Figure 4.2 shows the contributions made by PSTN and VoIP services to the decline of the overall fixed-line voice service index in 2013−14 after adjusting for revenue weights. PSTN services were the main driver behind the decrease in the fixed-line voice index.

Real prices fell for each component of the fixed-line voice service in 2013−14 (table 4.2). Notably, real prices for international and fixed-to-mobile call prices decreased 24.7 and 10.5 per cent respectively, with the international call prices decrease the largest decrease in this decade. Table 4.2 also shows that real prices have fallen every year for the call components of fixed-line voice services since 2004−05.

Figure 4.3 shows the contributions made by each component to the decline in the overall fixed-line voice service index in 2013−14 after adjusting for revenue weights. Basic access and fixed-to-mobile services were the main drivers in the overall price decline in 2013−14.

4.2 PSTN sub-index
The PSTN services sub-index is derived from average real prices paid for two types of PSTN services—residential and business PSTN services. There are also two components to PSTN business services—small business and other business.
4.2.1 Price movements in the overall PSTN sub-index
The PSTN sub-index has declined by 49.8 per cent (in real terms) since the base year (1997−98) (figure 4.4). During the reporting period, average real prices of residential and business PSTN services declined by 5.5 and 4.7 per cent respectively.

Real prices decreased across each service component of the PSTN sub-index in 2013−14 (table 4.3). International and fixed-to-mobile call prices fell significantly in the period, with year-on-year international call price reductions the largest in the decade.
