IAXCompat
More than once to bind to multiple addresses, but the first will be the default.
Enable
Nochecksums
Set iaxcompat to yes if you plan to use layered switches or some other scenario which may cause some delay when doing a
lookup in the dialplan. It incurs a small performance hit to enable it. This option cause Asterisk to spawn a separate thread
when it receives an IAX DPREQ (Dialplan Request) instead of blocking while it waits for a response.
Enable Delay
Reject
Disable UDP checksums (if no checksums is set, then no checksums will be calculated/checked on system supporting the
feature)

autokill

connections.
