Call to Exchange UM subscriber fails

We have an SBA xxx  then gives an error 500 when we call to Exchange UM subscriber in hybrid Office 365/OnPrem deployment.

15000; reason="Unable to read the user properties publication for the user or contact object."; source="xxx"; appName="ExumRouting"

The solutuon/workaround is to re-create or move contact:

move-CsExUmContact -Identity sip:voicemailxxx@xxx -Target zzz

where ZZZ is hub frontend pool.

To filter out undesirable IP do not use !=

but rather

! ( ip.addr == )

Poylcom VVX UC software and lyncdiscoverinternal

Hello, small note for those who is trying to adapt lyncdiscoverinternal to point to external Reverse Proxy in order to find a good ballance for SFB mobile users.  Mobile phones do not have corporate CA root certificates installed by default.

Apparently Polycom VVX UC software  require that lyncdiscoverinternal point to internal IP, if not it will product a very "descriptive" error:

SSL_get_error Error code=5,rc(0)

The workaround is to disable lync autodiscover and point directly to an internal host:



or in the phone advanced menu in sign-in dialog.

or change lyncdiscoverinternal to point back home.

It looks like this is a new situation, as it seems older versions worked ok.
