PSTN-to-VoIP Services

This is part of a full-service VoIP plan that also provides a real-world telephone number

instead of just a virtual VoIP (telephone) number. Normally these plans have a monthly

subscription fee and enable you to make free calls to other subscribers on the same VoIP

service and also to make and receive calls from PSTN numbers local, Interstate and

International through a ‘gateway’ service. Charges made for calls going through the

Gateway service are a fraction of normal PSTN service charges, hence the saving

What is SIP?

You will often see references to SIP or SIP Service Providers. SIP is the Internet protocol

which manages VoIP connections; a VoIP Service Provider will have a ‘SIP Server’ which

maps device IP addresses against telephone numbers and enables the connection to be made

between PSTN and Internet. For more information, check the NetComm website.
