VPN (Virtual Private Networking) is a technology to connect an external PC over an existing Internet access using a secured and encrypted data connection.
Page 83: Comfort Pro S In A Lan With An Ip-Enabled Server
In many cases, an IP-enabled server configures the IP settings via DHCP for all workstations. In networks in which the IP settings are made manually, you have to enter the corresponding IP settings in the Comfort Pro S Configurator (NET Configuration: LAN menu). Additionally you should change the DHCP server to static address assignment (in the NET Configuration: LAN: DHCP Server menu) to enable the Comfort Pro S, for example to configure connected VoIP system telephones.
Page 84: Internet Access
Internet Access You can also use the Comfort Pro S as an Internet access server in a LAN with an IP-enabled server. To do this, you must enter the Comfort Pro S IP address on the server as the default gateway. In addition, you must edit the internal DNS server configuration so that the resolution of external DNS names is forwarded to the Comfort Pro S.
Page 85: Ras Access
RAS Access In a LAN with an IP-enabled server you can also enable external computers to dial in via the Comfort Pro S. To do this, you should coordinate with the network administrator the IP address space which can be assigned to an external computer dialling in, and enter it in the Configurator, NET Configuration: RAS: PPTP/IPSEC/ ISDN menu, under Address Range.
Page 86: Branch Link
In case of a VPN connection, both Comfort Pro S systems use an Internet connection to transfer data. For encryption, the protocols PPTP (Point to Point Tunneling Protocol) and IPSec (Secured IP) can be used. In case on an ISDN connection, you configure two Comfort Pro S systems so that they can dial in to each other.

The required network topology (distance, connection capacity) determines which type of point-to-point connection is most suitable. A Q.SIG-IP network connection can be established using a fast VPN connection.

L1 sync possible has been activated, then one of the ports is automatically defined as the L1 clock source. The Comfort Pro S will automatically switch the clock source to another port configured as an L1 clock source (if a line fails, for example).
Page 116: Types Of Point-To-Point Connections
PBX Networking Types of Point-to-Point Connections Example: In the above case you could reverse the L1 slave/master setting for the connection between PBX 1 and PBX 3. However, if you then activate the setting L1 sync possible for the port of PBX 1, this may cause parts of the PBX network to stop functioning temporarily.

Page 123: Team Functions
Introduction Team Functions Team Functions Introduction With the team functions you can manage your telephone communication tasks by assigning lines with sep- arate call numbers to the keys of different terminals. The terminal users, or team members, can thus pick up one another’s calls or telephone each other using the configured keys.
Page 124 Team Functions Introduction The following keys can be used: ■ Trunk key: Calls (for the programmed call number, e.g. 11) are signalled to this key, and you can make internal and external calls via this number. A trunk key can be programmed with a substitute function (with another team member acting as the substitute).
Page 125: Team Configuration
Direct call keys, for example, can be configured at a terminal in a conference room to call the secretary. Team Configuration You can create teams and programme call keys in the Configurator of the Comfort Pro S (PBX Configu- ration: Groups and Ports: Upn menu).
Page 126: Examples Of Use
Team Functions Examples of Use Examples of Use The following examples illustrate the various uses of teams and team functions. For information on the display texts and how to use the individual functions, refer to the chapter “Managing Calls in a Team” in the “Comfort Pro P 100/300/500” user guide. Executive/Secretary Team In this example, the executive/secretary team comprises two members: the executive and the secretary.
Page 127 Examples of Use Team Functions The executive can be reached on the call number 10 (trunk key TrK 10: executive’s office). He can also answer calls from his parallel telephone. In addition, a private line is configured for both of the executive’s tel- ephones (trunk key TrK 12: private).
Page 128: Three-Member Team
Team Functions Examples of Use Three-member Team The three-member team described here is an example of a team configuration within a project group, e.g. export sales. Each team member has one Comfort Pro P 300 system telephone with all call keys programmed as trunk and team keys.
Page 129: Unified Team
Examples of Use Team Functions Line Busy Indication If a line is busy, e.g. TrK 11 Johnson, the team keys 11 on Miller’s and Smith’s telephones will indicate this. Call Signalling In this example, calls via the trunk keys are signalled acoustically. Calls via the team keys are indicated by a visual signal (the team key LED flashes).

Page 133: Call Queue
Calls in a queue are handled by the Comfort Pro S in the following order of priority: instant connection, door calls, automatic recalls, VIP calls, then other internal and external calls. Sensor calls thus have priority over other calls, for example.
Page 134: Activation Of Queues
Call Queue Introduction Queues can be combined with the “call forwarding,” “pickup” and “hunt group” functions, for example, in order to configure an enquiry station for an operator. Activation of Queues Queues can be activated on a per user group basis. On delivery the default set, for all preset groups, is off. When using queues, it often makes sense to activate call waiting protection.
Page 135: Pickup
Examples of Use Call Queue Pickup The functions “Pickup from group” and “Pickup selective” can be used together with queues. A user who accepts a call using “Pickup from group” or “Pickup selective” picks up the next call from the queue. Hunt Groups Hunt groups of the “parallel”...

Page 140: Configuring And Managing Companies
Configuring and Managing Companies Up to five companies can be configured in the Comfort Pro S. By default, one company with the name “Company 1” is predefined. All configuration settings, e.g. in the user groups or in the bundle configuration, apply to this predefined default company if not other company has been selected.
Page 141: Assigning Bundles/Sip Accounts
To be able to correctly transfer incoming calls to the members of the configured companies (the users) via the lines of a certain bundle of the Comfort Pro S, each of the available bundles must be assigned to one of the companies. This is necessary to be able to transfer incoming external calls to the correct company exchange in cases where the called internal subscriber cannot be reached (“Connection to...
