Conference recording pause/resume problem
by Mariusz Czulada 13 Jul '12

13 Jul '12

Hi, I try to prepare a patch which allows to pause/resume a given recording. I'm in the middle of the road: pause is working, by resume - not :(. I'd like to ask for your help in finding a problem. I'm not sure if I handle member and file flags in the thread sub correctly. BTW. I lost some time playing with member-fnode until found fh in conference_record_thread_run is a proper handler. What is the conference_file_node_t member->fnode used for, if not for handling a recording file? Regards, Mariusz

Absolute conditions are not changing the proceed variable... (mod_dialplan_xml.c)
by Rafael Vargas 01 Feb '12

01 Feb '12

Hi, I've noticed that when I have an extension containing only an absolute condition, the proceed variable in mod_dialplan_xml.c:parse_exten(...) is not changed and the next extension is also executed, thus ignoring the first extension's "continue" attribute, which was set to "false". I'm referring to this code: (mod_dialplan.c:221 in today's GIT) ... } else if (time_match == -1) { switch_log_printf(SWITCH_CHANNEL_SESSION_LOG_CLEAN(session), SWITCH_LOG_DEBUG, "Dialplan: %s Absolute Condition [%s] match=%s\n", switch_channel_get_name(channel), exten_name, all ? "all" : "any"); pass++; if (!all && !xor) break; } else if (time_match == 1) { ... Shouldn't this set the proceed variable to 1, just like the regex condition a few lines above (line 208 in today's GIT)? I just made a quick test and it worked as (I) expected. What I'm proposing is to change the code above to the following: ... } else if (time_match == -1) { switch_log_printf(SWITCH_CHANNEL_SESSION_LOG_CLEAN(session), SWITCH_LOG_DEBUG, "Dialplan: %s Absolute Condition [%s] match=%s\n", switch_channel_get_name(channel), exten_name, all ? "all" : "any"); proceed = 1; pass++; if (!all && !xor) break; } else if (time_match == 1) { ... Sorry if this was already discussed, I've searched this list and the users list to no avail...

switch_stun_random_string returns identical strings on two calls randomly
by Seven Du 01 Feb '12

01 Feb '12

Hi, I tried to replace the following function which I copied somewhere in msrp.c with switch_stun_random_string (http://docs.freeswitch.org/group__stun1.html#geb124530a232d65edc508afd1b9dd…) but I found sometimes switch_stun_random_string (http://docs.freeswitch.org/group__stun1.html#geb124530a232d65edc508afd1b9dd…) returns identical strings on two sequential calls, with the following function I never found, so I still use it. By looking the code I understand srand seed is time based so it's possible to return duplicate random string, but I found switch_stun_random_string (http://docs.freeswitch.org/group__stun1.html#geb124530a232d65edc508afd1b9dd…) used in some places other than stun, just curious would it cause problems? void random_string(char *buf, switch_size_t size) { long val[4]; int x; for (x = 0; x < 4; x++) val[x] = random(); snprintf(buf, size, "%08lx%08lx%08lx%08lx", val[0], val[1], val[2], val[3]); *(buf+size) = '\0'; } Thanks. -- About: http://about.me/dujinfang Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn Sent with Sparrow (http://www.sparrowmailapp.com)

Update on Brian's Condition
by Michael Collins 31 Jan '12

31 Jan '12

Hey all, Brian says that the latest is as follows: The lump in his chest is actually a lymph node. They are running further tests to see if they can track down what's going with it. The mass in his left lung appears just to be an infection, but again they are running more tests to make sure. Please everyone keep Brian in your thoughts and prayers. Thanks! -Michael

msrp support
by Seven Du 31 Jan '12

31 Jan '12

Hi, We are working on msrp support in FS. With the following patch to lib sofia, the msrp SDP can deliver to mod_sofia http://pastebin.freeswitch.org/17944 questions: 1) should I submit this to our jira or to the the sofia team? Any suggestions on the patch? 2) As FS is a B2BUA, so I think it would be endpoint-to-endpoint bridge, then we need start TCP/MSRP thread to handle media a. It should more like video handling or more like fax ? That means to hack bridge code to also handle msrp, or should we implement api like tx_fax/rx_fax vs tx_msrp/rxmsrp? b. for text over msrp, is it possible to routing the chatplan like mod_sms c. the first stage would be just endpoint to endpoint, shoud we implement relay ? or even switch mode for conference? I'm very new to msrp. 3) we found a msrp lib from http://confiance.sourceforge.net/ . It's GPL, I know it's not license compatible, but as I learned from previous talk about video, the code can put elsewhere and we just implement the logic to hook them on. Or other lib we could use? Any suggestion is appreciated. Seven. -- About: http://about.me/dujinfang Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn Sent with Sparrow (http://www.sparrowmailapp.com)

UPDATE: Donating To Assist Brian West
by Michael Collins 30 Jan '12

30 Jan '12

Good news, We've contacted PayPal and made sure that they are aware of the fact that Brian may be receive a number of donations. Sometimes this can be construed as "suspicious activity" so it's good to be prepared. PayPal has requested that we use payment type "Personal" and that the money is being sent as a "gift." Here's a quick screenshot: Let's all give Brian some PayPal love! Thanks, Michael P.S. - If you have any questions please email me off list.

Re: [Freeswitch-dev] ftdm_call_place and caller_data.call_id

Hi, Thank you. > > > Hi, >> >> >> You are better off using mod_freetdm.c as the reference, the sample/test > applications may be outdated. > > Unfortunatelly in mod_freetdm.c there seems to be no need for the call_id from the ftdm_call_place_ex(..). > ftdm_channel_t is an opaque type to API users.

I've recently tested head from freeswitch git, but the caller_data.call_id is still zero after returning from ftdm_call_place_ex(). My problem is that the comment aroung _ftdm_call_place() in the freetdm api says: * \note When this function returns FTDM_SUCCESS, the member .fchan from caller_data will be set to the channel used to place the call * and .call_id to the generated call id for that call * but my applciation still receives zero. mod_freetdm seems to not care about this call_id at all. So my workaround is stil following: ftdmret = ftdm_call_place_ex(&caller_data, &hunting, usrmsg); if (ftdmret == FTDM_SUCCESS) { callerData = ftdm_channel_get_caller_data(caller_data.fchan); freetdmLibCallId = FtdmCallId(callerData->call_id); } and that was the trigger to my post. Please, is the comment from the freetdm.h about the call_id within the caller_data valid? Is the zero also valid call_id? Thank you in advance Juraj

Hi everybody I have a small problem from the dial plan. I want to bill calls made by softphones. when I do a curl lookup from the dialplan, I can not find any value in ${curl_response_data}. Testing in the cli returns correct value, so it looks correct. <action application="curl" data="data= http://208.117.44.59/LCR/xxxxxxx.aspx?lega=xxxxx&legb=xxxxxx" /> <action application="export" data="nolocal:nibble_rate=${*curl_response_data *}" /> Any suggestions? regds Inge

Community Alert: Our Friend Brian West Is In The Hospital
by Michael Collins 30 Jan '12

30 Jan '12

Hello FreeSWITCH Community, We wanted to let everyone know that Brian West is in St. Francis Hospital, Tulsa, OK. He is checked into room 4325. At this point it looks like he will be there for at least a week. I think it's safe to say that Brian is a dynamo not just for FreeSWITCH but for open source VoIP and telephony. My guess is that there's not a person who's worked with Asterisk or FreeSWITCH in the past 10 years who hasn't been aided in one way or another by Brian. Personally I can say that in the past five years Brian has helped me immeasurably. I think I have literally asked him thousands of questions and he has patiently answered them all. We would like to have everyone keep Brian in their thoughts and prayers. Please feel free to send him cards and well wishes at the hospital. Also, if you wish to send gifts and such to his home address you may do so: Brian West 714 Osage Ave McAlester, OK 74501-6638 For those who are interested in helping in more practical ways, such as helping to defray the considerable medical costs that no doubt will be incurred, we will have more information shortly. Please spread the word via Facebook, Twitter, and any other medium you have. Let's all let Brian know just how much we value him as a colleague and friend! -Michael Collins
