No. In our test we understand by call the following messages:
1. INVITE remote_party
2. 100 Trying
3. 180 Ringing
4. 200 Ok
5. ACK
6. BYE
7. 200 Ok
8. ACK

Also the speed depends on whether you are using stateless (faster) or
statefull forwarding and in general the contents of your cfg script.

We tested at some point ser on an iPaq pda (intel strongarm 110 cpu) and
it did over 100 cps in statefull mode (IIRC arround 150).
So I assume your PC can do much more than 100cps (unless you don't exec
 from the script some very time consuming application).

A dual Athlon MP2000+ does 4800-4900cps and probably arround 6000-7000
in stateless mode.
