Absolute minimum configured to make internal calls using CME

Trying to understand how the different hardware (dsp/aim/pvdm etc components) and software configured components work together.

This is a stand alone lab, not connected to anything else. One 2811 CME router, One 3550 POE switch, and 2 7940G phones.

So, what I've done so far is configured a 2811 with Call Manager Express 4.3.0.0 (I want to try different versions to see their differents as I go through this). It's got the tftp files for the phones loaded .

tftp-server flash:/phone/7940-7960/P00308000500.bin alias P00308000500.bin
tftp-server flash:/phone/7940-7960/P00308000500.loads alias P00308000500.loads
tftp-server flash:/phone/7940-7960/P00308000500.sb2 alias P00308000500.sb2
tftp-server flash:/phone/7940-7960/P00308000500.sbn alias P00308000500.sbn

Telephony services is running, using IOS 12.4(24) T8.. I have the 2811 trunked to a 3550poe switch, where I have configured voice and data vlans and a trunk port.

I have connected two 7940g phones to the 3550 switch, and they power up and get their ip addresses.

#sh ephone on the cme router shows the following

What am I missing in order to get the INTERNAL calls working just between these two phones?

Thanks much!

What happens when you dial the opposing DN from a phone? Anything? Can you ping the phones from the router? I would suspect the switch port connected to the router is trunked? It would seem so due to the ephones showing registered. I am weak on CME, but those are my initial thoughts.

DHCP is running, phones get their ip addresses.

Nothing happens, there is no dial tone and no ringing the other phone.

Switch port is trunked from the switch to the CME router.

Phones are pingable from the cme router.

Try assigning ephone1 to ephone-dn1 and 2 to 2, let us know what happens. Maybe the two need linked, right now they are two separate entities.

Instead of speed dials use button

bobfromfpl - When trying to dial 1000 or 2000 on either phone, there is no sound or any indication of dialing, and then phone flashes "AutoDial Cancelled" on it's screen.

Rebooted router and phones as well, no difference.

Try this.

wgroom - Once I enter "ephone 1" or "ephone 2" from the (config-ephone-dn) mode, it goes into the (config-ephone) mode where "label" and "name" commands aren't recognized.

The label and name commands work under the (config-ephone-dn) mode though.

Let's remove the speed dial configuration from this completely, how should it work for direct dialing each phone?

JeanM

In CME GUI, under Configure - Phones, i see the following

0014F243EC46 shows phone sequence number 2, does not show any primary line number and caller ID
0014F243EF4B shows phone sequence number 1, does not show any primary line number and caller ID

In CME GUI, under Configure - Extensions, i see the following

Telephone number 1000, has Sequence Number 1, and no Caller ID/Name, Type = Normal
Telephone number 2000, has Sequence Number 2, and no Caller ID/Name, Type = Normal

Dialing 1000 or 2000 or any other numbers, on either phone acts like it's trying to dial for a second, no errors, then flashes a "AutoDial Cancelled" ?

JeanM

Well, made some more progress

I am now getting dial tone, and I can actually hear it dialing etc. My specific issue had to do with routing!

JeanM

Alright, it's now working both directions

How do you configure Call History to show for let's say 24 hours? It seems to not keep previous call records and I can't find a command that controls for how long these show etc?

CDR's are pretty odd in CME. You can setup a free syslog server and have them send the CDR's to a external server.

JeanM

Odd as in no configuration changes can be made? I guess I'll spin up a VM with a free syslog / splunk if there is no other way.

Sweet! I'll do that tonight!

Congratulations on getting dial tone and two way calling! Maybe I did not see it, or if I did do not understand completely, but what step allowed dial tone to come across?

Jollycork

Appears to be assigning the ehone line to a button I think the 7940s have 4 buttons for 4 line.

JeanM

wgroom - what call manager do you use, like?

I'll break it and confirm when I have time.

bobfromfpl

Using the button command associated the ephone-dn to that line button, whereas previously you had only speed dial 1 configured. When the phones were registered they didn't have a line number assigned. This happens more often than I'd like in my work environment when junior admins delete a directory number versus disassociating it from a device.

pitviper

yup, you won't get dial-tone without a DN assigned to a button.

wgroom

JeanM, I use Unified Call Manager 8.6.1 and Nortel Options 11, 61C, and 81C for a large hospital system. Over 7K phones all told. No experience with CUCME, but as soon as my 2821 arrives I will load CME and get started. This intrigued me, thank you for sharing.

Last night, I kept changing one variable at a time to see what it does.

I have it mostly down, other than the button X:X configuration. It seems that if both phones have button 1:1 then the buttons on two phones somehow get linked, even though they are different devices ? For example, hitting the button on one phone, changes the icon on another. So, currently I have it as Button 1:1 for one phone and button 1:2 on another .

I'll need to read up on this to clearly understand this.

pitviper

"button 1:1" means:

[Physical phone button number]:[DN number]

So if both phones are assigned DN 1 [button 1:1] they are essentially sharing a line.

and if you want to get real crazy, you can use alternate button separators (":") and overlays too
