What is a SIP Trunk?

MessageBird SIP Trunking offers you the possibility to place outbound voice calls from your VoIP platform to phones anywhere in the world. A SIP-trunk makes calls via the public internet or a private IP-connection. Our SIP-trunks run authentication protocols on your IP-addresses and/or username-password combination.


You can set up accepting inbound SIP-calls with the Flow Builder.
