Setting up new voicemail with unified messaging

There's quite a lengthy walk-through of how to set this up with Exchange 2010 and Unified Messaging:

And, here's a TechNet article that explains how to whitelist an IP address with Exchange 2010:

Check which ports you ave exchanged configured on for inbound SMTP traffic as well as make sure you allow the phone system relay rights.

443 is a web related interface.
SMTP commonly uses, 25, 465 SSL, 587
Your issue might be the setting require authentication.  In this case on the toshiba config, include a toshiba service account you create in your AD to use when authenticating with exchange server prior to transmitting tge message with the voucemessage attached.

On the exchange server run netstat -an | find /I "listen"

One of these ports is exchange listening got incoming connection, check the external firewall to see how and to what port you direct SMTP traffic from the outside.

I have an account vmail@mycompany.com already and Toshiba is asking for port 465

465 is an encrypted port, why is it asking?
Do you have your exchange configured with one Secure SMTP port (SSL required to connect)?

When configuring the outgoing email, do you have an option to specify another port other than 465 if 25 is unavailable, see if you can configure your exchange to listen with SSL certificate on port 465, or if toshiba can be directed to port 587, configure an inbound SMTP connector on the exchange on 587 similar to the port 25 no ssl required to connect.

Ok Toshiba support is asking to allow the IP of the voicemail 192.168.1.8 using any port we want except for port 443. Where do I do this in Advance Firewall?
would this be an outbound rule or both?
I'm lost here

I do not understand what they are asking you to do.  Authorize access from the Toshiba Voicemail to what destination? To external sources that will be on your external firewall.  Access to LAN devices would be on inter-vlan traffic if you separate your VOICE devices from your DATA/LAN.
Access to specific clients, would be on your system's firewall if setup.

they are trying to forward voicemail messages to our email accounts using a dedicated email account vmail@ourcompany.com
here is a snap shot of the interface to setup smtp. We also tried the certificate name instead of the internal IP and also the external IP for the "Mail Server"

Ok, but what is being setup as the destination mail server? Do they use a PUBLIC mail.somedomain.com as the destination, in which case you would need to grant on the external firewall access from the 192.168.1.8 to the outside (outbound) rule.
If you want access from the toshiba directly to your local exchange, make sure the internal routing (VLAN/ACCESS/local firewall on the exchange server) allow 192.168.1.8 to connect, and if no authentication is included in the configuration, allow 192.168.1.8 to relay through your Exchange server.

443 is not a valid port for Mail exchange. Port 443 is a secure web port (........)

The port for 192.168.1.26 should be 25 without SSL. Default SMTP port. If your setup is (exchange console) is such that you have incoming SMTP connector set to a different port, use that other port in the configuration of the Toshiba.
If you want an SSL connection, use port 456 and make sure your exchange has a connector that is using encryption on port 456 or any other port.
If your exchange server allows TLS, you can check that box and either use port 25 or 587 provided your exchange server has either/both of these ports configured.

Please note that you have a test section, check your settings and generate a test message until you succeed.

To simplify further, open your email client, and look at the account configuration there..
Match the toshiba configuration to the one reflected in the email client you use that works.
Presumably, your email client is configured to talk to the exchange server...

Where do I check for my Default SMTP port?
If I open Exchange Management Console and go yo Server Configuration and select the properties of the severname I don't see what port I'm using

I see under Hub Transport
"Use these local IP addresses to receive mail"
192.168.1.26 port 25
"Receive mail from remote servers that have the these IP addresses"
192.168.1.0-192.168.1.68.0
192.168.1.2-192.168.1.255

Do I simply add 192.168.1.8 to
"Receive mail from remote servers that have the these IP addresses"
then use port 25 on the Toshiba smtp setup?

thanks I made a relay connector and it works now
