    Hi everyone, could somebody tell me which phone´s brand or model will store the RPLMN in its file?
    I mean, there are some phones which does not store the RPLMN and other ones does it,is it a matter of brand or model? I tried Nokia 6101 and it does not do it, but I do not have chance to test it in other Nokia models.
    Thanks a lot.

    Line Reversal was used with Analogue Networks. Classic Coin and Fee Checks with Payphones.

    For Signalling C7 / ss7 is ubiquitious. Some Networks (legacy
    requirements) still support R2 MFC signalling.

    For Landline solutions with a Local Loop (Two-Wire interface), a line reversal is used to provide “wetting current” before CLI is sent to the CPE. Line Reversal, FSK (CLI) followed by the Ringing Current (from the CLIC).
