1. A method performed by a function in a network node in a telecommunications network having a plurality of service communication proxies, SCPs, deployed between a first network node and a second network node, the method comprising:
receiving, from a first SCP of the plurality of SCPs, a request for a next hop identity to signal a message from the first network node to the second network node; and
responsive to the request from the first SCP, providing a response to the first SCP, wherein the response identifies at least a portion of a routing path for the message based on a routing path configuration, and the response includes the identity of a second SCP of the plurality of SCPs.
