CRM integration and porting are named, which is unusual
Most listings in this directory say hosted PBX and stop. Du Pont Solutions names CRM integration, number portability and international virtual numbers as distinct capabilities, and each answers a question a real buyer asks. CRM integration decides whether your team sees who is calling before they answer. Portability decides whether you keep the number on your invoices and signage. International virtual numbers matter if you want a local presence in another market without an office there. Ask which CRM systems are actually supported, since that varies enormously and the effort is in the specific integration rather than the principle. The 24/7/365 support claim sits next to published weekday office hours, so establish what after-hours cover genuinely means before relying on it. Compare alternatives in the VoIP provider directory.
Who Du Pont Solutions is a fit for
- Businesses that need the phone system talking to their CRM
- Companies wanting a local presence in another country via virtual numbers
- Randburg offices consolidating voice, IT, security and power

Which CRM systems does Du Pont integrate with?
The site names CRM integration as a capability without listing supported systems. Effort varies enormously by platform, so name yours early and ask for a specific answer rather than a general assurance.
Can I keep my existing phone number?
Number portability is listed as a named service, which means moving your existing numbers should be possible. Confirm the timeline and whether any number cannot be ported, since that occasionally happens with older ranges.
What are international virtual numbers for?
They give your business a phone number in another country that rings at your South African office, so customers there dial a local number. Ask which countries are available and what each costs monthly.
Is support really 24/7?
Support is advertised as 24/7/365 while office hours are published as weekdays 09:00 to 17:00. Ask exactly what after-hours cover includes, what the response time is, and whether it costs extra.
Where is Du Pont Solutions based?
Du Pont House, 382 Kent Avenue, Ferndale, Randburg. The company’s Google profile confirms the same address.
What does it cost?
No pricing is published. Ask for the monthly per-extension charge, per-minute call rates, any CRM integration cost and handset prices as separate figures, especially if IT or security services are quoted alongside.
