Hi,
I am in trouble with a routing in a network.
I have a firewall which is in charge of a routing in a network. I want to integrete ip telephony with a CCME.
Does I need to configure router on a stick in my CCME router or I have to configure two separately interface and let the firewall makes the routing.

Its really not needed to perform factory default to each phone. you can erase the CTL & ITL while registering phone to CME .

All you need to make sure is that the endpoints can reach each other directly, and that the endpoints and CME can reach each other.

ok, we can ping each other but the problem it is the phone registration.
Is there a particular configuration that I have missed?
ip dhcp pool voice
network 10.19.51.0 255.255.255.0
default-router 10.19.51.1: IP @ of a firewall which make routing
option 150 ip 158.113.41.84: IP address of the CUCM router
dns-server 158.113.41.123
lease 0 7
The main problem is phone registration, because the server can ping IP phones and IP phones won't register. I don't know why because all services is activated in a CUCM?
The CCME is a dhcp server for the ip phones.

That's a whole different thing you're talking about there, you never mentioned CUCM in your original post.
But, it's still basically the same thing, you simply need to make sure that you have the same routing I mentioned, endpoint to endpoint, and endpoint to CUCM, make sure you're letting the required traffic in your network.
Look at CUCM traces, if you don't see the registration attempts, you need to fix your routing.

Sorry,
ok How can I fix my routing? I have to delete router on a stick in my router ?

If you need assistance on general routing/switching, you want to post in the CSC area for that. I can't tell you how to fix your routing/switching, I would assume you know how your configuration looks like, and how your routing is configured right now to achieve that, if not, then as previously suggested, post in the routing/switching area of CSC

Thanks Nadeem,
I have no access with phone settings they required a password and I don't know it.
The phones have already registered in CME and I want to migrate to CUCM.

Hi Aristide,
If the phones are currently registered in CME, then you could pull out the configuration file for that particular MAC which is available in flash using TFTP or open the config file using "more flash:<filename>" command:
sh flash
open this configuration file in any text editor and search for the keyword password to find out the current password set.
