FreeSWITCH using outbound proxy but to bypass media
by Muhammad Naseer Bhatti 28 May '16

28 May '16

I am trying to use an outbound SIP proxy for FreeSWITCH by adding fs_path to the bridge. It’s working fine and I am able to send calls using the proxy. On the proxy (which is also FreeSWITCH) I am receiving the call in a lua script, create a new session with the destination gateway and bridge two sessions (old, incoming and the newly created) The idea is to have multiple FreeSWITCH servers (all public IP address) originating calls while all calls going to the carrier via the proxy. The problem is that all media is also passing through the proxy. Is there a way I can only send signaling through proxy and media to flow directly between the endpoints? I have tried bypass_media and bypass_media_after_bridge but it’s not working. Is this even doable? Thanks. -- Muhammad Naseer Bhatti

Fax....How I hate you.
by Blake Priddy 24 May '16

Is anyone out there having success with sending/receiving faxes with Flowroute? I have an SPA 112 and I am getting just the tops of the faxes. I have referred myself to this document https://wiki.freeswitch.org/wiki/SPA2102_T38_Howto with no success. I was just wanting to see what everyone is doing out there with flowroute for the people who still must use faxing.. -- *Blakelund Priddy* Network & Systems Engineer Bryant Public School District Bryant, Arkansas 72022 http://www.bryantschools.org p 501-653-5038 f 501-847-5656

Using freeswitch as Generic SIP SBC/RtpProxy without predefined endpoints
by Taisto Qvist 14 May '16

14 May '16

Hi, I am an OpenSIPS/Kamailio user that has spent the whole day trying to figure out which software is most suitable to build an SBC that only acts as a full b2bua with rtp-relay, with an undefined number of destinations(entire domains with lots of unknown proxies) on each side. I've been looking at yate, freeswitch, SEMS, but I am overwhelmed by the gazillions of configuration-files that seem to be needed. I have absolutely NO need of pbx/user functionality, just a B2BUA and rtp-proxy capabilities(with full codec-transparency), with the addition that I must be able to add some custom logic to decide the DNS or IP(v6) address of the next-hop sip-node. All examples I've found on freeswitch SBC config, has predefined gateways/trunks/proxies as "predefined next-hops", and I want the SBC to be able to send anywhere, depending on custom application logic. I'd stick with kamailio/rtp-proxy and the standard topology-hiding module, but unfortunately I need the full topology hiding of a b2bua. Is this easily achievable with Freeswitch? Any help with be immensely appreciated! Regards Taisto Qvist

Is MySQL OK to use?
by Alex Lake 06 Apr '16

06 Apr '16

I find these "Error in my_thread_global_end()" messages somewhat annoying in my fs1.2stable on Ubuntu12.04 box. Is there any advice (other than "don't use MySQL") for how to install it better? Might it be something to do with thread-safe libraries (I'm using libmyodbc_r.so at the moment)

FS behind NAT
by Tao Zhang 14 Mar '16

14 Mar '16

Hi all, I have been tracking down why my FS verto video conf demo setup not working. Now I believe the reason is my FS server is behind a NAT. My previous posts may be misleading now, so I am creating a new thread. Some evidence I saw: 1) In the SDP dialog, I saw my FS server's internal IP got used, rather than its public IP, for example Dialog 6c62f631-469c-a2f0-e484-6e9cfcda7eedANSWER SDP v=0 o=FreeSWITCH 1444254094 1444254095 IN IP4 10.240.15.244 s=FreeSWITCH c=IN IP4 10.240.15.244 <============= t=0 0 2) Also, in wireshark , I saw my client is trying to send STUN packets to the FS server's internal IP, 450 18.252726000 192.168.1.7 10.240.15.244 STUN 158 Binding Request user: mlvLvmDzCphyQYz5:N3MZoB99aGiAZotr So now my questions are Will the verto video conf demo work when the FS server is behind NAT? If so, could someone help me with the necessary config changes and etc.? Thanks so much! Tao

Mod_callcenter ODBC vs File
by Jai Rangi 11 Feb '16

11 Feb '16

Hello, FS version: FreeSWITCH Version 1.4.18+git~20150312T185523Z~4eed221b69~64bit (git 4eed221 2015-03-12 18:55:23Z 64bit) I found a very strange behavior on mod_call center when used with odbc. This was easy to reproduce when the agents are busy and new calls come in. New member goes in abandoned state immediately and stay in same state forever. Even if previous call is complete and Agent is in Waiting state. Infact some times new members go in abandoned state immediately even if the agents are available. Everything works perfect once I changed the mod_callcenter.conf.xml config to file only mode, new calls go in Waiting state and call is connected to agent as soon as the agent is free. Any idea why the new member goes in abandoned state randomly in place of being in waiting state? Can it be due to too small timeout in call center module as it query the DB every time? Can that be changed? Anyone else had smiler problem, any experience or any recommendations will be much appreciated. Thank you, -Jai

Random calls failing with WRONG_CALL_STATe when using TLS
by Emrah 26 Jan '16

26 Jan '16

Hi all, I am facing a very frustrating issue. I often have to dial twice when using my Yealink phone with TLS because the first attempt times out. The logs on the Yealink indicate that the first invite is successfully received, to which my FS sends a 100 trying and 407 proxy auth required. It is subsequently when my phone sends back the invite that the connection crashes with the following error: SSL ERROR SYSCALL Is this something common? Why does the SSL connection crashes when the phone attempts to send the second invite? My phone is behind NAT. It is going to be a crazy expedition to collect the logs and Pastebin them, so I am tempting my luck on the list first to see if you have any pointers. As a last piece, my Bria on my iPHone, among other clients, never had this issue. I did experience it from time to time with Blink on Mac OS X. Any help appreciated. Emrah
