Testing Enviroment

Scenario

This scenario describes a setup where the PBX and phones are in a private network. The provider supports NAT detection. As a result, the IP800 can work without a stun server.

Configuration

General Information

Firmware version

• IP800: 9.00 hotfix1
• IP22: 8.00 hotfix16 - build 805005400
• IP200: 9.00 hotfix1
• IP230: 9.00 hotfix1

SIP - Trunk

First of all the SIP Trunk must be configured. Make sure that Media Relay is activated.

Number Mapping

The complicated part on this issue is the correct mapping of the outgoing and incoming numbers.

Route Settings

Because Sewan, as most SIP - Providers too, doesn't support overlap sending, you must enable the blockwise sending of the phone number. You can do this by enabling Force enblock in the automatically generated Routes.

The second setting you must check is Interworking(QSIG,SIP). This feature must be enabled to properly relay supplementary services, like Hold over the SIP Trunk. If this checkbox is unchecked only basic call Information like connect and disconnect will be forwarded by the Gateway.

Fax

The FAX was connected via a IP22 to the IP800. When configuring the IP22 you must keep in mind that you will use the analog interface for fax communication. That's why the T.38 codec must be enabled.

CLIR

To suppress the CGPN for outbound calls a config line option must be activated. Please enter the following lines in your browser:

http://PBX-IP-address/!config write
http://PBX-IP-address/!config activate
