Is that necessary for some legacy systems? I'm not sure why it would be a configuration option. The 'must' I referred to comes from Section 6 of RFC 4568. Its certainly possible that there is some PBX out there that did not understand a SRTP transport designation. > Also I am wondering if it's possible to tell asterisk to just ignore > the crypto line when the profile is just RTP/AVP / not to take > things that serious?

Asterisk does not currently have a setting for that - if it encounters a security descriptor in an SDP offer, it will attempt to process it. -- Matthew Jordan Digium, Inc. | Software Developer 445 Jan Davis Drive NW - Huntsville, AL 35806 - USA Check us out at: http://digium.com & http://asterisk.org -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
