Dead air calls on random numbers

Hi, 
We are experiencing random dead air calls to a specific entry(Invalid/no input) on a call flow. We have a flow which has CED which contains around 6 cases excluding invalid input/Timeout flow in ICM Script. Of those CED 5 and Invalid input/timeout will make a transfer to a Hunt group for same extension. 
So if any body press 5/invalid input they will get transferred to a same extension which is configured as hunt group in cucm. The challenge here is we are getting a dead air calls randomly only to the invalid entry not other entry which is doing the same call treatment with same extension.
Any advise to fix this would be much helpfull..

    Hello stufaro, let's solve this mystery! It sounds like someone has activated call forwarding on their phone and have accidentally made the calls route to your number instead of to another line if they input the number incorrectly. I'm sorry to say that only the other user can deactivate the call forwarding from their phone. The next best solution would indeed be to change your number if the calls are frequent.

  • Dead Air Phone Calls with Blue Tooth and Speaker function?

    My experience with Note 4 speaker function and blue tooth headsets is they malfunction as often as they work properly during phone calls.  When the speaker or blue tooth is activated during a call there is dead air between myself and the other party.  I am on my fourth Note 4 in a month due to this problem, that is I bought a new phone and Verizon has sent me three replacements in an effort to fix the issue.  Each phone has malfunctioned in exactly the same way.  Verizon and Samsung are unable to discuss this with me other than to go through all the diagnostic steps every time I call to ask for help.  I am at the point of either living with the problem or changing phones altogether.
    Something I find amazing is when I talk to Verizon or Samsung they say this is not a reported issue.  Maybe I am the only person who had this experience.  Maybe I got the only four Note 4's (in a row) that malfunction like this.  Maybe. 
    This leaves holding the phone to my ear, which is rather old school and does not work with my state's driving laws.   Any fixes or reality checks are welcome.    

        SteveQuintanaRealEstate,
    I'm saddened to hear that you've had such an experience with your Galaxy Note 4's.  It sounds like Verizon has done everything possible to assist with your Samsung devices.  Have you noticed any patterns to when the malfunctions occur?

  • My iphone 4 is calling random numbers

    My iPhone 4 is dialling random numbers on its own.
    I looked down at my phone when i thought it was locked + it was dialling this random number and then stopped.
    The number appeared in my recent calls list and it is a completely random number; not from my contacts or even similar to any unsaved numbers in my recent calls.
    In addition, this follows a couple of recent cases of possible pocket dialling of my contacts. Which I thought would be impossible cause i keep my phone locked with a passcode.
    How did this happen?

    Okay, I have no idea how to delete this, but if this ever happens to someone else, don't share your apple ID with younger siblings. Turns out I was watching their conversations... bit creepy lol

  • Cannot make calls or receive calls. Good network coverage. All I get is static or dead air. I've tried restoring to factory settings. Rebooting ect. No luck. Any suggestions?

    i Am using an iPhone 6 plus. just bought it 10 days ago. I am unable to make or recieve calls. I either get static or dead air, the person on the other end cannot hear me or they only hear static.  I have tried hard rebooting the phone which did not work. I tried restoring the phone to factory settings no luck. I am out of ideas on how to fix the issue. I have excellent network coverage and am connected to wifi. Please help.

  • CWMS 2.0MR7 intermittent dead air on call-in and call-back for internal and external users

    Hello,
    I have got a new install of CWMS 2.0MR7 800 users non HA system. During initial testing we noticed that when we call-in or call-back there was a dead air even though the call is connected we don't hear welcome to WebEx....when we hang up and call again it works fine and we hear welcome to WebEx so the issue is intermittent. CUCM version is 8.6
    Can someone please advise how do we go about troubleshooting something like this when the issue is so intermittent?
    Thanks

    Hi,
    Please check the following:
    1. Please check if you are on supported hardware and that no co-resident VMs exist:

  • Hi, I have an iPhone 4 which rings people when it is locked, whether or not in my pocket.  I always lock it when not using it.  Can anyone help? It is calling random numbers, not the last person or anyone even recently called on my recents list. Thanks

    Pay no attention to iinami, the amount of replies to people saying their handsets must have been jailbroken everytime iTunes throws out an error is tremendous. (Clearly you don't need to have any real knowledge to get to level 3 on these forums, let's hope apple's geniuses know a lot more than some of their customers.)
    http://support.apple.com/kb/TS3694
    Solution below.
    Error 9
    This error occurs when the device unexpectedly loses its USB connection with iTunes. This can occur if the device is manually disconnected during the restore process. This issue can be resolved by performing USB troubleshooting, using a different USB dock-connector cable, trying another USB port, restoring on another computer, or by eliminating conflicts from third-party security software.

    Have you tried the standard fixes:
    - Reset
    Reset iPod touch:  Press and hold the On/Off Sleep/Wake button and the Home
    button at the same time for at least ten seconds, until the Apple logo appears.
    - Restoring from backup
    - Restoring to factory defaults/new iPod
    Are you using the headphone/mic?  If so sometimes sweat/moisture in the controls can make the iPod do strange things.
    What number are you looking for?

  • Agent Reserverd caller hears Dead air after CUCM upgraded to 10.5.2.11005-1

     After a recent upgrade on my SME head end cluster from CUCM 9.1.2.11900-12 to 10.5.2.11005-1 I have been having an issue with my call center agents on a leaf cluster running 7.1.5.35900-7 (Cluster 1).  This is both enterprise and express agents.
     The call comes in on a leaf cluster running CUCM 9.1.2.11900-12 (Cluster 2)
     Then goes to a head end SME CUCM 10.5.2.11005-1 cluster via a SIP trunk
     Then the calls goes to a CUCM 7.1.5.35900-7 (Cluster 1) leaf cluster via an Inter-Cluster Trunk
     The call center agents get put in reserved status but never get the call.
     The callers just hear dead air.
     The only changes is the upgrade to the head end cluster to 10.5.2.11005-1.
     If I add a dial peer on the PSTN gateway CUCM 9.1.2.11900-12 (Cluster 2) leaf cluster so the call goes from gateway to CUCM 7.1.5.35900-7 (Cluster 1) the agent does not have any issues.
     My initial thought is a possible change on the trunks from Cluster 2 to SME or SME to Cluster 1.
     Anyone have any thoughts on this?

    Not sure if this is related since this was a while back and it was on version 8.5 that I noticed this. If I recall there is was an issue with the SME cluster talking to the leaf cluster. If the SIP Trunk was talking to a specific node in the cluster, the intra cluster signaling had some problems. i.e. if you had Sub-A and Sub-B and if the SME Cluster sent the invite to Sub-A while the phone sat on Sub-B, the call wouldn't go through. It had to do with making sure that the Call Manager Group assigned to the device pool that was assigned to trunk had all CCM nodes in the cluster added to it. This became an irritation when I was working on it because we had more than 3 CCM Subscribers and there is a limit of 3 CCM nodes per Call Manager group and we had 4 CCM subs in the cluster which means we would never be able to send calls to a phone in the leaf cluster registered to the 4th node that wasn't part of the CCM Group for the device pool used by the SIP trunk between the Leaf and SME cluster. 
    You are dealing with 10.5 and you also mention that this was working prior, so I am not sure if this is the same, but I would certainly play around with the CMG for the device pool of the trunk and the CM that the phone registers to. 

  • Bips and random numbers while making calls

    When talking on the phone (iPhone 4 with iOS 6) I get beeping noises and random numbers generated at the top of the screen. Has anyone else encountered this? HELP!

    I'm having the same issue and it has just started after the recent OS update. I have a 5S. Hope there is a fix, as it is terribly annoying.

  • Callers are intermittently getting dead air then disconnected when arriving on the CVP !!

    Callers are intermittently getting dead air then disconnected when arriving on the CVP ,
    Is the problem with Voice Gateway (Ingress)/Gateway Device issue in CVP server ??
    Thanks !!!
    Shridhar Reddy

    First thing to check would be Router Log Viewer to see if you have missed a Dialed Number - Call Type association on one of your CVP PIMs. If the gateway sends the call to a Proxy which then distributes to Call Servers, and not all the PIM Dialed Numbers are associated with the Call Type that runs your Scheduled Script, some will fail will all others will work.
    You need to provide more information for us to have a stab at a remedy.

  • Array of unique random numbers - help?

    basically, i'm trying to create a BINGO card.
    i stared learning Java a week ago and am finding it easy to learn and use....at least so far.
    my instructor gave me the assignment to created a BINGO card. so i used the system.out.format command to make 5 tab fields, 8 spaces each ("%8s %8s %8s %8s %8s", "B", "I", "N", "G", "O"). although the assignment only wanted me to think numbers out of thin air, just to use as examples, i went above and beyond with the idea to make a BINGO card generator that could actually function.
    then i started the random number sequences, using the Math.random() command. all told, there are 24 of these in the program, one for each number on a bingo card. the field in the middle is the FREE space, so it has no Math.random command.
    in BINGO, each letter (one of my five tab fields) can have a number in ranges of 15. B is 1 to 15, I is 16 to 30, etc. it looks similar to this:
    B I N G O
    9 19 39 57 66
    3 28 32 51 74
    3 29 FREE 46 70
    14 28 43 55 67
    9 24 35 59 62
    as you can tell, i'm having trouble with actually making unique random numbers so that none repeat.
    is there a command or string or something to help me accomplish this?

    The best way I've come up with is to use an object to store the numbers that implements Collection--like ArrayList...
    Then you load it with the range of numbers that you want and call, shuffle() on the object, that will randomize your range of numbers and then you can choose the quantity you want from the storage object. So let's say you need 25 number in the range of 1 to 100:
    Add the numbers (you have to use classes so I would do Integers) 1 to 100;
    call shuffle()
    pull back the first 25 numbers
    This will guarantee that each number is distinct and in a random order.
    If you need multiple sheets populated, you can just call shuffle() between population of each sheet.
    package Junk;
    import java.util.ArrayList;
    import java.util.Collections;
    class Junk{
      private ArrayList<Integer> l;
      Junk(){
        l = new ArrayList<Integer>();
      public void loadList(int s, int e){
        for(int i=s; i<=e; i++){
          l.add(new Integer(i));
      public void randomizeList(){
        Collections.shuffle(l);
      public void printList5(){
        for(int i=0; i<5; i++){
          System.out.println(l.get(i));
      public static void main(String[] args){
        Junk j = new Junk();
        j.loadList(10,99);
        j.randomizeList();
        j.printList5();
        System.out.println();
        j.randomizeList();
        j.printList5();
    }

  • I am trying to generate an array of 30 random numbers. after every 5 readings a new vi should open and tell the user that 5 readings has been completed. and again carry on with the generation of array.

    since i do not have a transducer now, i am currently generating an array of 30 random numbers. after every 5 readings a warning should be given to the user that 5 readngs are complete. this cycle should repeat. the array size is 30.
    please help me out,  waiting for reply asap.
    once i have the transducer, i will be taking 30 analog samples and then after every 5 smaples that wraning will be displaye din a new VI
    Solved!
    Go to Solution.

    Use a while loop with a time delay representing your sampling period.
    Use the count terminal to check if equals 4, so 4th iteration=5th sample.
    Use a case structure. The true case will only be executed on the 4th iteration.
    In the true case place a subVI  with your desired message in the front panel. Go to the VI properties window and set "open front panel when called".
    The closing condition of the warnign is not giving in your description.
    Consider that rather than usign a subvi for this, you could use the "One/Two/Three button dialog" or "display message" vis at the "dialog and user interface" pallete.
    Please give it a try and send your own VI. Do not expect us to provide a working solution.

  • I need help with this program ( Calculating Pi using random numbers)

    hi
    please understand that I am not trying to ask anymore to do this hw for me. I am new to java and working on the assignment. below is the specification of this program:
    Calculate PI using Random Numbers
    In geometry the ratio of the circumference of a circle to its diameter is known as �. The value of � can be estimated from an infinite series of the form:
    � / 4 = 1 - (1/3) + (1/5) - (1/7) + (1/9) - (1/11) + ...
    There is another novel approach to calculate �. Imagine that you have a dart board that is 2 units square. It inscribes a circle of unit radius. The center of the circle coincides with the center of the square. Now imagine that you throw darts at that dart board randomly. Then the ratio of the number of darts that fall within the circle to the total number of darts thrown is the same as the ratio of the area of the circle to the area of the square dart board. The area of a circle with unit radius is just � square unit. The area of the dart board is 4 square units. The ratio of the area of the circle to the area of the square is � / 4.
    To simuluate the throwing of darts we will use a random number generator. The Math class has a random() method that can be used. This method returns random numbers between 0.0 (inclusive) to 1.0 (exclusive). There is an even better random number generator that is provided the Random class. We will first create a Random object called randomGen. This random number generator needs a seed to get started. We will read the time from the System clock and use that as our seed.
    Random randomGen = new Random ( System.currentTimeMillis() );
    Imagine that the square dart board has a coordinate system attached to it. The upper right corner has coordinates ( 1.0, 1.0) and the lower left corner has coordinates ( -1.0, -1.0 ). It has sides that are 2 units long and its center (as well as the center of the inscribed circle) is at the origin.
    A random point inside the dart board can be specified by its x and y coordinates. These values are generated using the random number generator. There is a method nextDouble() that will return a double between 0.0 (inclusive) and 1.0 (exclusive). But we need random numbers between -1.0 and +1.0. The way we achieve that is:
    double xPos = (randomGen.nextDouble()) * 2 - 1.0;
    double yPos = (randomGen.nextDouble()) * 2 - 1.0;
    To determine if a point is inside the circle its distance from the center of the circle must be less than the radius of the circle. The distance of a point with coordinates ( xPos, yPos ) from the center is Math.sqrt ( xPos * xPos + yPos * yPos ). The radius of the circle is 1 unit.
    The class that you will be writing will be called CalculatePI. It will have the following structure:
    import java.util.*;
    public class CalculatePI
    public static boolean isInside ( double xPos, double yPos )
    public static double computePI ( int numThrows )
    public static void main ( String[] args )
    In your method main() you want to experiment and see if the accuracy of PI increases with the number of throws on the dartboard. You will compare your result with the value given by Math.PI. The quantity Difference in the output is your calculated value of PI minus Math.PI. Use the following number of throws to run your experiment - 100, 1000, 10,000, and 100,000. You will call the method computePI() with these numbers as input parameters. Your output will be of the following form:
    Computation of PI using Random Numbers
    Number of throws = 100, Computed PI = ..., Difference = ...
    Number of throws = 1000, Computed PI = ..., Difference = ...
    Number of throws = 10000, Computed PI = ..., Difference = ...
    Number of throws = 100000, Computed PI = ..., Difference = ...
    * Difference = Computed PI - Math.PI
    In the method computePI() you will simulate the throw of a dart by generating random numbers for the x and y coordinates. You will call the method isInside() to determine if the point is inside the circle or not. This you will do as many times as specified by the number of throws. You will keep a count of the number of times a dart landed inside the circle. That figure divided by the total number of throws is the ratio � / 4. The method computePI() will return the computed value of PI.
    and below is what i have so far:
    import java.util.*;
    public class CalculatePI
      public static boolean isInside ( double xPos, double yPos )
         double distance = Math.sqrt( xPos * xPos + yPos * yPos );        
      public static double computePI ( int numThrows )
        Random randomGen = new Random ( System.currentTimeMillis() );
        double xPos = (randomGen.nextDouble()) * 2 - 1.0;
        double yPos = (randomGen.nextDouble()) * 2 - 1.0;
        int hits = 0;
        int darts = 0;
        int i = 0;
        int areaSquare = 4 ;
        while (i <= numThrows)
            if (distance< 1)
                hits = hits + 1;
            if (distance <= areaSquare)
                darts = darts + 1;
            double PI = 4 * ( hits / darts );       
            i = i+1;
      public static void main ( String[] args )
        Scanner sc = new Scanner (System.in);
        System.out.print ("Enter number of throws:");
        int numThrows = sc.nextInt();
        double Difference = PI - Math.PI;
        System.out.println ("Number of throws = " + numThrows + ", Computed PI = " + PI + ", Difference = " + difference );       
    }when I tried to compile it says "cannot find variable 'distance' " in the while loop. but i thought i already declare that variable in the above method. Please give me some ideas to solve this problem and please check my program to see if there is any other mistakes.
    Thanks a lot.

    You've declared a local variable, distance, in the method isInside(). The scope of this variable is limited to the method in which it is declared. There is no declaration for distance in computePI() and that is why the compiler gives you an error.
    I won't check your entire program but I did notice that isInside() is declared to be a boolean method but doesn't return anything, let alone a boolean value. In fact, it doesn't even compute a boolean value.

  • Random numbers in arrays

    i have been faced with a new problem, i have to generate a random number (between 0-63) of random numbers (between 0-63).
    Can i do this all in one array to randomly generate an array containing the random number of elementnts and set each of the elemnt to a random value.
    Random x = new Random();
    int j= x.nextInt(63);
    String [j] numbers;
    Random q = new Random();
    for(j=0, j<=numbers.length, j++)
       int f= q.nextInt(63);
      numbers[j] =f;
    } I had an idea of doing something like the code above can any see a better way to do it.

    I am getting this error
    java.lang.ArrayIndexOutOfBoundsException: 15
    from
    numbers[z] = rng.nextInt(63);i think this is because i am randomly calling the method, so it runs through it once but the second time it flags up the error.
    void Randm()
                         Random rng = new java.security.SecureRandom();
                    int o = rng.nextInt(63);//I hope you know this is zero to 63 exclusive, i.e., it can't return 63
                    int [] numbers = new int[o];
                    for(int z = 0 ; z <= numbers.length ; z++)
                        numbers[z] = rng.nextInt(63);// again, this will not return 63
                        System.out.println("ran gen "+numbers[z]);
    }I think it may be the way i am declaring the array, can anyone shed some light on the situation.

    Hi everyone,

    For everyone's info, there is one on the FSHARE CD that I contributed.
    It is called 'ransort' I believe. It will randomly generate as many
    random numbers as desired, and then provide another option to sort
    them. We no longer need the random generation part in V2, but the
    QuickSort routine is very fast, and worth taking a look at.
    Send me a note if you don't have access to FSHARE, and would prefer
    an export over the net.
