As long as it supplies what is needed (correct, anonymous.invalid, incorrect, ...), the basic answer is that a device can use whatever logic it wants to generate the From's sip-uri host. Even though it might be preferable to have more configuration options, the ones mentioned can work for some deployments. > Also, should the UAC who finally receives the request through > the outbound proxy bother about the hostname part of the FROM URI? Since the From sip-uri host can be part of the identity, yes the called party might want see who is supposedly calling. As an fyi, an outbound "proxy" might actually be a B2BUA which changes the From header. _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
