Archer VX1800v_V1

Phenomenon:

Hi VX1800v users, we have received feedback that when using the Telephony (VoIP) feature on the Archer VX1800v (specifically with Australian ISPs), you may experience the following symptoms regarding incoming calls:

• The phone rings only once/twice and then stops ringing.
• Despite the phone stopping to ring, the line is not disconnected and the caller may still hear the ringing tone.
• Picking up the handset allows the conversation to proceed normally.

Available Solution:

Our relevant departments have identified the cause and provided beta firmware. Please manually download the beta firmware and test whether the VoIP function works as expected.

Note: 

• Please be sure you have read the Beta Test Agreement before upgrading the beta firmware!
• For the sake of insurance, it's always recommended to save a copy of the modem's Backup Config file before upgrading.
• You may follow the guide to upgrade the firmware of your modem, How to upgrade firmware of TP-Link xDSL Modem Router.

If the above beta firmware does not improve the VoIP functionality of your Archer VX1800v, ​​or if you have other modem models experiencing the same anomaly, please provide specific information, including but not limited to:

• The specific model, firmware, and hardware version.
• ISP information.
• A detailed description of the abnormal behavior, including screenshots of the error message.
