INTRODUCTION
This document describes the configuration procedures required for the NEC SL1100 and SV8100 IP-
PBX ranges to make full use of the capabilities of IPVS SIP Trunking.
These NEC IP-PBX’s are come of the many access products that interoperate with IPVS. They use the
Session Initiation Protocol (SIP) to communicate with IPVS for call control.
This guide describes the specific configuration items that are important for use with IPVS. It does not
describe the purpose and use of all configuration items on the SL1100 and SV8100, for those details,
see the relevant NEC documentation.
Interoperability testing validates that the device interfaces properly with IPVS via the SIP interface.
Qualitative aspects of the device or device capabilities not affecting the SIP interface such as display
features, functionality and performance are not covered by interoperability testing. Requests for
information and/or issues regarding these aspects should be directed to manufacturer.
