If a TA9xx does not work for a customer I am not sure what to think because that is an industry standard to me. It is basically as good as it gets and we have deployed 1000s of them. If something is not working I would be pointing a finger at the customer once you know the boxes quite well. Matthew Yaklin Network Engineer FirstLight 359 Corporate Drive ?

I tried using Linksys/Cisco SPA and Grandstream ATA's, then finally put in an Adtran TA904 (2nd gen). The Adtran seemed to give the least number of issues with Lines getting stuck open, Echo, etc. But the (former) customer was still complaining about some issues when they closed up shop. I now need to provide 6 analog lines to hand off to an existing MITEL. Is there an ATA that's better than a TA908 for doing "Acceptable" POTS to a MITEL?
