Call Manager behind the PIX Firewall 525

[ciscomoon]

I have assigned IP Address to call manager which is 192.168.2.200 i have registered two cisco 7940 in call manager. I can make calls with in the same network.

Now i would like to make call from diffrent subnet.

Basically location 1 has got call manager and its IP is internal IP which is 192.168.2.200.

From location2 i want to register another ip phone into call manager but the location 2 ip address is on diffrent subnet 10.1.1.1.

In this scenerio i cannot use tftp server as you know the tftp of call manager is internal IP which is 192.168.2.200.

In this scenario how do i registered the cisco 7940 Ip phone from location 2 which is in diffrent subnet 10.1.1.1.

Any suggestions.

Thanks

You can add some static routes to route the tftp traffic to the callmanager subnet.

Thanks for your reply. Do you know what are the commands to add the static routes to route the tftp traffic to the call manager.

Thanks

If you want IP Phones from outside to register with ccm, you need to enable

fixup protocol skinny 2000

on PIX.
