You need your Installer to Tell ESI to FIX it( it can be done) actually Your Installer may have access to the field that needs to be adjusted ( fine tuned) it is a default value in ALL Esi systems and it usually works very well

Tell your installer to try F16-6 caller ID Gain, depending upon the software of the system, He may be able to get it thru the phone try a value of 11000. tell him to look at the value that is curently there(default is 20000)


I can see the light at the end of the tunnel..
