What nmap does is called "fingerprinting". it mostly uses the fact that
when faced with normal behaviours, most stacks behave the same. But when
faced with non-standard behaviour, different stacks would react
differently.

I figure you're actually looking for a more higher-level fingerprinting.
'sip fingerprinting' gives some results. I never tested any. Looking at
a SIP trace for the name of the remote agent (does it happen to be
"Asterisk") is a good start.

But then again, you can try your own. 

* Is there a voicemail menu? If so, what is its structure?
* Are there any conference rooms suggested? Look familiar?
* The default installation of FreePBX will respond to a misdialed call
  with a friendly 'Your call cannot be connected' IIRC. Though this can
  be configured off.
