Grandstream eero Landline Problems

[Dec72]

Fibre installation has been a nightmare! Too long to post but latest issue is no landline!

received Grandstream today but no phone light on it so can’t use phone 

back office looking into but looking at upto 48hrs

any help or advice would be much appreciated!

Glad it all works now.

Working now. Same handset. Reset didn’t work so tried to leave Ethernet out of eero then worked 

[KeithFrench]

Did you try another handset then?

[Dec72]

Latest is that blue phone light is now on and can make and receive calls BUT no sound so although phone rings, and at caller end too, cannot hear each other?

[Dec72]

Thanks, out at present so will try later and let you know. Cheers

Thank you. unless the handset is faulty, something is either blocking the VoIP registration process (hence why the Eero removed from the circuit is a possible solution, in case it blocks it) or the phone line is not set up correctly on the TalkTalk network.

When I know the answer about the handset, I will ask one of the TalkTalk support people on this forum to help you, but I expect that will not be until after this Bank Holiday period.

I’ll try later. It says not registered. I will try another phone but could do without attitude when trying to rectify 

[KeithFrench]

What does the Grandstream documentation say that this telephone light indicates?

Once again, have you tried another phone handset?

[Dec72]

Well I have followed all eero and Grandstream set up guides? Only light not on is the telephone light. I’m not in at present so will try again but not sure what you more you need?!?

[KeithFrench]

It is really a case of finding out what the real cause of the problem is, before working out the solution. Not having access to your network or not being on-site, I can only guess as to a solution.

Can you give any more information like what lights are on the Grandstream & is it that the phone won't register? Have you tried a different phone handset? I am really guessing here because you have provided me with nothing to go on.

Thanks. I did try this last night after reading other threads. I will try again today but is this the only possible solution?

[KeithFrench]

If the phone isn't registered, connect the Grandstream's Ethernet port directly to the ONT in place of the router & then reset it. If it all works, then reconnect the router to the ONT & Grandstream to the router.
