Hi ! I don't know that is a ser problem but I cannot make a call from ATA-186 ( with analog phone) to PSTN phone via my gateway. I receive 400 Bad Request - Invalid IP address If I call to IP everything is ok.
I don't have this proble when I call from softphone like kphone to PSTN phone.
Did somebody have similar problem ? Which version of ATA software do you use ?
