Thanks to:

Thanks to T&C Engineering and Mr.Gianni Carrera for helping us in creating this guide to Nortel BCM400 configuration and for giving us a sample Nortel BCM50 configuration.

1. Configure your Skip2PBX to accept trunking from your Nortel BCM50

Open your Skip2PBX web interface and go in Channels > SIP > SIP trunks and  create a new trunk with following specs:

Authentication mode	Based on IP (trusted)
Link mode	PBX
Username	bcm400
Remote Side IP	your nortel IP
Remote side port	5060
DTMF Mode	RFC2833

2. Configure your Nortel BCM50

See attachments.

3. Configure your Skip2PBX routes

Open your Skip2PBX web interface and go in Call routes > Inbound calls or Call routes > Outbound calls and define routes depending on your preferences.

Default outbound route works for 99% of configurations.

PLEASE NOTE: For incoming calls you may need to specify an extension number to route call to.
