c# - Lync Client SDK PSTN Calling -

i using lync client sdk 2013, communicate skype business through c# program.

however, cannot find reference in sdk documentation on how make pstn call using sdk.

is possible @ all? short c# code example useful.

you use "tel:" uri want number want dial instead of sip uri. number use depends on dial plan setup of lync server. if want avoid dial plan problems, stick e164 formatted numbers , work number on lync server anywhere.

dialing lync client same normal sip uri except use tel formatted uri instead:

    var participanturi = new list<string> { "tel:+6491234567" };     var automation = lyncclient.getautomation();     automation.beginstartconversation(automationmodalities.audio, participanturi, null, ar =>         {             automation.endstartconversation(ar);         }, null); 

note: there no error checking , beginstartconversation / endstartconversation calling can done in many different ways / styles.
