Hello All, I am a newbie to FreeSWITCH, and have been experimenting with it. I am currently facing a problem, which, to be honest, I am not sure if is a FreeSWITCH misconfiguration problem, or if it is totally unrelated! My setup is as follows: Serial port based device(Caller)->Dlink dialup modem(DFM562E)->PBX->Sangoma A102 E1 Link(and FreeSWITCH)->PBX->Dlink dialup modem(DFM562E)->Server(Receiver) Problem: When the caller makes the call (using the modem with a lower baud rate 1200), Receiver modem receives the RING and answers the call (using the ATA command). But for some reason, both the ends timeout waiting for modem CONNECT.
