HI All,

When try to call UM Auto attendent calls get failed, the users is enabled for Lync enterprise voice, i am wondering what should were should i enable SIPSTACK logs.

should it be on Client where UM is tranfeering the all.

Front end server  or Mediation Server,

I should check on PSTN gateway.

just to clearify I have deployed all the roles of Lync 2013 with UM and PSTN gateway.

Thanks &  Regards

HI Kamal

 Can you call the AutoAttendant URI from an internal lync client check if it working.
