PCM routing issue//HELP!!!

[southeasternMI]

Issue with PCM connecting to VM server, funny because you can web to the director from the client desktop and ping the VM server fron the client, but the PCM has the RED X at the bottom, uninstalled and reinstalled nothing. The rout to the voice side is thru a pix firewall which is has address NAT to the VM server IP address. You would think that if you can install the PCM and web to the server then we're good.

Run the Tapitest thingamajig. Sorry, I don't have the instructions handy. Maybe windows firewall? Is it only one computer?

[southeasternMI]

Nope its all clients, you mean the ctrl - F12 to get to the PCM log. What service does Tapi use, maybe there is a policy in the firewall that is preventing Tapi or CSIS from connecting to the server?

Ports

I think the call manager uses tcp port 5440

you may very well not have that port open

What version? Host site or DVM? I have a ticket open with TAC that has similar symptoms but is only effecting my DVM. Issue is with 12.14.4002.

Are you using a proxy server (like ISA)?

Client/Server Internet Services

CSIS is a ShoreTel proprietary protocol that uses HTTP messages to communicate
between client PCs and Shoreware servers. The CSIS protocol communicates
configuration updates such as call handling mode settings and Outlook integration.
The CSIS client holds open a pending HTTP request in order to receive notifications
from the CSIS server. Network devices, such as firewalls and proxies, must not

automatically close these pending requests.

I once spent a day wondering why PCM wouldn't work. The problem was that PCM was trying to send its requests to the HQ sever (through the VPN) via the web proxy. Once the client added the HQ servers IP address as an exception it was all good.

PCM gets its proxy settings from IE.

Opps, sorry

Well there are 3 networks (all different subnets)one is a state network and the other two are voice/data of private company. The state network is connected to the other two thru a firewall, but doesn't have to travel, because the other two subnets are in the same building. That location has a DVM, but the clients on the state network use the route in the firewall to connect to the Main VM server (No Proxy). The route from state network to voice network has to be good, because we can web to and ping the VM server.
