4.15.4 Configuring Early Media

Early media refers to audio and video that is exchanged before a call is accepted by the

recipient. Early media generated by the caller includes voice commands or dual-tone multi

frequency (DTMF) tones to activate interactive voice response (IVR) systems. Early media

generated by the call recipient include ringback tones, announcements, and requests for

input.

Enhanced early media support in Microsoft Lync 2013 enables a caller to hear a ringback

tone generated by the call recipient’s mobile phone. This is also the case in team-call

scenarios, where a call is routed to two team members, one of whom has configured

simultaneous ringing for his or her mobile phone.

According to Microsoft Lync 2013 requirements, Enhanced gateway must send a SIP 183

with SDP immediately after it receives an INVITE. The RTP packets however, will not be

sent until the Enhanced gateway receives an ISDN Progress, Alerting and Progress

Indicator or Connect message. For example, if the Enhanced gateway receives ISDN

Progress, it starts sending RTP packets according to initial negotiation; however, there is

no need to re-send the 183 response.

You may need to configure the Enhanced gateway's early media feature to support the

Microsoft Lync 2013 enhanced early media feature.
