Hello hercross,
welcome to the Polycom Community.
This sounds like different Issues.
The dialing via the specific Button and being unable to dial may be a digitmap issue, please check => here <= if this matches.
This would only affect you if you are dialing a number when listening to the dial tone as the Phone's pre defined north American dial plan would check the numbers you are adding.
As you have not really provided enough Information I can only guess that this is called by this.
For your second issue with being unable to hear the conversation I would recommend you check this via a wireshark trace as explained => here <=
Other community members are welcome to comment but for further support please contact your Polycom Reseller.
Best Regards
Steffen Baier
