As a swag for how to encode this in actual headers, how about:
INVITE ...
Exchange-Events: dtmf;sendrecv, foo;sendonly;
bar;recvonly; xyzzy;sendrecv
200 OK
Exchange-Events: dtmf;recvonly, foo;recvonly;
bar:sendonly; xyzzy:inactive
It's more concise to have:
INVITE ...
Send-Events: dtmf, foo, xyzzy
Recv-Events: dtmf, bar, xyzzy
200 OK ...
Send-Events: bar
Recv-Events: dtmf, foo
ACK ...
Send-Events: dtmf, foo
Recv Events: bar
Do we need to encode in 200 OK that xyyyz was offered and rejected,
or is just not including it in the 200 OK enough?
I think that if you offer to send it, and I don't offer to receive
it, then we know we aren't using it.
