SIP Features

Switching Between Early Media and Local Ringing

Previously, the phone generated a local ring tone when receiving a 180 response
unless early media was being played, regardless of SDP. The local ring tone stopped
when the first RTP packet was received in the early session. The local ring tone did not
resume when it received subsequent 180 responses, even though early media was
not being received.
In Release 2.6, the phone supports switching between early media and local ring tone.
Upon receiving a 180 response, the phone now generates a local ring tone unless it is
receiving an early media flow. If the phone receives any subsequent 180 responses, it
regenerates the local ring tone unless it is receiving early media flow.
Added "Call-Info" Header to 200ok Responses for Shared Call
Appearance (SCA) Lines
In previous IP phone software releases, a "Call-Info" header was only added to the
requests generated by the phone for Shared Call Appearance (SCA) lines. In Release
2.6, a "Call-Info" header is now also included in the 200ok response to an INVITE, RE-
INVITE, and UPDATE messages for SCA lines. No configuration is required for this fea-
ture.
