Problem Real Connect with SfB 2015 onprem and Cloud Relay

I was trying to implement the RealConnect Hybrid Service for an Skype For Business 2015 ONPREM (no sfb hybrid enanled)  customer. I followed the instructions on the Polycom site

https://cloud-relay-docs.plcm.vc/docs/prereqs, https://rc-docs.plcm.vc/docs/hybrid/prereqs

 

Cloud Relay registration was successful  

 

Current situation/problem:

--We are able to call xxxx@h.plcm.vc however after you enter the Conference Id the message “conference ID invalid” is played. If the Online Sip URI is called including the conference ID (xxx.yyy@h.plcm.vc) the call is not working at all.

 

I did the following to figure out the issue:

  • Check firewall (Customer has a Firewall between Cloud Relay and SfB Pool – allow Port 5061)
  • Installed Application Certificate with and without Cert Chain
  • Check SfB Event Logs (no Error or Warning when we tried to join conference)
  • Trace Sip Stack on SfB Front End Server (no Sip Message from Cloud Relay to SfB Pool when we tried to join the conference)

 

Is there a way to trace a call on the cloud relay itself or enable an advanced logging mode?
