Assessing Network regarding PSTN Calls via Skype CCE

Hi,

 

in technet are rather specific and detailed network requirements for Skype for Business Onlinehttps://support.office.com/en-us/article/Media-Quality-and-Network-Connectivity-Performance-in-Skype...

 

They seem to be already more strict and specific than for Skype for Business Server 2015. In a nutshell those seem to be 1. provide enough capacity for target workloads 2. No latencies over 150 ms must occur

https://technet.microsoft.com/en-us//library/gg425841.aspx?f=255&MSPPError=-2147217396

 

Consider a scenario with Skype Online + one Cloud Connector Edition for PSTN calls. assuming the following PSTN media call flow

Client internal - CCE Mediation Server in DMZ - Session Border Controller/Gateway -  local pbx

 

So:

What network requirements are there for the PSTN Calls in this setup?

How to make sure to meet those and provide reliable, high quality PSTN Calls?

Tool recommendations?

Hi Manuel,

we do have a tool recommendation and we have also detailed guidance as part of SOF. Please refer to the following two training sessions at https://www.skypeoperationsframework.com/academy?SOFTrainings:

  • Network Readiness
  • Delivering Network Readiness

Hi, thanks, but I already consumed the SOF network assessment materials and the videosessions.

Was hoping to find additional guidance for CCE Scenarios.

Re: Assessing Network regarding PSTN Calls via Skype CCE

Hi Manuel,

since you are looking at the scenario for an internal user doing a call via Cloud Connector Ediion, al media will stay internal on a managed network. On a managed network we expect virtually no packet loss, no jitter and latency only what physics determies based on distance. More information on metrics for managed networks can be found in the "Network Planning, Monitoring, and Troubleshooting with Lync Server" https://www.microsoft.com/en-us/download/details.aspx?id=39084

 

Please let me know if this helps, if not I'm sure we can continue this discussion Smiley Happy

 

Thanks,

thomas
