How to call multi gateways for failover with early media?
by dujinfang 06 Apr '09

06 Apr '09

Hi, I have outbound gateways returns 403 or 503 constantly. So I tried to dial out using sofia/gateways/gw1/xxxx|sofia/gateways/gw2/xxxx|sofia/gateways/gw3... for fail over. To make it work, I need to set ignore_early_media=true. However, the caller do need to hear the early media to figure out what's going on. If I set ignore_early_media=false, only the first one tried. A little more detail: The gateway is first tier, if it cannot initiate a PSTN channel returns 403/503 immediately. If it can find a PSTN channel, but the callee fails, no answer or busy or others, it plays early media and returns 503. If I want failover, and the early media, how to do that? Thanks. regards, Seven.

Freeswitch not started OK at boottime?
by Fred 06 Apr '09

06 Apr '09

Hello I'm having a problem connecting to the Freeswitch server running on a Suse server when the it's started at bootime, but OK if I start it manually through the init.d script, so I guess I did something wrong when setting things up. Here's what I did: 1. Downloaded and compiled the latest SVN source 2. cp /usr/src/freeswitch/build/freeswitch.init.suse /etc/init.d/freeswitch 3. chmod 755 /etc/init.d/freeswitch 4. chkconfig freeswitch 345 5. chkconfig -l freeswitch 6. (why needed in addition to chkconfig?) ln -s /etc/init.d/freeswitch /usr/sbin/rcfreeswitch 7. Edit /etc/init.d/freeswitch: FREESWITCH_BIN=/usr/local/freeswitch/bin/freeswitch #(BAD!) FREESWITCH_CONFIG=/usr/local/freeswitch/conf/freeswitch.xml FREESWITCH_PARAMS="-nc" Here's what it says when I try to connect to the server: ========= # ps aux | grep free root 3497 0.6 0.7 16912 8212 ? Sl 12:03 0:00 /usr/local/freeswitch/bin/freeswitch -nc # cd /usr/local/freeswitch/bin/ # ./fs_cli [ERROR] libs/esl/fs_cli.c:642 main() Error Connecting [Socket Connection Error] ========= Here's how to solve this issue manually: ========= # /etc/init.d/freeswitch stop Shutting down FreeSWITCH done # /etc/init.d/freeswitch start Starting FreeSWITCH 3867 Backgrounding. done /usr/local/freeswitch/bin # ./fs_cli [logo deleted] +OK log level [7] freeswitch@internal> /exit # ========= Any idea what is wrong? Thank you for any hint.

High CPU load but only few sessions
by Helmut Kuper 06 Apr '09

06 Apr '09

Hello, since a few days I observe a high CPU load of my FS server, but I have no idea what it could be. There are only a few sessions running and there is only a few log activity. 2 days ago I restarted FS, but no change. The top command shows this: top - 15:02:33 up 106 days, 30 min, 4 users, load average: 0.24, 0.35, 0.42 Tasks: 190 total, 1 running, 189 sleeping, 0 stopped, 0 zombie Cpu(s): 7.2%us, 12.2%sy, 0.0%ni, 80.0%id, 0.2%wa, 0.2%hi, 0.2%si, 0.0%st Mem: 4151776k total, 4003664k used, 148112k free, 414708k buffers Swap: 15623204k total, 88k used, 15623116k free, 2021412k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 14048 ippbx 20 0 1555m 1.2g 10m S 43 30.5 333:11.03 freeswitch 14049 ippbx 20 0 1555m 1.2g 10m S 0 30.5 5:06.88 freeswitch 14054 ippbx 20 0 1555m 1.2g 10m S 0 30.5 4:14.38 freeswitch 14055 ippbx 20 0 1555m 1.2g 10m S 0 30.5 4:58.50 freeswitch 14057 ippbx 20 0 1555m 1.2g 10m S 0 30.5 13:05.20 freeswitch 20511 ippbx 20 0 1555m 1.2g 10m S 0 30.5 0:00.14 freeswitch so only one process (PID: 14048) is causing that load.

Can I shot it down via kill or "kill -9" without crashing FS totally? regards helmut

FS failover redundancy & load balancing
by Ashley van Gerven 04 Apr '09

04 Apr '09

Hi, I can't find much info on setting up a redundant or heavy load FreeSwitch implementation. Are there any links apart from: http://wiki.freeswitch.org/wiki/Enterprise_deployment ? I imagine the entry level solution is to have two FS boxes configured identitcally, with redundant SBC software (recommendations?) in front, passing the calls to the primary FS box, or the backup FS box if the primary is not responding. Is that the easiest solution? What about a situation of having a level of concurrent calls beyond what one FS box can handle? I realise that would be a very large number of concurrent calls, but we would need a good plan on how to scale the systems. Are there recommendations for load balancing solutions? Either soft or hardware? My guess would be having 3 + 1 spare FS servers would work, where calls are distributed accross 3 FS boxes by a load balancer with one spare in event of failure. Also how would a FS box at max capacity behave? Does FS monitor available resources and reject the excess calls that it can't handle? Or would the load balancer have to be configured with the maximum number of calls per box? Would love to hear some experiences of deploying FS with failover & high load. Thanks Ash

codecs initialization flags in endpoint modules
by Lele Forzani 03 Apr '09

03 Apr '09

Hello, I've been experimenting with the use of mod_dahdi_codec and other ways to perform external transcoding for codecs, and came up with noticing that transcoding resources seemed to be used up twice what I expected. That is and 2x the number of call legs, ending up to two encoder and two decoder instances per leg. So, I looked at the code and noticed almost every endpoint module does something like this (excerpt from mod_sofia, sofia_glue.c:~1800): if (switch_core_codec_init(&tech_pvt->read_codec, tech_pvt->iananame, tech_pvt->rm_fmtp, tech_pvt->rm_rate, tech_pvt->codec_ms, 1, SWITCH_CODEC_FLAG_ENCODE | SWITCH_CODEC_FLAG_DECODE | tech_pvt->profile->codec_flags, NULL, switch_core_session_get_pool(tech_pvt->session)) != SWITCH_STATUS_SUCCESS) { switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_ERROR, "Can't load codec?\n"); switch_goto_status(SWITCH_STATUS_FALSE, end); } if (switch_core_codec_init(&tech_pvt->write_codec, tech_pvt->iananame, tech_pvt->rm_fmtp, tech_pvt->rm_rate, tech_pvt->codec_ms, 1, SWITCH_CODEC_FLAG_ENCODE | SWITCH_CODEC_FLAG_DECODE | tech_pvt->profile->codec_flags, NULL, switch_core_session_get_pool(tech_pvt->session)) != SWITCH_STATUS_SUCCESS) { switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_ERROR, "Can't load codec?\n"); switch_goto_status(SWITCH_STATUS_FALSE, end); } The flags being SWITCH_CODEC_FLAG_ENCODE | SWITCH_CODEC_FLAG_DECODE seems to be causing the apparent 'double' allocation of transcoding resources, and I fail to understand the need for both, in both cases. Could someone please spend a minute to explain? thanks lele

Re: [Freeswitch-users] mod_shout delay in trunk
by freeswitch-users＠digitaldan.com 03 Apr '09

03 Apr '09

I have my burst rate set to something low, 4096 right now. I also wrote a flash/flex app that has the same size buffer which results in the audio being heard immediately when connecting. As far as the audio being real time, the audio stream is about 6 seconds behind which I'm guessing is the result of the size of the lame buffers in the mod_shout modules (i'm using g.711 ulaw), I was going to look into that next week. Anyone have any thoughts about where else the delay may be happening? I hoping to get this down to around 2 seconds.

Ah, that is easy enough! Though I think with icecast doing the burst_on_connect thingie there should be enough data (pushed much faster than real time) to fill FS's buffers. But that would require mod_shout to cooperate with that strategy. ie: on connect, drain the socket as fast as it can filling it's own buffers. Once it's own buffers are full start streaming. I think right now it drains the socket only as fast as it needs to. Or maybe not. <shrug/> I'll go the local stream route for now.... -- -Rupa _______________________________________________ Freeswitch-users mailing list Freeswitch-users(a)lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org

Slow freeswitch shutdown

In last SVN trunk version i noticed that stopping of freeswitch takes much time. I have configuration installed with freeswitch. I added sip gateway to my asterisk instance.

Use rates from lcr in nibblebill module
by Yuriy Ivzhenko (WP) 03 Apr '09

03 Apr '09

Hi, I want to use module lcr to find a best route and his rate , then make a call and bill on that rate with nibblebill module. lcr return variable "lcr_auto_route" that contains "[lcr_rate=xxx]" variable for new channel. To use nibblebill i need to set "nibble_rate" = "lcr_rate". What is best method to do that? Is there a way to do that with standard tools, without use external scripts? Thanks, Yuriy
