Abstract
A method is performed by a session initiation protocol (SIP) user agent or a SIP proxy. A SIP packet is received and parsed into fields. The fields are written into an outbound packet being a protocol packet or a protobuf packet, wherein writing the fields is dependent on an application programming interface (API) for integrating with the SIP user agent or SIP proxy, and wherein the API has restricted functionality as compared with SIP. The outbound packet is sent to a node that implements a service and which has access to the API definition. A response is received and the SIP packet is edited according to fields in the response to produce an edited SIP packet. An action is determined to apply to the edited SIP packet, according to the response. The action is applied to the edited SIP packet.
