[Serusers] Call Forwarding (No-Answer, Busy)
by reticent 29 Mar '05

29 Mar '05

I've been attempting to implement some call forwarding (noans, busy) logic into my SER script without any luck So far i've tried CPL (which doesn't seem to work at all for call forward busy and apparently doesn't work properly with no answer) (I must say, CPL seems like an excellent feature. Its really a shame that many of its useful functions aren't yet supported in SER) I've also tried setting the "fr_timer_avp" TM parameter from an AVP database and trying to forward the call once the timer expires, so far this has proven fruitless. I'm curious if anyone has found a solution to this problem, or if it possible.

[Serusers] Anonymization/uac-module questions
by Andreas Granig 29 Mar '05

29 Mar '05

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? Andy

Hi All, For the 0_9_0 branch, what is the 'best practice' for implementing parallel forking? We used to be able to point one alias at several accounts, but that feature has regressed. Thanks, -Jev

[Serusers] Forwarding to a LCS server
by Mimmus 29 Mar '05

Hi, I'm setting up SER to act as a proxy between Asterisk and Microsoft LCS (to enable TCP2UDP translation needed to speak with Microsoft LCS). I'd like to keep configuration the simplest as possible. Unfortunately, LCS refuses INVITE with a: <504: Server Timeout> as you can see in following output from 'ngrep' (some security sanityzing performed): ####### T xxx.yyy.64.118:32834 -> 10.99.1.9:5060 [AP] INVITE sip:myuser@mydomain.it SIP/2.0.
