Hi Tarun, The record-route header field is actually a list of addresses. It is mandatory that every request or response between two UAs MUST pass via all the addresses in that list. So, if an incoming INVITE has a record route header then any response to it MUST have the same header in it, so that the response travels through the same path(in the reverse direction) through which the IINVITE came.
