I did not make myself clear, this feature already is implemented in mgetty. I just added one record to the table which contains recognized prefixes for caller id. I don't have patch. How about concurrency ? If the traffic is so big that it is possible that two users are calling at once, we may be stucked. I don't have experience with ISDN. But there is one trick that may help : we have two GSM modems connected, two mgetty's and one modem is primary. We set up primary modem to divert calls when busy to the other, and don't have rejection ! I hope this is possible.
