Hello,
After upgrading my package from fast broadband and phone calls (copper line) to Full Fibre 500 with VOIP, while retaining my existing phone number, while my fibre connection is working perfectly I have encountered a problem with the VOIP landline functionality. Specifically, I am unable to make outbound calls or receive incoming calls, despite the presence of a dialing tone. Upon attempting calls, both outbound and inbound, I am consistently met with a continuous beep-beep noise.
It is worth noting that upon receiving the TalkTalk equipment, I did not receive a Grandstream digital voice adaptor. Consequently, my son bought me one from eBay and diligently configured it as per the provided instructions on the TalkTalk website. However, despite our efforts, only two blue LED lights illuminate, signifying internet connectivity and power. Notably, during attempted calls, the blue LED indicator for the phone flashes intermittently and ceases upon call termination.
In our troubleshooting attempts, my son has executed a factory reset on the Digital Voice Adaptor and even attempted a direct connection to the ONT installed by Openreach. Also, I have even tried the digital voice app Regrettably, these efforts have not yielded a resolution.
Your expertise and guidance in rectifying this matter would be greatly appreciated.
