[Serusers] Inaccurate Radius Accounting
by lenirsantiago＠yahoo.com 16 Nov '05

16 Nov '05

Hey guys, I'm using Radius to do pretty much everything regarding my users, i.e. registrations, authorization, features and preferences. I implemented my own way of doing speeddial by using AVPs provided by radius and AVPOPs module, Here is the snippet: AVP-SIP = speedial:30:15615551212 avp_subst("s:caller_speedial/i:99", "/(.*):(.*)/\2/"); #15615551212 avp_printf("i:98","$rU:*"); #30 avp_printf("i:97","sip:$avp($temp2)@$td"); # sip:15615551212@xx.xx.xx.xx avp_printf("i:96","<sip:$avp($temp2)@$td>\r\n"); # <sip:15615551212@xx.xx.xx.xx>. xlog("L_N"," SPEEDIALING: $fU is speed-dialing $hdr(To)->$avp($temp2)\n"); if (avp_check("s:caller_speedial", "fm/$temp1/g")) { #avp_pushto("$To","i:96"); #avp_pushto("$ruri","i:97"); #avp_pushto("$duri","i:97"); #subst('/^To: (.*)(a)(.*)/To: "$avp($temp2)" <$avp($temp2)@\2/'); #append_hf("To: \"5615551212\" <15615551212(a)xx.xx.xx.xx>;user=phone"); #subst_uri('/^sip:(.*)@(.*)$/sip:$avp($temp2)@\2/i'); #subst_user('/(.*)/$avp($temp2)/'); #remove_hf("To"); rewriteuser("15615551212"); xlog("L_N"," SPEEDIALING: $fU is dialing $hdr(To) $avp($temp2)\n"); avp_delete("$temp1/g"); avp_delete("$temp2/g"); }; In this scenario, im forcing it instead of getting the value from AVPs just for ease of showing my point. The problem that I'm having is that no matter what I do to change the To header or change the R-URI, radius ALWAYS sends the accounting records with the original R-URI, in my case 30(a)xx.xx.xx.xx, how can I get acc.so to send the final resulting URI (15615551212(a)xx.xx.xx.xx) in the Called-Station-Id AVP? rad_recv: Accounting-Request packet from host xx.xx.xx.xx:39216, id=97, length=298 Acct-Status-Type = Start Service-Type = Sip-Session Acct-Terminate-Cause = 200 Error-Cause = Invite User-Name = "1000(a)xx.xx.xx.xx" Calling-Station-Id = "sip:1000@xx.xx.xx.xx" Called-Station-Id = "sip:30@xx.xx.xx.xx;user=phone" Sip-Translated-Request-URI = "sip:949449852150#15615551212@gateway;user=phone" Acct-Session-Id = "000d2890-d47f01e8-1dcc30bc-7a49c7a4(a)yy.yy.yy.yy" Sip-To-Tag = "230383F4-2AF" Sip-From-Tag = "000d2890d47f20f54576a906-290bdc33" Sip-CSeq = "102" NAS-IP-Address = xx.xx.xx.xx NAS-Port = 5060 Acct-Delay-Time = 0 rlm_sql (sql): Reserving sql socket id: 12 rlm_sql (sql): Released sql socket id: 12 Sending Accounting-Response of id 97 to xx.xx.xx.xx:39216 rad_recv: Accounting-Request packet from host xx.xx.xx.xx:39216, id=98, length=292 Acct-Status-Type = Stop Service-Type = Sip-Session Acct-Terminate-Cause = 200 Error-Cause = 8 User-Name = "1000(a)xx.xx.xx.xx" Calling-Station-Id = "sip:1000@xx.xx.xx.xx" Called-Station-Id = "sip:30@xx.xx.xx.xx;user=phone" Sip-Translated-Request-URI = "sip:949449852150#15615551212@gateway:5060" Acct-Session-Id = "000d2890-d47f01e8-1dcc30bc-7a49c7a4(a)yy.yy.yy.yy" Sip-To-Tag = "230383F4-2AF" Sip-From-Tag = "000d2890d47f20f54576a906-290bdc33" Sip-CSeq = "103" NAS-IP-Address = xx.xx.xx.xx NAS-Port = 5060 Acct-Delay-Time = 0 Thanks in advance!

[Serusers] Am I looking in the wrong place for SEMS?
by sip 15 Nov '05

15 Nov '05

I thought I'd regrab code for SEMS lately and make sure I had the most up to date source, but I noticed the sems.berlios.de page is conspicuously blank. Has the page for SEMS been moved somewhere? While I'm at it, does anyone know of a conference-capable application (hacked SEMS, Asterisk, other) that does multicast RTP? Just playing around with a few ideas, so I was curious if anyone's run across one or two. N.

[Serusers] Usrloc question
by Darren Nay 15 Nov '05

15 Nov '05

Hey all, I have a question regarding usrloc. I have run into a problem.. We have static routes sent to an asterisk server for all of our SIP usernames. In addition our IAD's will register with the same username, so that calls coming into our switch for that username will be routed to both the asterisk box and the SIP IAD. This way, whichever endpoint (IAD or asterisk) answers the call first will take the call. For example. root:/ # serctl ul show +18646404810 <sip:+18646404810@192.168.1.60>;q=1;expires=-1012151 <sip:+18646404810@192.168.1.157:5060>;q=;expires=403 192.168.1.60 is the asterisk server. This is a static route added by serctl. 192.168.1.157 is my IAD which registers with the switch every 10 minutes. So when calls are made to (864) 640-4810 then SER will send an INVITE to both location. I explained all of this just to explain now what my problem is, and ask if anyone may know a possible solution. Now, we also use asterisk to perform call fwd'ing functions. Asterisk will answer the call and then originate another call out back to SER to a new location. Now the problem! (finally!) This call fwd'ing method works very well in most cases, except that if the call fwd'ing is being sent to another location registered with SER then it will be redirected back to asterisk again, albeit to a different URI, and asterisk will kill the call because it thinks that it has looped (which I guess it has. sort of). So, I'm wondering if there is possibly a way to retrieve only the usrloc locations that don't contain the IP address 192.168.1.60 in the contact URI? This way I can just check if the src_ip is 192.168.1.60 and if so then retrieve all the usrloc locations - without asterisk - and the call will not be redirected back to asterisk. Is this possible? Or if anyone has any other ideas that may help then I am definitely open to suggestions. Thanks for your help!! Darren Nay Ionosphere, Inc VoIP Network Development dnay(a)ionosphere.net

[Serusers] Info on t_fork();

Dear Serusers: I cannot seem to find information on t_fork. There is only a small reference to it the the TM.so documentation, but no description of t_fork itself. Does anyone know where I can find information about this? Leo P.

Hi, We are trying to forward INVITE to SEMS and play announcement. It doesn't play anything. The UA which is sending INVITE is getting time out But the same .wav file for announcement if I open from sound recorder manually ,then it plays. How to check that there is problem with codec ?

[Serusers] [Help] Setting up SER in Redirect mode
by anonymous anonymous 15 Nov '05

15 Nov '05

Hello all, I am a student currently studying SIP with SER on a Slackware 10.2 system. I could have my test network working fine in proxy/registrar mode but I am having trouble in configuring SER for redirect mode. Actually I am totally new at SER administration and don't feel really comfortable in implementing code blocks into ser.cfg When I use the following ser.cfg file, SER simply ignore the redirect block and call alice at 192.168.1.2 whereas the call should be redirected to 192.168.1.4 I've been driftng all around the Internet gathering hints and tips for a few days but I'm still at that point. I guess it's a programming problem but can't find what's wrong exactly. Thank you in advance for your help.
