Hi Ashok,

Subscribing on missed-calls and incoming-call-pickup is allowed for the currently logged-in User due to security reasons. It's used to work this way for a long time. I believe there is no difference between Sandbox and Production for this behavior. 

message-store is available for any User with {{ReadMessages}} permission, typically it's available for Admin Users and own extensions. 

Could you please describe the scenario why do you need to get missed-calls notifications, which belong to another extension(s)?

Hi Ashok,

I you can use this workaround solution to detect missed call for any extension under an account. The sample code is in Node JS, but you can implement similar way in other programming languages.

var RC = require('ringcentral')  require('dotenv').load()    var rcsdk = new RC({    server: process.env.SERVER,    appKey: process.env.APP_KEY,    appSecret: process.env.APP_SECRET  })  var users = []  var platform = rcsdk.platform()    login()    function login(){    platform.login({      username: process.env.USERNAME,      password: process.env.PASSWORD    })    .then(function(resp){      removeRegisteredSubscription()      subscribeForNotification()    })    .catch(function(e){      console.log(e)      throw e    })  }    var subcription = rcsdk.createSubscription()  function subscribeForNotification(){    var eventFilter = []    eventFilter.push('/restapi/v1.0/account/~/presence')    subcription.setEventFilters(eventFilter)    .register()    .then(function(resp){        console.log('ready to get account presense')    })    .catch(function(e){      throw e    })  }  subcription.on(subcription.events.notification, function(msg){    var user = {}    user['extensionId'] = msg.body.extensionId    user['telephonyStatus'] = msg.body.telephonyStatus    checkMissedCall(user)  })    function checkMissedCall(user){    var newUser = true    for (var i=0; i<users.length; i++){      if (users[i].extensionId == user.extensionId){        newUser = false        if (users[i].telephonyStatus == "Ringing" && user.telephonyStatus == "CallConnected"){          users[i].telephonyStatus = user.telephonyStatus          console.log("this extensionId " + users[i].extensionId + " has a accepted a call")          break        }        if (user.telephonyStatus == "NoCall" && users[i].telephonyStatus == "Ringing"){          users[i].telephonyStatus = user.telephonyStatus          console.log("this extensionId " + users[i].extensionId + " has a missed call")          break        }        users[i].telephonyStatus = user.telephonyStatus      }    }    if (newUser){      users.push(user)    }  }    function removeRegisteredSubscription() {

    platform.get('/subscription')        .then(function (response) {          var data = response.json();          if (data.records.length > 0){            for(var record of data.records) {              // delete old subscription before creating a new one              platform.delete('/subscription/' + record.id)                .then(function (response) {                  console.log("deleted: " + record.id)                })                .catch(function(e) {                  console.error(e);                  throw e;                });            }          }        })        .catch(function(e) {            console.error(e);            throw e;        });  }  

Hope this helps!
