Description

INVITE Requests without SDP should not change the state of the SDP. However, some servers can not handle this and need a sendrecv in the response whatever the previous state was. If on, the phone sends sendrecv in the response for INVITE Requests with no SDP.

If the value is switched to <hold>, the INVITE invite is still answered with sendrecv. What differs is that a holding state is automatically left and changed to connected, after receiving the ACK with sendrecv.
