No voice when pickup phone(Both end)

[ciscomoon]

Hi i have just installed ccm 4.1.2. I successfully registered 3 ip phones
=======================================
Tftp sever is pulling all three files from ip phones and getting registered in ccm. All the phones in ccm is registered and showing ip addresses of each phone. Given below more details:
=======================================
1. Call manager Ip Address: 192.168.2.150- Location Florida- Using Pix 520-Public Ip port forwarding to ccm(port 69 and 2000)
2. 7940 ip address 10.1.1.30 Location miami - No VPN Tunnel and PIX
3. 7940 ip address 192.168.0.50-Location Chicago - No VPN Tunnel and PIX
4. 30 Vip ip address 192.168.1.30 Location arizona - No VPN Tunnel and PIX

Above three phones are in different location as you can see above subnet.

=> From 1 i can call 2 and 3 and vice versa. All 3 phones can receive and make calls but no voice.

=========================================================
Please note i am not using gateway.

Here is my simple setup:
Call manager ip address is 192.168.2.150. Public Ip (209.64.121.xxx) is port forwarding to 192.168.2.150 which is call manager.

I have three phones on different locations which is registered in call manager. I am using tftp server as a public Ip (209.64.121.xxx)this Public ip port forwarding to my call manager and succefully registering all the above three phones in ccm.

Call manager is behind PIX firewall and my pix config is:

Please advise.

Voice traffic goes from IP Phone to IP Phone. It sounds like you are allowing the signaling traffic to get to the CCM server but the phones can't get directly to each other. Once the call is established the phones must have direct communication to each other or no voice will go in between them.

Thanks for replying pndscm

Is there any solution to my query

Thanks

 

[pndscm]

We would need more information about the network. How does Miami, Chicago and Arizona communicate with each other? You say there is no VPN or PIX.

 

[ciscomoon]

Thanks for replying. Miami, Chicago and Arizona phones are registering in the ccm.

CCM is assigning extension number to Miami, Chicago and Arizona.

This setup is like for example.

I am travelling and i like to speak to my family or employee i carry my IPphone with me and plugin to the any network . The ip phone registered in to call manager through tftp and i can dial extension to speak with family or employee.

I hope its clear Miami, Chicago and Arizona communicate each other via call manager.

The problem is more than likely a routing issue. I'm not a PIX expert but it looks like you are allowing incoming traffic on the voice UDP ports to get to CallManager but not anywhere else. To pass voice between phones, the PHONES must be able to get to each other directly, not through the CallManager. The CallManager is providing the signaling traffic correctly but voice packets do not go to the CallManager. They go directly between the 2 phones once CallManager has set up the signaling handshake. A simple PING test from subnet to subnet should go a long way to identifying the problem.
