LDAP or LAPD?

If LAPD, then it would be best to avoid that protocol.  It's another
level 2 protocol chewing up CPU cycles.  Putting a socket on the south
end of Q.931 is more appealing.

I don't think an Asterisk box can generate enough calls to cause sockets
related performance penalties.  Five packets per phone call.  What's the
max call rate an Asterisk box can support?
