Summary:                    Can't provide secure audio requested in SDP offer
Description: 
Hello,

I am running * version 1.8.3.2 on opensuse 11.3 x86_64

we have a lot of Voice over WLan phones attached to our * , which use * as
a generic gateway to our Nortel CS1KE (rel 5.5).

I wanted to upgrade from * 1.6.0.24 to latest 1.8.X version.

when now calling from SIP phone to Nortel everything is okey, all calls
work no problem.

but when I want to transfer an existing wlan-nortel call to a 2nd nortel
phone I get an error in the asterisk console.
also the RTP stream is dead on both ends, and noone can hear the other.

Asterisk is not offering crypto!  It is the Nortel that is offering
crypto.

Before Asterisk was probably ignoring crypto parameters in incoming
requests, but now it knows when it can't handle them, so is actively
refusing them.
