International phone calls have become cheaper with the advent of PC to Phone calls. As a matter of fact, the replacement of traditional phone service by Internet-based voice communications (VoIP) has been gradual yet effective. Several companies have come up in diverse parts of the world that offer a wide multitude of VoIP services that can be enjoyed using either a broadband or a dial up connection.
However, certain guidelines need to be followed while making pc-to-phone calls using dial-up connections. First and foremost, system resources need to be made free, by closing any program that is running in the background. Programs that are not critical to the system security should also be closed. However, anti-virus software and firewall applications do not fall in this category.
The Internet connectivity needs to be opened up to facilitate VoIP PC to phone calls. The limited data capacity of dial-up connections proves to be an impediment in this context. Call quality can be optimised by limiting the use of the bandwidth only for making calls. Other activities need to be suspended for a specified time. Checking of emails or browsing the Internet has to be abandoned, for instance, if one wants maximum clarity in the calls.
It is advisable for users to check their systems for viruses and adware that could have an adverse impact on the efficiency of the computer system. PC to Phone calls often involves annoying voice echoes. This can be minimised when the person making the call uses a headset with a boom microphone integrated in the same.
So, the fact that if you do not have access to broadband Internet does not mean that you cannot make cheap long distance phone calls. PC to phone calls are very much possible with a dial-up connection, albeit subject to some minor constraints.
