S0=2 will have the modem answer after 2 rings.
S9=1 is the Carrier detect response time.
Define the length of time a signal is detected and qualified as a carrier. In tenths of a second.
S10=2 is the Lost carrier hang up delay.
S10 sets the length of time, in tenths of a second, that the modem waits before hanging up after a loss of carrier. This allows for a temporary carrier loss without causing the local modem to disconnect.
The actual interval the modem waits before disconnecting is the value in register S10 minus the value in register S9.
Therefore, the S10 value must be greater than the S9 value or else the modem disconnects before it recognizes the carrier.

Your init string would then be:
S0=2S9=1S10=2
If that doesn't work, try S0=2S9=1S10=1
