New Smartswitch release: 6.0

2010-05-04 09:19:39
We are glad to present a new 6.0 production release of the Smartswitch.

This release contains significant amount of features and fixes comparatively to previous 5.3 release. Some of the changes are heavy, therefore we decided to increase the major number to 6.

The list of most significant changes:

  • The open-source software that is included into the distribution has been updated:
    • FreeBSD to 7.3;
    • Asterisk to;
    • MySQL to 5.1.45.
  • Added a russian user's guide;
  • Implemented access server on the basis of XML-RPC protocol to enable linkage of the system with third-party applications (for example, with web-store with dynamic user registration);
  • Web-interface changes:
    • Added the role-based access permission system. You can flexibly assign authorities to each employee of your company;
    • Automatic channels and sessions pages reload has been implemented. You can configure the period of reload;
    • Web-interface changes logging has been implemented. This enables you to see who and when did each and every change in the configuration.
    • An ability to configure the widget classes have been added. This enables you to define custom web-interface control options for administrator and customer web-interface (for example, redirection configuration options);
    • An ability to refill with the PIN code from the subscriber's web portal has been added.
  • Media handling changes:
    • Options for control for the Differential Services field in the IP packets for RTP streams has been added. More likely that the voice quality of the voice stream going through the system will significantly improve after this change;
    • Added support for NAT, RTCP and UDPTL (T.38 faxes) in Media Proxy;
    • Media Proxy can be enabled or disabled per each peer independently (on the contrast to the global setting that was in 5.3).
  • SIP changes:
    • new options for registration;
    • enhanced support for T.38 faxes(due to migration to 1.6 branch of asterisk).
  • H323 changes:
    • added NAT support;
    • added possibility of working with peers via different network interfaces;
    • fixed several critical vulnerabilities in openh323 library, which lead to sporadic call hangup on the load over 100 calls.
  • several critical vulnerabilities in asterisk have been fixed. Digium has already committed some of them into their mainline;
  • n-way conferences with dynamic participant gathering and correct billing has been implemented;
  • Billing changes:
    • a core engine has been refactored to support further enhancements;
    • safe synchronization of transactions have been implemented (to protect situations when someone might want to compromise the system doing actions like transferring funds from one account to another);
    • Proper online balance control in the real-time mode for answered channels has been implemented. This solves a billing issue "to hangup when balance is 0" for the calling cards platform when there are several simultaneous calls from one customer. This feature also might be useful when working with the wholesalers on the prepaid basis;
    • a calendar write-off method (making write-off for all the customers at the same specified time, for example, at 00:00 of the first day of month) has been implemented
    • an option to configure a credit for company of retail customer has been added;
    • new feature: consumption profiles. You can configure the amount of minutes or the money amount for particular destination set and for particular time period. And you can configure billing for this set of rules to differ from the regular one. This enables you to configure rules like "1000 minutes per month for Australian destination codes are free of charge";
    • You can configure billing to not to alter the balance when the call is over (this is mainly used with consumption profiles).
  • IP-routing configuration has been added to web-interface;
  • An option to configure and control periodic processes in the system has been added (for example, you can change periodic write-off period or system load graphs update period);
  • Added MP3 support for file and music on hold playback;
  • One more step towards virtual PBX: an option to configure custom sound files for the retail customer that overwrite generic ones;
  • Internet-billing implementation has been started: a VPN-server MPD has been added to distribution and linked with the Smartswitch. VPN-server is used to connect the customers via tunnel (for example, from the mobile devices. In some countries cellular providers block VoIP traffic and this helps to overcome this)
  • A new option - per-node call limit has been added. This allows you to limit the maximum call amount passing through the node in order to not to have voice quality degradation in period of system overload. This combines well with cluster mode of operation, when customers operate on several IP addresses of your cluster. In case when one of the nodes is overloaded, customers get indication 'Switching equipment congestion' and switch to other node of your cluster.

New product: Easy Gentoo

2010-02-01 12:41:08

Our company's product portfolio has been extended with Easy Gentoo - a free Linux distribution, that has been developed on the basis of Gentoo.

Distribution is a 100% authentic (without modifications) Gentoo system, that is installed by Debian installer.

Distribution will be basic for the Linux-versions of the Smartswitch product.

The reason for building our own distribution is that none of the existing ones completely fits our needs.

Meet Smartswitch 5.3

2009-11-19 10:28:15

Only 2 months have passed, and we have a new release of innovative system for telephony!

Meet following features in the new release:

  • Configurable outbound call handling.

    Sounds complicated, but really it's very easy. Giving a simple example, where this might be handy.

    Imagine that you have dozen of telephony providers and one of the has awful quality (but cheap) . And you want to notify a user, that the call will go through the bad route in case if hunting choses this provider. It's hard to imagine, how to implement this on similar products, isn't it?

    But we have this configurable very easy, in a matter of few seconds! Simply configure the outbound call handler in the Call handler GUI - add Background node before Dial node.

    And this is just an example. You can configure absolutely custom outbound call handling!

  • Media Proxy.

    This was made by our company from scratch. Similar stuff is absent in a standard Asterisk distribution. This module brings us to a brand new level and therefore we can offer our product to companies with great call amount;

  • Billing packs generation.

    Just imagine, that you have dozens of providers configured, with different price sets on great number of destinations, with different activation times, with different time-based prices (night/day, working/weekend), and, at last, with different currencies. Also, prices update all the time!

    On the other hand, you have to give prices to your customers basing on provider prices taking into account profit margin, in fixed currency , with fixed time-based prices and activation time. And you have to do this beforehand.

    Is this situation similar for you? Manual work seems to be simply impossible in this case. Situation complicates as soon as the number of providers increase.

    Fortunately, with arrival of automatic price-list generator you completely wash your hands off this problem!

    This utility not only generates prices basing on what was said above, but allows to choose the profit margin calculation mode: either relative (in percents) or absolute (in currency);

  • New options for statistics selection;
  • New options for prices selection;
  • Extended regular expressions (perl, sed, literal syntaxes);
  • Possibility of setting the extension for SIP registrations;
  • Extended hangup causes (ISDN codes) in statistics;
  • Added following new PBX functionality:

    • Group pickup;
    • Virtual Fax. You can accept faxes not having a fax-machine at all!

  • Support for queues - solution for the call-centers;
  • Improved mailing subsystem:

    • New possibility to send mail from your company's mail accounts .

      This is needed first and foremost to enable your technical support service to receive answers to the letters, that have been automatically generated by the system (for example, alerts about service degradation, that are being sent to your providers). You could setup mail forwarding on your mail exchanger for this case;

    • A Voicemail to e-mail service;
    • A Fax to e-mail service;
    • The sent mail report.

  • Telemarketing.

    At the moment service is limited with batch SMS sending to specified recipients, but soon we'll have much more functionality here!

1700 revisions in 2 months from the time of last release speak for itself regarding the amount of work done!
