I use maximiser 5 with a tapi adaptor on my phone - dialout is fine but if I set maxi to handle incoming calls it reads only the last three or four numbers of the callers id. This results in several records coming up. Can anyone tell me if I can get maxi to look for more numbers (7 ideally) when it searches for the caller. It can do this on a manual search so why not with caller id?

This sounds more like a modem/callerID problem than a Maximizer search problem.

See what your modem tells your PC when it rings, by using Hyperterminal connected to your COM port.
