AT&T ML series phones are not listed as compatible phones and we cannot guarantee that any of our headsets will be compatible. If you'd like to try installing the headset with that phone you might want to ensure the seller accepts returns for headsets just in case it doesn't work. Please don't hesitate to contact our customer care group at www.plantronics.com/support if you have other questions!
Sorry, there was a problem. Please try again later.I have the model 993 phone which is replaced by the ML17929. Looks very similar to mine. The headset works fine with my phone, it should work with the newer unit. The handset plugs into the headset base and the headset base plugs into the phone base using standard phone jacks and plugs provided.
