APPLICATION DESCRIPTION
IP PBX / SIP SERVER WITH GXW410X
A SIP proxy server such as Asterisk or a SIP registrar server can be deployed with the GXW410x series.
In this environment, the SIP server handles SIP registration and call control and the GXW410x processes
media conversion between IP and PSTN calls.
There are 2 ways to configure GXW410x when using with a SIP Server:
1. With SIP accounts configured on Channels page. In this case, the GXW acts like an endpoint
requesting registration from the SIP Server. Under the Channels webpage you will need to fill in
the information like SIP User ID, Password, etc. Now, when you try to make calls from IP, the call
will be routed to the SIP Server which will forward it to one of the SIP accounts on the GXW410x,
which will then forward it to the PSTN line.
2. Without SIP accounts. In this case, you simply have to configure the SIP Server to perform
forwarding of the SIP INVITE message with the FXO destination number to the gateways IP
Address. The GXW410x will receive the digits and immediately forward them on the FXO lines to
the destination PSTN. Most of the configuration on the Gateway for this case will remain default,
except Stage Method needs to be set to 1, and SIP Server IP Address/DNS name has to be filled.
For incoming calls from the PSTN analog endpoints to the GXW410x, the device will auto forward each
call to a configured IP extension. The SIP Server can then route the call based on its own configuration or
IVR system.

FXS GATEWAY WITH GXW410X [NO SIP SERVER REQUIRED]
Alternatively, the GXW410x can be used without a SIP Server. You can use it in conjunction with a FXS
Gateway (Ex. GXW400x) and still be able to originate and terminate calls from IP to PSTN and vice versa.
All you need to make sure is that the 2 gateways are able to locate each other (they should be on the
same LAN or on Public IP addresses).
In this diagram, configure the SIP Server field to be the IP Address of the other gateway (i.e. configure IP
address of FXS gateway to be SIP Server of GXW410x and vice versa). Please be sure you set SIP
Registration to No.
EXPECTED CALL FLOW: Analog Phone (GXW400x) picks up and dials destination PSTN number. The call
gets routed to the GXW410x which dials out the digit string onto the FXO Lines, thus reaching the
destination PSTN endpoint. On the reverse, incoming calls from PSTN endpoints will be routed
automatically to the FXS Gateway through the GXW410x.

Self-Defined Time Zone
(Yes/No)
Optional Rule:
This parameter controls whether the displayed time will be daylight savings time or
not. If set to “Yes” and the Optional Rule is empty, then the displayed time will be 1
hour ahead of normal time. The “Automatic Daylight Saving Time Rule” shall have the
following syntax: start-time;end-time;saving
Both start-time and end-time have the same syntax:
Month ,day ,weekday ,hour ,minute
month: 1,2,3,..,12 (for Jan, Feb, .., Dec)
day: [+|-]1,2,3,..,31
weekday: 1, 2, 3, .., 7 (for Mon, Tue, .., Sun), or 0 which means the daylight saving
rule is not based on week days but based on the day of the month.
hour: hour (0-23),
minute: minute (0-59)
If “weekday” is 0, it means the date to start or end daylight saving is at exactly the
given date. In that case, the “day” value must not be negative.
If “weekday” is not zero and “day” is positive, then the daylight saving starts on the
first “day”th iteration of the weekday (1st Sunday, 3rd Tuesday etc). If “weekday” us
not zero and “day” is negative, then the daylight saving starts on the last “day”th
iteration of the weekday (last Sunday, 3rd last Tuesday etc). The saving is in the unit
of minutes. The saving time may also be preceded by a negative (-) sign if subtraction
is desired instead of addition. The default value for “Automatic Daylight Saving Time
Rule” shall be set to
“03,11,0,02,00;11,04,0,02,00;60” which is the rule for US.
Examples:
US where daylight saving time is applicable: 03,11,0,02,00;11,4,0,02,00;60
This means the daylight saving time starts from 11th March at 2AM and ends
November 4th at 2AM. The saving is 60 minutes (1hour).
TABLE 8: SETTINGS DEFINITIONS
SETTINGS
General settings
Use NAT IP
NAT IP address used in SIP/SDP message. Default is blank.
STUN Server
IP address or Domain name of the STUN (Simple Traversal of UDP through NATs)
server.
Call Settings
G723 Rate
G723 encoding rate (6.3kbps or 5.3kbps)
Voice Frames per Tx
This field contains the number of voice frames to be transmitted in a single packet.
When setting this value, the user should be aware of the requested packet time (used
in SDP message) as a result of configuring this parameter. This parameter is
associated with the first vocoder in the above vocoder Preference List or the actual

Grandstream Networks, Inc. GXW410x User Manual Page 17 of 32
Firmware Version 1.4.1.5 Last Updated: 5/2014
used payload type negotiated between the 2 conversation parties at run time.
e.g., if the first vocoder is configured as G723 and the “Voice Frames per TX” is set to
be 2, then the “ptime” value in the SDP message of an INVITE request will be 60ms
because each G723 voice frame contains 30ms of audio. Similarly, if this field is set
to be 2 and if the first vocoder chosen is G729 or G711 or G726, then the “ptime”
value in the SDP message of an INVITE request will be 20ms.
If the configured voice frames per TX exceeds the maximum allowed value, the
BudgeTone 200 will use and save the maximum allowed value for the corresponding
first vocoder choice. The maximum value for PCM is 10(x10ms) frames; for G726, it
is 20 (x10ms) frames; for G723, it is 32 (x30ms) frames; for G729/G728, 64 (x10ms)
and 64 (x2.5ms) frames respectively.
Local RTP port
This parameter defines the local RTP-RTCP port pair the GXW410x will listen and
transmit. It is the base RTP port for channel 0. When configured, channel 0 will use
this port _value for RTP and the port_value+1 for its RTCP; channel 1 will use
port_value+2 for RTP and port_value+3 for its RTCP and so on. The default value is
5004.
RTP Loopback
Default value is No. If set to Yes, means no RTP if RTP streams between 2 internal
ports.
Channel Settings
DTMF Method
This parameter specifies the mechanism to transmit DTMF digits. There are7 modes
supported: in audio which means DTMF is combined in audio signal (not very reliable
with low bit-rate codec), via RTP (RFC2833), or via SIP INFO. Multiple DTMF
transmission schemas can be selected.
1 –in-audio
2 –RFC2833
3 –in-audio and RFC2833
4 –SIP Info
5 –in-audio and RFC2833
6 –SIP Info and RFC2833
1. 7 –in-audio, RFC2833, and SIP Info
No Key Entry Timeout
Default is 4 seconds.
Local SIP Listen Port
Default is ch1-8:5060++;. The ++ indicates increments by 2, so port 1 is set at 5060,
port at 5062 and so on. This setting can be used with Round Robin and/or Flexible
setting below to configure different ports to be placed under different Round Robin
groups.
SRTP Mode
Default is disabled for all ports. The user can select to either enable it but not force it
or force it on an individual port basis. When used the communication will be sent
using Secure RTP.
Unconditional Call
Forward to VOIP:
This is an extremely important setting to make sure incoming PSTN calls are picked
up and forwarded to the correct VOIP destination.
User ID - This parameter allows users to configure a User ID or extension number to
be automatically dialed upon FXO line off-hook.
SIP Server - You also need to specify the Profile of the user id configured above (p1
stands for Profile 1, p2 stands for Profile 2 and so on).
SIP Destination Port - Along with the user-id and Profile, you also have the option to
choose the destination port where you would like to send the call. By default it should
be set to ch1-x:5060; (x can be 4 or 8 depending on number of ports).
We can also specify a different destination for each port. For example under User ID
we can type in: ch1:104;ch2:227;ch3-5:501;ch6,7:856.
Under Sip Server we can type in: ch1:p1;ch2-4:p2;ch5:p3
Under Sip Destination Port we can type in: ch1-2:5060;ch2:7080;ch3-8:5066++
T.38 Setting
This setting allows you to make several options related to facsimile.
You can select the method: T.38 or Pass through (G711)
You can select the fax transmission rates (2400/4800/7200/9600/12000/14400bps)
You can enable or disable ECM (Error Checking Mode)
Note:The user can only test the parameters for only one of the PSTN lines at the
same time. In all cases please enter the telephone numbers as if the lines were to

dial each other locally.
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.

SIP Settings
SIP Registration
This parameter controls whether the GXW410x needs to send REGISTER messages
to the SIP Server. The default setting is “Yes”.
Unregister on Reboot
Default is No. If set to yes, the SIP user’s registration information will be cleared on
reboot.
Register Expiration
This parameter allows the user to specify the time frequency (in minutes) for the
GXW410x to refresh its registration with the specified registrar. The default interval is
60 minutes (or 1 hour). The maximum interval is 65535 minutes (about 45 days).
SIP Registration Failure
Retry Wait Time
This parameter is mostly used by Service Providers. It prevents message REGISTER
overload of SIP Server in case of downtime due to maintenance or power failure. By
increasing interval length, common message load is decreased. Interval range is 1 –
3600 seconds.
SIP Transport
User can select UDP or TCP. Please make sure you’re SIP Server or network
environment supports SIP over the selected transport method. Default is UDP.
Session Expiration
Grandstream implemented SIP Session Timer. The session timer extension enables
SIP sessions to be periodically “refreshed” via a SIP request (UPDATE, or re-INVITE.
Once the session interval expires, if there is no refresh via a UPDATE or re-INVITE
message, the session will be terminated. Session Expiration is the time (in seconds)
at which the session is considered timed out, if no successful session refresh
transaction occurs beforehand. The default value is 180 seconds.
Min-SE
The minimum session expiration (in seconds). The default value is 90 seconds.
Caller Request Timer
If selecting “Yes” the phone will use session timer when it makes outbound calls if
remote party supports session timer.
Callee Request Timer
If selecting “Yes” the phone will use session timer when it receives inbound calls with
session timer request.
Force Timer
If selecting “Yes” the phone will use session timer even if the remote party does not
support this feature. Selecting “No” will allow the phone to enable session timer only
when the remote party support this feature. To turn off Session Timer, select “No” for
Caller Request Timer, Callee Request Timer, and Force Timer.
UAC Specify Refresher
As a Caller, select UAC to use the phone as the refresher, or UAS to use the Callee
or proxy server as the refresher.
UAS Specify Refresher
As a Callee, select UAC to use caller or proxy server as the refresher, or UAS to use
the phone as the refresher.
Force INVITE
Session Timer can be refreshed using INVITE method or UPDATE method. Select
“Yes” to use INVITE method to refresh the session timer.
Enable 100rel
The use of the PRACK (Provisional Acknowledgment) method enables reliability to be
offered to SIP provisional responses (1xx series). This is very important if PSTN inter-
networking is to be supported. A user’s request to use reliable provisional responses
is invoked by the 100rel tag which is appended to the value of the required header of
initial signalling messages.
Refer-to uses Target
Contact
Default is NO. If set to YES, then for Attended Transfer, the “Refer-To” header uses
the transferred target’s Contact header information.
INVITE Ring-no-answer
Timeout
In case incoming call has arrived from PSTN to VoIP and INVITE message was
generated by GXW device, the call will be disconnected after preconfigured timeout if
not answered by VoIP extension.
Accept INVITE from Proxy
Only
Default is YES. The device will authenticate and accept only incoming INVITE
messages from the peered SIP server.
Audio Settings
Preferred Vocoder
The GXW410x supports up to 5 different Vocoder types including G.711 A-/U-law,
GSM, G.723.1, G.729A/B. The user can configure Vocoders in a preference list that
will be included with the same preference order in SDP message. The first Vocoder in
this list can be entered by choosing the appropriate option in “Choice 1”. Similarly, the
last Vocoder in this list can be entered by choosing the appropriate option in “Choice
8”.
Call Settings
User ID is Phone Number
If the GXW410x 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.
Early Dial
Default is No. Use only if proxy supports 484 response.
