The client SHOULD NOT repeat the request. 405 Method not allowed. The primitive is not supported. 406 Message out of sequence. 420 Intended target of the request is for a Control Package that is not valid for the current session. 421 Recipient does not wish to re-negotiate Control Packages at this moment in time. 422 Recipient does not support any Control Packages listed in the SYNC message. 423 Recipient has an existing transaction with the same transaction ID. 481 The 481 response indicates that the transaction of the request does not exist. In response to a SYNC request, it indicates that the corresponding SIP INVITE dialog usage does not exist. 500 The 500 response indicates that the recipient does not understand the request.

MEDIACTRL Interactive Voice Response Control Package Status Codes Standards Action 200 OK Request has succeeded. 400 Syntax error Request is syntactically invalid: it is not valid with respect to the XML schema or it violates a co-occurrence constraint for a request element. 405 dialogid already exists Request uses a dialogid identifier for a new dialog that is already used by another dialog on the MS. 406 dialogid does not exist Request uses a dialogid identifier for a dialog that does not exist on the MS. 407 connectionid does not exist Request uses a connectionid identifier for a connection that does not exist on the MS. 408 conferenceid does not exist Request uses a conferenceid identifier for a conference that does not exist on the MS. 409 Resource cannot be retrieved Request uses a URI to reference an external resource (e.g. dialog, media or grammar) that cannot be retrieved within the timeout interval 410 Dialog execution canceled Request to prepare or start a dialog that has been terminated by a <dialogterminate> 411 Incompatible stream configuration Request specifies a media stream configuration that is in conflict with itself, or the connection or conference capabilities. 412 Media stream not available Request specifies an operation for which a media stream is not available; for example, playing a video media resource on a connection or conference without video streams. 413 Control keys with same value The request contains a <control> element where some keys have the same value. 419 Other execution error Requested operation cannot be executed by the MS. 420 Unsupported URI scheme Request specifies a URI whose scheme is not supported by the MS. 421 Unsupported dialog language Request references an external dialog language not supported by the MS. 422 Unsupported playback format Request references a media resource for playback whose format is not supported by the MS. 423 Unsupported record format Request references a media resource for recording whose format is not supported by the MS. 424 Unsupported grammar format Request references a grammar whose format is not supported by the MS. 425 Unsupported variable configuration Request contains a prompt <variable> element not supported by the MS. 426 Unsupported DTMF configuration Request contains a prompt <dtmf> element not supported by the MS. 427 Unsupported parameter Request contains a <param> element not supported by the MS. 428 Unsupported media stream configuration Request contains a <stream> element whose configuration is not supported by the MS. 429 Unsupported playback configuration Request contains a <prompt> element that the MS is unable to play on the available output media streams. 430 Unsupported record configuration Request contains a <record> element that the MS is unable to record with on the available input media streams. 431 Unsupported foreign namespace attribute or element The request contains attributes or elements from another namespace that the MS does not support. 432 Unsupported multiple dialog capability The request tries to start another dialog on the same conference or connection where a dialog is already running. 433 Unsupported collect and record capability The request contains <collect> and <record> elements and the MS does not support these operations simultaneously. 434 Unsupported VAD capability The request contains a <record> element where Voice Activity Detection (VAD) is required, but the MS does not support VAD. 435 Unsupported parallel playback The request contains a prompt <par> element whose configuration is not supported by the MS. 439 Other unsupported capability Request requires another capability not supported by the MS.
