## BusinessPhone SoftNode

## Definition

The BusinessPhone SoftNode is a Software application that offers the possibility to connect H.323 clients via a IP connection to the ASB 150 02 IPU board.

The BusinessPhone SoftNode is only used for ASB 150 02 R12 systems as interim solution to offer the connection of H.323 clients.

The SoftNode is replaced by ASB 150 02 R13 which will support a direct connection of H.323 terminals to the IPU.

## Use

From ASB 150 02 point of view the application, which runs on a Windows NT 4.0 workstation, acts like a virtual ASB 150 02 node. The H.323 clients being connected to the SoftNode are handled like normal CN-extensions

Acting as virtual node the “SoftNode” supports following functions:

### Gateway service

The Gateway service offers a H.323 interface towards the IP-Clients and a proprietary Q-SIG interface towards ASB 150 02 systems.

### Gatekeeper service

The Gatekeeper service handles the registration and administration for use of H.323-clients on a number-plan based system that is needed for the use with
ASB 150 02. It also offers the possibility to make calls between two H.323-clients without any involvement of the ASB 150 02 system.

Additional proprietary functions are added to the Gatekeeper to offer an open number-plan towards the Gateway which is needed for external calls and to resolve IP-Addresses back to Phone Numbers.

H.323 Clients register itself to the Gatekeeper with their Phone-Number and a defined Password to avoid missuse.

### Connection of H.323 clients

The functions of the SoftNode are only ensured for the H.323 clients listed below. No warranty is taken when other clients are used.

- MS NetMeeting Version 3.01 (Current Version)
- BackStage

### Supported telephony functions

- Basic Call
- Calling Number Presentation
- Connected Number Presentation
- Calling Name Presentation (with Q-SIG or UUS)
- Connected Name Presentation
  (with Q-SIG or UUS)

## Operation

### Calls from ASB 150 02 to the H.323 client, towards the Softnode

This calls will be treated like any other CN call with the difference, that it is not possible to activate any system function from the A-party, if the B-party in the SoftNode is busy ( e.g. Call Back, Camp on, Intrusion).

If the client application is not running at the user side, the A-party will receive the blocked tone.

If the SoftNode is not active, the A-party will receive the number unobtainable tone.

### Calls from the H.323 client, towards the SoftNode to ASB 150 02

To set up or to receive a call from/at the H.323 client, the application has be started, in oder to get registered at the SoftNode. If the SoftNode will be shutdown due to unknown reasons although clients are active, the clients will not be informed about the shutdown as far they are not intending to setup a call. When the SoftNode is running again, all previously registered clients are reachable again without having to restart the application again.

#### BackStage

See dedicated userguide on the Product CD-ROM FASBS 102 209

#### MS NetMeeting

Start the NetNeeting application, depending on your configuration from the Start-menue or via shortcut from your desktop.

After startup, the cursor is positioned automatically in the address dropdown listbox to enter the desired number.

##### Setup a call

- Enter a new number or click on the arrow to select one of the recently dialled numbers.
- Click on the button to setup the call

- When the B-answers the call, the connected number will be presented.

- In case the B-party is busy or does not answer a separate dialog pops up, informing about the current status.

- To terminate the call, click on the button

For further details to MS NetMeeting see dedicated Helpfile.

## Capacity

A maximum number of 1000 nodes (ASB 150 02 and SoftNodes) can be covered by a customer network.

## Limitations

As the H.323 standard only supports Basic Call as telephony function, the client can only be used to setup and to receive a call, all other ASB 150 02 system functions are not supported.

Although there is no limit in the number of connectable H.323 clients to the SoftNode, the number of bidrectional voice channels towards an ASB 150 02 node is limited to 8.

In case of SoftNode internal traffic between the H.323 clients, there exists no limitation.

As the SoftNode will be handled as any other ASB 150 02 node the number length of the H.323 clients is limited to a maximum of 8 digits.

From bandwith point of view, the SoftNode is only be intended to used on a customer LAN/WAN environment and not in the Internet.

## Programming/Installation

### ASB 150 02

From ASB 150 02 point of view the SoftNode will be handled in the same way as any other ASB 150 02 node which is connected to the network via VoIP lines, therefore see document Networking via VoIP lines (366/15534-ASB 150 02 Uen) for detailed programming.
