The first is how to place outbound calls from a UCMA application that isn’t connected to Lync Server. The second is how to bypass Lync Server for certain calls from a UCMA application that is connected to Lync Server.
For both of these things, you can use an awesome, little-known UCMA class called ConnectionContext. Continue reading “Outbound calls from UCMA without Lync Server” »
