VoIP Trunks
Path: Telephony -> Outbound Control -> Trunks
Asterisk PBX can be registered as a SIP user agent to a SIP proxy (provider). If you have subscribed to a VoIP service
from an ITSP (Internet Telephony Service Provider), then with the account details provided by them you can
configure a VoIP trunk on your IPPBX system for the user extensions to share and make outbound phone calls.
To implement your SIP trunk account on the IPPBX system, you’ll need to create a VoIP trunk.
Most of the trunk settings will be given by the service provider, settings that are not mentioned by the provider
you may leave them blank or use default values.
 Authentication: If the service provider doesn't require a username and password for this account to register
to their server then you can enable this option.
 Host: The SIP server domain or IP address.
 Username: Username provided by VoIP Provider.
