Please help guide me through a new CME install

2) 2nd generation four port FXO

3) 20GB IDE Disc Daughter Card on Slot 1

4) High Density Voice Module - 8FXS/DID on Slot 2

5) 256 MB Compact Flash Card

So far the steps I have taken are:

1) installed: c2800nm-advipservicesk9-mz.124-20.T.bin

2) ftp'd into flash: cme-full-

3) archive tar /xtract tftp:// flash:

4) Ran the (config)#telephony-service setup command

5) Installed a 3560 switch with POE

6) Connected gi 0/0 of router to fa 0/48 of switch.Configured both sides for 100mb /full

7) Configured switch data and voice vlans on switch and router gi 0/0 sub int's

8) Created trunk (encap dot1q), allowed both data and voice vlans, verified trunk is up and vlans are allowed. Verified switch can see router with sho cdp nei detail

9) Configured switch ports for IP Phones;

switchport access vlan 100 (data vlan)

switchport voice vlan 666

switchport mode access

10) Connected my 7940G IP Phone to an access port

11) Unlocked the Phone with **#

12) Reset phone to factory settings

Manual IP config on phone or to configure DHCP.

Configuring IP means the phone is looking for a DHCP as it's the default

I'm assuming the phone is already configured or auto-registration is enabled.

Re: Please help guide me through a new CME install


Java is right, it sounds as though you need to set up a DHCP scope for the phones. Have you done this?

example below, hopefully it might help:

ip dhcp pool *the name you want to call the scope**

network x.x.x.x x.x.x.x

default-router x.x.x.x

option 150 ip x.x.x.x

You may also need to exclude some addresses:

ip dhcp excluded-address x.x.x.x x.x.x.x

ip dhcp excluded-address x.x.x.x x.x.x.x

**substitute with your own IP ranges**

Re: Please help guide me through a new CME install

Hey guys,

Thanks for the feedback, however I do have the ip dhcp pool configured that way.

The phone is also set to ip dhcp enabled, it see's the correct vlan that it's suppose to be in and I have even tried a config erase on the phone.

What else could cause the phone to hang in "configuring ip" ?
