  1. The problem is packet loss. T.38 compansates packet loss. That is the reason why T.38 has been specified. Unfortunately, they made it very complicated, so that the product support is still quite poor.

     

    The PBX has the additional problem that it has to maintain a constant RTP playout rate. If the input side has too much jitter, the PBX starts to insert packets on its own. For voice that is great, but for Fax it is desastrous.

     

    All in all, the bottom line is that you cannot transport Fax over the public Internet using G711. BTW the same is true if you are using compressing codecs.

  2. Yea that is a real problem. We need to (finally) address this in one of the next versions.

     

    I guess the best way to do this is to call the extension that parked the call and say something like "hey there is a parked call that has not been touched for so and so". Alternatively, we could give the caller the option to press a key and go back to the operator. Maybe even automatically after a timeout. Then at least they have a better option that just hang up.

  3. There were a few problems that have been fixed in 2.0.1. First, the 2.0.1 fixes an important bug when deleting non-extensions. And it fixes another bug where the extensions count could be ignored. And last, there were keys which simply mixed the "accounts" and "extensions" up. So all in all, the 1624 build should fix all known license problems, and you might need to check your license key. You might use this link to check what is in your license key: http://www.opinionatedgeek.com/dotnet/tools/Base64Decode.

  4. Well, well, it turned out there is really a bug in the licensing part.

     

    When deleting a account (except Extension and CO-Line), the license count was not decreased.

     

    Workaround: Manually delete the corresponding file from the file system and restart the service. Well, that is not really an option.

     

    Therefore we made a new version 2.0.1.1624 what should fix this problem.

  5. We have put version 2.0.1 on the download page (http://www.pbxnsip.com/downloads.php). The release notes can be found at http://wiki.pbxnsip.com/index.php/Release_Notes_2.0.1.

     

    Upgrades: We believe that the 2.0.1 fixes several important issues that we found in the 2.0.0 release. If you don't experience problems with the 2.0.0 release, there is no need update. However, if there should be open issues with the 2.0.0 installation, we recommend to move to 2.0.1. We recommend to backup the working directory and the pbxctrl.exe executable before performing the upgrade.

  6. accounts: 10

     

    Well, that might be the problem. I guess this should be "extensions". Otherwise the total amount of all accounts will be 10, but you shoould be ablt to have more. I guess you will receive a new license key shortly...

  7. First let me state that we are still running version 1.5.1.6

     

    I would definitevely upgrade to 1.5.2.7 (see http://www.pbxnsip.com/downloads.php). This is a relatively painless upgrade, because all you need is to replace the executable. You can still keep the old executable, and also move back without pain.

     

    The whole redundancy thing depends on the error code that is returned. There is a setting for this in the trunk. Did you try that? What error code is being returned?

  8. Maybe there is a problem with your license. For example, if you created the attendant with the demo license, and then later got a "smaller" license, the PBX will probably allow the deleting (sic!), but not creating a new one.

     

    There is a little trick that shows you what the license actually contains. For example, you can use the following link: http://www.opinionatedgeek.com/dotnet/tools/Base64Decode, enter the license code there. Then you can see how many of each type this license contains.

     

    If the problem persists, please send the license back to sales and ask them to give you a new one.

  9. Let me try to understand this 100 %.

     

    So lets say the PBX receives an incoming request from 2121231234 to 9781231234 - which belongs to "Company A". The receptioning is registered at extension 123. The packet going to the phone would look like this:

     

    INVITE sip:123@192.168.1.2;line=123 SIP/2.0

    From: "2121231234" <sip:2121231234@localhost>

    To: "Company A" <sip:9781231234@localhost>

    P-Asserted-Identity: "2121231234" <sip:2121231234@localhost>

     

    The phone's job is then to display the "Company A", so that the receiptionist is able to say "welcome to company A - how can I help you"?

     

    The way to do this is to use the address book. The PBX changes the display name according to what is in the address book, also for the To-header.

     

    I just saw that this is a bit difficult if you are using the 2.0.0 version (thought not impossible!). In 2.0.1 this will be the default behavior.

  10. Ok, lets clarify this:

     

    For outgoing requests coming from a trunk, the PBX is able to answer BYE challenges.

     

    For incoming requests that are sent to a trunk, the PBX does not challenge BYE requests.
