Problem: Modem Connection Via ATA failing
1) Using a Symbol SPT1800 Docked in a Symbol Cradle (Model # CRD1700-1000M-1)
2) ATA 186/188 running Firmware ATA030203SCCP051201A.zup.
3) Call Manager Version 4.1(3)sr4d
Cannot get a connection with Symbol SPT1800 Docked in the Cradle and attached to ATA186 or ATA188 to the device on the other end. Unit dials fine and tries to establish a handshake with the device on the other end but is never successful. Modem handshake tones sound funny/not normal.
All works fine and sounds normal with the same Symbol SPT1800 and Cradle when connected to POTS line from telephone company.
