    Hi Diego

    

    I have been working for a while in Barranquilla with both PSTN
    providers (telecom , Metrotel).

    You should try the Argentina variant of MFCR2. (AR), it works fine
    for me.

    

    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

    

    Regards,

        Hi, EveryBody.
        

        
        I have some problems with a MFCR2 Protocol and Colombian
          TELCO. Some calls hungup or after answer the operator and
          other calls reamin silent.
        

        
        The main problems are:
        1. The channels are swithching between "Zap alarm" and "Far
          en ublocked on chan.."
        2. Protocol Error, INVALID CAS
        3. Protocol Error...  Invalid
            Multi Frequency Tone
        

        
        I need your help to fix it, I teste itu, ar, br variants
          and the issue didnt fix. Please any advice will be ready for
          testing
