SIP Proxy Server / Soft Switch Settings
VoIP failure announcement: As soon as the registration to proxy server is failed, the gateway will
drive IVR system to play out failure announcements for the caller.
Bind Proxy Interval for NAT: This function is able to keep the binding that exists when the VoIP
gateway is behind a NAT and SIP Proxy is not able to keep the binding.
Initial Unregister: After rebooting, the gateway is initially unregistered and then it will perform a
general register process.
Support Message Waiting Indication: The system will play a tone to remind users that there are
messages in the SIP Server.
MWI Subscribe Interval: The subscribe interval is for the gateway check of the voice mail.
Supplementary Features
Anonymous Caller ID (CLIR): When enabled, anyone receiving a call from you will not display your
number if they have caller ID.
NOTE: If you register the gateway to a Proxy and you check this option, you may be unable to make a
call. This is due to the fact that the VoIP gateway doesn't send the number for authorization.
