#Skype4B: Call via work (Part II)


Part I of this blog post covers introduction of Call via work, differentiate remote call control and describe how does CvW work etc. Part II will cover different scenarios of call via work which takes place.

Outbound routing scenario has been covered in Part I. Now, let me describe inbound scenarios.

Skype for Business Server and PBX can be configured in two different ways for incoming traffic:

  1. Skype first in line
  2. PBX first in line

Case 1: User experience when external PSTN user makes an inbound call:

In this scenario, Skype First offers all the features such as Skype toast, missed call alert and voicemail while PBX first only offers voicemail.

Scenario 1: Skype first in line scenario for inbound PSTN call:

User Experience:

  1. PSTN user makes a call
  2. Skype for Business Server receives call
  3. User A client endpoints is alerted
  4. Since User A is enabled for CvW and Simulring, a ms-SkipRnl header is used to force a call out to user A desk phone

Scenario 2: PBX first in line scenario for inbound PSTN call:

User Experience:

  1. PSTN user makes a call
  2. PBX receives call
  3. Since User A has PBX desk phone, therefore user desk phone rings

Case 2: User experience when internal user makes an inbound call:

In this scenario, Skype for Business user (as a first party) offers all the features such as Skype toast, missed call alert and voicemail while PBX desk phone (as a first party) offers voicemail.

Scenario 1: Skype for business user scenario for inbound PSTN call:

User Experience:

  1. User B makes a call to User A from SfB Client
  2. Skype for Business Server receives call
  3. User A client endpoints is alerted
  4. Since User A is enabled for CvW and Simulring, a ms-SkipRnl header is used to force a call out to user A desk phone

Scenario 2: PBX user scenario for inbound PSTN call:

User Experience:

  1. User B makes a call from PSTN desk phone
  2. PBX receives call
  3. Since User A has PBX desk phone, therefore user desk phone rings

I hope, this post gives you clarification about inbound scenarios of CvW. If you have any comments or queries, please write in comments box. I’ll be happy to hear from you and resolve all your queries.
