Get business landline number on your SMARTPHONE

Perfect for small businesses and start-ups

Time to cut the cord on your office desk phone

The phone is an indispensable channel of communication. However, the days of office desk phones are fast fading away as more businesses switch to Internet-based telephony solutions or Voice over Internet Protocol (VoIP) such as REDtone SIPhony.

Designed specifically for SMEs, small businesses and start-ups, REDtone SIPhony offers a full suite of features in app form. You can choose to subscribe only to those that meet your current business needs.
