Why am I receiving calls from unknown extensions and how do I prevent these calls from happening?

Being that VoIP devices are running over an IP network, we find that these devices become more vulnerable to attacks. Whether it be a denial of service or an attempt to use your services without you even being notified. In cases where you receive phantom calls from random extensions that do not belong to your softswitch, may point to an automated scanner, which seek out gateways in attempt to make free calls as the owners expense.

If this is occurring on your SIP Gateway, it is recommended that do not forward port 5060 on your router, but to use a unconventional SIP port.

If this is occurring on a Grandstream IP phone, users have the ability to deny calls that are not authenticated. On a GXP2130/40/60 you can find the option by navigating the the web interface, clicking on Account X–>SIP Settings–>Security Settings and enabling “Authenticate Incoming invite”

Why does my GXP2130/GXP2140/GXP2160 fail to register to the SIP server?

You should make sure that the phone is connected to the network and the phone is able to obtain an IP address. Secondly, check if the account is set to active by setting the “Account Active” configuration in the Account page of the Web GUI to “Yes”. Additionally, check if the login information and the SIP server are correct. If the SIP server is wrong, the phone cannot contact the SIP sever for registration. If the login information is wrong, the SIP server will reject the registration request of the phone. If all of the above are correct, there may be a problem with NAT traversal. If the GXP2130/GXP2140/GXP2160 is on a LAN and needs to register to a SIP server on a public IP, please enable NAT traversal by selecting the NAT traversal method according to your network environment. If you are unsure, it is recommended to select “Auto” to enable the automatic NAT traversal configuration feature.

I cannot get response from TFTP server when upgrading/provisioning the phone via TFTP. Why?

Also, on the PC running the TFTP server, for windows user, please try with the windows firewall disabled.
For more steps to upgrade via TFTP, please refer to the GXP user manual->”Instructions For Local TFTP Upgrade”.

The GXW4024 will support 24 concurrent calls for all codecs.

How many simultaneous fax calls can the GXW40xx handle?

The GXW40xx series can handle up to two T.38 simultaneous sessions and G.711 Pass-Through on the remaining ports.

If multiple DIDs are bundled with only one sip truck account by service provider, how should I setup the gateway to route calls to different FXS port?

Grandstream GXW IP gateways support call routing based on SIP request URI user ID. This function can help to route calls to different FXS ports within one hunting group.

Settings for incoming calls:

1. Fill the sip truck ID, password, and Name in one FXS port and register it. And then, active its Hunting Group in FXS Ports->Advanced Port Settings.
2. Assign the other FXS ports to the activated hunting group. Then, in Request URI Routing ID field, name them with the additional DIDs bundled in your sip truck.

Settings for outgoing calls: after finishing the step 2 above, go to Profile X->Sip Settings->Basic Settings and set Use Request Routing ID In SIP Headers to Yes.

Once done, gateway will look into the Request URI user ID in the incoming call’s INVITE and route the call to designated FXS Port with matching DID. Also, gateway will replace the From and Contact header in the INVITE for outgoing calls with configured Request URI Routing ID.

What is a dial plan?

The dial-plan is a set of rules that governs the call-routing behavior of a device. When a user dials a sequence of number, the device will refer to the rules in the dial-plan in order to determine how best to connect that call. Please see the GXW410x User Manual available in our resource library for more details on how to configure a dail-plan.

What is a pause in the dial plan and how do I configure this on my GXW410x?

Some offices may require employees to dial ‘9’ then the phone number in order to call out . If the user dials ‘9’ + phone number as one consistent string, the call will not go through and a generic prompt will be generated, e.g. “Your call cannot be completed as dialed. Please check the number and dial again.”. If this is the case, this can easily be resolved by adding a pause in the dial-plan.

To add a pause in the dial plan you will need to configure the “DTMF Dial Pause Between Each Digit(X10ms)”, which can be found under “Dial Plan” tab located in the web-GUI. This is the syntax used to configure the pause: ‘ch1-4:d2p200, d4p400; ch5-8:
d1p100, d3p300’ dx/py means pause 10y-ms after d-th digit is dialed.

For example:
– if 100ms needs to be inserted after dialing the 4th digit, the syntax will be ch1-4:d4p10;
– if 300ms needs to be inserted after dialing the 3rd digit and a second pause of 400ms after the 6th digit the syntax will be: ch1-4:d3p30,d6p40;

Note: The dial plan pause ONLY works in Stage 1 dialing method.

What is the difference between an FXO and an FXS Gateway?

FXO Gateway (GXW410x) – Its allows IP networks to talk to PSTN networks through the gateway by simply connecting analog lines to it. Primarily used to allow remote IP endpoints to be able to use local main office PSTN lines.

FXS Gateway (GXW400x) – It allows your traditional telephone system to function as an IP System by simply connecting analog FXS trunks or analog handsets to the gateway. Primarily used to allow traditional handsets/PABX to be used in an IP environment.

What is the FXS port voltage output in all of it’s stages?

-Idle = 48V
– During a Call = Approximately 7 -9V
– Ringing = Approximately 55Vrms

What should I do if I encounter port hang after a few calls?

Generally, port hang is caused by inability to detect the disconnect signal from the side that hangs up first; usually it is when the PSTN side hangs up first. Follow these steps to fix this problem:

– Call your PSTN carrier and ask what kind of PSTN disconnect signal is used − power disconnect (or current disconnect) or tone disconnect.
– If it is power disconnect (common in most developed countries), ask for the duration of power loss as a disconnect signal.
– If tone disconnect is used, ask for the disconnect tone frequency and cadence, as well as AC Termination impedance.
– Re-configure the GXW410x to reflect the disconnect signal used by the PSTN carrier.
– Power Disconnect: navigate to FXO Lines in the web configuration pages and set Enable Current Disconnect to “Yes”. Make sure the correct duration of power loss is set in Current Disconnect Threshold. Set Enable Tone Disconnect to “No”.
– Tone Disconnect: navigate to FXO Lines in the web configuration pages and set Enable Current Disconnect to “No”. Re-configure the AC Termination Impedance and the disconnect tone frequency and cadence (usually Reorder Tone or Busy Tone under –
Channels in the web configuration pages) to match your PSTN provider.
Reboot the GXW and place some test calls. If the port hang issue is not fixed, contact Grandstream Technical Support.

What’s the difference between one-stage dialing and two-stage dialing?

One stage dialing means the end user hears a dial tone immediately and can place a call.

Two-stage dialing means the end user has to dial twice – once to reach a second dial tone, and again to reach the final destination. In other words, a call traversing from PSTN to VoIP or VoIP to PSTN must go through two dialing stages to reach the intended recipient. For example, a VoIP user will complete the first stage by calling a pre-programmed number (on the GXW410x) and receive the PSTN dial tone in return. The user will then complete the second stage by dialing a PSTN number. The reverse happens for PSTN to VoIP calls.

If one-stage dialing is used, a call from either the VoIP or PSTN side will pass through the gateway to the intended recipient. With one-stage dialing, a PSTN number dialed by a VoIP user will reach the GXW410x, and the GXW410x will immediately dial the call on the PSTN side. For PSTN to VoIP, an incoming PSTN caller will be directly connected with a VoIP extension.

One-stage dialing offers convenient and streamlined dialing, while two-stage dialing offers flexibility and complete access to the VoIP network.

Why can I receive incoming PSTN calls, but outgoing calls (one-stage or two-stage) can’t grab a PSTN line?

You may have compatibility issues with some Verizon, Qwest, or certain other PSTN lines.

The following issues may occur:

One-stage VoIP to PSTN calls cause the line LED to turn on and hang up immediately
Two-stage VoIP to PSTN calls, GXW410x does not pick up a PSTN line
Incoming PSTN calls do not have caller ID information (if caller ID information is available)

To fix the above issues:

Contact Grandstream Support for the latest firmware or visit www.grandstream.com.
Set the following values in the FXO Lines web configuration page:
Enable Current Disconnect to Yes (if the PSTN provider utilizes Current Disconnect).
Current Disconnect Threshold: 300
Min Delay Before Dial PSTN: 750

Why does the GXW410x not pick up incoming PSTN calls using one-stage dialing?

Make sure that you have a valid extension entered in the Unconditional Call Forward to VoIPsetting under the FXO Lines web configuration page. Also, make sure that that extension is reachable by the GXW410x. For example, if using Asterisk™ and you have a SIP account with an ID of 200 but there is no extension 200 in the context the GXW410x resides in, the GXW410x will not be able to reach that SIP user and will not pick up the incoming PSTN call.

How do I connect a PTZ device to work with my GXV3504?

After connecting the PTZ controller to the GXV3504(See User Manual for RS485 connection setup) and configuriring the correct PTZ protocol, you can then set the address code. Most PTZ devices have ON/OFF switches that allow address code configuration. To allow the PTZ control of the GXV3504, it must match the address code of the GXV3504. For example, the address code of the GXV3054 is 1-2-3-4. The user will also set the PTZ address code to 1-2-3-4 using the ON/OFF switches. (Please refer to the PTZ user manual to see how to setup the ON/OFF switch to match address codes.)

How do I disable audio from the camera during a SIP call?

You cannot disable the audio during a SIP call between IP phone and camera. By current design, the IP camera will always have microphone enabled (if supported) during a SIP call. However, you can enable “Disable audio in SIP call” to prevent the camera from outputting your voice to speaker or audio line out. If you wish to view the camera without hearing the audio from the camera’s microphone, you can use the live stream interface of the camera’s web gui or use the RTSP url to stream the camera.

Will the GXV3500 Decoder/Encoder be compatible with third party cameras?

Encode Mode: (Analogue Camera)

Generally, most 3rd party analogue cameras will be digitized to IP Camera when connecting to GXV3500 BNC port at Encode Mode.

Decode Mode: (IP Camera)

Whether GXV3500 can decode the data stream from a 3rd party IP camera is dependent on how the stream was encoded. GXV3500 utilizes the RTSP stream and is capable ONLY H.264 formats decoding (so MJPEG is out of luck). General rule of thumb is if the RTSP stream of 3rd party IP Camera can be viewed by VLC Player (free open source media player software), the GXV3500 will very likely be able to decode the stream, but no guarantee due to the variety of H.264 encoding implementation by different IP Camera vendors.
