hi does anyone have a source of documentation that can help me setting up the following? one SER box (with a potential additional box for failover) should - Accept REGISTER and so on and just balance these over n asterisk boxes in behind. No authentication should be done on the SER box. - Accept INVITE and distribute this linearly to n asterisk boxes behind, starting with box 1, allow up to n calls to each box (each box having n PRI/E1s). - Accept INVITE from the asterisk boxes and forward these to the client - All RTP traffic should be proxied locally All help appreciated :) roy
