Here is my simple setup using only CCM and Ip phones no other devices is configure or registered in CMM except IP phones 7940 and would like to do the testing with ccm alocated extensions:
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.
Sounds like all the phones can see the Call Manager ok but can't see each other.
Call Manager is setting up the calls but then steps out the way when the converstaion begins and the phones talk directly to eachother. I would therefore guess the problem ia a routing issue. Have you checked all the routing between phone subnets?
Since all the phones in different location. Hence unable to ping each other and as you you its impossible to ping from one location inside interface to another location inside interface unless we using vpn tunnel between all locations.
Phones are registering and working fine with in the same network. I already did the testing.
The phones need to be on a well-connected network. You will have to design the network to allow every phone to reach every other phone. As it was stated earlier, Call Manager only handles the call signalling. Each phone must be able to contact the Call Manager to register, make calls, etc. Once a call is made and connected, the Call Manager notifies each phone with the address to send the RTP (voice) stream.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
