Re: [Serusers] Anonymization/uac-module questions

Hi all, First of all two common anonymization questions: Is it save for anonymization to alter the Contact-Header in SER if record_route() is used to strip the username/IP? If not, how do you accomplish this correctly? And is there a way to modify the SDP body to change the o-Field to change/remove the IP of the owner/creator? Then an uac issue: The uac module (backported to ser-0.9 with "MANUAL RESTORE" mode) works well for me in this scenario: The group "clir" indicates anonymization, and the config looks like this: modparam("uac", "from_restore_mode", 2) route { # ... if(is_user_in("From", "clir")) { setflag(7); uac_replace_from("Anonymous", "sip:anonymous@my.domain"); } t_on_reply("1"); t_relay(); } onreply_route[1] { if(isflagset(7)) uac_restore_from(); } When A calls B and A is in group "clir", the From-Header sent to B is anonymized, and responses to A are restored correctly. But when B hangs up, the UAC of B (Cisco-ATA186 or Mediatrix 2102) changes From and To in the BYE message, so A receives the anonymized From-Header as To-Header. This is because uac_restore_from() only restores the From-Header (as the name of the function says ;o) ), not the To-Header if there is a vsf-Parameter available. This isn't correct behaviour, is it? Also the Cisco-ATA strips off the vsf-Parameter in the BYE-Message so it isn't available anyhow, but this seems to be a Cisco-Bug!? Any Comments/Ideas?
