PSTN's traditional multi-party teleconferencing system is the most widely used teleconferencing solution in domestic enterprises. It mainly adopts the multi-party calling platform provided by the teleconferencing company and purchases its own multi-party conference hardware equipment.
Their main differences are:
Conference service company platform | Company self-purchasing hardware conference platform |
No need to buy multi-party hardware devices, only occupy one outside line
| Need to purchase multiple hardware devices, may occupy multiple external lines
|
You may have to make an appointment in advance the meeting. Call stability is not good for self-purchasing equipment
| Self-owned equipment, ready to meet, more free time
|
To charge a monthly rent (annual rent), or to add an audio fee
| Calling standard telecom charges
|
Poor confidentiality
| Strong confidentiality
|
The service company has a risk of bankruptcy and has a certain risk of rent loss.
| No uncertain risks
