If a party that is placed on hold (e.g., B in the above example) is called by another
party (e.g., D), then the on-hold party receives a call waiting tone instead of the
held tone.
•
While in a Double Hold state, placing the phone on-hook disconnects both calls
(i.e. call transfer is not performed).
•
You can enable the device to handle incoming re-INVITE messages with
"a=sendonly" in the SDP, in the same way as if "a=inactive" is received in the
SDP. This is configured using the SIPHoldBehavior parameter. When enabled, the
device plays a held tone to the Tel phone and responds with a 200 OK containing
"a=recvonly" in the SDP.
