[Serusers] problem with MESSAGE and un-REGISTER
by KUMAR 11 Jun '07

11 Jun '07

hi all, I've started using SER 2.0 rc1 and am having a bit of problems with UA behind NAT. I'm using Windows Messenger 5.1 as the UA. Everything works fine when both UAs are not behind NAT. But when I place one of the UAs behind NAT, then, here's what happens, in this order UA Behind Nat ----------MESSAGE------>UA outside NAT..............ok UA outside NAT-----------MESSAGE------->UA behind NAT.............OK UA behind NAT------------MESSAGE------->UA outside NAT.............message is stored by msilo module and sent after some time. The log shows: MSILO: the downstream UA doesn't support MESSAGEs Notice that this only happens once a message from outside of NAT is sent to UA inside NAT. I am using RTP Proxy for NAT solution which is on the same system as SER. Moreover, I also cannot signout using the Windows Messenger. However, when I tested using XLite, None of the above mentioned problems arose. Can anyone please suggest me as to where the problem might be. The ser.cfg that I'm using is the one from the iptel site, the one with NAT & RTPproxy. I am also attaching the ser.cfg. Thank you in advance. Kumar

[Serusers] Presence pa module - no NOTIFY messages sent
by tzieleniewski 11 Jun '07

11 Jun '07

Hi, I am using SER rel_2_0_0. I am trying to set up a presence server as a simple PA. I am using xlite UA and when UA registers and subscribes to a particular user presence Event SER doesn't sent a NOTIFY according to the 'time_interval' module parameter. It only responses with the 'immediate NOTIFY' with the closed status tuple. According to my configuration SER should sent a NOTIFY every 15 seconds and it doesn't do it at all. I kindly ask for your feedback. Below I attached my module configuration and messages exchanged with UA. # -- pa params -- modparam("pa", "default_expires",300) modparam("pa", "max_subscription_expiration", 3600) modparam("pa", "max_publish_expiration", 3600) modparam("pa", "use_db", 1) modparam("pa", "use_callbacks", 1) modparam("pa", "watcherinfo_notify", 0) modparam("pa", "use_offline_winfo", 0) modparam("pa", "offline_winfo_expiration", 259200) modparam("pa", "auth", "none") modparam("pa", "winfo_auth", "implicit") modparam("pa", "pres_rules_file", "presence-rules.xml") modparam("pa", "ignore_408_on_notify", 0) modparam("pa", "timer_interval", 15) modparam("pa", "default_priority_percentage", 0) modparam("pa", "auth_rules_refresh_time", 300) modparam("pa", "async_auth_queries", 1) modparam("pa", "max_auth_requests_per_tick", 600) # U 2007/06/04 16:52:16.423720 192.168.0.229:7060 -> 192.168.0.165:5160 SUBSCRIBE sip:sen@voip.rd.touk.pl SIP/2.0.

[Users] Insert a Header into ACK message
by fancy 11 Jun '07

Dear All: I've tried many methods to add Max-Forwarsd header into ACK message (message 8), all methods I tried were fail. According to RFC 3261 8.1.1.6, Max-Forwards must exist in this ACK message. Can anyone tell me how to add a header into ACK message? Thank you very much. UA11 : NUT(Proxy 1) : UA12 | : | : | |-------:------->| : | 1.

[Users] A question about header insertion...
by nick 08 Jun '07

08 Jun '07

I'm trying to insert a Remote-Party-ID header into my INVITE messages, but I'm finding that when I do so, it's ending up further down in the message than it should be. After the Content Type header in fact. How is it decided where to insert the header, is it based on the time that the insertion of the header happens during the processing of the invite? Can I specify that it be inserted before the content type header in some way? (I didn't see this as an option..)

[Users] Dispatcher crash OpenSER
by Federico Cabiddu 08 Jun '07

08 Jun '07

Playing with my dispatcher configuration (openser-1.2.1) I discovered that ds_select_dst() crashes openser when dispatche param ds_use_default is set to 1 and the set from where the destination is picked up contains just one address. This appens because in dispatch.c at row 784 the code is if(ds_use_default!=0) hash = hash%(_ds_list[idx].nr-1); else hash = hash%_ds_list[idx].nr; so if ds_use_default is set and the address set has 1 destination the % causes a crash. To avoid this it's enough to modifiy the if statement like: if (ds_use_default!=0 && _ds_list[idx].nr!=1) Just my two cents.

[Users] null script variable value in tw_append
by jh＠tutpro.com 08 Jun '07

08 Jun '07

if i have modparam("tm", "tw_append", "params:P-X=$avp(i:100);P-Y=$var(foo)") and assign null to both $avp(i:100) and $var(foo) before t_write_unix(), then P-Y is appended (with value 0), but P-X is not. in my opinion, also P-Y should not be appended, i.e., script variable value null should be treated the same way as pseudo variable null value. -- juha

is it somehow possible to unset a script variable? i'm not absolutely sure, but looks like script variables can retains their values from processing of one request to another so it is important to be able to reset them. -- juha

[Users] Help on probably memory leak
by Marcello Lupo 08 Jun '07

08 Jun '07

Hi to all, i converted my config from 1.0.0 version (workng like charm) to 1.2.0 and started to test the 1.2.0 version. I started to get out of memory message in the logs from this morning on the test proxy i have till it involved all the threads and the proxy stop working. It is an openser-1.2.0-notls and is almost unloaded because it is under simple testing. I think this is the reason it worked a lot of days before get the problem. I followed instructions on wiki and recomplied openser with memory debug options. I attach you the link to the output of logs, memory debug and some other useful informations because i'm absolutely not able to understand where can be the problem (i'm not a coder). http://82.193.22.211/memory_leak.txt The errors in the file are previous to the recompilation of openser with memory debug option enabled. Now from the restart of the process still no errors but i think it is for the very low load of the server. May be you can already found some memory leak in the memory debug log. If you can help it is very appreciated. Thank you to all. Bye, Marcello
