    Is anyone using 3CX with ISDN30 (PRI) there appears to be very little information with the exception of 3cx stating they were testing with pika cards back in April.
    Thanks Dave

    Hi,

    Are you using E1 IDA-P (ISDN/PRI)?

    We have already finished the T1 IDA-P (ISDN/PRI) test. Everything OK. Except the Calling Line Identification (CLI) unable to customize at 3CX. It can be overcome by Teleco do some mapping job. Up to now, we only found ONE provider unable to support 3CX CLI. We already work with gateway manufacturer to modify the firmware for fixed this issue.

    For PIKA, we will plan to study.

    HI davelorduk,

    These ISDN channels are delivered to the user in one of two pre-defined configurations:

    Basic Rate Interface (BRI)
    BRI is the ISDN service most people use to connect to the Internet. An ISDN BRI connection supports two 64 kbps B-channels and one 16 kbps D-channel over a standard phone line. BRI is often called "2B+D" referring to its two B-channels and one D-channel. The D-channel on a BRI line can even support low-speed (9.6 kbps) X.25 data, however, this is not a very popular application in the United States.

    Primary Rate Interface (PRI)
    ISDN PRI service is used primarily by large organizations with intensive communications needs. An ISDN PRI connection supports 23 64 kbps B-channels and one 64 kbps D-channel (or 23B+D) over a high speed DS1 (or T-1) circuit. The European PRI configuration is slightly different, supporting 30B+D.
    BRI is the most common ISDN service for Internet access. A single BRI line can support up to three calls at the same time because it is comprised of three channels (2B+D). Two voice, fax or data "conversations," and one packet switched data "conversation" can take place at the same time. Multiple channels or even multiple BRI lines can be combined into a single faster connection depending on the ISDN equipment you have. Channels can be combined as needed for a specific application (a large multimedia file transfer, for example), then broken down and reassembled into individual channels for different applications (normal voice or data transmissions).

    I think we are using almost the same standard ISDN/PRI. For more details, please contact your local Telco.
