Usually this problem can be solved by changing the maximum speed down to a lower setting until this error does not occur.
If that has no effect try adding &B1 to the init string.
If that does not solve the problem get the user to restrict their modem/TA to a lower BPS rate by using an init string supplied by the manufacturer of the modem.
