SIP server

The Federated SIP project is a set of scripts designed to run OpenSIPS + rtpengine in a way that will provide federated, open communication with any other SIP server on the internet.

Federated SIP Features

• SIP registrar with multiple domain support, including authenticated and unauthenticated users.
• Complete server side NAT handling for clients behind NAT.
• Federated SIP proxy server that follows RFC3263 for locating SIP servers.
• WebSocket, TCP, TLS, and UDP connectivity on IPV4 or IPV6.
• Media interop between DTLS-SRTP, SRTP and RTP
• Powerful regular expression based outbound translations for dynamic routing.
• Centos and Debian system set up scripts to turn a bare OS install into a full SIP system in a matter of minutes.

Installation

Federated-SIP has been updated to use ansible. Ansible allows you to manage remote hosts without needing to install any client software on the remote servers.

• apt-get install ansible or yum install ansible on your local machine.
• cp hosts.sample hosts and edit to include your servers domain or ip.
• cp variables.yml.sample variables.yml and edit to include your servers domain.
• run ansible-playbook -i hosts federated-sip.yml --extra-vars="firstrun=true"
• after ansible finishes, you can tell opensips about other domains this proxy hosts by running: opensipsctl domain add mydomain.com
• finally you can add users that will be able to register to opensips opensipsctl add [email protected] passwordforalice
• subsequent runs of ansible should be made with the firstrun variable set to false
• run ansible-playbook -i hosts federated-sip.yml --extra-vars="firstrun=false"

Ansible will automatically utilize the primary ipv4 and ipv6 address on your remote server. For more complex installations such as TLS, or WSS edit variables.yml to enable or disable specific options, and specify things like the location of private keys.
