Hi, Andreas Granig wrote: If you want to use something external (e.g. LDAP directory lookup) instead of using aliases, substitute lookup("aliases"); with exec_dset("/your/external/script"); You will need to write "/your/external/script" to suit your needs. Nimal R.

Hi Andreas, Thank you very much for replay! I have already tried something like that but it doesn't work. I already have failure route and it works fine for numerical destinations, that is, if user isn't in usrloc call is redirected to GW (if I call him by alias). But when I try to replace original sip address with one in aliases [lookup("aliases"); -> rewritehostport] SER doesn't do it. Instead of "rewritehostport" I should have something that will rewrite username with alias not just host and port. I'm not even sure if this is possible, can SER work this way? davor -----Original Message----- From: Andreas Granig [mailto:andreas.granig@inode.info] Sent: Monday, August 08, 2005 8:32 PM To: davor jovanovic Cc: serusers(a)lists.iptel.org Subject: Re: [Serusers] forking with SER davor jovanovic wrote: Maybe something like that? route{ ... t_on_failure("1"); t_relay(); } failure_route[1]{ if(t_check_status("404")){ lookup("aliases"); rewritehostport("your.gateway", "5060"); t_relay(); } } HTH, Andy -----Original Message----- Hi all, I have a question about routing a call to GW when user isn't in location table. If I have a user with SIP address: sip:mister@no.com, and his alias in form of his business phone on office PBX: alias = 1234 can SER use number in aliases and rewrite sip:mister@no.com to 1234(a)no.com? sip:mister@no.com -> "404 Not Found" -> use aliases -> sip:1234@no.com -> t_relay -> GW -> PBX or something like that. So if someone could explain me how can I do this. Do I need some external application to do that and return PSTN number to SER? Or how can I do forking with SER? thanks
