Two FreeSWITCH Box IVR Call Transfer
by Jigar Thakkar 09 Jul '10

09 Jul '10

Hi Guys, I am a beginner to FreeSWITCH. I have few questions. 1. What is the difference between BRIDGE, ORIGINATE and TRANSFER. 2. I have two FreeSWITCH box. BoxA and BoxB 1. User will make a call to BoxA; BoxA's IVR collect some information i.e. userid and pin. 2. Now BoxA will forward/transfer/bridge call to BoxB's IVR ( here i want to pass userid as channel variable) 3. Box B will ask for another pin i.e. pin2, verifies the same and pass whether pin2 is correct or not to BoxA (also transfers the call to boxA's ivr) 4. Box A shall play message to User whether this process is successful or not. And then call shall be hanged up. My work till date is 1. setup the two freeswitch ivr, box a and box b. 2. I wrote .net code to handle the individual role. i.e. to ask user id and pin 3. I facing the problem in forwarding a call from boxA to boxB along with the userID Please suggest the best way to implement it. I hope I have explained the scenario properly. Thanks & Regards, Jigs.

FS 1.0.6 on EC2 - no audio on outgoing calls
by paul gore 09 Jul '10

09 Jul '10

Hi there, I am experimenting with FS on EC2, I like results, but stuck on weird audio issue - I followed FreeSwitch EC2 wiki article and modified internal profile and vars.xml accordingly, but unfortunately still cannot get it working. Incoming and outgoing calls made using a SIP phone to FS extensions work just fine. As well as calls to FS from PSTN. But calls to PSTN via gateways result in no audio at all, no ring, nothing, SIP signaling goes through OK. Sofia status profile shows correct values for Ext-RTP-IP for both profiles - my static public IP, RTP-IP shows local IP. Any thoughts on that? Anybody can share working profile configuration may be? Please help, I really need to get this going. Thanks.

Contact Header Modification
by Roger Salloum 09 Jul '10

09 Jul '10

Is it possible to modify the contact header such that it is the caller id? I noticed sip_contact_user but it does not seen to effect the outbound leg of the call. The documentation specifically mentions that it is only for the internal SIP contact so I don't believe it does what I was hoping it would. I know you are able to set it to a static value, but I was hoping to be able to set it on a call per call basis. Thanks

Re: [Freeswitch-users] enforcing RTP payload numbers for codecs

No, you can't force codecs in the dynamic range and if properly implemented, it won't matter what number either side chooses.

If I could have enforce FS to transcode that session between those two clients it would have work properly (currently experiencing half duplex).

More questions migrating from Asterisk to FS
by mazilo 08 Jul '10

08 Jul '10

I recently managed to get FS to run on my Seagate DockStar device. So far, I have no problem to configure my FS with a single Gizmo5 account, except losing the 1st two seconds at the beginning of a call connection (I am sure there is a fix to this, but haven't found one, yet). My first step is to move all my Gizmo5 accounts to my new FS system so that I can decommission my Asterisk PBX system. The question I have is if FS has a support for template with inherritance (like asterisk) so that I don't have to copy the same parameters for each Gizmo5 account, except the username/password. I apologize if this question had been asked before, but a search through mailing list couldn't did not seem to yield such a topic. Thank you. ----- don't and stop are the ONLY two 4-letter words considered offensive to men, but not when used together. -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/More-questions-migrating-from… Sent from the freeswitch-users mailing list archive at Nabble.com.

Re: [Freeswitch-users] hangup does not break the Lua loop
by Anthony Minessale 08 Jul '10

Also session:ready will return false if the call is being transferred. Bottom line is you should always be checking session:ready on any loops and periodicly throughout your script and exit asap if it returns false.

mod_spandsp wiki error
by Joseph L. Casale 07 Jul '10

07 Jul '10

The wiki states in the Intro: The old mod_fax, mod_t38gateway, and many of the codecs in FreeSWITCH (mod_voipcodecs) have now merged to one module called mod_spandsp which takes advantage of all the DSP features found in the spandsp library including T.38 endpoint and gateway functionality. Yet the "Installation and configuration" states: mod_spandsp is compiled by default with the freeswitch source tree but is still in testing stage to use it just unload mod_voipcodecs and mod_spandsp and load mod_fax remember to change it in modules.conf.xml mod_spandsp require libtiff. Is that an error, should I fix this? If the old mod_fax, mod_t38gateway and ... modules have been renamed and mod_spandsp is in modules.conf.xml there is nothing to do then? Thanks, jlc
