Frequently Asked Questions

Yes, by installing a Vox supplied voice gateway we can connect to any PBX.

GNP (geographic number porting) legislation allows for the porting of geographic numbers (like 011, 021, 031, etc) to registered entities like Vox. Unfortunately, non-geographic numbers (like 0800, 0860, 086, 0871) cannot be ported at this time.

The solution is very scalable and dynamic. Can cater for up to hundreds of concurrent calls.

We offer redundancy solutions to cater for inbound and outbound calls. A standard feature is Call Divert, to allow for inbound calls to be diverted to alternative numbers.
