[Serusers] ser-0.9.6: modules/postgres bugreport & patch

by Alexandre Snarskii

Hi! I'm running ser-0.9.6, on FreeBSD 6.1-stable, database backend is postgresql version 8.1.3. Today I got errors in logfiles, saying: messages.2.bz2:May 29 14:35:03 <XXX> /usr/local/sbin/ser[51448]: ERROR:avpops:dbrow2avp: dbrow contains NULL fields The similar problem reported in: http://lists.iptel.org/pipermail/serusers/2005-May/019681.html with much more detailed description of error, database contents and config samples. Patch is trivial, and looks more like a fix to copy'n'paste error: in mysql/val.c function str2val states: if (!_s) { memset(_v, 0, sizeof(db_val_t)); VAL_TYPE(_v) = _t; VAL_NULL(_v) = 1; return 0; } VAL_NULL(_v) = 0; and the last line mentions that 'well, that's value is not NULL'. In postgresql/db_val.c, line 182, function str2valp, the same statement is the: if (!_s) { DLOG("str2valp", "got a null value"); VAL_TYPE(_v) = _t; VAL_NULL(_v) = 1; return 0; } without explicit notification that this is not-NULL value. More than, nowhere else in this function VAL_NULL(_v) not set to 0. So, if a value _v.val contained anyting but 0 at the function start, resulting value will be threated as NULL despite the fact, that _s is NOT NULL. Patch is obvious, just add VAL_NULL(_v)=0; after cited block (line 188) and everyting will be ok. At least for me it's ok for some hours :)

[Serusers] SER Nokia CANCEL Problem

by Abdul Qadir

Hi , I tried to call from one nokia sip (E61 and other models )phone to another nokia sip phone. The call works fine. The problem comes only when I call from Phone A to Phone B and then immediately cancel the call(from Phone A). The Phone A will hangup the call as it sent CANCEL but the SER will ignore this CANCEL and still send INVITE to Phone B resulting in a ghost call situation. I tried to capture a log of message and found that Phone A "CANCEL" message is received on SER even before any provisional response from Phone B. Therefor SER doesnot relay this CANCEL request to Phone B. I even checked RFC which clearly says that UAC should not send CANCEL untill it receives any provisional response. I talked to Nokia expert and they said the 100 Trying message from your server is considered as provisional response, therefor behaviour of client is absolutely correct. Is there any way I can stop 100 Trying message and still run statefull SER, so that I can verify what nokia said. Any ideas suggestions are welcome. Thanking you all in advance.

Dear all I have a big problem with openxcap. I don't get it work :( As I saw on their webpage, this mailing list can be posted for this concern as well.

[OpenSER-Users] uac_restore_from problem

by Zoltán Kovács

Dear Colleagues, first of all, thank you for the great software which is a very nice and convenient way to build up a stable VoIP telephone system! We already have a working system based on OpenSER and Asterisk. After many experiments I finally raise this question to you because I cannot figure out the solution. The problem described on http://www.openser.org/pipermail/users/2006-January/002747.html seems to be very similar to mine. I am using openser-1.1.0-9etch1. I tried to replace the FROM variable as follows: loadmodule "uac.so" modparam("uac","from_restore_mode","auto") ... route { ... avp_write("$fU", "$avp(s:display)"); avp_write("$fU", "$avp(s:dispuri)"); avp_subst("$avp(s:display)", "/^36(.*)/06\1/"); avp_subst("$avp(s:dispuri)", "/^36(.*)/sip:06\1@datanet.hu/"); uac_replace_from("$avp(s:display)", "$avp(s:dispuri)"); ... } Unfortunately nothing seems to happen: no change is made on several VoIP telephones, including X-Lite as well. loose_route() and record_route() were also used in my configuration. Could you please help me what I am missing here? If needed, I can also send a full config file. Thank you in advance, Zoltan Kovacs sysadmin
