How do you install the AMQP module?
by Hinchy, Martin 29 Mar '17

29 Mar '17

Hi guys, I have just installed FreeSWITCH on a Windows 7 x64 PC using the Windows msi 64-bit installer. The installation worked fine and I have been able to make calls through the switch. It appears though that the AMQP module (mod_amqp.dll) is not included in a standard install. It does not appear in the C:\Program Files\FreeSWITCH\mod folder. Does anyone know where I can get this module from? Regards Martin Queensland Rail's number one priority is safety. Queensland Rail has a program of testing for alcohol and illicit substances.

Freeswitch not offering VP8
by Jack Loranger 29 Mar '17

29 Mar '17

We are running FreeSwitch on a 2012 windows server. Trying to get Video conferencing to work with verto. Freeswitch is not offering VP8, when I do a "show codec" it is not listed. I read that it is in the core now. libvpx is compiling alright. Is there something I have to do to activate it? Here is vars.xml configuration: <X-PRE-PROCESS cmd="set" data="global_codec_prefs=PCMU,PCMA,GSM,G722,7221@32000h,G7221@16000h,OPUS,VP8,H264"/> <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=PCMU,GSM,PCMA,OPUS,VP8,H264"/> Thanks for your help!

CoreSession::hangup after MOVED on IVR calls
by Piccinin Francesco 29 Mar '17

29 Mar '17

Hi all, we are experiencing a call drop issue when users configure call forward unconditional on their extensions. Call drops when these extensions are reached from pstn and through an IVR post selection. Freeswitch recived a SIP 302 Moved from these endpoints, call are processed on sip_redirect_context but freeswitch first send a SOFIA DESTROY to forwarding extension (correct) and then KILL A-leg (IVR) with the following error: CoreSession::hangup It seems freeswitch does not keep alive a-leg in this scenario. Can you please help us? Thanks Francesco

hangup a call with a specific reason
by Caragea Silviu 29 Mar '17

29 Mar '17

Hello, In case of an incoming call from PSTN to FS that is bridged to a user, if user is not answering in 60 seconds FS will close the call with 480. I find in config how to configure this timeout to larger value but I didn't found anything on how to overwrite the reason in 486. Some carriers are rerouting the call over and over again in case they get 480 and behavior sucks for the users Silviu

FreeSWITCH not answering some REGISTERs
by David Ponzone 28 Mar '17

28 Mar '17

All, I noticed recently that sometimes FS (1.6.6) does not honor REGISTER or OPTIONS requests coming from some customers. Those customers register every 30 seconds, and FS does not answer to around 20-30 REGISTERs each day. I am trying to understand that, as the server is far from loaded (max 100 concurrent calls on a Dell R610). Can anyone recommend some debugging steps to try to narrow this down ? Any known issue of this sort in 1.6.6 ?
