New dtac OneCall service puts a full business phone system in your pocket

No installation required for this hassle-free, fully mobile solution from dtac Business

On 10 November 2020, dtac Business, a provider of communication technology and solution services for small to large businesses, has launched the dtac OneCall service for SME. It transforms any mobile phone into a full business phone system that can direct and transfer incoming calls just like a fixed-line private branch exchange (PBX)—but with none of the hassles of installation and wiring. Fully mobile and scalable, dtac OneCall is easy to use and cost-effective, allowing teams to communicate with customers seamlessly from their mobile phones.

Boost Sales Leads, Impress Customers

One significant SME pain point is unanswered incoming calls, and the loss of business they represent. But investing in additional employees and hardware to answer calls is both expensive and inefficient.

dtac Business designed dtac OneCall to transform any mobile phone into a business phone system where any employee can answer incoming calls from anywhere. It also makes internal communication between employees more convenient, and the call quality is excellent since dtac OneCall uses a native dialer which offers much higher performance than VOIP.

dtac OneCall is quick to install, all functions can easily be customized to individual preferences, and it keeps costs to a minimum, with monthly fees starting at only 149 Baht. Some of the main features include Interactive voice response (IVR) that can customize to suit day and night time service, Internal conference call and Instant messaging, Business Call Manager and Admin Portal for OneCall setup and report generation, and many more features within dtac OneCall.
