Call Hold
Call hold provides a service of placing an active call on hold. When a call is placed on hold, the
Skype for Business 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. Skype for Business phones
support two call hold methods, one is RFC 3264, which sets the “a” (media attribute) in the SDP
to sendonly, recvonly or inactive (e.g., a=sendonly). The other is RFC 2543, which sets the “c”
(connection addresses for the media streams) in the SDP to zero (e.g., c=0.0.0.0). Call hold tone
allows Skype for Business phones to play a warning tone at regular intervals when there is a call
on hold. The warning tone is played through the speakerphone.
