Interrupting a Call

Quick possibility question.
I have integrated a customer's Valcom paging system with their Cisco VOIP solution. They have callback buttons in the classroom that are simply plar'd back to a single extension on their voice gateway. Problem is they used the callback button this week and the receptionistw as on the phone and it went to her voicemail and it was an emergency.
The easy answer is to plar it back to a hunt pilot and have it ring several people and never go to VM but I wanted to see if there was a way to make it drop the call the receptionist was on or to barge in on it at least. I am guessing not but wanted to check.

There is some way of setting a pre-determined timeout
- it differs for different drivers and database, but
google around and you should find it.Statement.setQueryTimeout()
You can also set the max number of rows returnedStatement.setMaxRows()
And of course keeping in mind that the driver might not support these.

  • Zones not booting - failed to create devlinks: Interrupted system call

    I just installed the latest 10_Recommended cluster with 118833-36 kernel patch and now my zones won't boot. I get the error:
    (root)Yes Master?> zoneadm list -iv

    zoneadm: zone 'test': could not start zoneadmd
    zoneadm: zone 'test': call to zoneadmd failed
    Also, running devfsadm or drvconfig;devlinks from the global zone will core dump.
    Any ideas..??
    tia..

    First, you gotta change your prompt to something less embarrassing when you post to a public forum :)
    I'd forget about the zones problem and focus on why devfsadm core dumps -- that's the core of the problem (no pun intended...no, really!).
    First, review the install logs of all the patches installed during the recent service (/var/sadm/patch/*/log). Even if they all show a good completion, check the messages they generated, sometimes they have errors that aren't bad enough to cause a complete failure of the patch. The KJP (118833-36) is probably a good one to start with.
    Next I'd "truss" the devfsadm command while it core dumps then get a stack trace of the core (run "adb <corefile>" and type "$C" -- that's old school, I'm sure mdb is much cooler...).
    Throw some of the strings from those against sunsolve and see if something sticks.
    Good luck!

    We apparently had quite a bit of premature thread death, about half of our threads

    Ummmm.. so you set the executeThreadCount to what? 55? And PercentSocketReaders
    to 50?
    And you are missing execute threads 1 through 25. Where did they go?
    The only
    threads you have left are the ones listening for requests - and they
    don't do
    any work. Find out what happened to the missing threads.

    If I am playing a song from my phone on speakers, how can I make sure that there are no interruptions like calls or notifications? My students are performing and it would be terrible if there was to be an interruption.

    You could turn on Do Not Disturb. This would block all notifications and incoming calls.
    Or just turn you're phone's Airplane Mode on if you're not streaming the music

  • Does anyone has Siri come on without request and interrupt phone calls?

    Hi,
    I have an issue with Siri on the IPad. It comes on without my request.
    I also had my music start in the middle of phone conversation and interrupt my call on the IPhone.
    Two different devices with interruption with out a request by me. crazy!

    I haven't had that issue, but thanks for asking.
    Do you have a technical support question?  Don't see one in your post.  Please ask, and detail any troublehsooting steps you've taken thus far.

  • How do I stop SMS tones from interrupting my call?

    When I'm on a call ifi get an email or a text message the alert that I have assigned to it interrupts while I'm on the phone and I can't hear the person I'm talking to

    Flipping sthe witch isn't the proper fix. Ever forget to flip the switch back after the call & lay the phone down & then find out later that you missed calls & texts?  Plus, when the phone is in a case, hard to flip the switch.  Then even harder if your wearing gloves & you are using your nose to swipe across to answer the phone.  Only way to get it fixed, is to write apple & make the suggestion to fix it.
    I do not recall any of the other iprevious OS versions having this problem until the most recent one.
    There's no phone setting to silence alerts during phone calls.  You can suggest this to Apple: http://www.apple.com/feedback/iphone.html

  • Handling Application Interrupts (Phone Call, SMS, etc)

    I am trying to get a feel for my options when it comes to handling application interrupts in the form of phone calls, messages, pressing the home button, etc. My google search the other day brought me to a page showing a series of events fired when receiving a phone call, but I seem to have since lost that page.
    My question is, when those events occur during the execution of an application, what are the names of the events and when I intercept them, how much time does my application have to react before it is rudely exited? Also, does the Home button throw any sort of event sequence I can read within an open app?

    Look at the UIApplicationDelegate docs. You will get 'applicationWillResignActive' and 'applicationDidBecomeActive' when interrupted and returned respectively.
    Depending on your app there may be nothing to do or a lot to do with there. Pause a game, deal with current network requests etc.
    It's easy to trap the Home button. When it's pressed you will get 'applicationWillTerminate'. Then your app exits.

  • Trying to interrupt an RMI call

    We're trying to interrupt a call to a Weblogic RMI stub via
    Thread.interrupt(). Doesn't seem to work. Can someone confirm that
    this will never work, or might we be doing something wrong?
    Why is this posted to the performance newsgroup? We're trying to build
    a web service with a guaranteed response time. The servlet makes a
    backend call via RMI. Before we make the RMI call, the servlet thread
    requests another thread to interrupt it if the call takes too long. If
    we can't interrupt the calling thread, there are only two options I can
    think of. 1) Have the servlet thread pass the request to another thread
    that can block. The servlet thread then waits on a queue for a
    response, and can be interrupted. 2) Don't use weblogic RMI, and build
    our own transport. Yuck.
    Any ideas?

    Ok, I'm just kidding. We'll just start with the guaranteed process

    That's what I thought :>

    I'd be surprised if no one else has run into this issue with RMI. A
    collegue of mine is building a test with Sun RMI to see if that is
    interruptable. It seems that Weblogic might be catching the interrupt
    exception below the stub level. When we interrupt a thread blocked in
    an RMI call, the thread returns normally (after completing), and
    Thread.isInterrupted() is false. I think that means that something in
    the call is reseting the status. A quick glance at the generated stub
    code does not seem to indicate anything, so I'm guessing it's at a lower
    level.
    Well, it depends on what we are doing when you attempt to interrupt our
    thread. Most likely (since it's a stub waiting for a response from the server)
    the RMI thread is blocked in a socket read system call. Depending on the
    operating system and how javasoft implemented it, it may or may not be
    interruptable.

  • Call interrupt is possible in blackberry

    Hi All,
    This post will be posted here or not. I dont know. Please execuse and give me the response
    I need small help about call interrupt. I explained below what i am need.
    For example i am developing small application. when ever installing the application in mobile, application will run in background. At that time we will try to make a call to friend or some one for ISD, or STD like.
    Actually here we pressed only 10 digit number(Ex:9986866605) direct from mobile not through our application.
    For example this 10 digit number(EX:9986866605) is STD, Now what i  want automatically +91 will be added with this number and dialed the number automatically(ex:+9199986866605) through our application using related API.
    [B]Mainly first what i Need:[/B]
    1. Blackberry is supported to call interrupt or call generation
    2. If supported which API is supported.
    Please if any body knows about Let me know as early as possible.
    please.
    Thanks,

  • Running thread behaviour on calling interrupt?

    if a thread T1 is running and interrupt is called on this thread,there will be no impact on thread T1 processing/behaviour. To handle this
    we have to call if (Thread.interrupted()) inside run method of thread T1 right?
    Interrupt will have impact when thread is under wait,sleep or join(or methods that throw InterruptedException),Right?
    In above question , impact refers to the case when InterruptedException will be thrown.
    Asked the question at http://www.coderanch.com/t/545582/threads/java/Impact-interrupt-Running-thread but did not get satisfactory reply though i have been thru api doc.

    Interrupting a thread sets a flag for that thread. Setting that flag will cause some blocking operations to throw an exception. e.g. sleep, wait, NIO read. Unless you do one of those operations, setting the flag doesn't do anything which is a problem for those who hope to stop a running thread in an untrusted third party library. ;)

  • Wait - interrupt  Why Exception not thrown?

    Hello. I expected that calling interrupt() on a waiting thread should result in InterruptedException thrown by wait(). Nevertheless, in the code below no Exception is thown as if there were no interrupt() call. Actually this snippet prints the same output irregardless of whether interrupt() is called.
    public class Runner {
        synchronized public void foo(){
            System.out.println("before wait in foo()");
            try {
                wait();
            } catch (InterruptedException e) {
                System.out.println("InterruptedException");
                e.printStackTrace();
            System.out.println("after wait in foo()");
        synchronized public void bar(){
            System.out.println("before sleep in bar()");
            try {
                Thread.sleep(10000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            System.out.println("after sleep in bar()");
            notify();
            System.out.println("after notify in bar()");
        public static void main(String[] args) {
            final Runner runner = new Runner();
            Thread t1 = new Thread(new Runnable(){
                public void run() {
                    runner.foo();
            Thread t2 = new Thread(new Runnable(){
                public void run() {
                    runner.bar();
            t1.start();
            t2.start();
            try {
                Thread.sleep(5000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            t1.interrupt();
            System.out.println("t1 interrupted");
    }

    Thanks for your response.
    Still the whole thing is not clear to me.
    Why InterruptedException is not deterministic in this
    case?
    Where is the ?non-deterministic? code in this
    example?The fact that t1.start() is written before t2.start() in you code does not guarantee that foo() method will always be called first. Either the bar() method or foo() method can be invoked firstly, because this is how threads work in Java. Try to invert: put t2.start() before t1.start(), and see what happens. Probably the exception will be thrown in this case, but this behaviour is still non deterministic.
    Please pay attention to timing -
    t1.interrupt() is called in about 5 seconds after
    both threads are started, at the time when one thread
    is in sleep(10000) and the other in wait(). I believe
    that above condition may be taken for granted taking
    in account 5 seconds interval between calls.You know that when you invoke the notify() method inside the bar method() you are making the foo() method not waiting anymore, don?t you? Therefore, if foo() method is called firstly, then the InterruptedException probably won?t be thrown. I said "probably" because the behaviour is non deterministic. Time is relative. If your processor is fast, then probably the exception will never be thrown, but you will never be completely sure. Maybe if there are other executions using your processor, then the processor might be slow for your program, and then the InterruptedException might be thrown. If you want to make your program have the same behaviour always, then you have to use semaphore variables, that indicate when exactly one thread is permitted to run.

Maybe you are looking for
