The wireless signal can be affected by network traffic and signal interference, potentially impacting call quality. On the other hand, fixed VoIP ensures a clear voice quality even during peak hours.

2) Affordability: Fixed VoIP is an affordable option for businesses as it eliminates the need for a traditional Public Switched Telephone Network (PSTN) infrastructure. It requires just an internet connection, which is widely available nowadays. As compared to mobile VoIP, fixed VoIP is more cost-effective in the long run.

3) Reliability: Fixed VoIP is more reliable than mobile VoIP as it is not affected by network issues that may disrupt phone lines. In contrast, mobile VoIP may be disrupted by signal obstacles, network failures, or even bad weather conditions. It is easier to maintain fixed VoIP and ensure that you have a constant, reliable connection.

limitations of fixed VoIP over mobile VoIP 

1) Limited Mobility: Mobile VoIP allows businesses to access communication from anywhere, provided they have an internet connection. This is convenient for individuals who often travel or work from different locations. In contrast, fixed VoIP restricts communication to a particular location and is not recommended for people who require mobility. 

2) Infrastructure: Implementing fixed VoIP requires infrastructure, which can be lengthy and complicated. Businesses may need to install new wiring, equipment, and other costly investments, which can be a limitation for small businesses.

In selecting the ideal VoIP solution for your business, fixed VoIP is advisable for businesses that prioritize reliability, quality, and security, while mobile VoIP is suitable for businesses that require mobility and flexibility. Ultimately, it’s important for your business to carefully consider each type of VoIP before selecting the most appropriate one for your needs.
