Re: [OpenSER-Users] Tech prefix and CarrierRoute

Hi, the actual rewrite is done in the route_func.c:actually_rewrite() function. The rewriting URI action is done in the carrier_rewrite_msg() in the same file. But why can't your billing server just evaluate the call-id header field that is probably present in the SIP message header? This would be much more easier then to hack the module code in my opinion.

[OpenSER-Users] ERROR: couldn't open sequence file /var/run/radius.seq
by Iñaki Baz Castillo 13 Feb '08

13 Feb '08

I see this issue in syslog: ---------------- openser: rc_get_seqnbr: couldn't open sequence file /var/run/radius.seq: Permission denied --------------- The problem is that OpenSer run with "openser" user who has not write access to /var/run. If I change permissions to /var/run the the message doesn't appear. Anyway I'd prefer not to modify permissions and owner of a system directory as /var/run. - How important is that "radius.seq" file? - Is not possible to configure OpenSer to write it in /tmp (for example)? Thanks. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

Re: [OpenSER-Users] FreeRADIUS-CDRTool Prepaid Connector 1.1 Released
by A.smith 13 Feb '08

13 Feb '08

Hi Dan, Thanks for the all the info! Ok, question on this part: 3. Accounting it is bit more accurate (you have the session total duration inside the accounting packets), so radius will be no longer responsible of calculating the session durations from timestaps. To interoperate with CDRTool you still need the data in the radacct table formatted as per normal by Freeradius, right? By accouting packet are you referring to the radius accouting packets? If you say Yate puts session times in the accouting packets how does this all stick together? Does OpenSER still do the radius accouting part, or do I need to configure Yate to do it instead? thanks a lot! Andy. --------- Original Message -------- From: Dan-Cristian Bogos <danb.lists(a)googlemail.com> To: A.smith <a.smith(a)ukgrid.net> Cc: users(a)lists.openser.org Subject: Re: [OpenSER-Users] FreeRADIUS-CDRTool Prepaid Connector 1.1 Released Date: 13/02/08 12:15 > Hi Andy,The original config was built with Yate in mind due to openser incapacity (before release 1.3) of disconnecting the calls. Since 1.3.0 the dialog module should be able to timeout the calls, in theory you should no longer need extra software like Yate. > I would still recommend using Yate combined with OpenSER in the case you are doing some sort of "Carrier business", for  the following reasons:1. It creates two different legs for your call (in and out) same as Cisco does, and hides one side from the other (eg. removes the via headers and any revealing ip information inside SDP - so your partners should not know where the traffic comes from). > 2. You have more protocols available in.3. Accounting it is bit more accurate (you have the session total duration inside the accounting packets), so radius will be no longer responsible of calculating the session durations from timestaps. > 4. Yate can work in rtp_forward mode, therefore no extra overhead given by rtp processing.So basically what the connector does (as specified in the documentation), for each call which is authorized by radius, the connector will ask permission from cdrtool. If permission is granted, it will return in a avp to openser the maximum duration allowed for the call (timeout value) plus credit available, for the case of special uas able to display that. > By receiving accounting stop packet, the connector will inform cdrtool about call disconnection therefore clearing the lock and debiting the balance inside cdrtool. The rtp stream has nothing to do with this scenario, so you don't need to touch your NAT support configuration, it's all in the signaling. > Let me know if you need further info.Cheers,DanBOn Feb 13, 2008 12:53 PM ________________________________________________ Message sent using UK Grid Webmail 2.7.9

[OpenSER-Users] Routing Problem "To Many Hops"
by Ali Jawad 13 Feb '08

13 Feb '08

Hi All I am trying to achieve the following 1. User Calls a number * If the number is 00+all numbers go to PSTN -> Else check if the user is existent in our SIP Proxy user pool and act accordingly What I achieved so far is the following 2. User Calls a number * Route checks if the number is online if yes the call is routed to him (route[1]) if not it send the call to PSTN if it is 00+[0-9] route [2]. This works fine for 00+[0-9] number however if 123456 is called and the user 123456 is not online, the call goes down through the conditional statements because it does not meet 00+[0-9] and I get an error "To Many Hops" Seems I messed up somewhere, can anyone help me fix this http://pastebin.com/m50328c12 Thanks

Re: [OpenSER-Users] OpenSER - a slow starter?

Hi Klaus, > MAybe openser tries t do some DNS lookups which may take long time. > > The best would be to set debug=4 and "tail" to the logfile > (default=/var/log/syslog (or /var/log/messages on RedHat&co)). I was running at debug level 6 already, and dumping the output to screen. However, I actually found the error last night: Beeing new to all this, I had mediaproxy and proxydispatcher running on the machine - primarily as a proof to myself that they where installed and seemed to work. I assumed they wouldn't interfere with OpenSER as long as the support modules wasn't loaded, but alas, I was wrong: As soon as I stopped mediaproxy and proxydispatcher, OpenSER started working as expected. The problem is reproduceable - but I think it's a bit strange behaviour? Regards, Lars -- Lars Skjærlund Skovengen 111 2980 Kokkedal Denmark Tel.: +45 70 25 88 10 http://www.skjaerlund.dk/lars

[OpenSER-Users] Implementing Follow-me
by Cosimo Fadda 13 Feb '08

13 Feb '08

Hi, I'm very new to this list. In my setup I use openser as proxy an asterisk as pstn gateway. I want to implement a 'follow-me' service, i.e. I want users to dial a particular number and then they can enter a phone number where receive their incoming calls. So which is the best solution: use asterisk to perform a lookup in the DB and decide to which number route the call, ore use openser maybe with the 'exec_dset' command? Or there is a command that I'm missing that can implement this function? Thanks in advance, Cosimo -- *Ing.

[Serusers] Do an anonymous call
by inge 12 Feb '08

12 Feb '08

Hi all, I've implanted this feature some months ago and it no longer appears to be functional. To do that I have used a subst function to parse and replace sip:XXX| <sip:XXX> by "Anonymous" sip:|<sip:>. It follows to run on some products but not on an other one and only between them (ie. on-net between the products concerned). If someone can help me/guide me. Thanks ! Regards, Adrien
