[OpenSER-Users] Why every body return "404 Not Found" instead of "480 Not Available"?
by Iñaki Baz Castillo 05 Mar '08

05 Mar '08

Hi, after a large discussion in sip-implementros maillist I realize that a proxy/location server shouldn't reply "404" if a callee DOES exist but it's not registered in that moment. In fact: 480 Temporarily Unavailable [...] This status is also returned by a redirect or proxy server that recognizes the user identified by the Request-URI, but does not currently have a valid forwarding location for that user. 404 Not Found The server has definitive information that the user does not exist at the domain specified in the Request-URI. [...] Why then every body suggest to reply "404 Not Found" when "lookup(location)" returns -1? For example, the "registrar" module doc suggests it: Example 1-22. lookup usage lookup("location"); switch ($?) { case -1: case -3: sl_send_reply("404", "Not Found"); exit; case -2: sl_send_reply("405", "Not Found"); exit; }; Best regards. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

[Serusers] Installing serweb
by Adeyeye O. Michael 05 Mar '08

05 Mar '08

Hi, With the recent development in PEAR Network, where XML_RPC isn't available any longer, has anyone been able to install serweb recently? I can't get XML_RPC package which is one of the requirements to get SERWEB running. Where I was able to get the raw files from PEAR but not ABLE to run "pear install XML_RPC", i can't make install and the likes. Hence, i doubt if XML_RPC will be successfully installed into my PEAR. Any help!! Mike.

[OpenSER-Users] Is possible to convert 183 in 180 in "on_reply_route"?
by Iñaki Baz Castillo 04 Mar '08

04 Mar '08

Hi, in order to avoid replying with early_media I'm trying to transform a "183" with SDP into a "180". Ok, my conclusion is that I cannot do it. Textops functions seem to work just with SIP headers and body but never can modify the SIP reply code, is true? Also, I would need to delete the entire body in the 180|183 reply but functions supposed to do it don't work as expected. For example: * subst_body('/^.*//g') does NOTHING, the only way it can do somehting is by: subst_body('/^.*=.*//g') any reason for this? Thanks for any suggestion. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

[Serusers] How to enable RTCP reports
by Srinivas Kotamarti 04 Mar '08

04 Mar '08

Hi, I am working on a project that uses SER, SEMS and Media Proxy. I was wondering how and where to enable the RTCP reports. I could not find any useful information either in the product documentation or in the user groups. Does any of these products support generating RTCP reports? IF not how do we add the feature and where would be best place to add it? Thanks for the help. --Srinivas Kotamarti

[OpenSER-Users] OpenSER and Security - how?!
by Max Bowsher 04 Mar '08

04 Mar '08

I've been looking at the possibility of using OpenSER as an ingress/egress gateway, mediating access between the internet at large, and a private network containing amongst other things SIP servers through which a call may be routed to provide services such as IVR and call archiving, but which should otherwise be hidden from the outside world. I'm finding two interlinked problems: (1) The internal layout of the network is revealed in Via headers - OK, so this is somewhat intrinsic in SIP, and not really OpenSER's fault, but.... (2) ... If an inbound SIP request has Route headers, loose_route() pretty much sends it whereever the requester asks. There are admonitions in the OpenSER docs about the need to secure loose_route(), but there's no information I can find on how you should do this. In particular, a simple authorization scheme is not good enough - just because someone should be allowed to place calls through the gateway, doesn't mean it should be allowed absolute control over the routing of the request, or they could use information gleaned from Via headers of previous transactions to add or bypass routing steps within the private network at will. It is possible to securely use OpenSER on a security boundary? If so, how? Max.

Hi people... With the Textops Module is possible search for the first match of re in the body of the message and appends txt after it, ex: search_append, search_append_body...
