Guys, it's now 1 month since I PM'd you the details you requested and I'm not hearing back from you!   Can you please respond to my issue?   Thanks...Dale ... View more

Hey Shane,   it's almost 1 month since I PM'd you the details you requested and I haven't heard back from you. Uniden claim on their website that ALL their cordless phones are NBN compatible. My mother's cordless phone is the DECT 2035+1 model. I may have got this model number wrong previously but in any case, Uniden say it IS indeed NBN compatible.   Do you have any more information from TP-Link concerning the Archer VR1600V router and whether it correctly responds on receiving the BYE data packet (when the remote party hangs up) and correctly sends the CPC Disconnect Signal to the attached analogue cordless phone?   Cheers...Dale     ...

Hi BasilDV,   thanks for your kind reply and for that Whirlpool Forum link, all of which which I read with interest.   However most of the discussion in that link, of many years ago, missed the fact that the PSTN exchanges do indeed send a call termination signal (CPC Disconnect Signal) when the remote party hangs up.   They do this by simply sending a polarity reversal of the line voltage or a zero volts line voltage after about 60-90 seconds, regardless of who initiated the call. This allows ALL ELECTRONIC PHONES to hang up automatically.   Obviously the old electro-mechanical phones could not hang up automatically as the handset needed to be physically replaced back on the hook switch in order to break the contacts. But certainly all electronic phones could respond to this CPC Disconnect Signal correctly.   So clearly with the NBN, which uses the SIP protocol for all phone calls; there would indeed by a BYE data packet sent to the local gateway/router when the remote phone hangs up.   So now my question is, when the Archer VR1600V receives this BYE data packet, why it is NOT sending the CPC Disconnect Signal to the analog phone connected to it's phone port, in order to force any electronic cordless phone to hang up? This is clearly NOT happening and I suspect it might be an oversight in the router firmware.   Could you please follow this up with TP-Link, who make the Archer VR1600V, and ask them if their hardware is capable of sending this CPC Disconnect Signal and if there current firmware correctly interprets the BYE data packet in order to send the CPC Disconnect Signal?   This is obviously a serious issue for many elderly people.   Thanks...Dale BARBER ...
