Differences between ToIP and VoIP?

Similar but distinct technologies

Differences between ToIP and VoIP?ToIP ("Telephony over IP" or "telephony on IP") and VoIP ("Voice over IP" or "Voice over IP") are 2 professional fixed telephony solutions that are not always well distinguished. The 2 work thanks to the Internet protocol IP, it is at the level of their field of action that the differences are to be sought. VoIP operates on voice signal transmissions between the company and the central switchboard of the telephone operator. ToIP is a telephony system that is limited to the local IP network. It is therefore a simple router creating the connection between the LAN network (company) and the WAN network (operator) which differentiates these 2 telephony solutions.

To function, a ToIP network needs IP telephone sets (or IP-Phones), an IPBX telephone switchboard, IP adapters for analog stations as well as an IP gateway to PRI which will establish the connection to the network. fixed telephony from a traditional operator.

The hardware needed to operate VoIP differs somewhat. A company wishing to benefit from this technology must equip itself with IP adapters for analog or digital terminals, an IP Centrex, an operator's software auto-switch and a Media Gateway connecting the operator to others. operators.

Two compatible systems?

VoIP and ToIP have a common language which should in theory guarantee their interoperability: SIP (Session Initiation Protocol). In reality, this is not necessarily the case because the manufacturers of fixed telephony equipment for professionals are retouching the SIP protocol in order to optimize it. ToIP / VoIP relay is therefore possible without being automatic.
