SMARTalk is a VoIP application for iPhones that allows users to save money on their calls. By using a 050 phone number, users can reduce call charges to both mobiles and fixed phone lines.

The SMARTalk application comes pre-configured with optimal settings for easy usage. Users simply need to enter their SIP account information and password to start using the SMARTalk service.

One of the standout features of SMARTalk is its noise-canceling capability. This feature cuts out background noise during phone calls, resulting in clearer and more enjoyable conversations.

Another useful feature is the ability to record and play back calls made with the SMARTalk application. This can be handy for keeping track of important conversations or for reference purposes.

Additionally, the SMARTalk application is designed to minimize battery usage. It can receive phone calls via push notification, even when the application is not running in the background. This helps to save on battery life, although the push notification may be subject to delays depending on the network situation.

Some of the main features of SMARTalk include a 050 IP phone number, answer phone service with automatic email notifications, push notifications for incoming calls, call recording, mute, speaker, and hold options, speed dial, customizable ringtones, and Bluetooth support.

However, it is important to note that there are certain limitations to the service. Calls cannot be made to emergency numbers (110, 119) or free dial numbers (0120).

Before using the SMARTalk application, users are advised to carefully read and understand the terms and conditions regarding its use.
