Understanding VoIP
You will be able to use your V100 ATA to make and receive calls depending on the type of VoIP plan
you subscribe to. In the below examples you have connected the V100 ATA to your standard
telephone handset and Broadband Internet Connection, i.e. Cable or DSL service.
1. VoIP Subscriber to VoIP subscriber on the same VoIP network.
In a basic VoIP plan you are issued with a virtual VoIP (telephone) number which allows you to
make and receive VoIP calls to other subscribers on the same VoIP service normally free of
charge.
2. VoIP Subscriber to VoIP subscriber on a different VoIP network.
With most VoIP plans you are not able to make VoIP to VoIP calls between different VoIP
networks unless your VoIP provider has setup a special provision for this to occur (i.e. VoIP
Gateway between networks).
However, some ATA’s such as the V100 can be configured manually to operate in a Peer-to-Peer
mode where the user sets up a series of quick dial numbers on their ATA to correspond to the IP
address of the VoIP user they wish to call on the alternate network. The other VoIP user must
also configure their ATA to operate in the same mode to accept your VoIP call. For further
configuration information please refer to ‘Telephone Book Tab’ section in this guide.
3. VoIP Subscriber to PSTN Telephone.
In this example you are able to make the same calls as described in 1 & 2.
You are also able to make calls to real world telephone subscribers - local, Interstate and
International. However, you are not able to receive calls from real world telephone subscribers as
you only have a Virtual VoIP (telephone) number.
4. PSTN Telephone to VoIP Subscriber.
In this example you have subscribed to a VoIP service plan that also provides you with a real
world telephone number instead of a virtual VoIP (telephone) number. Normally this type of
VoIP service plan has a monthly subscription fee.
With this plan you are able to make and receive calls to and from other VoIP subscribers on the
same VoIP service. You are not able to make VoIP to VoIP calls between different VoIP networks
unless your VoIP provider has setup a special provision for this to occur (i.e. VoIP Gateway
between networks).
You are also able to make and receive calls to and from real world telephone subscribers, local,
Interstate and International.
