Can't Send emails from within FreeSwitch
by Dmitry Saratsky 26 Feb '11

26 Feb '11

Hi All, Unfortunately I can't send email from within freeswitch. I have wrote some LUA script that should send emails. The relevant part of the script: ----------------- freeswitch.email("user(a)domain.com", "user(a)domain.com", "subject: Test subject.\n", "Test body.") ----------------- When script runs, it logs the following to console: ----------------- 2011-02-26 23:44:23.624644 [DEBUG] switch_utils.c:709 Emailed data to [ user(a)domain.com] ----------------- In my switch.conf.xml I have the following mailer-app config: ----------------- <param name="mailer-app" value="sendmail"/> <param name="mailer-app-args" value="-t"/> ----------------- I also have tried to use full path to sendmail app: ----------------- <param name="mailer-app" value="/usr/sbin/sendmail"/> ----------------- I'm using: CentOS release 5.5 (Final) FreeSWITCH Version 1.0.head (git-cb6f1ed 2011-02-22 20-25-16 -0500) postfix-2.3.3-2.1.el5_2 (as MTA) The problem is, that no mail is received and nothing logged in /var/log/maillog. However I can successfully send emails from shell (from within freeswitch's user) with sendmail -t command. I have also wrote simple bash script that add some text to /tmp/12.txt on run and pointed mailer-app (in switch.conf.xml) to this script full patch file - nothing was added to the file. Any Ideas? Thanks, Dmitry.

Anyone know a provider for LRN lookups for ported numbers in NANPA? Preferably someone who can provide the whole database, or flat rates for a month of lookups. Essobi

Bridge app and SIP 503
by Bill W. 26 Feb '11

26 Feb '11

Hi all, I'm using a failover bridge string with several gateways. <action application="bridge" data="sofia/gateway/primary/dialstring|sofia/gateway/secondary/dialstring"/> One of the gateways responded to a mis-dialed number with a "503 Service Unavailable" instead of a "484 Address Incomplete" My FreeSWITCH servers are behind a load-balancer, and what is happening is the bridge app is passing that 503 back to the load-balancer which then marks that gateway as down. I can't remove the 503 detection from the load balancer, because that's how I disable a gateway from within freeswitch (fsctl pause, which sends 503). Does anyone have any recommendations on how to address this issue? Thanks!

send fax in one leg call
by Madovsky 26 Feb '11

26 Feb '11

I'm trying to send a fax to a one leg call. for example a registered user wants to send a fax to another registered user so I have this in my default dialplan <extension name="internal_fax"> <condition field="${sip_to_uri}" expression="^(\+)(\d{10})@$${domain}$"> <action application="ring_ready"/> <action application="set" data="execute_on_media=tone_detect fax 1100 r +5000 transfer 'receivefax XML features' 2" /> <action application="sleep" data="2000"/> <action application="answer"/> <action application="voicemail" data="default ${domain_name} ${sip_to_user}"/> </condition> </extension> for now I have no other way to send the fax from CLI like this: fs_cli -x "uuid_broadcast <uuid> execute_extension::' sendfax XML features' <aleg=timeout??> <bleg=no bleg??>" thanks Franck

ESL socket outbound: clean way to close a session?
by Stephen Wilde 25 Feb '11

25 Feb '11

I have problem to clean close an outbound session. I'm using the "esl_oop.h/esl_oop.cpp" files and my application is developed in c++ and at startup I do a "linger" command. My event consuming loop is: while (run) { ESLevent * event = connection.recvEventTimed(sleeptime); ... event processing ... } This application handle an inbound call (legA), originate an outbound call (legB) and bridge the two calls. The problem is present when the legA hangup the call: sometimes is received the content-type="text/disconnect-notice" (without receiving "CHANNEL_HANGUP") and the "recvEventTimed" exits with event=NULL. In this case it's not possible to receive any event or send any other message to Freeswitch because the "connection.execute" fails. In this situation, if I have originated (with '& park') an outbound call, this call remain in parked state and the application cannot hangup it. What I'm doing wrong?

audio<->T38 gateway problem
by Wesley Akio 25 Feb '11

25 Feb '11

Hi All, I have a FreeSwitch box running FreeSWITCH version: 1.0.head (git-c6e7988 2010-12-09 14-25-39 -0600) under CentOS 5.5. I need freeswitch act as a gateway with G711 in one side an T38 in the other: Caller:G711--->FreeSwitch--->Callee:T38 I tried several variations of dialplans without success and was hoping someone could help me, the call stablishes in G711 and I could not find a way to switch to t38. My current dialplan follows: <condition field="destination_number" expression=".*" break="on-true"> <action application="set" data="fax_enable_t38=true"/> <action application="set" data="execute_on_answer=t38_gateway peer"/> <action application="set" data="hangup_after_bridge=true"/> <action application="set" data="progress_timeout=10"/> <action application="set" data="effective_caller_id_name=0000"/> <action application="set" data="effective_caller_id_number=0000"/> <action application="set" data="execute_on_answer=sched_hangup +9000 alloted_timeout"/> <action application="bridge" data="sofia/testfax/1234(a)1.2.3.4"/> </condition> Thank you, Wesley Akio

PlayAndGetDigits parameters
by Malay Thakershi 25 Feb '11

25 Feb '11

Recently I upgraded to latest GIT version and found there was an extra parameter to this function. I have two questions if someone can explain: --> 4th parameter * timeout = Number of milliseconds to wait once the file is done playing before you type a digit. >From the name, I alway thought this had to do with user's inactivity at the prompt. So if value is 3000, after 3 seconds of inactivity prompt will either do a retry or move on. But I think from wiki description, it seems # of milliseconds for which data entry will be blocked, am I correct? --> 10th parameter * digit_timeout = Number of milliseconds to wait after DTMF ( Added Here[1]<http://fisheye.freeswitch.org/changelog/freeswitch.git/?cs=cfa30468e89788d2…> ) What does this do? Is it # ms to wait before second digit can be pressed? I have following function in mod_managed code. pStrLivePreObInput = mObjMainSession.PlayAndGetDigits(5, 5, 3, 5000, "", pStrObGreetTextFile.Replace(".txt", ".wav"), @"C:\FreeSWITCH\sounds\en\us\chAsmt\static\error\invalid_number.wav", "^\\d", "", 3000); Does that mean user has to wait 5 seconds before a key entry can be accepted? And there has to be 3 seconds gap between each key? If so, I will need to redo the timing. Please let me know. Malay

Second transfer
by Santiago Soares 25 Feb '11

25 Feb '11

Hello, I'm using att_xfer to make call transfer, like that: A calls B B calls C B hangup and A is bridged do C The thing is, the way I am trying to do it, C is able to transfer the call again. I don't want that C be able to transfer the call again. The call should be transfered only once. Is it possible? This is my dialplan: <include> <extension name="test_extension"> <condition field="destination_number" expression="^numberB$"> <action application="set" data="bind_meta_key=*"/> <action application="bind_meta_app" data="3 b s execute_extension::transferencia XML public"/> <action application="bridge" data="sofia/gateway/test/loginB"/> </condition> </extension> <extension name="transferencia"> <condition field="destination_number" expression="^transferencia$"> <action application="read" data="3 3 base256/16000/sound.wav attxfer_callthis 30000 #"/> <action application="execute_extension" data="transferencia2"/> </condition> </extension> <extension name="transferencia2"> <condition field="${attxfer_callthis}" expression="^numberC$"> <action application="att_xfer" data="sofia/gateway/test/loginC"/> </condition> <condition field="${attxfer_callthis}" expression="^numberD$"> <action application="att_xfer" data="sofia/gateway/test/loginD"/> </condition> </extension> </include> Thank you, Santiago Soares
