hi Whatis, whether you have sent a request to TP-LINK support? i think maybe they have had a solution, but the new firmware need more time to be released. can we ask them to give us a beta firmware?

hi erichalfb, when you used the Netcomm modem, the dial tone of VOIP and PSTN are different??? i think it's a good feature,, also the daylight function,, tplink should consider to support these good...

hope they can give out a perfect solution soon.. :D
