    Unhappy cannot establish a connection with a certain number....

    hello!

    i have this program where i'll call several numbers consecutively...
    when the program calls, SOMETIMES it cannot establish a connection with the other gsm devices... so i assumed it normal...

    but then there's this certain number that i tried calling using my program. My program hasn't been able to establish a connection with it Eversince i tried calling.... i already tried switching/changing the sequence of the numbers to be called... but still having the same problem... i tried calling it using my phone, and it rang... how come? what might be its cause?

    and... what are the possible reasons why i sometimes cannot establish connections?

    anybody?

    Are you calling from the computer from one number/line and manually calling via another like a cellphone?

    Maybe if you post your code, members can check if there is any logic issues etc.

    Have you tried another number from the same network provider?

    Sounds like a telemarketing program calling all kinds of numbers in a list.

    i really dont think it's a "logic issue" at all... cause when i try a different number - it works. this certain number is the only number - so far - that i cannot establish a connection..

    You may want to show us those phone numbers, at least. Or just a phone number mask that is represents the significant difference between these working and nonworking numbers.

    Also it could happen that you just got some limitations on your phone calls. Just like a wired phone cant access a gsm or vica versa.
