Not quite :/

The closest thing is app_groupcount (available in CVS HEAD)

This allows you to restrict outbound calls, but incoming calls are 
harder to restrict.

There is also an incominglimit & outgoinglimit for sip.conf
http://voip-info.org/wiki-Asterisk+sip+incominglimit

It says there that 'outgoinglimit' is currently disabled in the source 
code, but I don't see this when I look at the code.
It does say that app_groupcount is to replace this completely.


I would really like to see a 'total calls' limit for my remote servers 
(so bandwidth-limited that this will often be just 1!)
Currently I can only set a maximum of 1 IAX call in each direction 
(since I control both ends of the trunk).
I can't get it down to 1 in total...
