How do I configure a Panasonic KX-KDE/NCP SIP trunk?

Trunking between a Panasonic PBX and GoTo Connect allows your current hardware to use their existing functionality, while adding some additional cross-platform functionalities with GoTo Connect phones.

Note: This guide assumes that the reader is comfortable with configuring a Panasonic BTS system. As it only entails registering the KDE/NCP device to GoTo Connect to receive calls and ensure proper call handoff.  Any other PBX configurations – such as licensing and routing decisions (hunt groups, schedules, etc.), would need to be configured separately by the reader. It also assumes that the reader has been provided the SIP credentials that are required to register and connect with GoTo Connect.

First, connect to the PBX.

  1. Start the Panasonic Unified Maintenance Console.
  2. Click Connect, verify that you will be doing so at the INSTALLER level and choose the method of connection:
    • LAN
    • RS-232
    • Modem
    • USB to Connect to your PBX for interactive configuration
  3. Provide the IP address of the MPR card and the password of the INSTALLER Level.
  4. Click Connect.

Second, set/verify the IP Settings.

  1. From System Menu > Configuration > Slot, hover over the MPR card and select the card property.
  2. If static addressing is desired (DHCP Client enabled is fine as well) – the default gateway should be the end router LAN IP address. Also make sure that you have a valid DSP-VOIP LAN address.
  3. Click Apply > OK.

Third, install the V-SIPGW16 card.

  1. From Configuration > Slot, hover over the IPCMPR Virtual Slot and click Select Shelf.
