[OpenSIPS-Users] B2BUA Transfers Intermittently Working/Not Working (Bug?)

Thu Oct 28 23:39:03 CEST 2010

Got it. 

I've updated the MySQL table and started OpenSIPS (which is version 1.6 from the SVN head). I tried the calling again (with 2 transfers) and I now see the 202 Accepted message which is correct, but the second transfer is still failing with the same error:

The call trace shows that OpenSIPS is not originating the new call leg out to the phone that the call was transferred to (probably because of the error above). I don't see any errors in the call trace with regard to the REFER message (or any others) sent by the phones. The REFER looks the same with different extensions for the first transfer and the second transfer. It seems like OpenSIPS is just not handling the second transfer correctly.

Hi Brett, 

You should have used the script in scripts/mysql/b2b_create.sql . What you have missed is inserting in version table the version number for the new tables 
INSERT INTO version (table_name, table_version) values ('b2b_entities','1'); 
INSERT INTO version (table_name, table_version) values ('b2b_logic','1');

Hi Anca, 

I tried to install from the 1.6 branch and I am getting errors about the database version for b2b_entities:

Oct 27 15:45:30 sip01 /usr/local/sbin/opensips[15672]: NOTICE:presence:destroy: destroy module ... 

I used /usr/local/sbin/opensipsdbctl create to make the tables. 

Is there information available that would tell me what modifications I need to make to the b2b_entities table for it to work properly?

Hi Brett, 

Sorry, I was mistaken, I tested wrongly with 1.6 the first time. It does work with 1.6 also, you can update from the 1.6 branch and check.

Hi Brett, 

I have just tried your scenario with trunk and I see the 200 OK reply. I have checked with 1.6 and indeed it seems to be a problem. I think I will backport the changes in these two modules - even though they are quite a lot, but there is no point in debugging on old code when this problem is fixed. 
So, I suggest for you to update from trunk, at least these two modules - b2b_entities and b2b_logic. 
Be aware that you will have to install the database tables also.
