Modems
by Ken Gillett 20 Sep '10

20 Sep '10

I asked this before, but never got any response, so hope someone can help me this time. Is it possible to use a (USB) modem as a 'trunk' to and from the PSTN, i.e. be able to accept incoming PSTN calls and also make PSTN calls? I plan on installing FreeSwitch on a Mac and it would be really handy to be able to use Apple's USB modem in this way as otherwise there's no way to add such PSTN functionality on the Mac Mini. Although my requirement is Mac based, I guess this question applies to any FreeSwitch installation. Ken G i l l e t t _/_/_/_/_/_/_/_/

Problems with FAX transmission
by Jan Riedinger 20 Sep '10

20 Sep '10

I'm trying to send a fax via our Freeswitch switch without success. It seems that the "invite sdp (t38)" message isn't forwarded from the gateway of the fax receiver to the gateway of the fax sender. See the attached tif file with the Wireshark trace. If I try the fax transmission with the same setup with a commercial softswitch (same fax equipment, same sending and receiving gateways), the fax transmission is successful. We are using the following settings in the sip_profile <param name="inbound-codec-negotiation" value="greedy"/> <param name="inbound-late-negotiation" value="false"/> Does anybody know what's going wrong?

Is curl.run() blocking until a result is got
by Storm Demo 20 Sep '10

20 Sep '10

Dear All, In the below example from FS wiki, can I be sure that "my_callback" will be called before session.hangup() is excuted? Thanks a lot Jasper use("CURL"); function my_callback(string, arg) { console_log("info", string); return true; } if (session.ready()) { session.answer(); var curl = new CURL(); curl.run("POST", "http://www.freeswitch.org/curltest/", "foo=bar&this=has+spaces+in+it", my_callback, "my arg\n", "user:s3cr3tpw"); session.hangup(); }

Re: [Freeswitch-users] sip stack problem in fsw
by JRichey 20 Sep '10

20 Sep '10

I'm in a similar situation where I need to disable VAD because the other end will disconnect the call if the RTP stops. I've tried the setting Anthony suggested as well as several others I've found on the wiki, but I've not been able to get it to work. The variables I've been trying are listed below. suppress-cng suppress_cng rtp_disable_vad_out rtp_disable_vad_in bridge_generate_comfort_noise send_silence_when_idle For my test calls I'm just playing back sound files with sleep in-between them and I see no RTP when calling sleep. I'm using tcpdump and wireshark to analyze the calls. -Justin Richey jrichey(a)ITLtd.net -----Original Message----- From: freeswitch-users-bounces(a)lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org]On Behalf Of covici(a)ccs.covici.com Sent: Saturday, September 18, 2010 1:26 AM To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] sip stack problem in fsw Thanks for the suggestion -- unfortunately it did not work -- I put it in the internal profile, but it seems to have had no effect.

question about VMD
by Eric 20 Sep '10

20 Sep '10

Hi, I need somebody help me on this. Based on my currently knowledge, the way to detect Answering machine(AM) is about guessing if a live person picks up or the AM plays voice prompt. Normally the detection algorithm monitors the first a few seconds of audio on the line, then tries to guess live person or AM based on certain patterns, like find several seconds silence, this is the way Dialogic using, it is not perfect though. Is FS has the similar function todo this instead of detecting the BEEP? Thanks! 2010-09-20 Eric

New to freeswitch: Tetris

Hi all, Am new to freeswitch and telephony. I installed freeswitch, and only changed acl.conf.xml to allow SIP calls from my IP address. So, my first test call to 9198 is not playing the song back, here is the log. Anything more i need to do?

server failure
by marian szczepkowski 20 Sep '10

Hi From what I can gather the idiots who wrote SIP decided that a server is a never a point of failure, x.25 and all other telecommunication protocols I have had experience with are able to recover from a remote end error/restart. All I can find with SIP is a daft time out in the device to perform a re-registration request, and until that time the unit is unable to make a call. Am I missing something or do I have to go jump through hoops with my phone code to re-connect to a server after a server failure.
