BT Wholesale and NEC in the UK have completed interoperability testing to certify the use of NEC's communication servers on the BT Wholesale SIP Trunking (WSIPT) platform.
WSIPT is a secure, cloud-based IP voice solution, used by businesses of all sizes.
The certification confirms NEC as an approved equipment vendor for the WSIPT platform and covers the SL1100, SV8100 and SV9100 award winning communication servers.
Gemma Hutchins, Senior Product Manager at BT Wholesale, said: "This opens up a huge area of the market to our resellers as NEC are one of the major communication vendors in the UK."
WSIPT is built on BT's strategic ISDN replacement platform within the heart of the BT 21CN core network and has the capacity to handle anything from one to 10,000 SIP channels.
