Sounds dreadful. Here, easily, it takes about 3 seconds.

What modem is it?

As a stopgap you could include the "NO CARRIER" in your chat script
expect strings before the AT, which might bring the time down to the
time your modem takes to emit the string, which shouldn't be much.
Uhm, actually, could be the following, too.
The problem seems to be your chat script is exiting before NO CARRIER
is completely finished being sent. Then, the new one picks it up and
interprets it. I changed my ABORT 'CARRIER' line to after dialing
so this doesn't happen to me anymore.
Try it out.
