Settings to provide the best results and operation of the DuVoice system.
DV2000 supports Windows versions:
Configured under Folders Options in Control Panel.
The DuVoice service runs as a system account which does not require a user account. However the user account that administers the system must be an Administrator because they need this access level.
Don't create user accounts on the local system for any other users or reasons. This is after all your voicemail and hospitality server.
DuVoice has no backdoors or way of accessing the system if you forget your password.
There is absolutely no reason why the DuVoice system needs to be part of a domain. In fact almost every system which has been added to a domain has problems. Most of these problems are because the administrators may force policy changes to the local machine which can effect it's operation.
We recommend enabling the firewall and edit the settings to allow access to specific systems only. See our expanded configuration guide on the firewall here
DuVoice when installed will unblock all the ports it requires. However applications like PMS, Call Accounting and others will not. You will need to unblock these ports manually.
Another common problem is corporate firewalls between the DuVoice system and things like the PBX. It is common for these to block SIP connections after traffic has stopped. For example the firewall when it sees traffic between the PBX and DuVoice will open the ports necessary and then when traffic has stopped it will close them. This results in calls going unanswered.
There is no need to install Microsoft Office on the DuVoice system and it is preferred not to do so.
It is best to select High performance from the Control Panel power options, then edit this plan and make certain the following are set. Key thing is the system should never sleep and never hibernate for any reason.
Note: Not setting the system to not sleep can cause SIP and PMS interfaces which use the network to fail. This is due to the system putting the network adapter to sleep.
If the system is connected to a UPS make certain the system sleeps on power loss rather than hibernates.
DuVoice uses teamviewer for all remote access. This application is fully secure and provides the best remote security we've found.
RDP can be used internally to administer the system without any effects on the DuVoice system.
Automatic updates should be disabled. While a updates should be applied regularly and often they should not be automatically applied.
The DuVoice is a voicemail system requiring 24 hour up time, if automatic updates are enabled the system will apply the updates and may reboot right when all your wakeup calls are set to occur.
SIP systems are often disrupted by automatic updates because they interfere with the SIP stack and they system will look normal but no calls are answered.
DuVoice requires it's own web server and it is installed by default. It is possible to run multiple servers on the DuVoice however we suggest you configure each to use it's own network card.
It is strongly suggested the network connection be set to private. This must be done from Windows Settings.
When the system has multiple adapters and each is used for a different connection or use, it's recommended to rename each adapter to what it's used for. This will make diagnosis of any SIP or networking issues easier to identify.
