[Serusers] Own Module
by Kapil Dhawan 04 Mar '04

04 Mar '04

Hi i want to allow other ppl to use my declared function..how can this be done.... what i have done is..i have properly declared a function call like this {"load_tm", (cmd_function)load_tm, NO_SCRIPT, 0, 0}, as in tm module...but how can we include all this stuff in some other module or lets say....vm module declares one function called vm_action which can be called by ser.cfg only...but i will change it to be called from other modules as well...now in my module how can i use that function vm_action...how to define it..etc...i hope i explained my problem.... regards _________________________________________________________________ Skin is in!

[Serusers] Calls cuts off

Hello, I'm facing some very different when making calls with an ATA... it happens exactly as a msg written to the list a couple months ago, but I found no response for this question. It's weird cause it does not happen when I call from an ATA to another ATA with alias on the same proxy. Any clues?! Thanks.. Billy [Serusers] Session Header != Media ?

Re: [Serusers] Strange error when using group module
by Klaus Darilion 03 Mar '04

03 Mar '04

If you want to authorize INVITEs before sending them to the gateway, you should also challenge the INVITEs. And you should use proxy_challenge for INVITEs and www_challenge for REGISTERs. you can try this: if (method=="INVITE") { if (!proxy_authorize("sip.netsquare.co.uk","subscriber")) { proxy_challenge("sip.netsquare.co.uk", "0"); break; }; if (!is_user_in("credentials","int")) { sl_send_reply("403", " no permission for external calls"); break; }; ...here forward to gateway }; btw: please always CC: to the mailing list. regards, klaus Mike Fallows wrote: > There is a proxy_athorize in the register statement as below. > > > > if (method=="REGISTER") { > > # Uncomment this if you want to use digest authentication > if (!proxy_authorize("sip.netsquare.co.uk", > "subscriber" > )) > { > proxy_challenge("sip.netsquare.co.uk", "0"); > break; > }; > > save("location"); > break; > }; > > -----Original Message----- > From: Klaus Darilion [mailto:klaus.mailinglists@pernau.at] > Sent: 03 March 2004 09:34 > To: Mike Fallows > Cc: serusers(a)lists.iptel.org > Subject: Re: [Serusers] Strange error when using group module > > > There are no credetials (username/password) in the incoming request. > Have you requested credentials with proxy_authorize(...) ? > > klaus > > Mike Fallows wrote: > >>Anyone help me with this one. >> >>I am trying to group users so that some are allowed place SIP->SIP calls > > via > >>the proxy, and others are also allowed to access the PSTN. >> >>An extract of the ser.cfg is below: >> >>if (!is_user_in("credentials","int")) { >> sl_send_reply("403", " no permission for external calls"); >> break; >> } >> >>When this is called, I receive this in /var/log/messages: >> >>Mar 2 22:04:41 ns-nby-ser1 /usr/local/sbin/ser[6988]: is_user_in(): No >>authorized credentials found (error in scripts) >> >>And the user fails to connect. >> >>Any ideas would be greatly appreciated. >> >>Mike >> >>_______________________________________________ >>Serusers mailing list >>serusers(a)lists.iptel.org >>http://lists.iptel.org/mailman/listinfo/serusers >> >> > > > >

[Serusers] SER talks SIP to Jabber Server
by Délio Filipe Russo Guerra 03 Mar '04

03 Mar '04

I'm having a problem putting jabber gateway to work. I'm using SER 0.8.12 and microsoft messenger 4.7 as a SIP client and PSI as a Jabber client. I had configured the jabber gateway in ser.cfg and i can talk between the to clients (at least for a while). I'm using user1 as both SIP client and jabber client, and user2 as a jabber client only. So the SIP address for the user1 is sip:user1@sipserver.sipdomain. user1 also have an jabber account user1(a)jabberserver.jabberdomain. user2 as an jabber account user2(a)jabberserver.jabberdomain. I start to talk from user1 (microsoft messenger logged in SIP server) to user2 (PSI logged in jabber server) and it works just fine. If i continue to talk in this direction i have no problems. When i start to talk from user2 (PSI logged in jabber server) to user1 (microsoft messenger logged in SIP server) i have no problems either. The problem appears when i want to talk again from user1 to user2... that is, when i receive the first response from user2 -> user1 it blocks the way user1 -> user2. I've put a sniffer to find out why this appened, and appears that after user2 responds, all the events (Ex: INFO for Keyboard Activity) or messages from user1->user2 are SIP to jabber server. It seams that SER is not using the jabber gateway. Can anyone help me please... Délio Guerra IT - Instituto de Telecomunicações Universidade de Aveiro - Portugal

[Serusers] sip-communicator
by Eduard San Anselmo Mateu 03 Mar '04

03 Mar '04

Hello everyone. I'm testing SER with some different clients, to see which one fits our needs better. The last one we tried was sip-communicator (java softphone), but I'm experiencing some problems with it. At first, everything seems to work well, but after a few seconds, the client says it's unregistered (when that's not true). Another issue is that when SER returns the 200 OK response to the REGISTER request, it has three different Contact headers, with different port numbers. The config file is this one: listen=192.168.0.15 alias=albasoft.com alias=albasoft.com:5060 alias=192.168.0.15 #alias=192.168.20.15 #alias=192.168.20.15:* #alias=192.168.20.15 # ------------------ module loading ---------------------------------- # Uncomment this if you want to use SQL database loadmodule "/usr/lib/ser/modules/mysql.so" loadmodule "/usr/lib/ser/modules/sl.so" loadmodule "/usr/lib/ser/modules/tm.so" loadmodule "/usr/lib/ser/modules/rr.so" loadmodule "/usr/lib/ser/modules/maxfwd.so" loadmodule "/usr/lib/ser/modules/usrloc.so" loadmodule "/usr/lib/ser/modules/registrar.so" loadmodule "/usr/lib/ser/modules/textops.so" loadmodule "/usr/lib/ser/modules/nathelper.so" modparam("usrloc", "db_mode", 2) modparam("rr", "enable_full_lr", 1) route{ # initial sanity checks -- messages with # max_forwards==0, or excessively long requests if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; if (msg:len >= max_len ) { sl_send_reply("513", "Message too big"); break; }; if (loose_route()) { # mark routing logic in request append_hf("P-hint: rr-enforced\r\n"); route(1); break; }; if (!uri==myself) { # mark routing logic in request append_hf("P-hint: outbound\r\n"); route(1); break; }; # if the request is for other domain use UsrLoc # (in case, it does not work, use the following command # with proper names and addresses in it) if (uri==myself) { if (method=="REGISTER") { # Uncomment this if you want to use digest authentication # if (!www_authorize("iptel.org", "subscriber")) { # www_challenge("iptel.org", "0"); # break; # }; force_rport(); save("location"); break; }; lookup("aliases"); if (!uri==myself) { append_hf("P-hint: outbound alias\r\n"); route(1); break; }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); break; }; if (method=="INVITE" && !uri=~"sip:.*@192\.168\.0\..*") { log(1,"IEEE: la peticio va cap a fora\n"); #fix_nated_sdp("1"); #force_rtp_proxy(); #t_on_reply("1"); }; }; append_hf("P-hint: usrloc applied\r\n"); route(1); } route[1] { # send it out now; use stateful forwarding as it works reliably # even for UDP2TCP if (!t_relay()) { sl_reply_error(); }; } onreply_route[1] { if (status =~ "(183)|2[0-9][0-9]") { if (!src_ip=~"192\.168\.0.\.*") { log(1,"onreply_route si que funciona\n"); #force_rtp_proxy(); }; }; } By the way, sip-communicator doesn't seem to be symmetric: the clients works on a random port, and the server, on 5060 (configurable), and those different Contact headres I've explained, are for 5060, and the three ports following the one sip-communicator has made the request from (for example, 1066, 1067, 1068). Thanks in advance. Eduard San Anselmo

[Serusers] Multiple IP Addresses

Hi List, Is there a way to force SER to send requests from a user defined IP address when used on a multihomed system? We have a box with two consecutive addresses 81.x.x.81 81.x.x.82 the primary address is .82 but it always uses .81, doesn't matter which way around the listen statements are.
