Caller Privacy Support

 

The

supports caller privacy dynamically based on privacy header.

The special URI anonymous@host; user=phone in From header field denotes an anonymous user whose presentation is restricted. Microsoft Lync 2010 Mediation Server uses the alias name of user in the FROM header (instead of phone number) and without user=phone parameter, to hide a phone number. The

 identifies these two cases as presentation restriction. When presentation is restricted, if the SIP trunk has a default number configured, the  uses that number in user part of FROM header while sending the egress message.

The 

supports caller privacy for incoming and outgoing calls as described below:

• For incoming calls from the SIP Trunk that the Enterprise

• For outgoing calls from the Mediation Server, if the From URI in the SIP INVITE sent to the Enterprise
  Unable to show "metadata-from": No such page "_space_variables"
   denotes an anonymous user or is a SIP URI with an alias name, the
  Unable to show "metadata-from": No such page "_space_variables"
   excludes or sets default value to Calling Party Number sent to the SIP Trunk.
