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.
