The "Obtaining IP Address/Network unavailable" error is a LOCAL error and not related to the service provider. It means there is an issue on-site that is preventing the phone to work within the LOCAL network.


What Does the "Obtaining IP Address/Network unavailable" Error Mean?

When a VoIP phone displays the "Obtaining IP address" error, it indicates that the device is struggling to acquire an IP address from the LOCAL network. An IP address is crucial for any device to communicate on a network, as it acts as a unique identifier. Without an IP address, the VoIP phone cannot connect to the internet or the local network, rendering it unable to make or receive calls.



Common Causes of the "Obtaining IP Address/Network unavailable" Error

Several factors can lead to the "Obtaining IP address" error on a VoIP phone. Understanding these causes is the first step toward resolving the issue.

  1. DHCP Server Issues/static IP: A common cause is a problem with the DHCP/static IP controller (usually a router), which is responsible for assigning IP addresses to devices on the network. If the DHCP server is down or misconfigured, the VoIP phone will not receive an IP address.
  2. Network Connectivity Problems: Issues with the network connection, such as a faulty Ethernet cable, incorrect Wi-Fi settings, or a malfunctioning network switch, can prevent the VoIP phone from communicating with the DHCP server.
  3. IP Address Conflicts: An IP address conflict occurs when two devices on the same network are assigned the same IP address. This can prevent the VoIP phone from obtaining a unique IP address.
  4. Firmware or Software Glitches: Outdated or corrupted firmware on the VoIP phone can interfere with its ability to obtain an IP address.
  5. Network Configuration Errors: Incorrect network settings on the VoIP phone, such as the wrong IP configuration or subnet mask, can cause this error.


How to Resolve the "Obtaining IP Address/Network unavailable" Error

Here are some steps to troubleshoot and resolve the "Obtaining IP address" error on a VoIP phone:

  1. Restart the VoIP Phone: Sometimes, simply restarting the device can resolve temporary glitches.
  2. Check Network Connectivity: Ensure that the Ethernet cable is properly connected, or if using Wi-Fi, verify that the phone is connected to the correct network with the right credentials.
  3. Reboot the DHCP Server: Restart the router or the DHCP server to refresh the network settings and reassign IP addresses.
  4. Update Firmware: Check for and install any firmware updates for the VoIP phone to ensure it is running the latest software.
  5. Check for IP Conflicts: Ensure that no other device on the network has the same IP address as the VoIP phone.
  6. Manually Assign an IP Address: If the DHCP server is unreliable, consider assigning a static IP address to the VoIP phone.


IMPORTANT: If one phone is registered and online, it is probably a cabling issue. Check for faulty ethernet points and cable loops.
