Thanks Jason,

I do TLS/SRTP with some other Phones (Snom/X-Lite/Other_Freeswitches).
This works nad I have those crypto lines.
But I couldn't get it work with my E71 and I am struggling whether I
should invest more time into it. I am sure it's on the Symbian side.

This was just to ask if anybody manged to get it to work. I you all tell
me: "Peter I tried, it doesn't work, please do not invest any time", or
"it works", this would be very helpful information for me.

Best regards
Peter
