No; that does not necessarily indicate the IP address (or set of IP addresses) of the INVITE sender. You can retrieve it from the Via sent-by or received. However, this assumes that a middle box (such as an SBC) does not strip or encrypt the prior Via entries. NOTE: if a middle box is hiding one side of the network, you will not be able to obtain the IP address of the original INVITE sender. _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
