No audio on both sides. Call is made and received successfully but there is no audio.

Hi All, I installed FS on *VM*(Ubuntu) running on a window server. I have Twinkle softphones installed on 2 different machines in same network. Both twinkle softphones are registered and connected to FS. When I make a call from one twinkle to other, Call is successfully made and received. But there is no audio on any side. then Call is disconnected after 32 seconds automatically. I logged a defect on JIRA but its closed. They say its a Network issue. I have pasted the *siptrace* log here --> http://pastebin.freeswitch.org/22780 JIRA link -> https://jira.freeswitch.org/browse/FS-6618?filter=-2 Let me know if more trace/log/info is required. Please suggest me what needs to be done in order to mitigate the problem. -- Anurag Rana http://newbie42.blogspot.in/ On the trampoline of life's experiences, Striving towards a saintly life in the midst of these materialistic turbulences.

A leg not able to hear the user busy message using bridge_early_media
by lakshmanan ganapathy 22 Jun '14

22 Jun '14

Hi everyone, I'm using freeswitch stable version 1.2.23 with wanpipe 7.0.8 and libsng_isdn-7.29.0. Recently I faced a issue with regard to early media not been sent to the A leg. The scenario is, 1. There is an incoming call. 2. From dialplan, trying to bridge with another number as follows. <action application="bridge" data="{ignore_early_media=false,bridge_early_media=true}freetdm/1/a/99522xxxxx/> 3. Now when the B leg starts ringing, the A leg hears the "ringback" ( which means bridge_early_media works ). 4. B leg rejects the call. So TELCO sends a PROGRESS message normally saying "The number you are trying to reach is currently busy etc...". 5. The A leg was not able to hear the above said message, and it hears only the "ringback". 6. Then finally TELCO sends a DISCONNECT, and the A leg got hungup. Some one please tell what I'm missing in this?, Is there some other variable to set?. Please help. Attached the freeswitch.log and the pcap files.

No audio on both sides. Call is made and received successfully but there is no audio.
by Phil Quesinberry 22 Jun '14

Hi Anuraq, Welcome! Now the fun begins. At first glance it looks like you probably need to forward the RTP ports to FS. I believe the default port range is 16384 to 32768 and that setting should be in <FS-dir>/conf/auload_configs/switch.conf.xml. RTP is what the media (audio/video) goes over. Your two phones are on the same network but FS is on a different subnet, and looking at the SDP, FS is proxying the audio from that different subnet, (the default behavior) so those ports will need to be forwarded. Make sure that those ports are allowed through Ubuntu's firewall as well. You may want to consider tightening up the default RTP port range so the ports you need to forward don't conflict with anything else. I believe that you'll need two for each channel, so change it to whatever works for your intended setup and forward those ports to the FS box, I'd probably reduce the range to 512 or 1024 ports but that's just me. It appears that you're already forwarding SIP port 5060. If you want FS to accept calls from "outside" (A DID for example), then you'll want to forward port 5080 as well with the default setup. If you want to enable TLS, additional SIP profiles, etc. then you'll need to forward additional ports. Cheers, - Phil _____ Hi All, I installed FS on *VM*(Ubuntu) running on a window server.

First build completed with many warnings
by Keith Goggin 22 Jun '14

22 Jun '14

Hi List, I've managed to build 1.2.24+git~20140617T204847Z~9dde4b1548~64bit (git 9dde4b1 2014-06-17 20:48:47Z 64bit) on Linux Mint 17 AMD E-350 dual core and 3.6 GiB memory, it booted up and shut down OK. I'd like to try again with fewer options enabled in the hope of a quicker build and getting a handle on the very many warnings and possible error messages involved. Can someone suggest some config changes to achieve this outcome? I have used <https://wiki.freeswitch.org/wiki/Installation_Guide#Recommended:_Git> and the wiki generally to get this far but am struggling to understand the warnings and don't know which options to pick for a very light weight and basic SIP server for no more than 5 or so users. I'm not sure about the policy on attachment of logs but I'll risk the first two pages of bootstrap.sh console output. Any help appreciated.

Why a call hangs up without warning during recording
by Clive Lansink 22 Jun '14

22 Jun '14

Hello. I've noticed in a Freeswitch IVR application I've been working on that when the customer phones in to record a message, the call is hung up without warning after about five minutes. This does not happen when I call in locally. When this happens, the log just shows there was a hangup with normal clearing. But the customer didn't hang up. The customer just notices visually that their phone hangs up so the hangup seems to be caused somewhere between the two systems. I figured that during a recording, Freeswitch is not generating any audio at all, and it could be that something in the public phone system times out after absolutely no audio for a period of time. I have come up with a work around by getting Freeswitch to generate a short tone repeatedly during recording, like 50Hz at -30dB so it is basically inaudible, every thirty seconds or so. This seems to have solved the problem and now the customer can record for as long as he wants. But I suspect this is really a work-around and not the recommended approach. I did play with the suppress cng parameter in the sofia configuration but didn't find any setting that would solve the problem. Thankfully my work-around has got me home in the meantime but I would appreciate any comments on this. Does nobody make long recordings these days? Cheers.

IPV6 addr change killed sofia profile internal
by Mario G 21 Jun '14

21 Jun '14

I have a mix of native IPV4/6. A mac runs FreeSWITCH using a static IP4 address and has IPV6 addresses. For some reason (I am not an IPV6 expert) the IPV6 address changes once or twice a day. Everything on the mac runs fine except FreeSWITCH stops all the profiles then restarts them, it then loses the internal profile. The sequence is below, If anyone knows of a FS param or something I can use to workaround this please let me know. BTW, I am not using IPV6 to the external ITSPs, but the Yealink phones have it on, I could turn it off but was hoping for a real solution. Thanks, Mario G 1 - Log shows: [INFO] mod_sofia.c:5286 IP change detected []->[] [2601:9….. 2 - FreeSWITCH stops all 7 external profiles and the internal profile. 3 - All profiles are restarted, but only the external ones start successfully. The internal does not start because the port has not been freed by OS X yet. And FreeSWITCH never attempts to restart it again. I am sure this is related to Jira http://jira.freeswitch.org:8080/browse/FS-5223 but is a bigger problem since I have to turn off IPV6 to stop it. 4 - I have to "sofia profile internal start” to get it going again. PS: Would love to find a way to get FS to keep trying to restart internal rather than give up, would help both problems.
