Integration of IP telephony

Akaffou Aristide Akaffou — Sun, 17 Mar 2019 11:37:40 GMT

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.

Regards,

All you need to make sure is

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

Akaffou Aristide Akaffou — Tue, 20 Oct 2015 13:57:17 GMT

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.

Aristide

That's a whole different

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

If you need assistance on

Jaime Valencia — Tue, 20 Oct 2015 16:02:35 GMT

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

thank you Jaime.

thank you Jaime.

Hi Jaime,I have a question to

Akaffou Aristide Akaffou — Tue, 20 Oct 2015 23:41:33 GMT

Hi Jaime,

I have a question to ask. Does phone must be in factory default to perform new installation?

For me it is not really a new installation, I initiate a migration to CME from CUCM.

I am sure this a issue because the router tell me that there is a dhcp conflict.

Now we have full connectivity between data and voice network.

Its really not needed to

Nadeem Ahmed — Tue, 20 Oct 2015 23:56:41 GMT

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

Thanks Nadeem,I have no

Akaffou Aristide Akaffou — Wed, 21 Oct 2015 09:23:16 GMT

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.

Best Regards,

Hi Aristide,If the phones are

Rajan — Wed, 21 Oct 2015 10:32:26 GMT

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.

HTH,

Rajan
