Re: [OpenSER-Users] OpenSER as a conditional stateless proxy

by lu

Hi, Iam too interested in this discussion, can some one explicitly elaborate how iam gonna satisfy all the conditions in a situation whereby OpenSER is relaying to Asterisk for local PSTN calls and to another a voip provider for International PSTN calls, ofcourse this applies for any numeric uri. I have a Sipwise generated config with offnet-termination which i tried to edit route [5] 'invite-find-calee' using t_relay() and rewritehostport conditions, but my concern is the role of LCR module which is supposed to be taking care of the GWs especially in route[7] "Request route invite-to-external", will it gonna disrupt/conflict my set conditions?? ######################################################################## # Request route 'invite-find-callee' ######################################################################## route[5] { if(alias_db_lookup("dbaliases")) { xlog("L_INFO", "Callee was aliased - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); #CHECK WHERE THE REQUEST IS FROM???-edit by me if($fd=="sip.domain") { #FORWARD THEM TO ASTERISK -edit by me rewritehostport("asterisk IP"); #AND THEN TAKE THEM TO REQUEST ROUTE 'base-outbound'-edit by me route(3); } else if(uri=~"Sip:00[0-9]+@"){ #RELAY THEM TO INTERNETIONAL PSTN-edit by me t_relay("IP_of_international_PSTN_ provider"); route (3); } if(!is_domain_local("$rd")) { setflag(20); route(7); } if(does_uri_exist()) { xlog("L_INFO", "Callee is local - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); route(6); } else { xlog("L_INFO", "Callee is not local - M=$rm RURI=$ru F=$fu T=$tu IP= $si ID=$ci\n"); route(7); } exit; } ######################################################################## # Request route 'invite-to-external' ######################################################################## route[7] { if(isflagset(20)) { xlog("L_INFO", "Call to foreign domain - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); route(3); exit; } if(!isflagset(23)) { # don't allow calls relaying from PSTN to PSTN, if not explicitely forwarded if(uri =~ "^sip:[0-9]+@") { # only route numeric users to PSTN if(!load_gws()) { xlog("L_ERR", "Error loading PSTN gateways - M=$rm RURI=$ru F=$fu T= $tu IP=$si ID=$ci\n"); sl_send_reply("503", "PSTN Termination Currently Unavailable"); exit; } if(!next_gw()) { xlog("L_ERR", "No PSTN gateways available - M=$rm RURI=$ru F=$fu T= $tu IP=$si ID=$ci\n"); sl_send_reply("503", "PSTN Termination Currently Unavailable"); exit; } setflag(21); t_on_failure("1"); route(3); } } xlog("L_INFO", "Call to unknown user - M=$rm RURI=$ru F=$fu T=$tu IP= $si ID=$ci\n"); sl_send_reply("404", "User Not Found"); exit; } WBR, LU.

[OpenSER-Users] SIP Topology Question

by Brandon Armstead

Hey Guys, just looking for some input on this, thanks! Basic Topology ------------------------------- Core Route Servers - Server A, B Registration Server, Collects USRLOC which all reports to the SAME DATABASE. Server C (User A initial registration server) User A -> it will tell me location Server D User A -> it will tell me location Any complications, I should be aware of? So Call Flow will look like so: INBOUND CALL: (Server A|Server B) -> (Server C|Server D) -> (END USER) Now should I be weary of any "lockings" such as a client end such as cable/dsl modem, the ata itself, etc? Thanks. -- Brandon Armstead

[OpenSER-Users] Redundant mysql

by Antonio Reale

Hi all, I'm trying to setup Openser with two Mysql server configured as Master-Master. Is it possible to configure Openser to read data from the first Mysql server (192.168.1.4) and if that fails to read data from the second Mysql server (192.168.1.5)? If not, which alternatives I have to instruct Openser to use the second Mysql server when the first is down? Thanks in advance. -- Antonio

[OpenSER-Users] [IMC module] What are imc tables for?

by Iñaki Baz Castillo

Hi, in order to use chat rooms I'd like to manage them just from a web interface that handles imc_rooms and imc_members table, but sincerely I don't know how to use them, I don't see doc about hot to use the tables. What I'd like is to have "fixed" chat rooms without the need of creating them with commands, but via web. Could anyone explain me how to use those tables? Please, explain me with this example: - I want a chat room for domain "domain1.org" and name "chat1". - I want three members for that room: - user1(a)domain1.org - user2(a)domain1.org - other_user(a)other_domain.org Could you fill the tables please? ** imc_rooms table ** name domain flag ** imc_members table ** username domain room flag What is flag for? I suppose it's for features as private/public tables and so. Maybe it's not possible to manage those tables and the only way is using chat commands? Thanks for any help and best regards. -- Iñaki Baz Castillo

[OpenSER-Users] [group module] Realtime in 're_grp' table?

by Iñaki Baz Castillo

Hi, I need the possibility of users in many groups. This is not allowed by "grp" table where username, domain and grp are UNIQUE key. So It could be valid for me using "re_grp" table and managing numeric groups. But "re_grp" table doesn't allow realtime (if I do a INSERT or UPDATE in the table I need to restat OpenSer). Is not possible to use "re_grp" table in realtime mode? Thanks. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

Re: [OpenSER-Users] mi_xmlrpc.so: undefined symbol: ConfReadServerFile

by Bogdan-Andrei Iancu

Hi Gregorio, Probably you need to link the module against some other lib provided by xmlrpc-c package. Try to use the latest 1.2.x (stable) or 1.3.x (testing) as they have some auto lib detection. Otherwise, you need to change in modules/mi_xmlrpc/Makefile the list of libraries to be used for linking the module. regards, bogdan Gregorio wrote: > > Hi all. > > I have a problem starting ‘mi_xmlrpc’ module.

[OpenSER-Users] maddr in contact

by Allan Chao ( 趙廷睿 )

Hi : I have a flow UE -> gateway (use openser and runs proxy mode) ( ip : 192.168.1.2) -> SIP Proxy ( ip: 192.168.1.3), if i have two user , UE1(192.168.1.5) and UE2(192.168.1.6) send REGISTER request to SIP proxy through gateway, but our gateway add a maddr = "192.168.1.2" string in contact header,so the contact in REGISTER becomes <username@ host ; maddr="192.168.1.2">. now , if UE1 send INVITE message to UE2, how does sip proxy to do if receive INVITE message? it will send invite message to UE2 through gateway ( maddr parameter) ? and does openser has support maddr in contact or not . thx. allan
