[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

[Users] Problem Radius Authentication - NO username in DIGEST-URI
by bogos dan-cristian 01 Dec '06

01 Dec '06

Hello Folks, I got some strange issue with RadAuth module. I have a running server which works just great with RadAuth. The problem comes when in the FROM and TO headers are no descriptions. EG: Following request will be properly processed: # INVITE sip:0012345@babble.net SIP/2.0. To: "0012345"<sip:0012345@babble.net>. From: "Some User"<sip:user@babble.net>;tag=5a7e9242. BUT the following one will not: INVITE sip:00123456@babble.net SIP/2.0. To: <sip:0012345@babble.net>. From: <sip:user@babble.net:10101>;tag=1-2963920204. Here is what I will get WRONG in RADIUS Server: Packet-Type = Access-Request Thu Nov 30 22:52:31 2006 User-Name = "user(a)babble.net" Digest-Attributes = "\n\020user(a)babble.net" Digest-Attributes = "\001\014babble.net" Digest-Attributes = "\002*456f61dc0d715ea80fd0ed0431df75b73a4c4092" Digest-Attributes = "\004\020sip:babble.net" Digest-Attributes = "\003\010INVITE" Digest-Response = "c96792da6dfb093215150ccd250fac34" Service-Type = Sip-Session Sip-Uri-User = "user" NAS-IP-Address = 127.0.0.1 NAS-Port = 5060 Client-IP-Address = 87.102.50.17 The problem is that in the Digest-URI part I will not get the sip:0012345@babble.net, but the sip:babble.net, therefore completly erroneous info. I have checked with xlog the request on openser server just before passing the info to radius_proxy_authorize function, and all the FROM-URI, TO-URI, R-URI avps were just fine. Can somebody from the DEVELOPERS help me? I cannot see other solution, since there is nothing to be tuned in the settings of radauth module. Thank you in advance for your time!

[Serusers] Download for later version of SER - "cvs head"?
by Paul Antinori (pantinor) 01 Dec '06

01 Dec '06

I have been using 0.9.6 version of SER that has DNS SRV load balancing, but now want to try the build that has DNS SRV failover/rollover capabilities built in using the SRV priority. I think this is called the "CVS HEAD" build. I cannot see this on the FTP download directories. Is this available? Thank you, Paul

[Users] Questions about regexp and AVPs
by Mahesh Paolini-Subramanya 30 Nov '06

30 Nov '06

I think I'm missing something pretty obvious here, but is there a reason that avp_check("$avp(tmpVar1)", "re/$avp(myNetwork0)/i") barfs on 1.1.x? I get the error 0(0) ERROR:avpops:fixup_check_avp: regexp operation requires string value 0(0) ERROR: fix_actions: fixing failed (code=-1) at cfg line 3491 In the above, $avp(tmpVar1) == "1.2.3.4" $avp(myNetwork0) == "1.2.3" Now, I'd hoped that I could actually run the following avp_check("$avp(tmpVar1)", "re/^$avp(myNetwork0)/i") but that doesn't work Then, setting $avp(myNetwork0) == "^1.2.3" and running avp_check("$avp(tmpVar1)", "re/$avp(myNetwork0)/i") didn't work either Sooo, whats the solution? avp_check can't have AVPs on both sides of the check? cheers -- ******************************************* Mahesh Paolini-Subramanya (703) 386-1500 x9100 CTO mahesh(a)aptela.com Aptela, Inc. http://www.aptela.com "Aptela: How Business Answers The Call" *******************************************
