Hi Basil, I see that you have also replied more recently (3Jan23) on another thread (Title "Need VOIP settings - TP-Link Archer VR2100V" started by Vickitrew on 30-09-2022 06:00 PM which was an identical problem to mine) so it seems sensible for me to be replying to that, too.  Here is what you posted on 3Jan23:... "... Be advised that the bundled VoIP service will only work with a TPG provided modem/router with dedicated firmware for our service... If you are using a third party device, then it will not work even though you've configured the SIP settings...If you really need the VoIP service, then you have the option to use the TPG provided modem/router and use the new device as an access point."   We really don't want to do this, as we have since installed very expensive hardware connected to our new 2100 modem to overcome the transmission problems previously inherent in the double brick walls in the centre of our house, and this works now!   The critical information for our plan is at https://www.tpg.com.au/forms/FTTN_SL.pdf.  There appears to be no restriction such as what you stated, viz. "only work with a TPG provided modem/router with dedicated firmware for our service".  And we pay $10 per month for the VoIP component of our Plan.  Furthermore, "the full terms and conditions for this service are available at www.tpg.com.au/terms_conditions" but there was still no reference.   Can Tpg please find some way for us to use our new TP-Link Archer VR2100v modem for VoIP?  I am happy to pay for a technician to add the dedicated firmware to our new modem, at reasonable cost, if that is really necessary.  We are in the eastern suburbs of Adelaide. ...

Hi vickietrew, I have exactly the same problem.  I used to be able to make and receive VOIP calls but can't now, since we installed a new TP-Link Archer VR2100v modem.   We paid for installing our new modem, and for configuring it and all our dependent devices for Tpg.  And we disposed of the old modem Tpg had supplied into electronic garbage.  The VOIP handset gave a dial tone so I assumed it worked.   But now that I have found out that VOIP didn't work beyond the dial tone, I have logged in to our new modem and checked that all the configuration details for VOIP appear to  be correct, and I have plugged the handset's cable in to the modem's Line 1, and rebooted it.  Still no VOIP.   I called the technician out again and he said I needed more info from Tpg.  But when I rang Tpg Help they said they couldn't help me with a modem they didn't supply.   I find this unbelievable, and unacceptable.  But currently I am stuck, am waiting for a response to my Private Message to a moderator, and meanwhile wonder what happened to you and your identical problem. ...

Sorry to be a nuisance but I am trying to send a Private Message and have to do a Post before I can do that (apparently I have to be a "Level 2" registered user).  Hope this "Reply" of mine does that for me. ... View more
