whistlephone on freeswitch
by Stavros Spiliadis 08 Mar '11

Ok, Here is what I did. I copied the 5 (five) whistelphone proxys to the freeswitch SIP_Accounts config file as explained here » wiki.freeswitch.org/wiki/Provide···tlePhone<http://wiki.freeswitch.org/wiki/Provider_Configuration:_WhistlePhone>. All 5 instances are reported as registered (REGED) under Status--SIP_Status. So far so good. Incoming calls work fine and quality of sound is good. Outgoing calls give the "... I'm sorry but I cannot complete your call." Any ideas on what I'm doing wrong, Suggestions? Thank

Re: [Freeswitch-users] send fax via google voice.
by JRichey 08 Mar '11

I'm with Ken, faxing needs to die. Of faxes being sent now, I wonder how many originate and/or terminate via a fax to email gateway. These and the possibility that your call will be sent via VoIP somewhere along the way should strip away the false idea that faxing is secure because it travels over the PSTN. The OP is testing to K7, which is in part a fax to email service. Incidentally, the system that terminates K7 faxes is a FreeSwitch box. :-) -----Original Message----- From: freeswitch-users-bounces(a)lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org]On Behalf Of envelopes envelopes Sent: Monday, March 07, 2011 1:06 PM To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] send fax via google voice.

txfax bug?
by Dmitry Saratsky 07 Mar '11

07 Mar '11

Hi All, I have some LUA script that designed to send faxes. If I originate session from within lua in the following way, all ok (fax can be sent successfully), but I see annoying error log in console... why? Relevant part of LUA script: local new_session = freeswitch.Session(); new_session:originate(session, "{autohangup=false,sip_cid_type=rpid,absolute_codec_string='PCMU,PCMA',origination_caller_id_name=" .. fax_caller_id .. ",origination_caller_id_number=" .. fax_caller_id .. "}sofia/gateway/sip1.myprovider.com/" .. fax_dst_num .. "|sofia/gateway/ sip2.myprovider.com /" .. fax_dst_num, 20); new_session:execute("txfax", outgoing_fax_path .. fax_tiff_file .. ".tiff"); repeat new_session:sleep(1000); until ((new_session:ready() == false) or (new_session:getVariable("fax_result_code") >= "0")) new_session:hangup(); Error log: 2011-03-08 01:24:02.289821 [ERR] switch_ivr.c:481 Invalid Command! According to my investigation, I can say for sure, that reason for error log in console is following line in my LUA script: new_session:execute("txfax", outgoing_fax_path .. fax_tiff_file .. ".tiff"); Yes, I know that all docs says to use txfax function in lay like: "originate sofia/external/100(a)10.10.10.10 &txfax(/path_to_fax_file)", but from other examples for "rxfax" I decided to do it in my way. It is even works perfect... So, why I still see error for this? Thanks, Dmitry.

What is so dangeres in "freeswitch.msleep()" in LUA?
by Dmitry Saratsky 07 Mar '11

07 Mar '11

Hi All, According to: http://wiki.freeswitch.org/wiki/Mod_lua#freeswitch.msleep It is not good to use: "freeswitch.msleep()" in session-based script: NOTE: Do not use this on a session-based script or bad things will happen. Can anyone explain please why not and what does author mean with "session-based script". I want to use it inside some function between I originate session and hangup it in the following way: repeat -- os.execute("sleep 1"); freeswitch.msleep(1000); until ((not new_session:ready() == true) or (new_session:getVariable("fax_result_code") >= "0")) new_session:hangup(); Is it danger for me to use this?

Avoid Loops
by Stephen Wilde 07 Mar '11

07 Mar '11

In some situation there are calls that loops among some providers and I want avoid that situation. For example, I receive the call from my client A, I send this call to my provider B but for some reason the call return to me (for example because B sends the call to A and A resends the call to me). In case of loop for me the solution can be simply to drop the call so my client can reroute to a different provider. There is anyone that can suggest me a way to drop looped calls? Stephen

DTMF not taken into account within a conference
by John Smith 07 Mar '11

07 Mar '11

Hi all, I have an issue with DTMF within a conference with the latest versions of FS. When I enter a DTMF within a conference it only works the first time. For example if I press 0 I’m muted but afterwards my DTMF commands are not taken into account whatever I press. I checked the logs and I have just mention for the first digit received: switch_rtp.c:3237 RTP RECV DTMF 0:800 This issue seems only appear within a conference. I tested IVR demo and it worked fine. Before entering the conference, everything works also fine: all the digits are received by FS. I tried many recent builds and I always got the issue. I made tests today with the latest git HEAD and I still have the problem. I don’t have this issue with FS V1.0.6: all DTMF entered are taken into account. I use exactly the same configuration and the same SIP client. Has anyone an idea of what is going on? Thanks John

As some of you may already know, Scientific Linux 6.0 has been finally released. (March 3 2011 to be precise.) Scientific Linux 6 is a RHEL 6 clone. Surprisingly CentOS 6 should also a RHEL 6 clone. If anyone wants to have a go to see how FreeSwitch runs on a RHEL/CentOS 6 like box, then by all means, finally there is a RHEL 6 clone that should be fully compatible with the upstream sources.
