static rtpmap entries are not shown in outbound invites
by Leon de Rooij 08 Mar '11

Hi, When I'm using late negotiation and in my dialplan do the following: <action application="export" data="codec_string=${ep_codec_string}"/> <action application="set" data="inherit_codec=true"/> (I also tried with absolute_codec_string instead of codec_string) Then the codecs (or more precisely said, the rtpmap lines) that are offered in the SDP of the A leg are not offered to the b-leg. Only the RTP payload numbers as defined by IANA are there in the media (m) header. For example: a-leg SDP in INVITE: m=audio 16864 RTP/AVP 18 101. a=rtpmap:18 G729/8000. a=rtpmap:101 telephone-event/8000. b-leg SDP in INVITE: m=audio 24148 RTP/AVP 18 101 13. a=rtpmap:101 telephone-event/8000. Is there a reason why FS removes the G729 rtpmap, even though I exported all into the codec_string chan var ? Now, this would normally be fine because G729 being 18 is a static rtpmap, but I have one endpoint that has the behavior that if I send an invite with RTP payload 18 and omit the rtpmap being G729, then it responds with a 183 session progress containing rtpmap G.729 (notice the dot) - this is wrong as far as I can tell. Apparently they respond with the correct G729 (without the dot) in their 183 sess progress if I include the rtpmap in my invite. I believe I read somewhere there was an option settable (on a sip profile?) that enables to always send all payloads as defined in the media (m) sdp header as a=rtpmap lines, but I cannot find the option anymore (or perhaps I'm mistaken and saw it somewhere else ?) Can someone help me with this ? Thanks & kind regards, Leon

Google Voice integration with FS works fine. but sending fax seems not working. 12068235374 is a K7 number, If I dial it , I can hear fax machine answering sound. In fact, people has used GV to send fax via fax machine. ( http://www.magicjacksupport.com/faxing-via-google-voice-t7412.html) Is this problem related with mod_dingaling? please take a look! thanks itch@internal> originate

whistlephone on freeswitch
by Stavros Spiliadis 08 Mar '11

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

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.

Hello all, According to wiki: http://wiki.freeswitch.org/wiki/Mod_lua#session:originate I can use: "session:originate" command in LUA script to originate new session, but I can't understand how should I do it and can't find any example how I use this command. Can you help, guys? Thanks, Dmitry.

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

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
