NOTE: Cloud PBX Call Queue functionality is still in Preview, so final release may have different functionality.
One ongoing challenge with Skype for Business Server Response Group Service has been what has been referred to as the “answer delay”. This is the time between when a Skype for Business user answers a call and the media is flowing and the user can say “Hello” and start speaking.
Cloud PBX Call Queues are not “SfB RGS ported” to Office 365, but have been rewritten by the Microsoft team to optimize the functionality for the cloud. We have done some testing to see what the “answer delay” is on the new Office 365 Call Queues (in Preview at this time). We tested using a site with 100MB Up/5MB Down data pipe.
The “Skype for Business Network Assessment Tool – Results Analyzer” results were:
|Device||Answer to Talk time|
|Polycom VVX 600||5.10 seconds|
|Skype for Business 2016 client + USB Headset||4.26 seconds|
|Lync Phone Edition (Polycom CX600)||5.36 seconds|
From our tests the configuration with the least delay is the Skype for Business client with a USB headset.
One surprise from this test is how close the Lync Phone Edition was to the other devices, which leads me to believe the delay is now a result of the connection between Office 365 and the endpoint device, and not so much a result of the design of Cloud PBX Call Queues.
Since this is still considerable delay users may wonder how to know when they can say “Hello” and my old article about Skype for Business RGS is still relevant, read it here.
