I beg to differ.
Technically there is no HOLD request.
All there is is an offer that offers to change a media attribute, from
sendrecv to sendonly or inactive, or from sendonly or recvonly to inactive.
The response may change anything that is permitted to be changed in the
answer, given the offer. So it may not add m-lines, but it can certainly
change media addresses, and within limits may change media formats (codecs).
Thanks,
Paul
