Hi Guys, I have a strange problem. The handset is a Yealink T46G unit. Provisioned using 3CX Auto Provisioning. Under the Extension status tab, the unit is ALWAYS calling *60 (See attached image) If I call the extension from another line it Rings on the handset but when i pick it up there is no audio either. Every other extension seems to be working fine, its just this one phone. I updated it to the latest firmware 22.214.171.124 and still the same problem occurs. Whats weird is that it was working ok then i enabled Secure SIP (TLS) and SRTP uploaded the certificate into all the phones and this is the only one that stopped working. Its also showing up in the log that the phone is actually on a call 11-May-2015 13:30:07.109 Currently active calls - 1:  But nothing is displayed on the screen except the normal idle status screen. So confused.
