Hi Mr. Castillo, I tried it, but don't work. My problem is: - Each Register created by X-LITE 3.0 is a new contact because each message have parameter RINSTANCE with new value. - So OpenSER will keep in your location table all the contacts received. - I want break it, so for each Register Message Openser will update this contact in your location table. My location table (Replace My Ip Number to xxxxxxxxxxxx): id | username | domain | contact | received | path | expires | q | callid | cseq | last_modified | flags | cflags | user_agent | socket | methods ----+----------+--------+-------------------------------------------------------------+----------+------+---------------------+------+----------------------------------------------+------+---------------------+-------+--------+----------------------------------+--------------------------+--------- 36 | teste1 | | sip:teste1@xxxxxxxxx:27420;rinstance=457f14a9ad568c74 | | | 2007-11-14 16:54:05 | 0.00 | YjY5YmFkZDRkZjBmOTliOWFiNmY2ODViMmRmMTg3ZjQ. | 2 | 2007-11-14 15:54:05 | 0 | 0 | X-Lite release 1011s stamp 41150 | udp:xxxxxxxxxxxx:5060 | 5951 37 | teste1 | | sip:teste1@xxxxxxxxxxxx:9150;rinstance=d491e76ae7d17c63 | | | 2007-11-14 17:01:09 | 0.00 | OTdiNDM4Y2M4NWEzMjIwMmU5MWE1Y2E5M2E3N2VkNjY. | 2 | 2007-11-14 16:01:09 | 0 | 0 | X-Lite release 1011s stamp 41150 | udp:xxxxxxxxxxxx:5060 | 5951 38 | teste1 | | sip:teste1@xxxxxxxxxxxxx:32448;rinstance=a88d552b74e3ebbc | | | 2007-11-14 17:07:13 | 0.00 | ZTE4YTE4OTVlOGJjYTExM2IxM2RiZjFlOGMyNzI3Nzk. | 2 | 2007-11-14 16:07:13 | 0 | 0 | X-Lite release 1011s stamp 41150 | udp:xxxxxxxxxxxx:5060 | 5951 Then this problem is just with X-LITE 3.0 Already talked with CounterPath' Support and this error is knowledge them and in the next version will be removed. But still in demo this new version, and will need long time to be released. Wait your help.

For this you should, in each REGISTER, do a DB query (or FIFO command) to test if there was a previous entry for this location, and in that case modify the "methods" field of new entry: http://openser.svn.sourceforge.net/viewvc/openser/trunk/parser/msg_parser.h… -- I?aki Baz Castillo ibc(a)in.ilimit.es -- ---------------------------------------------------------------- THIAGO MALUF RESENDE e-mail: malufrj(a)gmail.com
