Call Hold
Call hold provides a service of placing an active call on hold. It enables you to pause activity on an active call so that
you can use the phone for another task, for example, to place or receive another call.
When a call is placed on hold, the phones send an INVITE request with HOLD SDP to request remote parties to stop
sending media and to inform them that they are being held. The phones support two call hold methods, one is RFC
3264 , which sets the “a” (media attribute) in the SDP to sendonly, recvonly or inactive (for example, a=sendonly). The
other is RFC 2543 , which sets the “c” (connection addresses for the media streams) in the SDP to zero (for example,
c=0.0.0.0).
When you place an active call on hold or the call is held by remote parry, a call hold tone or held tone alerts you after a
specific period of time that a call is still on hold or is still held by the remote party. You can configure the call hold tone
and held tone.
If supported by the server, you can also configure a music-on-hold URI.
