CME to CUCM

sendalot

Currently have this setting on CME.


ephone-dn 1
number 1000


ephone-dn 11 dual-line

number 1001

name Snd Lt


ephone 1
mac-address 0014.A998.D06D
type 7960
button 1:11


ephone 2
mac-address 000B.5FF9.306B
type 7960
button 1:11



After getting some job done in CME, I'd like to move over to CUCM.


(1) Is it possible to have one phone get settings from CME and have the other phone get settings from CUCM? By playing around with MAC address?

(2) Does CUCM respond to option 150 requests from the IP phones to give them settings? Does CME from the router have to be disabled for this?


Thanks.

You could possibly setup 2 different DHCP pools and have the phones in different subnets and VLANS.

What if I want to completely transfer over to CUCM? Do I wipe CME settings and just set the CME router as a voice gateway?

shodown

yes thats what you have to do. You can also shut down the telephony service so you can keep some of the config there. Just potion the TFTP to the CUCM.

I have no tftp clause.

I have this, do I just change the ip address below to that of CUCM?

Where is your DHCP server?

Telephone service is going to get shutdown because the router is no longer the call processing node.

You should have something like


IP dhcp pool Phones
network 192.168.100.0 255.255.255.0
default router 192.169.100.1
option 150 ip 192.168.101.1 (this is your CUCM IP)

sendalot

oh I see. option 150 is the deciding factor.

ip dhcp pool VOICE_SCOPE
network 10.10.20.0 255.255.255.0
default-router 10.10.20.10
option 150 ip 10.10.20.10
dns-server 8.8.8.8


So if CME is 10.10.20.10 and CUCM is 10.10.10.20

I just change it to option 150 10.10.10.20?

Thanks

shodown

That is correct

sendalot

Also, trying to confirm the setting I read up.

After changing option 150(tftp) to point to CUCM VM instead of CME router, do I in CUCM, go to Device -> Gateway and put the CME router as a SCCP 2911 gateway?

CUCM will then use the CME router to process voice data?
Thanks.
