Here is my setup,
Polycom Soundstation 2w connected to a Cisco phone voip adapter. This is so that the analog line from the Soundstation 2w is translated to VOIP and is able to get a number from our server. The phone works great until we have to use it to call and have a conference call with someone. The problem occurs when we try and enter the PIN number for get in the conference call. It keeps doing this echo thing and it shows as though we entered the number once on the dial pad but it keeps saying we entered the PIN incorrectly, furthermore we are able to join the conference with a simple deskphone. But the Wireless conference phone does not work. Has anyone else had this problem and fixed it? We have tried updating the software and we have tried typing very slow, and very fast. Nothing seems to work. When this occurs the Base of the Soundstation 2W is about 5 feet away.

The same or similar issues has been brought up a few times already in the communities PSTN section and can be found via the search functionality => here <=
The double DTMF issue is caused by the Cisco adapter as it picks up the DTMF from the phone and sends it again.
Simply connecting another analog phone to the same adapter would show the same behavior. The phone itself works as you would not be able to dial the number itself in the first place.

I tried that and a none, wireless phone does not have the same problem even when I plugged it directly into the cisco device. There is no double enter of the numbers. I can dial 123-456-4567 But when I enter the PIN 4567 it goes in as 445667
you could try to mute the call before you add the requested PIN code and then unmute.
