Overview

Summary

Transnet seeks proposals for a Hosted PBX solution to enhance its telephony infrastructure nationally over five years. Key requirements include interoperability with existing devices, 24/7 support, and compliance with ICASA licensing.

Detailed Description

Transnet is inviting proposals for the provision of a Hosted PBX solution that will replace the current HPBX system while ensuring the retention and full utilization of existing telephony devices. This solution is expected to facilitate a seamless transition to a Microsoft Teams-based calling system, with less than 5% of devices remaining on the N-PBX solution. The contract will span five years, during which the selected service provider will be responsible for implementation, support, and maintenance of the new system.

Key requirements for bidders include the submission of a valid Electronic Communication Certificate (ECNS) from ICASA, proof of interoperability with Transnet's existing devices, and the provision of 24/7 enterprise support. Additionally, bidders must demonstrate valid OEM certification as an approved partner for the proposed solution and hold ISO27001 certification. The successful bidder will work closely with Transnet to ensure that the new telephony infrastructure meets the organization's business needs while delivering cost-effective and high-quality service.

Suitable Businesses

This tender is suitable for telecommunications companies, VoIP service providers, and IT firms with expertise in telephony solutions and a proven track record in managing large-scale communication projects.
