Hello Randeep,
welcome to the Polycom community.
I would usually refer you to your reseller as without Wireshark Trace , Log Files and Configuration Files it is hard to verify your setup.
The SIP release 3.2.3 introduced a change for the Payload Type from 101 to 127.
The Standard tone.dtmf.rfc2833Payload="127" could be not compatible with your SIP Server and may needs to be changed.
This cannot be done via the GUI or the Web Interface.
If you are not already familiar with the Polycom Provisioning please make sure your read => this <= guide describing how to setup a Freeware FTP Server.
Please contact your Polycom Reseller for any further support.
Best Regards
Steffen Baier
