Hi Thomas: Please see below.

And certainly that is the case. The device knows it is behind a circuit switched connection. It doesn't know any address, not an E.164, or not any other addressing scheme (say, E.212). So, if it doesn't know it, let's signal it with a dash. I don't see the point in indicating that the devices knows it has an E.164 address allocated to it, when it does not really know it. /Miguel > Thomas > > -----Original Message----- > From: mmusic-bounces@ietf.org [mailto:mmusic-bounces@ietf.org] On Behalf > Of ext Miguel A.
