Ports that need to be open on PIX for Unity and CME

[ubergeek1]

Hi all,

I have CME in our subnet, 192.168.10.x and a remote Unity box is in 192.168.1.x. I can connect to it but I dont hear any audio (the Unity welcome message). Voicemail works on our local subnet on our CME and the phones register in our local subnet, the only issue is Unity on the remote subnet.  I added access lists like these:

access-list permit-in permit tcp 192.168.1.0 255.255.255.0 192.168.10. 255.255.255.0

access-list permit-in permit ip 192.168.1.0 255.255.255.0 192.168.10. 255.255.255.0

access-list permit-in permit udp 192.168.1.0 255.255.255.0 192.168.10. 255.255.255.0

However no luck. 

What ports need to be open from one subnet to another with a PIX in between. I dont have the PIX config right now, but it is plain vanilla, nothing complicated.

Thanks all

Hi Ubergreek

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/port/8_0_2/portlist802.html

this is generalised list of tcp udp ports for CUCM, might be helpful. let me have a look around if there is a dedicated guide for cme//

try this for cme
