I have existing FreePBX and I need install and configure TFTP or SFTP for SIP URI for Polycom phones. VXX410 and 411 - looks like SIP URI is not configurable from GUI that's why I need TFTP with specific configuration for phones. This is included in Polycom UC admin manual
UC release. So building the config for the phone including SIP URI. Also explaining how that works, as well as answer to any questions after project is done - its a must of this project as a part of requirement.
