How to kill call/channel on the reception of CUSTOM avmd::beep
by Aqs Younas 26 Feb '16

26 Feb '16

Hi, I have subscribed to CUSTOM avmd::beep and this is what I get. "Event-Subclass": "avmd::beep", "Event-Name": "CUSTOM", "Core-UUID": "11e64e66-f81b-4d23-a8e1-e6af0eaa0bbc", "FreeSWITCH-Hostname": "debian", "FreeSWITCH-Switchname": "debian", "FreeSWITCH-IPv4": "192.168.10.59", "FreeSWITCH-IPv6": "::1", "Event-Date-Local": "2016-02-25 10:46:17", "Event-Date-GMT": "Thu, 25 Feb 2016 15:46:17 GMT", "Event-Date-Timestamp": "1456415177487145", "Event-Calling-File": "mod_avmd.c", "Event-Calling-Function": "avmd_process", "Event-Calling-Line-Number": "550", "Event-Sequence": "3174", "Beep-Status": "stop", "Unique-ID": "80d33754-b234-47e2-b7c5-16ffa20f359c", "call-command": "avmd" Now I need to hangup that call(beep detected), but could not find any event variable connected to the call. How can i kill the call. Any pointer is much appreciated.

Transcoding and recording
by Oleg Stolyar 26 Feb '16

Hi guys, if I record a session where both A and B use the same codec, will transcoding occur? Basically, in this case will the same codecs gain any CPU advantage?

Call gets disconnected on write frame error
by Chris Young 26 Feb '16

26 Feb '16

Hi all, Recently, we've been experiencing a problem whereby FreeSWITCH disconnects a call after receiving a frame of audio data with a data length of 0. When this happens we see the following messages in the log: [DEBUG] switch_core_io.c:1503 Engaging Write Buffer at 320 bytes to accommodate 0->320 [ERR] switch_core_io.c:1518 Write Buffer 0 bytes Failed! and the call gets disconnected. This normally happens when trying to join a conference but we have also seen it when bridging two calls together. Is the call disconnection by-design or just a side-effect of having received the bad frame of data? Thanks, Chris

FreeSwitch second recovery
by Gorbachev Alexey 26 Feb '16

26 Feb '16

I installed FreeSwitch cluster according to official manual -https://wiki.freeswitch.org/wiki/Freeswitch_HA And it works, when I power off first node current calls successfully move to second node and voice disappears only for 3 second. The problem is when I power on first node, server starts FreeSwitch, and FreeSwitch during start up clears calls in database and of cause I can't move current calls back again to first node. Can I move current calls between servers without interruption again? Thank you.

gsmopen problem: INCOMPATIBLE_DESTINATION
by Nandy Dagondon 25 Feb '16

25 Feb '16

Hello guys, I installed mod_gsmopen. When testing incoming call, it hangs up with this error message INCOMPATIBLE_DESTINATION. I understand this is a codec negotiation issue. Looking at the CDR - the gsmopen presented L16 8000 in the SDP. By default, FS does early negotiation. Snippet of my internal sip_profile: <param name="inbound-codec-prefs" value="$${global_codec_prefs}"/> <param name="outbound-codec-prefs" value="$${global_codec_prefs}"/> <param name="rtp-timer-name" value="soft"/> <param name="rtp-ip" value="$${local_ip_v4}"/> <param name="sip-ip" value="$${local_ip_v4}"/> <param name="presence-privacy" value="$${presence_privacy}"/> <param name="inbound-codec-negotiation" value="generous"/> Take note: there is no disable-transcoding parameter which I understand FS is transcodind. In vars.xml: <X-PRE-PROCESS cmd="set" data="global_codec_prefs=G7221@32000h,G7221@16000h ,G722,PCMU,PCMA,GSM"/> <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=PCMU,PCMA,GSM"/> I tried to add L16 at the end of global_codec_prefs which is unnecessary, isn't it? But it didn't work, too. Finally, I added L16 in the softphone, it worked. I have installed gsmopen before and it worked (transcoding) with IP phones. Is there anything I may have missed? I appreciate for any leads. Thank you, /Nandy

Getting 503 when starting automatically via systemd
by freeswitch.opencode＠spamgourmet.com 25 Feb '16

25 Feb '16

I'm using Arch Linux (specifically Arch Linux ARM on a Raspberry Pi Zero). I'm successfully done a make and install for freeswitch 1.6.6 and when I run it manually (freeswitch -nonat), it works fine. Also, when I start it manually via systemd (systemctl start freeswitch), it still works fine. However, when I enable freeswitch.service to start automatically and reboot, the freeswitch log shows 503 errors trying to register out to my gateway, and my internal client (an Obi200) gets a 503 when trying to register in to FreeSWITCH as well; this keeps happening repeatedly (waiting 30 seconds and then failing again). However, if I restart the service (systemctl restart freeswitch), connectivity then starts working. Would the 503 be what's reported up if there's no network connectivity either way? I'm using the Debian systemd *freeswitch.service file (with very minor tweaks for my configuration on Arch Linux). Has anyone encountered this problem before (on Debian, Arch Linux, or elsewhere)? The overall .service file is very similar to sshd.service, which doesn't have connection problems, so my guess is there's something specific to FreeSWITCH going on. If this is Arch Linux-specific and I ask in their forums, is there anything different about how FreeSWITCH handles connectivity (perhaps caching some kind of handle) that would help point things in the right direction? Thanks, David

Unable to detect beep with mod_avmd
by Aqs Younas 25 Feb '16

25 Feb '16

Hi, I am using avmd to detect beep over a channel. Beep is generated by below script. <extension name="10014"> <condition field="destination_number" expression="^1001$"> <action application="playback" data="tone_stream://L=5;%(500,6850,850)"/> <action application="hangup"/> </condition> </extension> and starts avmd on fs_cli as. freeswitch@debian>avmd 30d99731-4ff3-4f02-ad4b-85a3a8b9d600 start I could proper hear beeps over the phone but does not see avmd detecting this. Does not see anything like "beep detected" in logs. I am made several attempts but unable to detect beep even a single time. Is there something wrong that i am doing? Thanks in advance.
