DNS Mode
One from the 3 modes available for “DNS Mode” configuration:
-A Record (for resolving IP Address of target according to domain name)
-SRV (DNS SRV resource records indicates how to find services for various protocols)
-NAPTR/SRV (Naming Authority Pointer according to RFC 2915)
One mode can be chosen for the client to look up server.
The default value is “A Record”
Tel URI
The default setting is “Disabled”. If the phone has an assigned PSTN
Number, this field should be set to “User=Phone” then a
“User=Phone” parameter will be attached to the “From header” in the SIP
request to indicate the E.164 number. If server supports TEL URI format, then this option
needs to be selected.
SIP Registration
This parameter controls whether the GXW42XX needs to send REGISTER messages to
the proxy server. The default setting is “Yes”.
Unregister on Reboot Default is No. If set to “Yes”, the SIP user’s registration information is cleared on reboot.
Outgoing Call without
Registration
Default is No. If set to “Yes,” user can place outgoing calls even when not registered (if
allowed by Internet Telephone Service Provider) but is unable to receive incoming calls.
Any port, member of a Hunting Group that is not registered with a SIP account, will be
able to place outbound calls using the SIP credentials of the primary Hunting Group port.
For example: Port 1, 3 and 5 are members of the same Hunting Group. Port 1 is
registered with a SIP account. Ports 3 and 5 are not registered. Ports 3 and 5 will be
able to place outbound calls using the SIP account of port 1, even if Outgoing Call
without Registration is set to No
