[Kamailio-Users] Openser-Asterisk Codec conversion..
by Rawshan Iajdani 24 Jan '09

24 Jan '09

My scenario is like that.. UA----->OpenSer(Outbound Proxy)---------Register Server | | | | Asterisk(codec converion)---------------------- The UA will register to Register server through outbound proxy OpenSer. When UA makes call it first comes to Openser, OpenSer should route the media to Register server through Asterisk for codec conversion. OpenSer will not hold any User account rather it will act as a proxy. The way I am thinking.. Openser could be used as outbound proxy that's fine. If it were used as outbound proxy, can it also route the media? In the asterisk side I may need username/password pair of UA to dial to Register Server in the second leg. Can I read the User/Pasword from Openser after UA is registered to OpenSer. I can have both OpenSer and Asterisk to reside on the same machine with different IPs so they can access the database if required..

[Kamailio-Users] CarrierRoute With + Prefix
by Ali Jawad 23 Jan '09

23 Jan '09

Hi All I was able to setup carrierroute in database mode and when I make a call with prefix 00 it works fine. For that I did setup an entry in carrierroute, I did duplicate that same entry for prefix "+". If I call 004353453 it works fine however if I dial +12341234 I get a 403 forbidden error. The log shows: Jan 23 14:22:34 [25866] DBG:carrierroute:get_route_tree_by_id: tree default, domain 0 : 0 Jan 23 14:22:34 [25866] INFO:carrierroute:rewrite_uri_recursor: URI or route tree nodes empty, empty flag list Jan 23 14:22:34 [25866] INFO:carrierroute:cr_do_route: rewrite_uri_recursor doesn't complete, uri +9613041705, carrier 5, domain 0 Any guidance please ? With Regards

[Kamailio-Users] [presence] use case of a user that doesn't un-REGISTER and un-PUBLISH
by Pascal Maugeri 23 Jan '09

23 Jan '09

Hi Using kamailio v1.5 (trunk), I'm testing the following simple presence scenario where one user shutdowns his application without prior un-PUBLISH and un-REGISTER. 1) user A subscribes to user B presence. Both use X-Lite. 2) user B shutdowns his X-Lite (without doing un-REGISTER and un-PUBLISH of his presence information), 3) user B starts again X-Lite, registers and publishes his presence, from that point when user B updates his presence information, user A does not see the updates ! I've configured kamailio to use save("location", "0x04") instead of save("location") for incoming REGISTER but this does not help. Is there a way to clean presence DB tables properly when user B register again ? Regards, Pascal

[Kamailio-Users] Carrieroute help
by Ali Jawad 23 Jan '09

23 Jan '09

Hi All I was finally able to setup carrierroute on Solaris :). I am using carrierroute in db mode and I did setup two entries with rewritehost in carrierroute and two entries in route_tree with one route being default. I am still very new to carrierroute as a sample start I do have two astersisk servers that will act as pstn_gw and I want to split the traffic in half between both servers. Can anyone please provide sample instructions on what to put into the route{} statement in this scenario and any main ideas about route_tree and carrierroute ? Thanks.

[Kamailio-Users] Carrierroute and AVP
by rod 22 Jan '09

22 Jan '09

Hi, I'd like to know if there is a way to retrieve the information from the carrierroute module in AVPs. Example: - a prefix has matched, and I'd like to get the field "description" associated with this route and add it in the SIP header - a prefix has matched, and I'd like to get the field "rewrite_host" associated with this route and use it with xlog Thanks, rod.

[Kamailio-Users] htable dictionary attack example
by jh＠tutpro.com 22 Jan '09

22 Jan '09

htable module README has a dictionary attack limitation example. i'm afraid to "try it at home", because it seems to me that it in turn opens up a dos attack possibility: exhausting proxy shared memory by generating requests with random $au values. in order to avoid that, the script should include check if $au exists before adding it to dictionary. on am i missing something? -- juha

[Kamailio-Users] BYE to the wrong IP
by Danny Fröberg 22 Jan '09

22 Jan '09

I need some hints as to what can be going on; Running: openser-1.2.2-tls Mobile 1 à PSTN à Provider SER à Local SER à Asterisk (Callforward) à Provider SER à PSTN à Mobile 2 When Mobile 2 hangs up, Mobile 1 does not get disconnected but hangs with dead air. Provider SER: Is load balanced using standards DNS round robin with one CNAME pointing to two IP's Our BYE goes to the wrong IP even though we use; modparam( "rr", "enable_full_lr", 1 ) ... fix_nated_contact(); force_rport(); if ( ! search( "^Content-Length:\ 0" ) ) { fix_nated_sdp( "3" ); }; t_on_reply( "1" ); record_route(); if ( loose_route() ) { route( 1 ); break; }; I have tested with check_via = yes to no avail. Do any of you have any idea what might be causing this? I know the provided information is sparse but thought I'd try the short descriptions of the problem first, if it's a known miss config. Many Regards Danny Froberg
