For the AC Impedance Test we only need to select the line to be tested by clicking on
the AC impedance box corresponding to that line, telephone numbers are optional.
Remember that the AC impedance test is usually used to reduce the echo that might
be present in the line.
For the CPT test (call progress tones) we will test current disconnect as well. You will
need 2 telephone numbers to perform the test. You can only perform the test on one
line (row) at the same time and it will be the one that has the box checked for testing.
This tested line will use another line connected to the gateway to perform the test by
calling into it, this is why you will have to enter the telephone number for a second
line to help with the test.
For CID detection you will need 2 telephone numbers to perform the test. You can
only perform the test on one line (row) at the same time and it will be the one that has
the box checked for testing. This tested line will use another line connected to the
gateway to perform the test by calling into it, this is why you will have to enter the
telephone number for a second line to help with the test.
To perform the test, please select the line you want to test and the desired test to be
performed. Enter the information for this line as well as a second line if necessary.
Then click on the update button and then reboot. Log back in and now you should
see the information for the line selected as well as the check box already marked
already there. Go ahead and start the test now, please wait a few minutes until the
test is done.
Notes:
It is not required to enter a telephone number when testing for impedance, as the
system does not place any actual calls for the test.
If you log into the Web Interface while the test is running will not interrupt the process.
TABLE 9: ACCOUNTS DEFINITIONS
ACCOUNTS
General Settings
Account Active When set to Yes the SIP Profile is activated.
Account Name A name to identify a Profile.
SIP Server SIP Server’s IP address or Domain name provided by VoIP service provider.
Outbound Proxy IP address or Domain name of Outbound Proxy, or Media Gateway, or Session
Border Controller. Used by GXW410x for firewall or NAT penetration in different
network environments. If symmetric NAT is detected, STUN will not work and ONLY
outbound proxy can correct the problem.
Networks Settings
Use DNS SRV: Default is No. If set to Yes the client will use DNS SRV to look up server.
NAT Traversal This parameter defines whether the GXW410x NAT traversal mechanism will be
activated or not. If activated (by choosing “Yes”) and a STUN server is also specified,
then the GXW410x will behave according to the STUN client specification. Under this
mode, the embedded STUN client inside the GXW410x will attempt to detect if and
what type of firewall/NAT it is sitting behind through communication with the specified
STUN server. If the detected NAT is a Full Cone, Restricted Cone, or a Port-
Restricted Cone, the GXW410x will attempt to use its mapped public IP address and
port in all of
its SIP and SDP messages. If the NAT Traversal field is set to “Yes” with
no specified STUN server, the GXW410x will periodically (every 20 seconds or so)
send a blank UDP packet (with no payload data) to the SIP server to keep the “hole”
on the NAT open.
Proxy-Require SIP Extension to notify SIP server that the unit is behind the NAT/Firewall.
Use OBP in Route Utilizes outbound proxy in route.
