I didn't reply originally because I don't have much insight to offer, other than that rtpengine doesn't support this at all and that RFC 4796 talks about an "a=content" attribute, not "a=alt". Older versions of the ANAT RFC [1] talk about this attribute, but the final RFC [2] doesn't.
No worries, Richard. Thank you for your reply.
