[Serusers] Capture REDIRECT and BLOCK messages

by Steve Morard

Hi ! I'm wondering if there is a way to capture the REDIRECT messages and BLOCK messages created by SER ( we are using CPL to make decisions when an INVITE arrives ) and to store them in a database. Thank you Regards Steve

RE: [Serusers] How to use record route to change path of BYE messages

by İlker Aktuna (Koç.net)

Hi, Thanks for your reply but this is totally a different case. In my case the problem is not CANCEL messages but BYE and ACK messages. BYE message (and also ACK) is sent to the contact of the RTP stream instead of the SER proxy. But I want these messages to be sent to SER. That's why I should somehow make them to be sent to SER. So It should be done by either recording route or changing contact header. How can I do that ?

[Users] limiting number of calls per user

by Jayesh Nambiar

Hi, I was tring to limit the number of simultaneous calls a single user can recieve in openser. I am planning to keep a column in preferences table where his max number of calls will be mentioned and as and when an Invite goes to his uri, the value will be decremented and the value will be incremented again when the bye is received for that particular call. If the value becomes '0' he can receive no more calls. But there is also a possible issue where in if a bye is not received for any particular call due to any reason, the call would be on forever and his max_calls value will not be incremented again. First of all, can this idea be implemented using avps efficiently and what would be the overhead?? If it can be implemented, how can we overcome the issue of missing byes..... Can someone already tried this feature help me or guide me to go ahead with this idea. thanks.... jayesh. --------------------------------- Yahoo! India Answers: Share what you know.

[Serusers] ReINVITE logging query

by sip

So... currently, we use a query modified from the one provided by the ever helpful Olivier Taylor to get CDR-like call-log info from SER's acc: SELECT t1.from_uri as Caller, t1.to_uri as Callee, TIMEDIFF(t2.time, t1.time) as Duration, t1.time as CallDate FROM acc t1, acc t2 WHERE t1.sip_callid=t2.sip_callid AND ((t1.fromtag=t2.fromtag AND t1.totag=t2.totag) OR (t1.fromtag=t2.totag AND t1.totag=t2.fromtag)) AND t1.sip_method='INVITE' AND t2.sip_method='BYE' AND t1.from_uri='<username>' ORDER BY t1.time DESC; It works really well with one glaring problem.... reINVITES get logged as separate calls. We see a lot of these going through FWD and our PSTN stuff and several other providers we peer with, and it becomes weird. For instance, a normal call... userA --> proxy --> userB Works really well UNLESS there's a reINVITE from userB to userA for a direct path. In that case, for a 10-second call, we get call logs that looks like: Outgoing: uriA | uriB | 00:10 | 2006-04-04 13:34:48 Incoming: uriB | uriA | 00:10 | 2006-04-04 13:34:48 The same call is logged twice as it logs both the INVITE outgoing and the incoming reINVITE. Can anyone think of a query that would strip the reINVITEs? Or are we likely going to have to do something programatically to get rid of these? Thanks, N.

[Serusers] How to use record route to change path of BYE messages

[Users] extra accounting and exported pseudo variables

by Klaus Darilion

Hi! I'm trying to extra account exported pseudo variables. should this work? modparam("acc", "db_extra", "source_ip=$si;source_port=$sp;received_ip=$Ri;received_port=$Rp;tls_peer_subject=$tls_peer_subject"); nomal logging is fine: xlog("L_INFO","[$Tf] $$tls_peer_subject = '$tls_peer_subject'\n"); results in: [Wed May 3 16:11:52 2006] $tls_peer_subject = '/C=at/ST=Vienna/L=Vienna/O=itsp2/CN=itsp2.labs.nic.at But the accounting fails: ERROR:acc:extra2strar: failed to get 'tls_peer_subject' Is there a known problem? Is it because when the accounting is done, there is no more TLS connection available to retrieve the cert parameters? Meanwhile I will try the workaround with copying to AVPs and accounting of the AVPs. regards klaus

[Serusers] ser and History-Info (RFC 4244) for VM/UM application

by john hess

hi, does anyone have experience in using ser in processing call-forwarding/redirection signaled in the History-Info section (as per RFC 4244)? the application context is ser as a means to interpolate signaling between an IP PBX and a SIP-speaking VM/UM platform (I3 Communite -- v2.3.1). the problem i am trying to solve (at least in the near-term) is that the PBX is using History-Info to signal call-forwarding events (ex: CFNA, CFB) while Communite is expecting call-forwarding to be signaled via Diversion. until the platforms support have a call-forwarding signaling method in common, i would like to be able to insert ser into the signaling path -- more or less as a translator between the two platforms. tia, john john hess <jhess(a)berkeley.edu> nocman ist, uc berkeley 510 643-6401

[Serusers] SER pa and XCAP server

by Miguel Freitas

Hi all I'm trying to get a SER with pa, rls and mysql modules to test it as a XCAP server, along with Apache2 webserver and eyeBeam softphone... At start, I ran into lots of info how to do it, and the presence handbook seamed to be a good way to start. I came across http://download.dns-hosting.info/XCAP/ which could get me where I wanted (but there's no reference to which version of SER used). But it was only the beginning of a long and hard struggle! I downloaded the sources ser-0.10.99-dev35-pa-4 from http://ftp.iptel.org/pub/ser/presence/ but I didn't manage to install it, later I realized that maybe I shouldn't be using the gcc 4. So I moved on to the debian packages, but there isn't a release of the rls module! So I moved on to the sources of the latest release, ser-0.9.6. Still no rls module, I got it from ser-0.10.99-dev35-pa-4. But it has been a nightmare to config the ser.cfg because the module pa doesn't support some of the functions described on the presence handbook.. I abandoned ser-0.10.99-dev35-pa-4 because, among other things, the tool serctl was working with the older version of the SER database (trying to add new users to ser.subscriber instead of ser.credentials) I could use some pin-points to where I should go now, if stick with ser-0.9.6 or move again to ser-0.10.99-dev35-pa-4 since it should be more what I'm looking for. Thanks for any help ubuntu 5.10 gcc 3.4.5 MySQL 4.1.12 (libmysqlclient14-dev) Apache 2.0.54 (libapache2-mod-suphp, libapache2-mod-php4, php4-pear, php4-cgi)
