Hi All,
As you guys might remember I have been doing alot of work with these legacy 
handsets recently, in particular the Cisco IP phones 7945G and 7965G.
They work well now with kamailio, using UDP or TCP as the transport protocol.
I am now looking to implement SIP over TLS with them, and wondered if anyone 
had completed the same, as it appears they were designed very much to support 
SIP over TLS and SRTP but with Cisco call manager and not other SIP devices.
I am trying to understand if its possible to integrate with kamailio, as from 
Cisco documentation it appears a CTL file (client trust list) is required which 
seems to be generated by cisco software, and the handset needs it before it 
will try to initiate a SIP connection over TLS.
I have implemented TLS /SRTP with Cisco SPA's, Bria etc on kamailio fine, so 
its more a question around the handset and if anyone has achieved this.
Thanks
Jon
