Hi everybody, I just committed on CVS full support for per-branch flags. What's the difference between the flags we already have and these new one? So far we ave in OpenSER flags that will be called "global" flags - global because they were visible everywhere in the transaction (in all routes and in all sequential replies/request). The new flags, called "branch" flags are flags that will be visible only for a specific branch - in all replies and routes connected to this branch. For example: I have a call parallel forking to GW and to a user. And I would like to know from which branch I will get the final negative reply (if so). I will set a branch route before relaying the calls (with the 2 branches). The branch route will be separately executed for each branch; in the branch going to GW (I can identified it by looking to RURI), I will set a branch flag. This flag will appear only in the onreply route run for replied from GW. It will be also be visible in failure route if the final elected reply belongs to the GW branch. This flags will not be visible in the other branch (in routes executing replies from the other branch). how to use it? The request flags may be split in two arrays - globals and branch flags - by using the TM parameter "branch_flag_mask" (see http://www.openser.org/docs/modules/0.10.x/tm.html#AEN268). Flags covered by this mask will be processed as branch flags, the rest of them as global flags. Also, modules may set branch flags before transaction creation (for the moment this feature is not available in script). The REGISTRAR module is the first to use this feature. If the "use_branch_flags" param is enabled (see http://www.openser.org/docs/modules/0.10.x/registrar.html#AEN236), the NAT flag will be push in branch flags instead in message flags - IMPORTANT: be sure that NAT flag is in the range of the branch flags ad defined in TM. Using this, NAT traversal per branch may be experimented.... regards, bogdan

[Serusers] NAT Related Voicemail Timeout Problem (HELP!)

by Corey S. McFadden

We're working through an annoying problem with voicemail and the fr_inv_timer and after banging our heads against it for a while figured we'd reach out for a little help. It's probably something obvious, but here's the scenario: 1. SIP DID rings SER 2. SER Routes to registered UA (UA behind NAT) 3. UA Rings 4. fr_inv_timer is hit and failure_route[1] is invoked 5. failure_route[1] rewrites host to send call to Asterisk for VM 6. Asterisk gets the call and starts processing but the calling party never gets the OK, gets no audio, and dies with a fast busy. When the UA is NOT registered or registered without going through NAT there isn't a problem. Asterisk OK's and works fine. This is probably some moronic NAT issue but we're not sure how to proceed. I'm going to follow with a 'sip debug' message from Asterisk, some ngrep from the SER machine (with commentary), and finally the SER cnf itself. If anyone can help we would be incredibly grateful! (Seriously!)

[Serusers] Cacheless usrloc module

by Andreas Granig

Hi, I'd like to announce an experimental module for SER-0.9.x which provides a cacheless user location implementation. It's fully compatible with the original usrloc module (well, in fact you have to apply a small patch to assure full compatibility, but this patch doesn't hurt if you switch back to the original usrloc module). It currently only supports MySQL as backend because some MySQL specific queries are used. Also the watcher/callback API isn't tested, so you currently better not use it in combination with the pa module. You can find the module and a short howto here: http://linguin.org/ser.php#usrloc_db Please note that this module is very experimental. Any feedback is highly appreciated. Andy

[Serusers] new pa entry in serctl usage menu

by Aisling

Hello, I recently upgraded to ser 0.9.3 and I noticed that there's a new entry in the serctl usages document: pa pres <p_uri> <pstate> .......set pstate for a presentity pa loc <p_uri><loc>.........set a location for a presentity Am I correct in assuming that the first command allows a a subscribers "availability" or presence state to be set? i.e. "busy", "unavailable" etc or is this limited to "online", "offline"? Also with the second command, does this represent something like a presentities current location i.e. office etc? If not, what does it represent or how should it be used syntactically? Based on my assumptions above, I tried "serctl pa loc aisling(a)x.x.x.x office" and the following errors occurred (SER was also killed): submit_query(): Unknown column 'pdomain' in 'where clause'. submit_query(): Error while submitting query pdomain_load_presentities: Error while querying presentity submit_query(): Unknown column 'pdomain' in 'where clause'. submit_query(): Error while submitting query new_presentity: Error while querying presentity child process 10644 exited by signal 11 core was generated INFO: signal 15 received INFO: signal 15 received INFO: signal 15 received INFO: signal 15 received Etc etc BUG: shutdown timeout triggered, dying..

[Serusers] Connecting to Mysql

by Adam King

Hi I am have a problem connecting to the MySql database. I am running Fedora Core 3, ser 0.8.12 (i386/linux), mysql Ver 12.22 Distrib 4.0.24, for pc-linux-gnu (i686). In ser.cfg I have chosen to use the MySql database, and attempt to authenticate using either of (I have tried both at seperate times): modparam("auth_db", "db_url", "sql://root:XXXX@localhost/ser") modparam("auth_db", "db_url", "sql://ser:heslo@localhost/ser") both of which result in: 0(4971) connect_db(): Access denied for user: 'ser@localhost' (Using password: YES) 0(4971) db_init(): Error while trying to connect database 0(4971) mod_init(): Error while connecting database 0(4971) init_mod(): Error while initializing module usrloc However: # mysql -user -p Enter password:heslo AND # mysql -user -p Enter password:XXXX both work. Even if I attempt to connect using sql://root:XXXX@localhost/ser, do I get access denied to user ser? I have not changed the default password 'heslo' for the ser mysql user yet. I have also not changed the DEFAULT_DB_URL in config.h. I presume this is not a bug in SER or anything like that however, and teh credentials are correct on the MySql side, so I am stuck. Does anyone have a suggestion? Thanks in advance Adam

Next, i install the mysql from mysql-standard-4.1.12-pc-linux-gnu-i686.tar.gz according to the INSTALL-BINARY document. then i start the ser , cd /usr/local/sbin ser_mysql.sh create ser the problem is while i use "serctl add tieban 123456 tieban(a)sina.com",it prompts me that: $ serctl add viking 123456 tieban(a)sina.com MySql password: error: 400; check if you use aliases in SER How can i to make it, any suggestions will be appreciated. thx. 　　　　　　　　viking 　　　　　　　　tieban(a)sina.com 　　　　　　　　　　2005-09-02

[Serusers] NAT Router problem

by Rick Thompson

Has anyone come across this problem before?? I have the same configuration for each of the following except the first session is going thru a Linksys router and the second one goes thru a Dlink router. The first session works fine, the second session has one way audio. The only difference in the traces is in the following lines.

[Serusers] BYE's not accounted

by Ashutosh Kumar

HI, My BYE's are not getting accounted in the mysql DB, though all other messages are getting reflected. I have put setflag for all messages, at the beginning of cfg. My relevant ser.cfg code is following. ..... ..... if (loose_route()) { if (has_totag() && (method=="INVITE" || method=="ACK")) { if (client_nat_test("3") || search("^Route:.*;nat=yes")) { setflag(6); use_media_proxy(); }; }; route(1); break; }; setflag(1); ..... ..... Please guide. Regards, Ashutosh Kumar
