Defunct process in ESL testserver example
by MohammedShehzad 13 Jan '10

13 Jan '10

Hello everybody, I am creating a C program of ESL outbound for call processing. I am using testserver.c example, and till now it seems fine. But i noticed that every call testserver process, a new process is being created which I can see in Linux system with below command: For example, when I make two calls and even after hangup, I saw three process like below: ps -A | grep testserver 9345 pts/2 00:00:00 testserver 9350 pts/2 00:00:00 testserver 9357 pts/2 00:00:00 testserver This get increased for every call i make. I did some workout and placed below two lines (close & exit) at the end of mycallback function, (as I found them on ivrd.c file): esl_disconnect(&handle); close(client_sock); exit(0); } But after that the process becomes defunct/zombie 9440 pts/2 00:00:00 conflisten 9442 pts/2 00:00:00 conflisten <defunct> 9452 pts/2 00:00:00 conflisten <defunct> Will anybody please suggest me how can I eliminate this process, which remains in memory even after call hangup? Thanks for any response. MohammedShehzad

ShoreTel to FS connection
by John 13 Jan '10

13 Jan '10

I am trying to utilize a freeswitch system as a SIP trunk for ShoreTel. I have had to change the port from 5080 to 5060. When I dial through, I see on the FS console show the call; however I can't seem to change the public.xml dialplan to effect any changes in the behaviour. How can I tell which dialplan the external call is using? 2010-01-12 13:04:17.705548 [NOTICE] switch_channel.c:613 New Channel sofia/external/+19705551212@192.168.155.13:5060 [aa2f2fde-ffb5-11de-9590-015cd8b8c273] 2010-01-12 13:04:17.705548 [INFO] mod_dialplan_xml.c:408 Processing Extension 1002->5551212 in context public 2010-01-12 13:04:17.705548 [NOTICE] switch_core_state_machine.c:187 Hangup sofia/external/+19705551212@192.168.155.13:5060 [CS_EXECUTE] [NORMAL_CLEARING Thanks John

Channel Variables with spaces
by Brian Engert 13 Jan '10

13 Jan '10

I'm trying to set a channel variable with a space in it when I run the originate command. The command only seems to work when I escape the space with a \ however that backspace get's passed on. Some examples are originate {fax_ident=1231231234,fax_header=testing\ spaces}sofia/gateway/outbound.fax/1004 &txfax(/tmp/fax.tiff) originate {fax_ident=1231231234,fax_header=testing spaces}sofia/gateway/outbound.fax/1004 &txfax(/tmp/fax.tiff) The first one will go through just fine but the fax at the other end gets "testing\ spaces" the second one gives me "2010-01-12 16:35:18.41325 [ERR] switch_ivr_originate.c:990 Parse Error!" I think this could also be done as a profile but I would rather do it from the call. I've looked around the wiki and have not seen any examples that use a space when doing the originate call. - Brian

PRI Goes Down Upon Calling Cell Phone
by Jerry Richards 12 Jan '10

12 Jan '10

I am having a problem where my PRI goes down after attempting to call a cell phone from an internal phone. I am running Freeswitch (freeswitch-1.0.5-20100112-0400.tar.gz) with an A101D Sangoma Card and wanpipe driver: wanpipe-3.5.10.tgz. I am not using libpri. The scenario is as follows: 1) Call desktop phone 3491006 2) Call completes normally 3) Call cell phone 4181432 (see http://pastebin.freeswitch.org/11767) ***** call fails; cell phone rings, but does not complete ***** 4) Call desktop phone 3491006 ***** call fails; far-end does not ring ***** 5) Any subsequent calls through PRI fail I notice the call to my cell phone receives a Q.931 PROGRESS message instead of Q.931 ALERTING. Has this issue already been identified as a bug? Do you know if this is a FS issue? Or Wanpipe driver issue? Best Regards, Jerry

Cisco SPA5xx SCA
by Peder 12 Jan '10

12 Jan '10

Anybody know the settings on the SPA5xx to make SCA work? I've tried all sorts of combinations of shared/private on the ext and phone and set the Server type to Broadsoft, etc and it just never seems to work. Do I need the BLF info? Do I set shared/private on the phone, or ext, or both? Do I need to enable SCA Line ID Mapping? Or SCA Barge-In Enable? Or both? Peder

How to provide dynamic directory information?
by Mike van Lammeren 12 Jan '10

12 Jan '10

Hello! I'd like to be able to have FreeSWITCH check a database for authorization, every time a user registers. There are some great examples on the wiki, which use either MOD_XML_CURL or Lua to dynamically provide a dialplan, but I cannot find an example for providing a directory. I am developing an application that will have thousands of users, and will run on multiple FreeSWITCH servers behind a load balancer. Ideally, FreeSWITCH would only look-up directory information, specifically, username and password, whenever a user attempts to connect. The directory information will be changing regularly, as users are added or removed from the system. Is this possible with FreeSWITCH? Or can only dialplan information be provided dynamically? I've written a script in Lua that provides the XML data, such as that found in the example /freeswitch/conf/directory/default/ folders, and I try to call it with this bit of XML in /freeswitch/conf/directory/default.xml: <groups> <group name="default"> <users> <param name="xml-handler-script" value="/directory.lua"/> <param name="xml-handler-bindings" value="users"/> </users> </groups> Is this the right approach? Am I going about this the right way? I would appreciate any tips that anyone can provide! Thanks! Mike van Lammeren

Fax Codecs
by Joseph L. Casale 12 Jan '10

12 Jan '10

While faxing is working, I am seeing these in the log when I attempt to use rxfax: switch_ivr_play_say.c:1154 Codec Activated L16@8000hz 1 channels 30ms switch_core_io.c:652 sofia/internal/1002(a)192.168.13.1 receive message [TRANSCODING_NECESSARY] So later I see: switch_core_codec.c:128 sofia/internal/1002(a)192.168.13.1 Restore previous codec PCMU:0 So I am actually not clear on what's happening? I thought I had the ua set to PCMU but I guess fs is seeing the incoming sip session as L16 which I read is bad for fax? What's the significance of the last line where it states its restoring the old codec? Can anyone shed some light on what's actually happening? Thanks! jlc

Multi-Homed setup, starting over - still not working
by mailinglist 12 Jan '10

12 Jan '10

Hi Guys I really would like to have this up and running, but I'm constantly running into things that doesn't work, and I have no idea where the problem is... I've started from scratch with pfSense and Freeswitch. I've followed the Multi Home tutorial here: http://wiki.freeswitch.org/wiki/Multi_home_tutorial I've deleted the 'lan' profile, and altered the 'internal' profile as recommended, and I've gotten to the paragraph: APPLYING YOUR CHANGES AND CHECKING YOUR WORK When I start up my x-lite program I get this error: 2010-01-12 16:38:54.172731 [WARNING] sofia_reg.c:1755 Can't find user [1000(a)83.89.x.x] You must define a domain called '83.89.x.xin your directory and add a user with the id="1000" attribute and you must configure your device to use the proper domain in it's authentication credentials. and you must configure your device to use the proper domain in it's authentication credentials. 83.89.x.x is my external IP, and not my internal IP??? Any help on this?

Gateway Configuration
by Joseph L. Casale 12 Jan '10

12 Jan '10

It seems there are two ways to configure an spa3102's fxo port w/ pbx's, you can set the dial plan to <phone_#_of_pstn>@<freeswitch_ip> or <ext_to_dial>@<freeswitch_ip>. >From fs's perspective, what exactly is the difference here? Are there any significant differences between the two methods? Are there any best practices that should be considered? Incoming sip did's and a zap line I had all were configured so that they entered the public context filtered by <phone_#>. Most of the examples I see for setting up the spa don't function like this but a couple do? Thanks! jlc
