Assuming that the same address can be sent to all user agents that communicate with that Asterisk instance, the media_address setting could potentially be used to specify an IPv6 address to send media to, while keeping the signalling on IPv4. -- 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?
