Reaching customers, not just answering the phone
The shape of this business is worth reading carefully, because it is not a straight hosted PBX supplier. Grandcom pairs telephony with a dialler and bulk mobile messaging, and its own framing is about increasing contact ratios. That is the language of collections, sales and service operations that need to reach large numbers of customers and prove they tried. If you are running an outbound team, the useful questions are dialler licensing, how call outcomes are reported, and whether messaging and voice sit in one system or two. WASPA membership matters here in a way it would not for an ordinary phone provider, because bulk messaging in South Africa is governed by that code and non-compliance is a real commercial risk. If what you actually want is fifteen desk extensions and a switchboard, this is a heavier tool than you need, and a straightforward cloud PBX provider will be a better fit.

Who Grandcom is a fit for
- Outbound sales, collections and service teams that dial at volume
- Businesses combining bulk SMS or email with voice campaigns
- Operations that need call outcome reporting rather than just extensions

Say whether this is inbound, outbound or both, and give the agent count, because dialler licensing is priced differently from desk extensions. If bulk messaging is part of the plan, state the monthly volume and ask how consent and opt-outs are handled under the WASPA code.
