system speed call dialing timer threshold

[jertson]

i just upgraded the system to CS1000E Rls. 7.50Q from old software OPT 11C system Rls. 22.46, my question is when they are dialing the
system speedcall list, the dialtone appears to be longer like less than 3 seconds, compare to their old software which appear to be shorter like 2 seconds only.

is there a way to adjust this timer for system speedcall dialing

any suggestions please
