5. Adding lines hosted by a VOIP Provider.
Introduction
VOIP providers “host” phone lines – they can assign local numbers in one or more cities
or countries and route these to your phone system. In addition, VOIP providers are often
able to give better call rates because they have an international network or have
negotiated better rates. Therefore, using VOIP providers can reduce call costs. However
be aware that each VOIP call requires bandwidth. VOIP is real time, so it does place a
demand on your internet connection. As a rule of thumb, each call will consume
approximately 30k-120k per second, depending on which codec you use. This chapter
describes with which VOIP providers you can set-up an account and how to configure
3CX Phone System accordingly.
Step 1: Create an account with a VOIP Provider
To add a VOIP line you need to have an account with a quality VOIP service provider.
3CX Phone System supports most popular SIP based VOIP service providers and we
recommend using one that has been tested by 3CX. 3CX includes pre configured
templates for these VOIP providers. Simply click on the ‘Add VOIP’ link to see a list of
supported gateways.
Note that you can use any SIP based provider but we will not be able to support you in
the configuration of the VOIP provider, nor can we guarantee that it will work. Therefore,
unless for your country no VOIP provider is listed, use a supported VOIP provider.
Note that Skype has a proprietary protocol and is therefore currently not supported.
Step 2: Add the VoIP provider account in 3CX Phone System
After you have created the VOIP provider account, you will need to configure the account
in 3CX Phone System. To do this:
1.
In the 3CX Phone Management console click on the ‘Add VoIP’ link in the Lines
section in the left hand menu.
2.
In the name field, enter a friendly name for this VOIP provider account and choose the
VOIP provider that you are using. If it is not listed, select ‘Generic VOIP provider’, or
‘Generic SIP Trunk’. A generic SIP trunk is a provider that does not use an
authentication ID and password, but rather uses your IP as authentication. If using a
generic provider we will not able to guarantee that it will work with this VOIP provider.
