Re: [Freeswitch-dev] MTU setting and application buffer size
by Juraj Fabo 17 Oct '11

Hi, I read through the previous answers several times again and did some progress. I found out that the valid codec_ms values are <10ms,60ms> and using lower values will not work. >> 80 means a hardware interrupt is received every 10ms with 80 bytes per >> time slot. This is the recommended mode. A value of 40 will increase >> interrupt load and not necesarily reduce your latency, you must reduce >> the "user period", which is how often the driver will deliver >> media/data to the user application. This is done using >> sangoma_tdm_set_usr_period(). >> >> >> The codec_ms is used to call sangoma_tdm_set_usr_period(). This is how >> often the driver will deliver data to the user application (for >> example, waking it up from select()). >> In each of the the test below the codec_ms was set to 1 with hope of fastest data delivery, however this resulted to 20ms codec_ms which is default. > Please, have a look at the results with various parameters used: > mtu:80 txqueue_size=1 rxqueue_size=1 one-direction delay=60ms > round-trip delay=120ms > mtu:80 txqueue_size=2 rxqueue_size=2 one-direction delay=80ms > round-trip delay=160ms > mtu:80 txqueue_size=10 rxqueue_size=10 one-direction delay=240ms > round-trip delay=480ms > mtu:40 txqueue_size=1 rxqueue_size=1 one-direction delay=40ms > round-trip delay=80ms > mtu:40 txqueue_size=2 rxqueue_size=2 one-direction delay=60ms > round-trip delay=120ms > mtu:40 txqueue_size=5 rxqueue_size=5 one-direction delay=120ms > round-trip delay=240ms > mtu:16 txqueue_size=1 rxqueue_size=1 one-direction delay=30ms > round-trip delay=60ms > mtu:8 txqueue_size=1 rxqueue_size=1 one-direction delay=25ms > round-trip delay=50ms > mtu:8 txqueue_size=10 rxqueue_size=10 one-direction delay=205ms > round-trip delay=410ms > Updated test result with the codec_ms=10 is following: mtu:16 txqueue_size=1 rxqueue_size=10 one-direction delay=20ms round-trip delay=50ms mtu:80 txqueue_size=1 rxqueue_size=10 one-direction delay=56ms round-trip delay=110ms However, this is still not 10ms with the default MTU:80 and codec_ms:10 :( Anyway, is it a good idea to use so assymetric tx/rx queue sizes? with best regards Juraj

Hi, I am having a problem connecting to LDAP database from dialplan using lua script. When I run the below script from xml dialplan it causing a coredump and Freeswitch crashes.

questions on the new mod_sms
by Seven Du 07 Oct '11

07 Oct '11

Fatastic! I cannot help to try the new mod_sms, and here's some quick questions for developers and I'm seeing what can I help with testing/coding etc. to speed this up. 1) I see no event when I use the chat app "fire" with /event all in fs_cli, is there a problem or unfinished code? 2) Also I see nothing when I use the "send" app, I guess a catch all chatplan with <action application="send" data=""/> would have the same effect as before(when no mod_sms). I tried with a. unload mod_sms, two US send text messages to each other without problem b. load mod_sms, I see this log but nothing happened 2011-09-24 10:03:48.921888 [INFO] mod_sms.c:299 Processing text message 1004->1001 in context default Chatplan: 1001 parsing [default->demo] continue=false Chatplan: 1001(a)192.168.7.2 Regex (PASS) [demo] to(1001(a)192.168.7.2) =~ /^(.*)$/ break=on-false Chatplan: 1001(a)192.168.7.2 Action send() 2) How to get variables in lua? will there be an event object like session in dialplan based ? 3) also I see the chat api also hit the chatplan, is that supposed to? Sorry for so many questions, thanks. -- About: http://about.me/dujinfang Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn Sent with Sparrow (http://www.sparrowmailapp.com)

by succer110＠tiscali.it 07 Oct '11

07 Oct '11

Hi, I'm writing some part of dialplan in lua and after bridge a have to execute an application. I receive this: "Channel is hungup, aborting execution of application: antani-postdial". Of course i've tried all the kind of app interface flags.my dialstring contains right variable:2011-10-07 13:07:51.817103 [DEBUG] switch_event.c:1168 Parsing variable [continue_on_fail]=[true]2011-10-07 13:07:51.817103 [DEBUG] switch_event.c:1168 Parsing variable [hangup_after_bridge]=[false] p.s. in the docs i can find "SAF_ZOMBIE_EXEC" but it's not in my switch_types.h what can i do to exec my postdial application in my lua? dialstring="{ignore_early_media=true,originate_timeout=90,continue_on_fail=true,hangup_after_bridge=false}"..dialstringlocal sessionB = freeswitch.Session(dialstring);freeswitch.bridge(session, sessionB)session:execute("antani-postdial", i); Thank you! =) E' nata indoona: chiama, videochiama e messaggia Gratis.

MOH in async mode is possible?
by Vu Quang Hoa 07 Oct '11

07 Oct '11

Hi everyone, I've been trying ways to provide MOH in background of Lua script (searching and found few way) but none of them really satisfied me. I think it may implement in the same way of record_session function. So I need your advises if it is possible or not? It's a really good idea? Thank you! vutamhoan

by succer110＠tiscali.it 03 Oct '11

03 Oct '11

Hi! I'm a new fs module developer :) In the page "authoring freeswitch module" i read that "there's still times when using traditional C memory management is a better plan." How can i recognize that cases? >From what i have understood using memory pool from apr i can forget to call switch_core_destroy_memory_pool unless i specifically want it. Am i Right? Is possibile to specify the dimension of the memory pool i want to create? Which is the standard dimension? Thankyou =) E' nata indoona: chiama, videochiama e messaggia Gratis.
