X-change
This is the generic brand for all VoIP based services and solutions provisioned by CMC on an international basis.
In simple terms X-change means Voice over X-cellence for your business!
Background to X-change
With CMC Networks IP Voice, available in South Africa since 2005, you can chose the voice solution you need, knowing that it will adapt to meet the changing needs of your organisation.
The service will support an integrated mix of legacy and IP PBXs, site-based (PBX) and IP centric network-hosted systems, digital and IP telephony equipment, call routing via both the public switched telephone network (PSTN) and a virtual private network (VPN), with guaranteed voice quality.
You can connect your current voice equipment seamlessly into a CMC Networks IP voice solution while maintaining a single dial plan (short-code desk-to-desk dialing), and without sacrificing any functionality, features or voice quality.
Our VoIP solutions will provide immediate savings once deployed and commissioned:
- You don't pay for usage if calls stay on your VPN (on-net calls) - all between-branch calls are covered by a flat monthly charge.
- Our rates for calls that break out to the PSTN (off-net calls) are very competitively positioned against Telkom's standard rates.
