In one exemplary embodiment, a method, performed by a second node of sending a Session Initiation Protocol (SIP) message in a SIP-based communications network from a first node to a third node using the second node, may include receiving, by the second node acting as a SIP proxy, from the first node, the SIP message. Further, the method may include determining routing information for forwarding the SIP message to the third node. Also, the method may include sending, by the second node, to the first node, a pivot request to request that the first node forward the SIP message directly to the third node without traversing the second node. The pivot request may include the routing information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, system and network nodes for performing a sip transaction in a session initiation protocol based communications network","description":"Methods, systems and network nodes for performing a SIP transaction are provided.
