Firewall port TCP /UDP 1

What type of WAN are you running between sites?

administration for network connectivity for avaya communication manager page 210 only mentioned tcp 21873 for pre cm3.o and tcp 21874 for above cm3.0....don't see any udp port required.....

we got just a "normal" wan between this two locations
The s8300 & the s8700 both are running on the sw 3.1.2
i also found the tcp port 21874 on the avaya ip telephony deployment guide on page 447 and then they write "beetwen s8x00 and the g700 TCP any "!!
and obviously my customer want a specific range.
and nowbody can tell me witch port must be opened on the firewall that both system are running well

I got this from our BP when I asked about QOS and ports

"The traffic that I would expect to be seen in the .... Company configuration would be the actual bearer traffic between the different locations, if we were to look at a "sniff" we would see traffic between the different VOIP resources of the G700s(you can see these IPs by doing a "show interface" within each MGP), as well as, the IP addresses of the Medpros("list node-name) at the main location using UDP port ranges translated on the network region screens."

Look at the ip-network-region screens for UDP port ranges.

"I would also expect to see the signaling traffic(H.248) between the CLANs at the main and the MGPs at the remote locations, I would expect to see this traffic on either TCP port 2945 or 1039 depending on whether or not the link is encrypted."

I think the 2945 is un-encrypted.

"And finally we would expect to see the data that makes up the filesync(.xln pushed from the main to each LSP), on R12(2.x) this traffic occurs on TCP port 21873. The filesync traffic would only be seen if an administrator completed a "save trans lsp" within ACM or every morning when the server runs maintenance.

We are running R12 (2.1) so the way he worded the above statement may mean that the port changes in CM3.
