Skype for Business with Expressway and CMS

Dear all

Do we have the same Certificate requirement if are using CMS with Expressway if Dial-In from external S4B client ?
as we are using CMS-Core and CMS-Edge ?
because I have move the config solution from
CMS-Edge --CMS-Core
to
Expr-E -- Exp-C -- CMS-Core

- Exp-E is Single NIC with Public IP
- Turn Server using of Expr-E
- wbeRTC via Expr-E to CMS-Core is running well !
- so it seems TURN Server is running
- RMS License exist on the Exp-E ( I think is needed, without License Call was not going trough the Exp-E)

- CMS running SW 2.1.7

- Expressway running X8.9.2


At the moment I have the following Certificate:

  • Exp-E
    • Public CA signed with SAN of Expr-E, (not SAN of CMS-Core include!!!) is that a problem ?
  • EXP-C
    • Internal CA signed (without SAN of CMS-Core)
  • CMS-Core
    • Callbridge official Public CA signed with SAN of Expr-E


Questions:

  • Single NIC running on Exp-E?
  • callbridge config on CMS
    • should I configure the "callbridge edge" to Expressway-E or Expresway-C or let it empty?

- Dial-in from S4B to CMS is ringing but call can not established, after 10 sec disconnect:

call 1: recognised as Lync
2017-05-10 13:45:49.883 Info call 1: incoming encrypted SIP call from "sip:user1@domain.com" to local URI "sip:4321@space-cms.com" (Lync)
2017-05-10 13:45:50.455 Info participant "user1@domain.com" joined space 4a04eb96-3309-4296-8901-9260b77b6a9c (user Spaces)
2017-05-10 13:45:56.201 Info call 1: media framework reporting rx video RTP frequency 0 - fixed up to 90000
2017-05-10 13:46:01.645 Info call 1: ending; remote SIP teardown; ICE negotiation in process - connected for 0:11
2017-05-10 13:46:01.646 Info participant "user1@domain.com" left space 4a04eb96-3309-4296-8901-9260b77b6a9c (user Spaces)

- Dial-Out from CMS to S4B , the same problem

- Eventlogs on the Exp-C / Exp-E

I see the Calls on the Expressway's is going to the right traversal Link,

Any Input or help appreciated.


Best regards
Georg
