FreeSWITCH employment opportunity in Brevard County, FL
by McKnight, Jeffrey 13 Jan '15

13 Jan '15

Brevard County, (in Florida) with about 3000 employees, has been evaluating FreeSWITCH as a replacement for county wide legacy telephones for almost a year now. The system is almost completely feature functional in comparison to our Nortel system, however our FreeSWITCH expert has found more profitable employment elsewhere. We are testing the waters to see if there is anyone in the local area that would be interested in completing the perfection of a couple of features, assisting in the rollout of this system county-wide, and maintaining this system. This would be a full time employment position, good benefits, and great longevity. Please email me directly at Jeffrey.mcknight(a)brevardcounty.us if there is any interest. Regards, Jeff McKnight ----------------------------------------- Under Florida Law, email addresses are Public Records.

Hello, We have a freeswitch installed behind opensip which handles registration. We'd like to turn on and off MWI and cisco phones. When we use the following lua code, it will fail. We also tried using fs_path but it did not work.

by Bruce Lefko 12 Jan '15

12 Jan '15

Is there a way in mod_spandsp to allow for g711 fallback in calls where t38 negotiation fails? I would like to not have to call a number back with fax_enable_t38=false and have the call continue with audio fallback. Thanks!

Record sound quality not good but pcap is quite good
by Ali Pey 12 Jan '15

12 Jan '15

Hello, I use record to record part of a call and sometimes I get some static noises and distortion; however when I listen to the call on pcap capture, it's quite clear and no noise. I record to a wav file and then use sox to convert it to ulaw. Any suggestions? Any help would be greatly appreciated. Thanks, Ali Pey

files.freeswitch.org

We migrated this instance to a new container today, If you see any weirdness in downloads please report them ASAP, I've also re-enabled IPv6 on files dot. Our allocation is accessible from both HE and Cogent. If anyone has Cogent allocations please do what you can to apply pressure so that Cogent will peer with HE solving the issues with the partitioned IPv6 network. HE is willing to peer, its Cogent that is refusing.

Auto Changing stun/rtp/dtls port every second?

Auto Changing stun/rtp/dtls port every second? Just built from master FreeSWITCH Version 1.5.15b+git~20150109T000119Z~d199060249~64bit (git d199060 2015-01-09 00:01:19Z 64bit) And when connecting with chrome web-rtc thru sip.js I noticed switch appears to be changing or flipping ports every second bouncing between them. Happens with Chrome, But not Firefox. 2015-01-10 01:57:22.095932 [NOTICE] switch_rtp.c:1139 Auto Changing stun/rtp/dtls port from xx.xx.xx.xx:42748 to xx.xx.xx.xx:42751 2015-01-10 01:57:22.535937 [NOTICE] switch_rtp.c:1139 Auto Changing stun/rtp/dtls port from xx.xx.xx.xx:42751 to xx.xx.xx.xx:42748 2015-01-10 01:57:23.095959 [NOTICE] switch_rtp.c:1139 Auto Changing stun/rtp/dtls port from xx.xx.xx.xx:42748 to xx.xx.xx.xx:42751 2015-01-10 01:57:23.495890 [NOTICE] switch_rtp.c:1139 Auto Changing stun/rtp/dtls port from xx.xx.xx.xx:42751 to xx.xx.xx.xx:42748 2015-01-10 01:57:23.995945 [NOTICE] switch_rtp.c:1139 Auto Changing stun/rtp/dtls port from xx.xx.xx.xx:42748 to xx.xx.xx.xx:42751 ..continues on every second for duration of call.

Strange noise when using conference_set_auto_outcall
by Oleg Stolyar 12 Jan '15

12 Jan '15

Hi guys, When I use conference_set_auto_outcall to dial a PSTN number via a SIP trunk (Level3 is the provider), the existing conference participants start hearing noise after a couple of seconds. It happens whether at that time the line is still ringing or the PSTN party picked up.. The noise persists through the session when the PSTN party is silent. The noise does not happen when I use the simple bridge to dial the PSTN number instead of a conference, so I don't think it's the PSTN provider's fault. On the other hand, when I use the same settings to outcall another FS server, the noise is not there. Is there some conference setting I am missing? Has anyone been able to successfully use set_auto_outcall to call PSTN numbers? I am on FreeSWITCH Version 1.5.14b+git~20140730T171747Z~5075d4af0d~64bit (git 5075d4a 2014-07-30 17:17:47Z 64bit) I am trying to reproduce this on the latest master but having trouble building on my old CentOS 5.9. I'll keep trying.

Freeswitch + serial forking at opensips
by John Nash 12 Jan '15

12 Jan '15

Hello, I am facing an issue when using opensips to serial fork Invites to some SIP gateways and using freeswitch in the middle as b2bua to send calls. That means if first Invite fails opensips will pick next available gateway and append branch to send this again to freeswitch. But I have noticed when first gateway sends a failed response (and freeswitch log shows call destroyed) and second invite is sent (Same call id, cseq but different branch tag) , freeswitch seem to have old transaction alive and sends 482 Request merged response. I saw in mail archives that it was discussed few years back but there was no conclusion. Is there a reason freeswitch keeps transaction alive (for 4 seconds I think) even if it received "ACK" for failed response? Regards John
