Core dump error
by rex.alex 16 Feb '11

16 Feb '11

Hi I was using the FreeSWITCH 1.0.6 for quite some time in production and was very stable and recently I had upgraded to latest git to use the mod_spandsp module. From then on I used to get core dump issue sometimes and hence yesterday I did a git pull && make current on source. But today, till now FreeSWITCH has been core dumped for 5 times, could not find the reason. I have pastebin the core trace in http://pastebin.freeswitch.org/15402 Version : FreeSWITCH Version 1.0.head (git-722b2ce 2011-02-15 19-01-45 -0600) OS : Cent OS 5.5 Please help me to resolve the same. Thanks, Rex -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/Core-dump-error-tp6033400p603… Sent from the freeswitch-users mailing list archive at Nabble.com.

Sofia and SIP Service-Route header
by Žiga Jakhel 16 Feb '11

16 Feb '11

Hi! We're having issues with a >funky< ISP - they started advertising a SIP Service-Route header pointing to nowhere (go figure), claiming they need it for their systems to function, and that our UA should not use it, if the initial address is working. Sofia, however, uses the header dilligently, sending the request to the address specified in the header (in my case going nowhere), despite the functioning base SBC address. Any ideas? Is my ISP off the rocker, or is Sofia maybe a little overzealous? Regards, Žiga Jakhel, MSc Integrum d.o.o. Smoletova 6, 1230 Domžale Slovenia, EU

Re: [Freeswitch-users] g729 packets skipped in passthrough mode
by Javier Gallart 16 Feb '11

16 Feb '11

Hello, I've looked deeper into this issue and I might have hit a known problem: RTP_BUG_IGNORE_MARK_BIT = (1 << 2) /* A Huawei SBC has been discovered that sends the mark bit on every single RTP packet. Since this causes the RTP stack to flush it's buffers, it horribly messes up the timing on the channel. This flag will do nothing when an inbound packet contains the mark bit. */ The carrier is actually a Huawei SBC, and the problem I reported only happens when it sends the marker bit = true in all the rtp packets. I've tried <param name="auto-rtp-bugs" data="RTP_BUG_IGNORE_MARK_BIT"/> in the profile but the problem is still there, is this the right way to override this nonsense from the Huawei?

Persistence BLFs (or: Dear PBX please remember the BLF state)
by Patrick Plattes 16 Feb '11

16 Feb '11

Hi List :-), I'm currently switching from Asterisk to FreeSWITCH. It's really hard work for an Asterisk user, but using Asterisk becomes more and more painful even for small installations (less than 100 sip users). I know FreeSWITCH is not a drop-in replacement for the Asterisk PBX, but I don't want to change the behaviour of the PBX for the users. It's a preconception in Germany that the American people like (especially for the X-mas time) kitsch. Everyone here know the American houses with a hole bunch of blinking lights. But those decorated hoses are nothing against our offices! Our phones have up to 136 lights (BLFs). You often have to wear sunglasses at the office ;-) A typical usage of BLFs is to check if an agent is a member of the queue. I've build a simple extension to add and delete a member. I can user "presence in" and "presence out" to enable or disable the BLF, but there is one big issue. After a reboot of the phone the the user is still a member of the queue, but the BLF is off. We are using hints at Asterisk to show the user if he is a member and it works even after a reboot - with "presence" at FreeSWITCH it works (of cause) not. Does anyone have an idea how to implement it? My current extension is just for testing and so I use mod_fifo. It shouldn't be a problem to use mod_callcenter. The phone calls "queue-the_name_of_the_queue-the_name_of_the_user@pbxdomain" eg. "queue-sales_de-1000(a)freeswitch.cust" So how implement BLF persistence?

Mod_callcenter reload xml error
by asilva＠wirelessmundi.com 16 Feb '11

16 Feb '11

Hi, Is it possible to reload mod_callcenter to force it to reload / reset the configuration form the XML and synchronized it to callcenter database. I'm using the latest git and i couldn't find any option that allows me to do that... My idea is to add / or remove queues or even change some parameters, or add more agents to the xml and with a single command reload the new configuration. I notice that i have callcenter_config queue load | unload callcenter_config agent add | del is very painful to add or remove one element by one when i remove it form the xml. I tried to reload the mod_callcenter: # reload mod_callcenter R: +OK module unloaded +OK Reloading XML +OK module loaded [...] 2011-02-16 01:34:38.155841 [DEBUG] mod_callcenter.c:1045 Updated Agent cc1_queue1_agent1 set contact = [call_timeout=30]loopback/101/local 2011-02-16 01:34:38.156843 [DEBUG] mod_callcenter.c:1045 Updated Agent cc1_queue1_agent1 set status = Available 2011-02-16 01:34:38.157845 [DEBUG] mod_callcenter.c:1045 Updated Agent cc1_queue1_agent1 set wrap_up_time = 40 2011-02-16 01:34:38.159849 [DEBUG] mod_callcenter.c:1045 Updated Agent cc1_queue1_agent1 set type = callback 2011-02-16 01:34:38.161865 [DEBUG] mod_callcenter.c:1166 Updated tier: Agent cc1_queue1_agent1 in Queue cc1_queue1 set level = 1 2011-02-16 01:34:38.163868 [DEBUG] mod_callcenter.c:1166 Updated tier: Agent cc1_queue1_agent1 in Queue cc1_queue1 set position = 5 Seams to work, in the messages i see only the agents that are defined in the XML, but when i do: # callcenter_config agent list (i still have the previous agents that where defined) freeswitch@internal> callcenter_config agent list name|system|uuid|type|contact|status|state|max_no_answer|wrap_up_time|reject_delay_time|busy_delay_time|last_bridge_start|last_bridge_end|last_offered_call|last_status_change|no_answer_count|calls_answered|talk_time|ready_time cc1_queue1_agent1|single_box||callback|[call_timeout=30]loopback/101/local|Available|Waiting|0|40|0|0|0|0|0|1297815798|0|0|0|0 cc1_queue1_agent2|single_box||callback|[call_timeout=30]loopback/105/local|Available|Waiting|0|40|0|0|0|0|0|1297815798|0|0|0|0 +OK Is it a bug in the CLI?
