How to detect if the call is being transferred?
by Anis Bedhiafi 10 Oct '16

10 Oct '16

Hello I am working on application using Freeswitch and SIP.js in which I need to detect if the call is being transferred. The Sip.js application is actually an outbound dialer in which I load a list of phone numbers to call. The application starts by calling people. It is interesting to detect voicemail boxes. For that I am using mod_avmd. My problem is when the other end transfers the call, the sip.js client should know that the current call is being transferred. Is there a way that the original caller (sip.js client) knows that the call is being transferred? I was looking at all the channel variables and I found that the RDNIS variable and the transfer_time variable are filled up when there is a transfer. Is there a way to listen to the channel variables during the call and detect any change? Or is there a better way I can do it? Thank you for any suggestion. Anis Bedhiafi

mod_python and new Session from freeswitch.Session
by Андрей Асташов 10 Oct '16

10 Oct '16

Hi Guys. >From Dialplan run scripts in Python, from which I perform freeswitch.session("......"). That is, create a new session. And if I do not get an answer for a long time from the gateway, the execution of other scripts in Python is delayed until such time as the session will not be installed. Please tell me how you can create a new session, and do not block completely mod_python. I understand that once had to be done through ESL, but now everything has already been written by the script from the dialplan. And it works, if it does not create a new session. freeswitch@Test-Environment> # # Execute python script from fs_cli(in dialer mode): # fs_cli --retry --batchmode --interrupt --execute="python python_test_script" # 2016-10-07 17:55:29.970991 [NOTICE] mod_python.c:212 Invoking py module: python_test_script 2016-10-07 17:55:30.119989 [NOTICE] switch_cpp.cpp:1360 -->(489d5441-701d-4a98-80ca-3389b00fa98a) Create a new session through freeswitch.Session("sofia/gateway/Goip_One/+71234567890@192.168.100.28:5060 ") 2016-10-07 17:55:30.119989 [NOTICE] switch_channel.c:1104 New Channel sofia/external-g-eth0.nostun.noauth/%2B71234567890@192.168.100.28:5060 [489d5441-701d-4a98-80ca-3389b00fa98a] freeswitch@Test-Environment> # # New incoming call # 2016-10-07 17:55:33.920114 [NOTICE] switch_channel.c:1104 New Channel sofia/external-g-eth0.stun.auth/384851(a)1.2.3.4 [e11d39b8-0479-4d4b-bd8b-28634f0a970a] 2016-10-07 17:55:33.920114 [INFO] mod_dialplan_xml.c:637 Processing 384851 <384851>->318386 in context hive-context # # Execute second python script from dialplan: # 2016-10-07 17:55:33.920114 [NOTICE] mod_python.c:212 Invoking py module: python_test_script freeswitch@Test-Environment> # # 12 seconds of silence during which any python script will not be executed and will be expected to complete # freeswitch@Test-Environment> 2016-10-07 17:55:45.140231 [NOTICE] sofia.c:8078 Hangup sofia/external-g-eth0.nostun.noauth/%2B71234567890@192.168.100.28:5060 [CS_CONSUME_MEDIA] [UNALLOCATED_NUMBER] 2016-10-07 17:55:45.160086 [NOTICE] switch_cpp.cpp:1360 -->(489d5441-701d-4a98-80ca-3389b00fa98a) After Create a new session through freeswitch.Session 2016-10-07 17:55:45.160086 [NOTICE] switch_core_session.c:1665 Session 15 (sofia/external-g-eth0.nostun.noauth/%2B71234567890@192.168.100.28:5060) Ended 2016-10-07 17:55:45.160086 [NOTICE] switch_core_session.c:1669 Close Channel sofia/external-g-eth0.nostun.noauth/% 2B71234567890@192.168.100.28:5060 [CS_DESTROY] # # Continue executing second python script(from 2016-10-07 17:55:33.920114) after any answer from first python new freeswitch.Session # 2016-10-07 17:55:45.160086 [ALERT] switch_cpp.cpp:1360 (mtid:3656): Traceback 280920161717(e11d39b8-0479-4d4b-bd8b-28634f0a970a): --> 12 <--; now: 1475841345; python_start_time:1475841333;

Using presence or state to avoid intercom barge-in
by Phil Quesinberry 09 Oct '16

09 Oct '16

Hi, We're running into an issue with Cisco SPA50x phones where an intercom call to an extension either places the currently active call on hold or hangs up on it and switches to the intercom call. We'd like to not have this happen if the destination extension is in use. The only way I know of to do this would involve reconfiguring all of the phones to share presence and then check it in the dialplan before bridging. Is there a convenient "no-barge" variable or similar that can be set so FS won't send the invite if the extension is in use or a way to check the extension's state from the dialplan? I'm guessing that's a NO but I had to ask! Alternatively, is there a way to get the Cisco phones not to interrupt the call in progress when a call comes in? Instead of setting sip_auto_answer=true, I've also tried setting sip_h_Call-Info=<sip:ip.address.of.server>;answer-after=0 which appears to stop this behavior on the Aastra phones but not the Cisco phones, although I'm not entirely sure about this as I now can't seem to reproduce the undesired behavior on the Aastra phones... Dialplan entry for the intercom as it stands is as follows: <extension name="extension-intercom-fix" continue="true"> <condition field="destination_number" expression="^\*8(\d{2,7})$" > <action application="set" data="dialed_extension=$1" /> <action application="bridge" data="user/${dialed_extension}@${domain_name}" /> <action application="export" data="sip_auto_answer=true" /> </condition> </extension> Any thoughts or advice would be appreciated.

I would like to configure a user that would be allow to use only one codec and call only from a certain subnet like 192.168.5.x. Is that possible? Thank you Valter

SIP Proxy
by Valter Nogueira 07 Oct '16

07 Oct '16

In Asterisk, I have a "SIP Proxy", with 2 sip trunk. An external Asterisk dials in SIP-1 and asterisk, thru the dialplan, sends the call to SIP-2 (an ISTP) In Freeswitch, I don't know if I should use directory/user for "SIP-1" or if it is allowed to use a gateway inside internal sip_profile. Is it possible authenticate user by IP instead of user/password? Thanks, Valter

ESL terminate calls
by Gonzalo Gasca Meza 07 Oct '16

07 Oct '16

I'm launching API Calls using ESL in FS 1.6 (via python) For each new call, after call is hangup, I send a *uuid_kill* and then ESL.client.disconnect() Are both necessary, or I can skip *uuid_kill*? I'm trying to improve performance in my ESL and avoid unnecessary TCP connections to Freeswitch. Thanks -G

Asynchronous PTIME not supported
by Voxbox.io 07 Oct '16

07 Oct '16

Hi Guys, I'm getting an high CPU usage when managing calls. Looking at console I can see too many messages like this: [WARNING] switch_core_media.c:2042 Asynchronous PTIME not supported, changing our end from 20 to 10 Do you know what they means? It's a problem relating to reframing of packets? If so, can I reject calls with a different frame than I specify? Thanks Max

Kernel Hyperthreading ON or OFF?
by Raimund Sacherer 06 Oct '16

06 Oct '16

Hi, we have a new Freeswitch cluster with Dell R410. It has 2 CPUs (Xeon E5620, QuadCore. it's 8 cores withouth HT and 16 cores with HT. I googled with hyperthreading and freeswitch but some say turn it on it will give you a boost, others say turn it off, you will gain performance. Does anyone know if it's better to leave it on or turn it off? And some small explanation? I would be very gratefull for your help, best regards Raimund --
