Outbound Proxy
This field contains the URI string or the IP address (and port, if different from
5060) of the outbound proxy. If there is no outbound proxy, this field SHOULD
be blank. If not blank, all outgoing requests are sent to this outbound proxy.
SIP User ID
This field contains the user part of the SIP address for this phone. e.g., if the
SIP address is sip:my_user_id@my_provider.com, then the SIP User ID is:
my_user_id.
Do NOT include the preceding “sip:” scheme or the host portion of the SIP
address in this field.

SIP service subscriber’s Authenticate ID. Auth ID can be identical to the SIP
User ID.

If the HT–496 has an assigned PSTN telephone number, this field should be
set to “Yes”. Otherwise, set it to “No”.
If “Yes” is set, a “user=phone” parameter will be attached to the “From” header
in SIP request.
SIP Registration
Controls whether the HT–496 needs to send REGISTER messages to the
proxy server. The default setting is Yes.

Default is No. f set to Yes, the SIP user’s registration information will be

The default value for FXS port 1 is 5004. The default value for FXS port 2 is
5008.
