Mike Lunn: /* Grandstream GXW 410X Gateway and HT841 FXO FXS Gateway */

== Grandstream GXW 410X Gateway and HT841 FXO FXS Gateway ==

If you are installing and HT841 gateway, you will program it the same as the GXW 410X below with 2 added settings.

# In the SIP provider page you will change the Port to Custom and go to the fxo profile and look to see what port is manually.
# In the HT841 you will wet the FXO Port settings for the Hunt Group to port 1. Active, and the rest of the ports to 1.

Description

The following configuration guide is for use setting up the Grandstream GXW410X gateways with analog circuits.

NOTE: This guide is based upon the most current software from Grandstream. However if you have older firmware this is a link to the older guide which documents and covers the older firmware.  The 4104 and 4108 use the exact same firmware as each other and have the same interface.

[http://wiki.ipitomy.com/images/5/57/Tech_Bulletin_2011-008_Grandstream_Configuration_Guide.pdf http://wiki.ipitomy.com/images/5/57/Tech_Bulletin_2011-008_Grandstream_Configuration_Guide.pdf]

[[File:Gstream1.JPG|File:Gstream1.JPG]]

=== Procedure—Connections ===

1. Connect each analog circuit to the desired FXO port, as above

2. Connect the Grandstream WAN port to an available LAN port of the network switch/router being used on site.

[[File:Gstream2.JPG|File:Gstream2.JPG]]

=== Procedure—Power Up and Login ===

1. Power up the unit and identify its assigned IP address. (Typically assigned from the DCHP server of the host router.)

2. Use your browser to access the Grandstream by inputting the IP Address assigned to it. The IP Address assigned by your router via DHCP can be discovered several ways – the easiest of which is likely by accessing the router’s connected devices page and finding it listed there.

3. When the Grandstream page is accessed, input the password (admin at default) and navigate to the pages below making the changes as defined.

=== IMPORTANT: Procedure Line Setup ===

On first login to the Grandstream, you will be brought to the following page.

[[File:GrandstreamCPT.jpg|File:GrandstreamCPT.jpg]]

In ALL new installs once you have the device on the Network and lines connected, you should run each of these tests. The first is for Call quality and is MOST important. As this test matches line impedance which if it is in variance can cause echo and poor calls. The second allows the device to learn Call Progress Tones (CPT) and is also very important so that the Unit can learn disconnect and busy tones on the lines. NOTE: The Grandstream can learn a Disconnect Supervision Current drop and a busy tone for disconnect. Lastly is the test for CID. This is also important and additionally can detect CID presence on the line. For proper performance of the Grandstream Device these tests SHOULD NOT be skipped.

NOTE: These tests should be performed at the site and with the lines that the unit is intended to be in service upon.

=== Procedure—Configuration ===

1. Navigate to the Networks Basic Setting page and input the data as in the example.

[[File:SIP3.jpg|File:SIP3.jpg]] 2. Assign a Static IP Address. The device must be found by the IPBX regardless of incidental changes and network adjustments. For this reason its best to change the IP Address to Static and assign an address that is out of range of those assigned for DCHP subscription. (E.g. if the router will assign DCHP Addresses from 192.168.1.1 ~ 192.168.1.50 you should select an IP Address out of this range ...192.168.1.200 would work unless it is being used elsewhere.) 3. Use the other information provided by the DCHP assignment process in the remaining data fields; Subnet is usually 255.255.255.0. The Default Router Address must be that of the router the same one that assigns DCHP IP Addresses. DNS should also be the router since it will direct traffic. 4. Click the save button. This saves information on this page before moving on. 5. Navigate to the FXO Lines page. Then Select Dialing on the left. 6. Change the Stage Method(1/2) Ch1-4:1;

[[File:Gxw410x stagemethod.PNG|File:Gxw410x stagemethod.PNG]]

 7. Navigate to Settings and then select Channels Settings on the left. Program DTMF Methods to ch1-4:2;. Program the Unconditional Call Forward to VOIP: to include the DID (Direct Inward Dial) number(s) that are to be routed.This routing is accomplished by Profiles 1, 2 & 3. Usually only one is necessary.This data field is the routing of the calls that are received on this FXO circuit (It is recomended to use our example on this line which is ch1:1111;ch2:2222;ch3:3333;ch4:4444; This will create "virtual DIDs" of 1111, 2222, etc, that allow you to enter DIDs in the PBX under the SIP Provider so you can route calls to different locations based on what line they came in on.  We have programmed the Grandstream to route calls that have been received to the SIP Server using Profile 1.

[[File:Gstream3.JPG|File:Gstream3.JPG]]

8.Click the save button.

=== Procedure—Configuration Profile ===

[[File:SIP.jpg|File:SIP.jpg]]

1. Navigate to the Accounts=>Account 1=>General Settings page. 2. Here the SIP Server must be programmed. Set this to be the IP Address of the IPBX. In our example, the address is 192.168.2.153. 3. Also be sure that the SIP Registration field is set to No. 4.Click the save button. 5.The Grandstream configuration is now complete. However if you wish to make changes to the dial plan allowed digits you must also program that information. Note: At default the Grandstream allows only digits 0-9 to be sent to the connected PSTN circuit. If you want to use PSTN features like call forward you will need to change the Outgoing Dial Plan field to; {x+ | [x*]+}

[[File:Sip2.jpg|File:Sip2.jpg]] to be able to send a * to outside IVR's 6. When programming is complete in the Grandstream, click submit will commit the changes saved thus far to memory and make them operational. Continue to Procedure Configuring the IPitomy IP PBX

[[File:Gstream5.JPG|File:Gstream5.JPG]]

=== Procedure—Configuring the IPitomy IP PBX for Grandstream GXW 410x ===

1.In the IPitomy IPBX set the fields as you see them below... using the Static IP Address assigned to the Procedure—Configuration step previously completed.. (In our example we assigned the Grandstream an IP Address of 192.168.2.9. This becomes the ―Host)

2. Click “Save Changes”

3. Then click on theApply Changes (upper right) to make these settings operational in the Ipitomy IPBX.

4.Test the operation. Make a call into each of the Grandstream ports that have circuits and assure that they are being routed as defined in Call Routing—Incoming.

 5.Test the operation. Make a call at an Ipitomy extension using a calling pattern as defined in Call Routing Outgoing to assure that the call that should be placed over the Grandstream ports are placed.

=== Procedure—Configuring Optional Outbound Routing Methods ===

The Grandstream allows for two methods of outbound dialing at the same time.

Round-Robin (Linear Hunt)

 If you add the trunk to an outbound route in the PBX, the Grandstream will follow the Round-Robin rules, which are found on the Channels page. By default it will start at Line

1, and move on until it finds an available channel to dial outbound.If you add the trunk to an outbound route and configure Prefix Digits to 99X where X is the port on the Grandstream you wish to use when placing this call (e.g. 991 is line 1). By doing this you can configure the calls to route out a particular line, or a different order if you add the trunk multiple times and prefix accordingly (992, 994, 991, 993, etc). The code of 99 can be changed on the Channels page in the Grandstream.

1. Navigate to the Channels page

2. Go to the Port Scheduling Schema (Voip->PSTN) section and input the code or codes that you wish (99x)

=== Procedure—Configure Multiple Line Groups on Single Grandstream ===

'''1 -''' In order to put the lines into separate outbound groups you will need to configure each round robin group under FXO Lines => Dialing. In this example lines 1-3 are in the first group and line 4 is standalone.

[[File:GS RR Separate.PNG|File:GS RR Separate.PNG]]

'''2 -''' After setting up the round robin groups you now have to configure the local SIP port for the groups. In this example channels 1-3 are using 5060 and incrementing by 2 (this is default behavior for multiple channels in a group, any call sent to 5060 will use the first available line in the group), channel 4 is alone listening on port 5160.

[[File:GS RR Ports.PNG]]

'''3 -''' After configuring the local SIP port you now need to configure the account SIP User ID, this will allow the PBX to differentiate between each line group on incoming calls. Lines 1-3 will give a user ID of 0001, and line 4 will give a user ID of 0002.

[[File:GS RR Account.PNG]]

'''4 -''' On the PBX side we will need to create two trunks, both pointing to the same IP address of the Grandstream, but each will have a different user. '''Be absolutely certain you configure the trunk with Insecure = No''', this setting will tell the PBX to consider the user when taking the call. Notice that on the 2nd trunk we've added the correct port number for line 4 and the correct User associated with line 4. These two settings are what make the 2nd trunk use line 4, the first trunk is using the default port of 5060 and therefore only needs the user to distinguish incoming calls.

[[File:PBX RR Trunk.PNG]]

Outgoing calls will now be sent to port 5060 on the Grandstream to use lines 1-3, calls sent to 5160 will use line 4. Incoming calls on lines 1-3 will hit the PBX with the user of 0001 which will select the first trunk, incoming calls on line 4 will hit the PBX with user 0002 selecting the 2nd trunk.

== Remote Grandstream Configuration ==

In order to get a Grandstream 410x working as a remote device, you must make a few changes from the standard, local configuration. Use this guide in conjunction with the standard guide.

=== Grandstream Changes ===

#On the Accounts=>Account X=>SIP Settings page, set SIP Registration to YES
#Under the User Accounts page, configure one channel with login credentials:
#Set the SIP server in the Profile to the PBX Public IP.

[[File:Gxw410x remotesettings.PNG|File:Gxw410x remotesettings.PNG]]

=== PBX SIP Provider Changes ===

#Instead of entering an IP address for Host, set to “dynamic”
#Set Register and Authentication to YES
#Set Username and Name to the value entered as SIP User ID and Authenticate ID in the grandstream
#Set Secret to the value entered for Authen Password in the grandstream

Note: If the grandstream is not the only device at the remote site, then all remote SIP devices will need to have Can Reinvite set to YES.

== Troubleshooting ==

=== Procedure—Troubleshooting—Outbound Dialing ===

If you having trouble dialing outbound make the following changes on the FXO Lines page:

 1. Tweak the Disconnect Threshold from 100 to 300ms.

 2. Tweak the Minimum Delay Before Dialing Out from 500 to 750ms.

=== Procedure—Troubleshooting—Call Quality ===

 If you are having call quality issues try the following changes on the Channels page:

 1.Set Silence Suppression from YES to NO.

 2. Set Echo Cancellation from YES to NO

=== Procedure—Troubleshooting—Call Volume ===

 If you are having issue with call volume try the following changes on the Channels page:

 1.Increase/Decrease Tx to PSTN Audio Gain by increments of 3 for issues with external party volume.

 2. Increase/Decrease Rx from PSTN Audio Gain by increments of 3 for issues with internal party volume

''' Procedure—Troubleshooting—Call Buzzing Noise'''

If you are having issues with a buzz heard prior to a Menu prompt; try upgrading the Grandstream firmware:

1. Navigate to Advanced Settings page

2. Ensure HTTP is selected for the method to upgrade

3. Set Firmware Server Path: to firmware.grandstream.com

4. Set Automatic Upgrade to YES

5. Set Allow DHCP Option 66 to override server to No Click Update at the bottom of the page

6. Click Reboot The upgrade may take as long as 20min when done through the internet, so allow plenty of time for this. While upgrading the LED will blink. When the LED returns to normal, the device has completed its upgrade

=== Procedure—Troubleshooting—Restore Factory Default ===

To Restore Factory Defaults:

1. While powered up, hold the recessed Reset button in for 7+ seconds

'''[[File:Gstream6.JPG|File:Gstream6.JPG]] '''

'''Procedure Setup of QOS'''

1. Access the IP of the Grandstream.

2. Navigate in the Grandstream Web Admin to Networks – Advanced Settings

3. Set the Layer 3 Diff Serv Value to 24 Which is CS3 or in Binary 011000

4. Submit your changes and reboot
