CallRexServiceProxy

CallRexServiceProxy is the WCF client proxy for the CallRex on-demand recording SOAP service. It performs recording lookup, deletion, invalidation, and start/stop/pause/resume recording control, and is the sole consumer of the CallRex ClientServiceClient generated client. It is wrapped by CallRecordingSystem.

Purpose

• Translate IRecordingSystem-style recording operations into calls against the CallRex ClientServiceClient SOAP endpoint, including authentication header injection on every call.
• Map vendor RecordedCallContainer/AttachedDataContainer responses onto the library's CallRecording DTO, computing description, discoverability flags, and call direction.

Context

• Namespace: SAIF.Services.ClientProxies.ThirdParty
• Assembly/package: SAIF.Application.Services.AudioVideo

Public members

Member	Signature	Purpose
(constructor)	public CallRexServiceProxy(string serviceUrl, IEnvironmentService envSvc, ILogService logSvc)	Configures a BasicHttpsBinding with NTLM transport security, constructs the ClientServiceClient, and logs in with fixed vendor credentials.
OnFileTransferCompleted	public FileTransferCompleted OnFileTransferCompleted (delegate event field)	Raised when the underlying vendor client reports a completed file transfer.
OnFileProgressChanged	public FileProgressChanged OnFileProgressChanged (delegate event field)	Raised when the underlying vendor client reports file-transfer progress.
MarkInvalid	public virtual void MarkInvalid(CallRecording recording)	Updates the recording's attached description to prefix "Invalid:" via UpdateAttachedDataByCallLogID (see BR-AV-10).
DeleteRecording	public virtual bool DeleteRecording(Guid recordingId)	Deletes a recording from CallRex, returning whether the call succeeded.
GetAllRecordings	public virtual IEnumerable<CallRecording> GetAllRecordings()	Retrieves and maps all recorded calls.
GetRecordings	public virtual IEnumerable<CallRecording> GetRecordings(Guid userId)	Retrieves and maps all recorded calls for a specific vendor user ID.
GetRecording	public virtual CallRecording GetRecording(Guid recordingId)	Retrieves all recorded calls and filters/maps to the single matching recording.
GetUsers	public virtual IEnumerable<CallUser> GetUsers()	Retrieves and maps all CallRex-registered users.
StartRecording	public virtual void StartRecording(Guid userId)	Starts on-demand recording for a user via StartOnDemandRecording.
StopRecording	public virtual void StopRecording(Guid userId)	Stops on-demand recording for a user via StopOnDemandRecording.
PauseRecording	public virtual void PauseRecording(Guid userId)	Pauses on-demand recording for a user via PauseOnDemandRecording.
ResumeRecording	public virtual void ResumeRecording(Guid userId)	Resumes a paused on-demand recording via ResumeOnDemandRecording.
Dispose	public void Dispose() (from IDisposable)	Closes the underlying ClientServiceClient WCF channel.

Behavioral notes

• Authenticates using a hardcoded username ("AI") and password ("AudioImporter") supplied as SOAP message headers on every service-affecting call via AuthorizeClientServiceCall (see dependencies.md for the associated hardcoded-credential note).
• GetRecording(Guid) retrieves the entire recorded-call list and filters client-side rather than calling a single-recording vendor endpoint — an explicit todo comment in source notes this as a placeholder pending a dedicated vendor call.
• Recording mapping (GetRecording(RecordedCallContainer)) computes CallDirection via a private GetCallDirection helper (dialed number takes precedence over caller-ID number — see RecordingCallDirection), and strips the literal word "test" from the vendor description while separately checking for it to set IsProductionRecording (see BR-AV-11).
• Most public members are virtual, allowing test doubles to override behavior without a formal interface.*

Constraints and usage notes

• All operational methods that call the vendor service inject authentication headers via AuthorizeClientServiceCall; direct calls to the underlying ClientServiceClient bypassing this proxy would fail authentication.
• Instances should be disposed after use to close the underlying WCF channel.

Note: Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts.
