Progress Inband
If we should generate in-band ringing.
Always use ‘never’ to never use in-band signaling, even in cases where
some buggy devices might not render it.
Valid values: yes, no, never.
Default: never
Allow Overlap
Dialing
Whether or not the Remote-Party-ID header should be trusted.
Append
user=phone to URI
Whether or not to add ‘;user=phone’ to UPIs that contain a valid phone
number.
Add Q.850 Reason
Headers
Whether or not to add Reason header and to use it if is available.
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
changes. 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.
