Hi Rattnesh_Pandey,

The internal and external Mcx FQDNs will always be set to the same value, either the internal or external FQDN depending on the state of the ExposedWebUrl parameter.  Mobile clients cannot be allowed to use either service as the Mcx services on Front End servers do not talk to each other and cannot coordinate connection state for a device which might move between an external network (e.g. 4G cellular data) and an internal network (e.g. corporate Wi-Fi).  Thus all mobile clients in an environment must be directed to either the internal web service or the external web service.  In any typical deployment with external Lync connectivity the external Mcx web service will handle all connections and the internal Mcx web service would never be used.

Hi

You can only have one active simple url per SIP domain I believe. Using different URLs even if possible would cause meeting join issues between internal and external participants .

thanks
