[Serusers] Using SER with Microsoft OCS 2007
by Nolan Garrett 02 Jan '08

02 Jan '08

Hello! I am interested in using SER to convert TCP SIP traffic from OCS to UDP SIP traffic that I can use with an external PSTN gateway provider. Has anyone successfully managed this? Basically, the configuration would look like OCS -> Mediation Server -> SER -> External Provider Would the Mediation Server still need an external (non-NAT'd) IP? It seems like it would, unless I use mediaproxy or RTPproxy, which would add an additional layer of complexity. I guess I am looking for some validation that what I am trying to do will work. My next question, which I can't seem to find an answer to, is how I take the TCP SIP traffic from OCS, convert it to UDP SIP, and also authenticate with that external provider. Any ideas on how to use t_relay_to_udp with authentication? Thank you! Nolan

[OpenSER-Users] Some issues with Session-Timer module
by Franz Edler 31 Dec '07

31 Dec '07

Hi, I have just made some tests with sst-module (OpenSER v1.3) and I found the following two issues: I case the min-se value of sst-module is higher than the Session-Expires header field of a received INVITE OpenSER rejects the INVITE request with 422 response (that's as expected). But: 1. the Min-SE header field in 422 response (packet 18 in attached trace) does not end with CR/LF so that it is concatenated with the next header field (Server header) syslog prints in this case: ERROR:sst:sst_dialog_terminate_CB: DID 0xb5582d80 failed (canceled). Terminating session. 2. OpenSER in addition continues to forward the already rejected INVITE transaction with "100 Giving a try"(packet 19) and forwards the INVITE to the UAS (packet 20). The next issue I discovered is with the UAC (Xlite): The repeated INVITE (caused by the 422 Response) does not increment the CSeq header field so that it is regarded as same request leading to a "482 Merged request" rejection at the UAS (Eyebeam). I have attached the tcpdump-trace and the according SIP-scenario trace. Any comments appreciated. Regards Franz

[OpenSER-Users] dialog module: dialog data remain in DB after "dlg_end_dlg"
by Franz Edler 29 Dec '07

29 Dec '07

Hi, I just found that after forced end of a dialog (MI command "dlg_end_dlg") the dialog data remain in the database. The dialog list in memory (MI command "dlg_list") is cleared after forced end of a dialog as expected. Shouldn't the dialog data in the DB also be deleted? Regards Franz

[OpenSER-Users] ERROR:avpops:check_avp: value types don't match
by Jayesh Nambiar 28 Dec '07

28 Dec '07

Hi All, I am using the function avp_db_query to query a table and fetch few values. The query is as follows: "select subscriptionid, ip, media_status from domestic where prefix=$rU", "$avp(i:101), $avp(i:102), $avp(i:103)". Now the media_status column is a column with datatype as integer which will contain either 0 or 1. I need to check the value in this column so I use the following: if(avp_check("$avp(i:103)", "eq/0/i")) { do certain things; } else { do certain things; }; Even when the value at media_status column is 0 it does not get into that condition, it always executes the else condition and I see the following in the logs: ERROR:avpops:check_avp: value types don't match Can someone please help me to overcome this error. When I keep the datatype of media_status column as varchar it works fine, but I dont want to do that as that column is going to conatin only integer values. Thanks in advance. w/regards, Jayesh Now you can chat without downloading messenger. Go to http://in.messenger.yahoo.com/webmessengerpromo.php
