ISDN Switching between BRI and PRI Interface

    Hello,

    I have a 2811 router which has one VWIC-1MFT-E1 connected to the PSTN,
    and one VIC2-2BRI-NT/TE connected DIRECTLY to one router and one modem
    (not Cisco ones). The 2811 is a H323 gateway that works properly for
    voice with CallManager and Cisco IP Phones (whose reach external number
    through the PRI interface).

    The router and the modem (whose handle data) need to access to the PSTN
    through the PRI interface (for remote maintenance purpose). I mean the
    2811 needs to proceed the switching between its BRI interfaces and its
    PRI interface properly!!!

    We've managed to make ISDN switching to work in our lab with one 3640
    router with two VIC2-2BRI-NT/TE (one connected to the PSTN and one
    directly connected to a router). So, I don't know why it's not working
    with a 2811 between a BRI and a PRI???

    Does someone know how to make this configuration working ?

    Thanking you in advance,
    Regards,

    Benjamin
