    SUMMARY

    2 years ago we started evaluating the technical and economic feasibility of a full migration to an IP telephony platform. We analyzed different versions of Asterisk on several distributions of SO Linux in virtual environments. Finally choosing an integral solution type. We the first prototype of Elastix v1.2 32-bit on a real server using clones of Digium boards (Motorola chipset Modem / Intel) and FXO to PSTN. After that, the authorities took the decision of changing.

    We started the suitability of the data network for use with VoIP. We used Intel Xeon Server Installation / HD 500 GB as a first PBX. It began with the installation / configuration of 10 extensions Grandstream GXP2000 model. We utilized Sangoma A200 Analog Card with 4 FXO for PSTN access.

    In the next stage is wide Sangoma A200 Analog Card with hardware echo cancellation for a total of 24 FXO. 100 extensions were added at the headquarters of Rectorate. The Hardphones used are: GXP2000, GXP1200, GXP280, BT200. Operator consoles were added with more than 100 BLF (busy lamps fields). 10 video phones Grandstream GXV3000 were installed too.

    In the next stage incorporates a new Elastix server of the same characteristics as before. It was located on the Campus. It consists of another card Sangoma A200 with 24 FXO ports. Both servers are interconnected through IAX2 Trunks and a dedicated wireless link of 22 Mbps. We added 100 extensions to this server.

    The purpose of having 2 servers with their own routes / trunks for PSTN access is guarantee the communication between Rectorate and the Campus and provide access to PSTN at both ends.

    There is also 15-connected devices FAX Telephone Adapters (ATAs).
    It has 20 virtual fax (Hylafax) redirected to email.
    It has access to FAX from PC Winprint Hylafax.

    Freepbx module was installed (CUSTOM-CONTEXT) to manage access to PSTN by groups.

    It provides conference calling, call transfer, directly or with notice, group call, call forwarding, ringing groups, interactive digital receptionist (IVR).

    A2Billing is configured for use with different users, with billing and pre-paid calls.

    Now, we are deveveloping applications (AGI-PHP) for database query. Teachers and students may access important information via voice synthesizer (Festival).
