bit. You say you've been using configs you found versus created.

 

That's great. Now why are you studying for the CCVP again? I'd hope to become the expert.

 

So...

 

Let's work on understanding the process and then we'll talk configs - ok?

 

If your analog phone works great, we need to get the IP Phone registered before it can make those outside calls - agreed?

Static IP Address - Sounds great...

 

And then...

 

Then you still need to configure a TFTP Server to download the image.

 

Then you still need to get the list of CMs... from somewhere... how does the phone know this by itself?

 

I like DHCP myself...

 

But you want static so... there's more you owe the phone if you want to talk.

You need a TFTP server setting. The TFTP setting is what is used to pull the CM list from the CME. You also need to either assign a button to the ephone or allow auto assign under the telephony settings.

Disable DHCP and DNS to Test a Phone

Your phone can display one of these messages:

 

DNS Error or Configuring IP

 

Opening <IP address of Call Manager>

 

Configuring CM List

 

You can easily determine if you have a faulty phone or a faulty configuration. Reset the phone to the factory default configuration, and then hard code all the necessary IP parameters into the phone. This eliminates the possibility of DHCP and DNS issues.

 

 

 

Sounds like you got...

Step 4:

CME_Voice (config-telephony) # create cnf-files

CNF file creation is Already On

Updating CNF files

Verification:

 

Verify you can reach this ip from the subnet where the statically assigned phone is at:

 

ip source-address 192.168.1.1 port 2000

That should do it.

 

You need to do the same step for your phones.

 

Static config ought to be easier than DHCP technically...

 

But the files have to be there and I think we nailed it.

 

Try and see please.

I did not set the option 150. Can I use an IP phone without a TFTP server? The CBT nugget does give much information for VOIP but POTS was easy to configure. I am using a static IP. The phone is not registering with the DHCP server, which is run by my Windows Server 2008. What I am thinkink is the phone is not using the 2008 Server DHCP server. I can ping the network from the switch. I sed the POTS phones to talk through the CME so I know it works over the internet.

 

Do you have the correct IP Phone images loaded and advertised for download?

 

Now do I need the same image on the TFTP server that is on the phone. SCCP is on the IP phone. The rest of the configuration really does not apply NAT and everything else is working fine. ITs the telephony service and dial peers that I am trying to configure.

The only way to become a CCVP is to study. Before I move on to CIPT 1 I want to m ake sure I got the basics down. I am not a dumper so I take my studying serious.

Yes that is what is troubling me, Jeremy makes it seem so simple but the 7940 phone is giving me a headache. If i do not use a static IP address it hangs and configuring an IP address. MY thought is that the phone is not accessing my DNS server.

 

Should the source IP address be the DHCP server or the default router?

Question

 

1. What is the purpose of the TFTP server if the router is creating the CNF files. Is the a show command to check the CNF files?

 

I know I do not have the TFTP server setup, I do not have the software for the IP phone to register with the TFTP server. In the CBT nuggets CVOICE all Jeremey did was creat a dial peer and point it to an IP address. From what I have read, it seems that he must have done a lot more in the background to make the call. It could be that he was just using two routers with a serial cable which is easy to configure.

 

I am using:

Version 7.0(1)

Cisco Unified Communications Manager Express

 

Thanks Darby you seem to be like me jack of al trades with no limits to learning.

Ok the TFTP server is downloading the CNF files from the router that makes since. When you say I need to get the CM list from somewhere, exactly what do you mean. I have gotten the phone to take the static IP address, where do I get this CM list.
