7940 IP Phone "Configuring CM List" while registring with CUCM 8.6
I'm new to this forum & also newbie at CCNA Voice so please bare with me.
I have three 7940 ip phones. One phone has 8.1(2.0) firmware version. Second phone has 8.1(SR.2) firmware version.
CUCM version 8.6 running on Vmare Exi 5.5.0
Cisco 2821 router and 3750G switch.
I'm trying to register my phones with CUCM. Three sub-interfaces on router have been configured on Gig0/0 for data, voice, & server vlan respectively. Also ip-helper address given at voice sub-interface (ip address of my cucm)
Dhcp server - I created my cucm as my dhcp server. For dhcp subet configuration please see attached file.
Phone with 8.1(2.0) firmware the screen is stuck at "configuring ip" and the phone with 8.1(SR.2) is stuck at "configuring CM List"
Nothing happens after that..I have rebooted the phones to factory default & still the same result.
Please kindly help me with this problem
Guide me with the process if I'm missing something important.
