Risks
1. Security risks: VoIP adoption can open up systems to security risks, such as interference, hacking, eavesdropping and denial of service attacks.
2. Quality of Service (QoS) risks: Poor deployment and inadequate QoS can lead to voice-quality problems, such as dropped calls, jitter, and latency.
3. Regulatory risks: PCCW must ensure that the VoIP system complies with all applicable laws and regulations, such as extended 911 requirements.
4. Interoperability risks: VoIP signaling protocols may not be compatible with current PBX systems.
5. Scalability risks: PCCW must ensure that its system has enough capacity to support any potential growth in demand for the VoIP services.
6. Bandwidth risks: A VoIP solution may require additional bandwidth, which could increase the cost of the service.
7. Human resources risks: PCCW must also consider the impact that the new system will have on its human resources, such as the need to retrain existing personnel.
