Honor SDP Version
By default, the gateway will honor the session version number in SDP
packets and will only modify the SDP session if the version number
change. Turn this option off to force the gateway to ignore the SDP session
version number and treat all SDP data as new data. This is required for
devices that send non-standard SDP packets (observed with Microsoft
OCS). By default this option is on.
Allow Transfers
Whether or not to globally enable transfers. Choosing 'no' will disable all
transfers (unless enabled in peers or users). Default is enabled.
Allow Promiscuous
Redirects
Whether or not to allow 302 or REDIR to non-local SIP address.
Note that promiscredir when redirects are made to the local system will
cause loops since this gateway is incapable of performing a "hairpin" call.
Max Forwards
Setting for the SIP Max-Forwards header (loop prevention).
Send TRYING on
REGISTER
Send a 100 Trying when the endpoint registers.
Outbound Proxy
A proxy to which the gateway will send all outbound signaling instead of
sending signaling directly to endpoints.

Default T1 Timer
This timer is used primarily in INVITE transactions. The default for Timer
T1 is 500ms or the measured run-trip time between the gateway and the
device if you have qualify=yes for the device.
Call Setup Timer
If a provisional response is not received in this amount of time, the call
will auto-congest. Defaults to 64 times the default T1 timer.
Session Timers
Session-Timers feature operates in the following three modes: originate,
Request and run session-timers always; accept, run session-timers only
when requested by other UA; refuse, do not run session timers in any
case.
