Asking again since this thread ended with no useful answer (at least for my issue).
Got Front-End pool with 2 servers and 1 Edge.
Working features:
- Full client + mobile internally
- Mobile clients externally
- Web clients from internal and external sides
Stucked on:
- External access for full desktop client refusing to connect after asking for domain account name and password.
Current external DNS records (approved by RUCT):
- _sip._tls.<ext.domain.tld> -> sip.<ext.domain.tld>
- sip.<ext.domain.tld> -> Edge IP
- meet/dialin/lyncdiscover.<ext.domain.tld> -> TMG RP IP
MLCA tool says that SIP Server Externall Access field "is empty in the discovery response" and"DNS resolution failed for the external SIP server address retrieved during server discovery. Verify your topology configuration or contact your support team." As result - current configuration doesn't meet minimum requirements for Lync Windows Store app.
I know, that full Lync 2013 Client and Store app have differences, but that logs all I have for now.
So the question is - what I missed for working full Lync 2013 desktop client?
