[Users] t_replicate to multiple destinations
by Marco 04 Dec '06

04 Dec '06

Hi all, I read on the docs of the tm module that I can use t_replicate to send, for example, REGISTER to multiple destinations. Can a I replicate to more than one server, such as t_replicate("sip:1.2.3.4") t_replicate("sip:1.2.3.5") t_replicate("sip:1.2.3.6") and so on ? >From the docs it seems possible, but I don't know how to set branches.

[Users] test openser behind NAT not work
by somsak vattanavakin 04 Dec '06

04 Dec '06

Dear All i will setup openser behind NAT like these OPENSER ---> ADSL ROUTER(A) <---> INTERNET <---> ADSL ROUTER(B)<-- UAC(1) <-- UAC(2) for UAC to talk each others in the same network with OPENSER server and try to REGISTER AND INVITE IT OK . but if i use UACs that located behind ADSL ROUTER(B) for REGISTER it OK when UAC(1) INVITE UAC(2) it RING and session established can heard sound but after about 30 second the CALLEE UAC(2) is HANG UP while CALLER UAC(1) still show established i saw some mail said that the problem may occour from ADSL ROUTER ITSELF (AGL problem)or some say that ACK problem. if i connect UAC(1) and UAC(2) through ADSL ROUTER(B) to iptel.org and i use UAC(1) INVITE UAC(2) it work no problem for 30 second disconnection . also if i use UAC(1) and UAC(2) conect to iptel.org through ADSL ROUTER(A) no problem . AT this point can I CONCLUDE THAT BOTH ADSL ROUTER NO PROBLEM FOR SIP CONNECTION. is it TRUE ?? Next i saw from LOG file it seem no ACK MESSAGE and error like these -- LOG FILE ------------- ERROR: tcp_blocking_connect: poll error: flags 18 ERROR: tcp_blocking_connect: SO_ERROR (111) Connection refused ERROR: tcpconn_connect: tcp_blocking_connect failed ERROR: tcp_send: connect failed --- for simply NAT testing i use openser.cfg like these ---------- OPENSER.CFG --------- if (!method=="REGISTER") record_route(); if (loose_route()) { # mark routing logic in request append_hf("P-hint: rr-enforced\r\n"); route(1); }; if (!uri==myself) { # mark routing logic in request append_hf("P-hint: outbound\r\n"); route(1); }; if (uri==myself) { if (method=="REGISTER") { if (!www_authorize("infowavenet.com", "subscriber")) { www_challenge("infowavenet.com", "0"); exit; }; fix_nated_register(); save("location"); exec_msg("cat >> /tmp/test"); exit; }; lookup("aliases"); if (!uri==myself) { append_hf("P-hint: outbound alias\r\n"); route(1); }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); exit; }; 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 fix_nated_contact(); if(method == "INVITE") { fix_nated_sdp("3"); } if (!t_relay()) { sl_reply_error(); } else { exec_msg("cat >> /tmp/test");} exit; } ------------ MY QUESTION: 1) can openser server is BEHIND NAT ADSL ROUTER and receive Call from UAC from other NAT ROUTER . 2) if so what the problem that CALLEE HANGUP every 30 seconds ( i use XLITE v.3 for UAC ) 3) if it possible can you fix openser.cfg that work for this situation Best Somsak Vattanavakin

[Users] two invites, different session description => broken
by John Peters 02 Dec '06

02 Dec '06

Not sure why that's happening. Probably setting canreinvite=no on the asterisk side will eliminate the re-INVITEs as a temporary solution, but still would like to know what is happening... wrote: > Sometimes, a calls b and b hears a, and a hears b for a second but a second > INVITE comes to phone B that causes it to redirect rtp to be point to point. > Sometimes there is no audio. > Sometimes, everything works fine. > At one point, rtp from a was going to asterisk, but asterisk was not sending > the rtp on to b, and b was trying to send traffic point to point.

[Serusers] forward_reply error
by johnk＠koreanet.us 02 Dec '06

02 Dec '06

Hi all. After UA makes a PSTN call, if remote PSTN peer hangs up first, server correctly receives BYE from gateway, hit BYE section in config and CDR records accordingly through radius. But if UA hangs up first, BYE section in config never gets hit, instead server logs "ERROR: forward_reply: no 2nd via found in reply" right after " ACC: transaction answered:...", which was logged when the call was answered by called PSTN. CDR accounting only records without STOP time and duration being zero. Any comments will be appreciated.

[Serusers] onreply_route and EXEC module
by Benito Caracuel 02 Dec '06

02 Dec '06

Hello all, I need to execute an exec_msg command inside onreply_route code buy SER doesn't permit this. This is my ser.cfg: route{ ...... if (method=="INVITE"){ .......... t_relay(); route(2); break; }; route[2] { t_on_reply("2"); } onreply_route[2] { if (status=~"200"){ if ( search("msrp:") ){ exec_msg("printenv SRCIP > /tmp/200ok.txt; cat >> /tmp/200ok.txt; /bin/bash /usr/local/ser_snapshot/sbin/controlador2"); replace_all_file("msrp:\/\/[0-9\.:\/;a-z]*\r","/tmp/pathmsrp200ok.txt"); } } } In onreply_route, I need to execute exec_msg to manipulate 200 ok, but SER doesn't permit it. What can I execute exec_msg?? I try to probe this: route[2] { t_on_reply("2"); } onreply_route[2] { if (status=~"200"){ if ( search("msrp:") ){ t_on_failure("2"); } } } failure_route[2] { exec_msg("printenv SRCIP > /tmp/200ok.txt; cat >> /tmp/200ok.txt; /bin/bash /usr/local/ser_snapshot/sbin/controlador2"); replace_all_file("msrp:\/\/[0-9\.:\/;a-z]*\r","/tmp/pathmsrp200ok.txt"); t_relay(); } But never enter in failure route!!!

[Serusers] Use TCP protocol
by Katty Xiong 01 Dec '06

01 Dec '06

Hi, I am trying to do some tests using TCP protocol with SER as a proxy. SER accepts SIP message through TCP correctly, but after SER accepts SIP messages, SER automatically picks up UDP for transmission. Is there a way to force SER to use TCP for forwarding message? thanks, Joy ____________________________________________________________________________________ Want to start your own business?

[Serusers] Problem with ser-freeradius-mysql
by Lokesh Kumar 01 Dec '06

01 Dec '06

Hello list, I had ser-0.9.6, freeradius-1.1.3 and mysql installed. I am doing AAA for ser by freeradius where freeradius should have to fetch data from default mysql tables setup by freeradius. I am able to do authentication of sip clients without problem, accounting packets also gets logged into mysql database (when group membership checking disabled in ser.cfg).But I am unable to manage with group membership check. I am not sure what should be the AVPs I have to insert into mysql tables for group membership check. I followed various articles about freeradius and ser, and tried all possibilities, but no success. Can anyone give me any clue about that. Below mentioned are some of my conf files. In radiusd.conf I had enabled “sql” and disabled “files” in order to read values from mysql db instead of flat files. Part of ser.cfg for radius group check if (!lookup("location")) { if(uri=~"^sip:0[1-9].*@abc.xyz.pt") { #Towards National PSTN gateway if (!radius_is_user_in("From", "ld")) { sl_send_reply("403", "No permission to call on National numbers..."); break; }; route(4); route(5); break; }; In radcheck table I have 2 entries for each user they are like mentioned below mysql> select * from radcheck; +----+--------------------------------+---------------+----+-------------+ | id | UserName | Attribute | op | Value | +----+--------------------------------+---------------+----+-------------+ | 1 | 69021(a)abc.xyz.pt | User-Password | == | "teste" | 17 | 69021(a)abc.xyz.pt | Auth-Type | := | Digest usergroup table has entry like below mysql> select * from usergroup; +----------------------------+-----------+----------+ | UserName | GroupName | priority | +----------------------------+-----------+----------+ | 69021(a)abc.xyz.pt | ld | 1 | +----------------------------+-----------+----------+ 1 row in set (0.00 sec) And radgroupcheck has entries like mentioned below mysql> select * from radgroupcheck; +----+-----------+--------------+----+-------------+ | id | GroupName | Attribute | op | Value | +----+-----------+--------------+----+-------------+ | 1 | ld | Service-type | == | Group-Check | +----+-----------+--------------+----+-------------+ 1 row in set (0.00 sec) Any clue will be much appreciated..

[Users] SIP over TCP or TLS - Contact Header - NAT problematic
by Christophe Irles 01 Dec '06

01 Dec '06

Hi, If a SIP device is using TCP, to accept incoming calls it must bind on port 5060. To call someone, this device must create a socket to reach the proxy on port 5060. The port source of this socket cannot be 5060 ! In TCP you cannot bind on a port and in same time using it in another socket. So the port source is generally chosen randomly (XYZ) Now that all sockets and bind are done, what are the correct info used to create the Contact header ? For me, the port used in the contact header in this case must be 5060 since the device accepts incoming calls on this port and never XYZ. But in a NAT context, if this SIP device is behind a NAT, the port 5060 cannot be used to reach it ! It's necessary to reuse the socket previously opensed to reach it. So in conclusion, the Contact header must be set with 5060 by the device and on the proxy side, if the client is detected behind a NAT, this Contact header is modified to used instead XYZ Am I right ? For TLS, the problem is the same but instead of 5060 it's 5061. Thanks, Christophe
