How to use SmartNode™ VoIP Gateways with Aastra 800

Introduction
The Aastra 800 is an innovative call manager and IP-PBX, which is not hardware dependent and therefore does not require proprietary ITC hardware. Instead, this powerful communication server can be installed on any standard Windows™ PC.

Since a standard Windows PC does not provide ISDN interfaces, an external VoIP gateway is required to connect the Aastra 800 to the PSTN. This page shows how to configure Patton SmartNode™ VoIP equipment to perform the external VoIP gateway function.


As shown in the above drawing, SmartNode™ provides connectivity and protocol conversion between the Aastra 800 (SIP signaling) and the PSTN (ISDN signaling).

Prerequisites:

•	A running Aastra 800 installation
•	A SmartNode™ with R5.3 firmware (see applicable models) OR a SmartNode™ with firmware R5.2 and installed SIP Registrar license (order code SNSW-REG). R5.3 and above already include this license and allow registration of up to three Aastra 800, thus R5.3 is recommended.
•	An ISDN PSTN connection (MSN and DID connections are both OK).

Step-by-step instructions
The following sections describe how to configure a SmartNode™ for use with the Aastra 800 call manager. First a basic set-up example is presented, followed by a fax handling example.

Basic use case: Aastra 800 with SmartNode™

1. Download the SmartNode™ for Aastra 800 Configurator spreadsheet

2. Open the spreadsheet and enable macros

3. On the first sheet named “Parameter Control”, type in the parameters of your installation.

a. Set the LAN IP Address (ETH port 0/0 on the SmartNode™) according to your network topology. If your SmartNode™ has a second Ethernet port, it won’t be used.

b. Set the Aastra 800 parameters according the configuration you made on the Aastra 800 configuration interface. The choice of user name, password and domain is yours, they just have to match between Aastra 800 and the SmartNode™

c. Select MSN for “Mehrfachanschluss” and DID for “Anlageanschluss”, which specifies what type of ISDN connection you have. All ISDN interfaces are configured the same way
.

4. Click on the sheet in green color that has the name of your SmartNode™ (e.g. “SN4554”). This sheet will contain an automatically generated configuration file that works with Aastra 800.

5. Hit the button labeled “Export this configuration” and save the configuration to your computer. If the button doesn’t work, you didn’t enable macros in step 1. In this case, you can save the spreadsheet in text format using “Save As”.

6. Start the SmartNode™ and connect it to the LAN on port 0/0. There has to be a DHCP server on the LAN for this port to become active.

7. Use the SmartNode™ discovery tool (get it here) to find your SmartNode™.

8. Open the SmartNode™ web interface by double-clicking on the entry in the discovery tool

9. Import the configuration file into the SmartNode™ clicking on “Import/Export” on the web interface, then “Import Configuration”


10. After import, you will be prompted to restart the SmartNode™. Doing so will activate the uploaded configuration.

11. The SmartNode™ should now register with the Aastra 800. You can verify the registration using the web interface of the Aastra 800.


Advanced Use Case: FAX Handling

Aastra 800 doesn’t support fax as of November 2008. The SmartNode™ can be used to identify fax calls and split them from regular voice calls. The identified fax calls can then be sent directly to a fax server or fax gateway.

You can use the following Patton products as fax gateways to connect a fax machine to the VoIP network:

•	SmartLink M-ATA – one fax, modem device or analog phone
•	SmartNode™ 4110 Series – up to 8 fax, modem devices or analog phones

Configuration file templates

Here are some prepared complete configuration files (.txt) for your reference and use. These files support additional use cases that the auto-configuration tool does not cover:

•	SmartNode™ 4554 basic use case
•	SmartNode™ 4638 basic use case
•	SmartNode™ 4638 two fax numbers routed to two separate fax devices

Applicable Patton SmartNode™ models for use with Aastra 800

ISDN BRI lines
Patton ISDN BRI gateways are available in models that provide from 1 to 4 BRI interfaces. Corresponding call capacities are 2 to 8 simultaneous calls (each BRI interface supports up to 2 simultaneous calls).

BRI Lines	Call Capacity	Model Number	Notes
1	2	SN4552/2BIS/EUI
2	4	SN4554/2BIS/EUI	Best value
2+1	4	SN4634/3BIS/EUI	More versatile than the SN4554/2BIS/EUI, but higher priced. Includes a bonus third ISDN port for migration options
4+1	8	SN4638/5BIS/EUI	Includes a bonus fifth ISDN port for migration options

ISDN PRI lines
Patton ISDN PRI gateways provide 1 or 4 physical PRI interfaces. The model code indentifies the call capacity of each gateway, ranging from 15 to 120 voice calls. By selecting the model with the capacity closest to your requirements, you only pay for the capacity you need.

PRI Lines	Call Capacity	Model Number	Notes
1	15	SN4960/1E15V/UI
1	30	SN4960/1E30V/UI	Best value
4	15	SN4960/4E15V/UI
4	30	SN4960/4E30V/UI	More versatile option
4	60	SN4960/4E60V/UI
4	120	SN4960/4E120V/UI

Since call capacity is regulated by software, it can be increased by purchasing the comensurate software license. Because the PRI interface can be software- configured as E1 (Europe, South America, etc.) or T1 (US, Japan, etc.), SmartNode™ PRI gateways and IADs can be deployed anywhere in the world.
