I am trying to setup FreeSWITCH with TLS,
It is the Sofia status :
internal profile sip:[email protected]:5060 RUNNING (0)
internal profile sip:[email protected]:5061 RUNNING (0) (TLS)
the port for TLS is ok and up.
I can connect with TLS with FSClient.
When I use a SIP phone , 3CX or EyeBeam I cannot connect to this server.
I have installed cafile.pem in both windows client and SoftPhone as a trusted root certificate but there is a problem in the NEGOTIATING procedure :
tport.c:2754 tport_wakeup_pri() tport_wakeup_pri(0xb6c0ce38): events IN

I used with WireShark to sniff packets and what I found is that 'Hello Client' request by FSClient has different size and extensions compare to the one sent by 3CX. 3CX does not specify any extensions which is obviously is not mandatory.
FSClient Sends this request packet :
