VoIP Trunk
Yeastar S-Series supports SIP and IAX protocols and provides 2 types of VoIP trunks:
VoIP trunk:
registration based VoIP trunk. A VoIP trunk requires S-Series to register with the
provider using an authentication name and password.
Peer To Peer:
IP based VoIP trunk. A
“Peer To Peer” VoIP trunk does not require S-Series to
register with the provider. The IP address of S-Series needs to be configured with the provider, so
that it knows where calls to your number should be routed.
Go to
Settings > PBX > Trunks
to add a VoIP trunk.
