I have a little problem with my modem. I have search trough hayes
documentation and come out with nothing. Here's the situation :

- I have a modem pool of 4 modem (OPTIMA modem), with a PBX.
- I disconnect the first modem of the pool for testing if the modem
break or whatever.
- When I'm calling with my Accura 288 on the modem pool, the line Ring 3
times and after it switch on the second modem.

The problem is when the line switch, the ring seems to be to long, so
the Accura respond automatically NO CARRIER.  I tried other brand of
modem such U.S. Robotic, etc and all of their modem work properly with
this line switching.

So a little help would be appreciate!!!
Thanks a lots!
