Session Initiation Protocol (SIP)

5.1.4.6 6xx Responses - Global Failure

Response		Supported	Notes

600 Busy Everywhere		No

603	Decline	Yes

604 Does Not Exist Anywhere		No

606	Not Acceptable	No

5.1.5 Hold Implementation

The phone supports both currently accepted means of signaling hold. The first method, no longer recommended due in part to the RTCP problems associated with it, is to set the “c” destination addresses for the media streams in the SDP to zero, for example, c=0.0.0.0. The second, and preferred, method is to signal the media directions with the “a” SDP media attributes sendonly, recvonly, inactive or sendrecv. The hold signaling method used by the phone is configurable (for more information, refer to 4.6.1.1.4 SIP <SIP/> on page 88) but both methods are supported when signaled by the remote end point.

5.1.6 Reliability of Provisional Responses

The phone fully supports RFC 3262 - Reliability of Provisional Responses.

5.1.7 Transfer

The phone supports transfer using the REFER method specified in draft-ietf-sip-cc- transfer-05 and RFC 3515.

5.1.8 Third Party Call Control

The phone supports the delayed media negotiations (INVITE without SDP) associated with third party call control applications.
