The closest thing I can think of is S/MIME signatures and certificates that of course are encoded in text, but is not text in the data. There are actually references to sending images in RFC 3261:
"The disposition type icon indicates that the body part contains an image suitable as an iconic representation of the caller or callee that could be rendered informationally by a user agent when a message has been received, or persistently while a dialog takes place." Page 122, RFC 3261. Now, images can of course be encoded or sent binary. The RFC doesn't give us recommendations, so I guess you will have to track back to the original set of documents for MIME. (Surprised that Dave did not find that :-) ) /O _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
