    Hi Diego<br>
    <br>
    As I told you , I believe your problem is not related to the mfcr2
    variant.<br>
    This seems more like a timing, phisical or drivers problem to me.<br>
    <br>
    You use Sangoma and Wanpipe , and I have not experience in those.<br>
    <br>
    Can anyone check if this might be related to a hardware / drivers
    issue?<br>
    <br>

            Hi Diego<br>
            <br>
            I have been working for a while in Barranquilla with both
            PSTN providers (telecom , Metrotel).<br>
            You should try the Argentina variant of MFCR2. (AR), it
            works fine for me.<br>
            <br>
            Anyway, I believe you have a problem apart from the
            signalling variant. can you please post your system.conf
            (dahdi) configuration file and your chan_dahdi.conf<br>
            <br>
            Regards,<br>
