Adding Service Providers
You must configure a VoIP service provider to connect to the Public Switched Telephone Network (PSTN) via
a VoIP connection. Access to the PSTN gives you the ability to place calls to telephone numbers no matter
how they connect to the PSTN (VoIP or standard analog system). Click the Service Providers tab to add a
VoIP (SIP or IAX) service provider.
The list of VoIP service providers and corresponding configuration information is pulled dynamically from a
secure AMX webservice. If you are already a VoIP provider customer, select the provider from the list, click
Add,
and input your user name and password. Once you have added a service provider it will appear in the
Service Providers list. There are Edit and Delete buttons associated with each Service Provider listing. Click
Edit
to further refine your service provider definition. A detailed definition will be displayed.
The Edit Service Provider page gives you the ability to change your caller ID, as well as select a range of
codecs.
Click Update when you have completed your changes, or Cancel to discard your changes.
