Cisco Unified IP Phone 7965G and 7945G Phone Guide for Cisco Unified Communications Manager 6.1 (SCCP and SIP) Using Cisco Extension Mobility 47.

I am trying to configure a Win2k3 server as a DHCP server for my Cisco 7945G IP Phones. The phones are in VLAN 20 and the PCs are in VLAN 10.

I have two DHCP scopes built on the server. All PCs, even the ones plugged into IP phones, are able to pull IPs fine. The phones are not pulling IPs though. The phones are stuck on 'Configuring IP'. When I do a packet sniff I can see the 'DHCP Discover' message from the phone, and the subsequent DHCP Offer message from DHCP server (via router proxy). The DHCP offer message has the client IP and the phone mac address.

So the phone looks like it should get the right address but it just keeps sending DHCP Discover messages from IP 0.0.0.0 as if it doesn't see the Offer messages. Here is the IP port config on the switch (cat 3550): interface FastEthernet0/24 switchport access vlan 10 switchport mode dynamic desirable switchport voice vlan 20 spanning-tree portfast Here's the port on the cat3550 that is uplinked to the 2811: interface FastEthernet0/1 switchport access vlan 20 switchport trunk encapsulation dot1q switchport trunk native vlan 10 switchport trunk allowed vlan 10,20 switchport mode trunk switchport voice vlan 20 Config on the 2811: interface FastEthernet0/0.10 encapsulation dot1Q 10 native ip address 192.168.10.1 255.255.255.0!

Kenboonejr: Here's the port connected to the DHCP server. Again, I can see the DHCP Offer messages being sent to the phone with the correct config (voice VLAN IP, Phone's MAC Address). It's almost as if the phone doesn't see the Offer messages at all but they are there. I configured the phone with static settings and it registered no problem, got dial-tone, etc. I was able to ping it from everywhere (DHCP server, CUCM server, PC on DATA VLAN). We're set to access mode administratively now.

Kenboonejr: Yes, it was on VLAN 20. Yes, I can see the phones.

I'll let you know if that makes a difference. Patching the Winserver didn't. Yes on the factory reset.

The settings on the phone show that DHCP is enabled but it is not pulling any info. Which of course it won't because there are no DHCPREQUEST or DHCPACK messages following the DHCPOFFER. The handshake is not successful and thus won't have any IP settings configured. Generic Pcmcia Memory Card Driver Windows 7. Just to recap: We know that the DHCP server is seeing the IP phone and there is connectivity since the server is responding to the DHCPDISCOVER messages with DHCPOFFER messages. We also know that the port on the switch is configured correctly whether we're on the VOICE or DATA VLAN because the server provided IP addresses in the DHCPOFFER messages are always from the correct scope. In other words, when the phone boots in the VOICE VLAN the DHCP server recognizes this and offers 192.168.20.x IPs. When the phone boots in the DATA VLAN the DHCP server recognizes this and offers 192.168.10.x IPs.
