Basic Installation and SettingsConnect the network cable to the Network Port on the back of the phone and connect the other end to the Internet. If the network is functional, a small blue icon will be displayed on the upper right-hand corner of the LCD screen. If the icon is orangeit means that the phone failed to connect to the network. The phone may fail to connect to the network if the network cable is not connected properly. If this is the case, please try reconnecting or replacing the network cable. It is recommended to use the network cable in the GXV package, as it is fully compatible with the phone. Please select the NAT traversal method according to your network environment. There is also an easy way to check if the phone needs NAT traversal or not. After the phone is installed, dial 0 on the phone. If you are able to see a welcome video with a rotating globe on the LCD screen then there is no problem with the NAT traversal. If you do not see this, this means that external UDP packets cannot be forwarded to this phone. Please refer to the figure below while installing your GXV Only use the power adapter and network cable in the package, using a different network cable may lead to the failure of obtaining an IP address. Connect the longer end of the handset cord to the back of the phone and the other end to the handset. The GXV has two positions for the stand on the back of the phone; each position supports a different angle. It also has two slots on the back of the phone for wall mounting. For example, you can connect a USB flash drive to save captured pictures or use a USB keyboard or mouse for the built-in web browser. Therefore, there could be situations where the phone has lost its IP address but the monitor still shows the old IP address or vice versa. However, the IP address shown on the [Info] page is updated dynamically. Talk into the handset or the on-hook phone. If you can clearly hear your own voice, the audio capability on the GXV is fully-functional. After the GXV is installed; you should do a diagnostic to make sure that the keys are functional.
I have 2 extensions out of 18 in FreePBX that will not register with the server. When the extensions were created over a year ago they worked fine. We use Grandstream VoIP phones and are a small office. Both phones are GPX All phones and FreePBX server are on the same switch. This last step has me questioning why this extension will not register while I have other Grandstream phone that register just fine. What SIP driver are you using? What port is the sip driver bound to? To which port are your phones connecting? Possibly, the SYN requests are for fetching a config file and failing because of firewall rules, wrong port, etc. In this case, the idle screen would not show the account name would either show Grandstream or be blank. Where do I find the SIP driver? The SIP port is There you can check which driver is enabled and to which port it is bound. Configuration is via the web interface. Provisioning is done by uploading the. This is set to default The Bind Address is 0. There could be requests to e. If a domain name, do you see the DNS lookups in your Wireshark trace, and are they successful? If an IP address, is it correct? Can you ping the phone from a shell prompt on the PBX? I wanted to verify that the OS firewall was not the issue. The Responsive Firewall was disabled. This rejects incoming connections. When you enabled responsive, it allowed a limited number of registration attempts from hosts that were otherwise denied access, which probably means the FreePBX firewall is misconfigured.
