Selective Call Routing Guidelines

Review the following guidelines before configuring Selective Call Routing (SCR).

• All features defined for an extension function when SCR sends a call to that extension. For example, if an account is part of a Pickup group, and you set up an SCR rule routing certain calls to that extension, those calls are sent to all extensions in the Pickup group.
  When an SCR rule routes calls away from an account, any settings for Twinning or Monitor groups defined for that account are not applied.
• The number of times a call rings is determined by whatever destination (your account, all intermediate destinations and the final destination) has the least number of rings. For example, if one of your intermediate destinations sends the call to My Voicemail after two rings, the call goes to voicemail after only two rings, even if you set SCR to ring your intermediate destinations five times.
• Every extension is autonomous. Once a call is sent to one of your intermediate destinations, the configuration for that extension takes over. If that extension sends the call immediately to voicemail, the call goes directly to the extension’s voicemail, even if you set SCR to ring all your other intermediate destinations five times. In this example, the other intermediate destinations may not ring at all.
• SCR prevents calls from looping. If your SCR setting sends a call to an intermediate destination, and that intermediate destination includes your extension as part of its SCR settings, the call is not sent back to you.
• SCR rules do not apply to calls that are received as part of a Broadcast group, Hunt group, or Rollover group (see Call Groups for more information about group call options).
• Calls routed by SCR rules to accounts (your account and all intermediate and final destination accounts) that are the primary account for Twinning or Monitor groups, or are part of a Pickup group, are processed according to the normal rules for those features. For example, if you are member of a Pickup group and an SCR rule sends a call to your extension, all other members of the group receive a notification.
• When a subscriber's SCR rule sends a call to a Call Group, the normal rules for that Call Group apply—the first phone to pick up answers the call and stops the other phones ringing or being notified.
• When your intermediate destination activates DND—either when it is active or pressed during ringing (Deflect Call)—the call leg is dropped and DND is not invoked.
• SCR rules are applied based on their priority. If you want a rule applied, make sure it is not superseded by a higher priority rule. For example, if the highest priority rule rejects all calls, then no other SCR rules are applied.
• A rule must be active to be applied. Inactive rules are ignored even if they have a higher priority than active rules.
• When a subscriber has Twinning activated and adds an SCR rule with an intermediate target that is the same as the twinning target, an inbound call that is routed by the SCR rule may reach the subscriber's twinning target's coverage, for example, mobile voicemail.
