PAP2T-NA to PAP2T-NA call via Internet - Llamada PAP2T - NA a PAP2T-NA Internet


The ringer is a result of signaling sip of send/receive.  The flow of the voice is the result of send/receive rtp packets.  If you do not properly receive the rtp packets, the problem is usually associated with the transverse NAT of your router.

If NAT Mapping Enable does not solve the problem in itself, the usual challenge is to use a STUN server part 3d in order to help the adapter to determine its external ip address and external port numbers.  You can use any STUN server as a standard feature.

Under the tab line
NAT Mapping Enable: Yes

The Sip tab
Replace WITH Addr YES
Send an RESP for Src Port: YES
STUN Enable: YES
STUN server: (or any other)

  • Recently, I built a new computer and used my old hard drive. Now, I can't activate Windows XP via internet or telephone?


    I recently built a new computer with a new motherboard, processor and RAM.  The computer works well, but I can't go through the activation of Windows XP.  I tried connecting via internet, and he said that I didn't have a connection, which I know that I do because I can connect to the internet on my motherboard cloud browser.  I tried to call the number that was given, but the computer says that it is not a valid product.  I know that my copy of Windows XP is valid - in my old system, it worked fine.

    Please help me to activate my version of Windows XP.

    If the old version of Windows XP is installed on the computer when you bought it, you invalidated the license by moving the hard drive to a new system.  This license lives and dies on the parent computer/card origin.  If it was a copy of the (bought in a store) retail of Windows, I'd recommend replace because move one disk hard from one computer to the other, sometimes translated as difficult solve incompatibilities due to driver problems.

    Thanks for your reply. for the remote panel connection manager, it seems like a good solution, but not in my case.

    and for the static ip address: Yes, it is the ip of the server. and the client must connect to send data (signal dmm---> dynamic signals). someone tell me try the command ping sataic ip of the client computer? and the result is request expire. I think that's the problem and I'll solve it so wish me good luck gd

    It was good adice you received. Non-routage IP are available only on the local network. Your IT Department will have to help with the IP settings and router.


  • PC cut his all when I called via Skype or use other programs

    A few months ago I bought a new desktop pc HP Envy and I'm really deal with it, but recently I'm under problems.

    A couple of weeks, my PC started all my audio muting for no reason when I got a call via Skype, at first it wasn't a problem because I could use other programs such as Teamspeak or mumble, but recently these programs get the same problems as well.

    The standard solution to make sure that the checkbox in the communication tab is set to "to do nothing" is checked as seen on this page,

    I tried all possible combinations in the tabs in my reading and recording, but it still doesn't work.

    I added some screenshots that show what it looks like.

    Hello @Archangel52210,

    I understand that you are having problems with your new computer running Windows 8.1 where the audio is automatically inhibition. I'm you provide a document from HP support: use of the Recovery Manager to restore the software and drivers (Windows 8), which allows you to restore the original supplied with your computer drivers. As these drivers and their settings are working I think they once again and I hope when they are updated the next time Hey take better.

    Please re-post if you need extra support. Thanks for posting on the HP Forums. Have a great day!

    my friend told me while updatng windows via internet, virus attacks. is this true?


    He's probably referring to the malware that can attack a system if no firewall is running the
    the installation is complete. Happened a bit with Windows XP. Vista comes with a completely
    Firewall active and should not have this problem. In fact, the problem was fairly well controlled
    with the active firewall included with Windows XP SP2. Firewalls are active and enabled by

  • Problem WinXP SP1a installation via internet

    This is similar to post Russ Maxon

    "When installing Win XP SP1a via internet, the microsoft web server isn't reachable. Instructions error msg telling me to go to the website of MS XP Service Pack and click on "Problems downloading the Service Pack" for a version of the SP1 update that does not require any interaction with the web server. "I can't find this place to get these instructions, so I can complete my reinstall the upgrade of Windows XP.

    I use a Dell Inspiron 4100 laptop with a whole new hardisk Samsung160Gb and running Windows XP.

    I do a full reinstall as previous hard drive was no longer functional.

    I installed the XP Home and Office XP Professional operating system from the original disks.

    I have a wireless internet connection via VirginMedia using IE7.

    Automatic updates says it won't work because the system is not up-to-date - not very useful.

    I try to make updates in the order and have read various bits of advice on the Microsoft Web site on the upgrade: for example all upgrades are cumulative, this SP2 requires no SP1; but SP3 requires first of SP1a or SP2. That's why I tried to use SP1a Express download, after which I got the above error message.

    In your response to Russ Maxon, it has been suggested that he go directly to SP2, but it doesn't seem to be an independent download for SP2 for home use, only for network deployment.

    Thus, the crucial questions are, exactly where full versions of SP1a and SP2 are drawn.

    Hello MalTom,

    Visit this link on my site:

    The information on this link to download the Service Pack 2 on the download site. Yes it say the deployment of the network, but ignore that, simply download the full service pack and install it.

  • Can connect with desktop remotely all directions except via internet Windows XP to Windows 7

    I have a new computer with Windows 7 Pro to work I need with desktop remote access so that I can work from home and be with the family.  For years I used remote desktop connection from home using Win XP SP3 to my Win XP Pro SP3 computer at work.  I am able to connect my old WinXP computer work on my new Win 7 computer (locally).  I can connect from home computer Win XP Win XP computer via internet (DSL) to work.  I can connect from Windows 7 computer to work at Windows XP home computer over the internet (DSL).

    So, I have Setup port forwarding or modems DSL correctly, the IP addresses are correct, consistent remote desktop clients. Firewall exceptions are configured correctly.

    What is different.  The new computer with Windows 7 Pro has McAfee Internet Security all others running EAST of Kaspersky.  Win 7 computer is new.  Since I am on various possibilities of connections, changed listening port of 3389 on some computers, including the new Win7 computer (this should not be a problem that I'm able to connect locally).

    Disable the firewall (software Anti-anti-virus/IS) on both computers does not help. In any case, I can go to WinXP Pro to work on Win 7 computer to work locally.

    My thought is that there may some security policies, or maybe a protocol problem which is different with the new Windows 7 computer that does not have a connection outside the local network (via a public network).

    I also tried to set up a VPN connection integrated Microsoft: forwarded port 1723, the GRE protocol allowed to the DSL modem.  Tried all different scenarios between Win XP Home and Win 7 computer at work and cannot configure the VPN connection. I get error 678: the remote computer did not respond.

    I spent hundreds of discussions help/knowledge base and discussion review.  I have seen or followed all the instructions on the various sites of tech Web to configure VPN connections and Remote Desktop connections.

    Does anyone have an idea as to what could be the solution here?

  • Why CRLF are treated differently when called via bridgetalk?

    I stumbled upon another mystery: when I run a script directly in ExtendScript, he interpreters '\r' as a CRLF. Yet, when I called him by bridgetalk, the '\r' was left as text.

    This strange behavior is if I set the target to photoshop or not. Can someone tell me why please?

    Here's the unit test (CS6, Windows 10)

    -L' script call:

    #target bridge

    var bt = new BridgeTalk;
    BT. Target = "photoshop."
    var myPath = "~ / Desktop/testCarriageReturnSubstitution.jsx ';"
    var ScriptFile = new queue (myPath);
    fOpen var = ('r');
    script var = ();
    $.writeln (script);
    BT. Body = script;

    BT. Send();

    -Test script:

    #target photoshop

    var badString = ' \rTitle\rCity, State - USA December 2015 ";

    var nouvelleChaine = badString.replace ('\n', "\n");

    $.writeln (badString);

    $.writeln (newString);

    The runtime directly via ExtendScript result:


    City, State - USA December 2015

    Result: not defined

    Result when called via the calling script:

    Result: true

    \rTitle\rCity, State - USA December 2015

    Thank you

    / Tim

    Thank you, Uwe for responding! I tried that before posting, and the result was '\\r '. It seems bridgetalk converts these escape characters to the text.

    I found another thread (Re: \n doesn't work does not correctly) addressing the question, pointing way back to CS2 times! Wonder why Adobe does not solve the problem, and/or documenting this bug to save us some headaches, or maybe they he documented in a dark place.

    Workaround to this problem is to use decodeURI and use the hexadecimal code for these special characters. In my original unit test, I have changed the script photoshop for the following:

    #target photoshop
    var title = "title text";
    var CityState = "San Francisco, California";
    var badString = ' \r'+Title+'\r'+CityState;
    var goodString is decodeURI (Title + "%0d" + CityState);.

    $.writeln (' string bad encoding: ', badString);
    $.writeln (' string right encoding: ', goodString);


    A string of bad encoding: \rTitle Text\rSan Francisco, California

    Right channel coding: title text

    San Francisco, California
