Anybody know any tricks to get these NEC DTL 8R-1 cordless phones to work correctly on the SL2100
I know there’s a bulletin on adjusting the transmit and receive but it doesn’t seem to work very well
lots of complaints it’s too bad everybody wants a cordless phone they don’t work very well anybody work at those IP dect phones at all

I like the older version cordless phones are much easier to use

Are they on POTS lines? If so make sure you do the line calibration in 90-68-01 & reset the system. Hope that helps...

This appears to be an issue on the SL2100 I brought the phone back to my office and it seems to be OK on my SL1100

I have a new SL2100 that I tried it on and got the same results really bad echo

I saw the tech bulletin with the adjustments for the audio but the settings didn't seem to work
