Here is the comparison between the two keeping in mind the quality of the services and the features offered by them both:

VoIP GSM
Compatibility The system uses modern advanced technology. It enhances the business capabilities. GSM uses an old cellular technology and it doesn’t update as VoIP does for business development.
Hardware The hardware needed is quite less in comparison to GSM. Integration is possible by directly connecting to your PBX. GSM would need additional hardware installation. It cannot be integrated with existing hardware and systems.

Connectivity VoIP doesn’t need mobile coverage. It works with any internet connection or a dedicated VoIP line. GSM requires a mobile network coverage in the area, without this it will not work.
Call Rates The VoIP calls rate can be reduced substantially. The call rate cannot be reduced as it is in the case of VoIP
Quality The quality of calls is excellent. Blazon offers a 99.9% uptime rate. The quality of calls is not as crystal clear as internet calls.
