Parameter: Early Media Relay and Ring Tone Generation: Connect full-duplex during early-media
From TBwiki
- Connect full-duplex during early-media: Forces full-duplex media on an outgoing call during early media (after call is alerted, before it's answered). This applies only to SIP calls (TDM calls are always connected full-duplex).
- When enabled: RTP and RTCP will be both received and sent toward outgoing call
- When disabled: RTP received from outgoing leg is bridged to the incoming leg, but no RTP or RTCP is sent toward the outgoing call
