On the front end server, the IM Conferencing IP Address is set to: All, port 5062.
The certificate is set to "Enable all purposes for this certificate." (Only one is in use, issued by an internal CA).
Trace logging shows the following errors from the server:

$$end_record
It seems to boil down to one of the following, there is a missing DNS SRV record for the IM Conferencing service, but I do not see any reference in the documentation.
The server is unable to create a socket for the IM Conference.
Or there is a component to the IM Conferencing service that is not listening on TCP/5062 that should be, but I can not find any errors, or failed services.
I have tried telneting to the server on the 5062 port, and there is no response.
Validation and Best Practice scans do not reveal anything that is not configured, i.e., we are not using external conferencing, and the routing plans/normalization patterns must match Cisco Call manager.
Thanks in advance for any help!
Thanks!
