[Users] CPU load, ERROR: append_branch: max nr of branches exceeded, etc..
by Dan Mechanic 24 May '07

24 May '07

Forgive me if this question is a little open-ended... I am new to openser and sip, and trying to learn all I can... I am looking for information regarding: ERROR: append_branch: max nr of branches exceeded I understand that this error can be avoided by increasing the value of MAX_BRANCHES and recompiling openser, but, I am curious as to what happens when this error has been reached. Here's our situation... We use openser, and have a separate openser presence server. We had a situation recently where it seemed our presence server was bombarding our proxy to the point where the load on the proxy jumped and phones became unusable. Taking down the presence server seemed to alleviate the troubles. Also, we have an intermittent issue with phone reboots and lost calls, particularly on extensions that are on more than 12 phones (MAX_BRANCHES is currently set to 12). So, my question is, is this failure (max nr of branches exceeded) an innocuous one? or could it lead to futher failures (and maybe sip message recents... thus the bombardment)... Are there known side affects of this failure? Any info would be appreciated. Thanks Much! Best, Dan Mechanic

Hi, After many many months of faultless operation, today we experienced a SEG FAULT on one of our proxies running OpenSER 1.1.0-notls: Below is a back trace (with some values masked with xxx's), however our initial analysis can not make any sense of what the problem is. Any ideas would be greatly appreciated. res.c:194 is =====> r = (db_res_t*)pkg_malloc(sizeof(db_res_t)); Here is the back trace: (gdb) bt #0 0x00000000 in ??

[Users] Content-Lenght problem with NOTIFYs
by Tobias Lindgren 23 May '07

23 May '07

Hi all, a customer of ours are having some trouble with the Content-Lenght header when a NOTIFY-message goes through our OpenSER 1.2.0. Here is what seem to happend. SIP NOTIFY from our PSTN-gateway to our OpenSER: --- CUT --- Content-Length: 21. . SIP/2.0 100 Trying. . --- CUT --- SIP NOTIFY from our OpenSER to Customer: --- CUT --- Content-Length: 21. . SIP/2.0 100 Trying. --- CUT --- Now, the customer has to manually do this in his OpenSER to make the UA on his side happy: if (method=="NOTIFY") { if (search_body("SIP/2\.0 100 Trying")) { xlog("L_WARN", "R: Setting Content-Length to 20\n"); remove_hf("Content-Length"); append_hf("Content-Length: 20\r\n"); } } Please advice on what we are doing wrong here? Br, /Tobias

Hi all, this is my first email to this list. hoping to mingle with you all from now on. I have been working on asterisk for about a year. Now my company is planning to use openser with asterisk having asterisk at backend for features and voicemail. So is there any book for starters for openser as there is for asterisk (Asterisk the future of telephony). i need a book or any helpfull link which should reveil the basic concepts of openser, how to install it, how to program it, and how to manage it. Thanx in advance -- Rizwan Hisham Software Engineer AXVOICE Inc.

[Users] dispatcher question
by Klaus Darilion 23 May '07

23 May '07

Hi! Let's assume I have a load balancer which distributes (using hash over R-URI) calls to 4 proxies. Further, ds_mark_dst() is used to marked broken proxys. Marking a destination as inactive - does this change the routing completely (as if there were only 3 proxies in the config file) or will it still hash over the 4 proxies, but choose automatically the second entry in the resulting list if the result is the inactive proxy? regards klaus
