[Freeswitch-dev] New FS sounds testing
by Michael Collins 30 Dec '10

30 Dec '10

FreeSWITCHers, We have the new sounds rolled and I'd like to do some expanded testing before I update in git. If anyone wants to get the latest sounds then go to your src directory and edit build/sounds_version.txt. Change en-us-callie from 1.0.13 to 1.0.14 and then do "make cd-sounds-install". The latest sounds should get installed. Please try this on your non-production systems first! :) Please reply to me off-list and let me know if you run into any problems or if the sounds are okay. I would like feedback either way. If we don't have any issues then I'll bump the sounds version in git and everyone will be good to go. Thanks! -Michael P.S. - If you would like to review which sound prompts are new to 1.0.14 then check this commit: http://fisheye.freeswitch.org/browse/freeswitch.git/docs/phrase/phrase_en.x…

[Freeswitch-dev] mod_conference tracking
by João Mesquita 28 Dec '10

28 Dec '10

Hello you all. I hope you are all having a good holiday. I have been looking for the best way of tracking conference usage for reporting purposes (basically answering the question: what happened and when on conference nº X?) and I thought of the following alternatives that I would like to discuss with you. 1. Using ESL and the CUSTOM events to keep track of what happened when (I guess that's the most widely used) 2. Creating a new entry on switch_caller_profile, that would be filled by the mod_conference module anytime something changes on the conference. Something similar to what the origination_caller_profile does but that would be manipulated by the mod_conference. This option could neatly integrate with the xml cdrs but would mess a little more on the core. Not sure it is desirable. 3. Make mod_conference spit it's own XML for each conference created so that we know what happens and can link offline to other cdr entities. Or, maybe I am completely dumb and trying to do something that it is not supposed to be done or forgetting some resource that is already available. João Mesquita

[Freeswitch-dev] Query related to enabling SRTP in FreeSWITCH-1.0.7
by Goutham BG 20 Dec '10

20 Dec '10

Hi, I have been trying to enable SRTP in FreeSWITCH-1.0.7 and have been facing some issues. I have the following entry in my dialplan XML file: *<extension name="IVR"> <condition field="destination_number" expression="^IVR$"> <action application="bridge" data="loopback/app=socket: 47.152.232.156:8084 async full"/> </condition </extension>* A SIP phone (Avaya 12XX) configured in "SRTP best effort" mode dials into this extension and is connected to the IVR. But the media is established in SRTP in one way and RTP in the other way. The phone offers the following SDP in the INVITE message: v=0 o=- 10170 10170 IN IP4 47.152.232.147 s=Sip Call c=IN IP4 47.152.232.147 t=0 0 m=audio 5016 RTP/AVP 0 8 18 101 102 a=rtpmap:0 PCMU/8000 a=ptime:20 a=rtpmap:8 PCMA/8000 a=ptime:20 a=rtpmap:18 G729/8000 a=ptime:20 a=fmtp:18 annexb=no a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=rtpmap:102 X-nt-inforeq/8000 a=sendrecv m=audio 5016 RTP/SAVP 0 8 18 101 102 a=rtpmap:0 PCMU/8000 a=ptime:20 a=rtpmap:8 PCMA/8000 a=ptime:20 a=rtpmap:18 G729/8000 a=ptime:20 a=fmtp:18 annexb=no a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=rtpmap:102 X-nt-inforeq/8000 a=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:Tjivoci1I/mVkt/Fq/ZsiY+ +ornJoXjZ5tSadho4 a=sendrecv As we can see, there are two "m=" lines in the SDP of the offer; one for RTP and another for SRTP. FreeSWITCH-1.0.7 answers the call by sending 200OK with the following SDP: v=0 o=FreeSWITCH 1291628984 1291628985 IN IP4 47.152.232.156 s=FreeSWITCH c=IN IP4 47.152.232.156 t=0 0 m=audio 11280 RTP/AVP 0 101 a=rtpmap:0 PCMU/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 m=audio 0 RTP/SAVP 19 As you can see above, FreeSWITCH accepts the RTP stream and rejects the SRTP stream (by sending port as 0) in the SDP. The SIP phone sends the media in RTP(which is expected). But, FreeSWITCH sends the media in SRTP to the SIP phone. I believe this is a bug in FreeSWITCH as it is supposed to send the media in RTP since it accepted RTP in the answer (200OK). *Query: ======* In order to make FreeSWITCH select SRTP in the SDP of the answer(200OK), I made the following change(in *bold*) in FS dial plan: *<extension name="IVR"> <condition field="destination_number" expression="^IVR$"> <action application="set" data="sip_secure_media=true"/> <action application="bridge" data="loopback/app=socket: 47.152.232.156:8084 async full"/> </condition </extension>* In FreeSWITCH-1.0.6(before updating to 1.0.7), this worked and FS accepted the SRTP stream and rejected RTP in the answer(200 OK) as shown below: m=audio 0 RTP/AVP 19 m=audio 12084 RTP/SAVP 0 101 a=rtpmap:0 PCMU/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 a=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:hgv7ClqDx1irTRrXq2NEm9Gbouw0969bBU3n+LcM But after updating the FreeSWITCH-1.0.6 to 1.0.7, the above mentioned dial plan change (i.e, setting sip_secure_media=true) is not working. It is still behaving in the same way as it did without the XML change. Can you please let me know if anything else needs to be added in dialplan XML file for enabling SRTP in this case in FreeSWITCH-1.0.7 or am I missing something here? I have referred the following FS wiki pages for making the SRTP changes: http://wiki.freeswitch.org/wiki/Secure_RTP http://wiki.freeswitch.org/wiki/SRTP Note: There is no issue when the SIP phone is configured in "SRTP only" mode where only SRTP stream is offered in the SDP of the INVITE. In this case, SIP phone and FreeSWITCH communicate properly using SRTP. This doesn't require setting "sip_secure_media=true" in the dialplan XML file. P.S: I am a newbie to FreeSWITCH. So, please forgive me if I am asking basic questions. Thanks Goutham B G

[Freeswitch-dev] Freeswitch & Solaris 10
by Marty Lee 20 Dec '10

20 Dec '10

Hi, just playing with building FreeSwitch on a Solaris 10 box and am hitting a link error when building the target '.libs/freeswitch' Undefined first referenced symbol in file make_mask32 freeswitch-switch.o ld: fatal: Symbol referencing errors. No output written to .libs/freeswitch Looking at the source, make_mask32 seems to be defined in the spandsp/src/bit_operations.c file, which isn't involved in the linking at this point. Building with Sun Studio 12, just in case it's of any interest. I'll try and move the make_mask32 function in to the library and see if that cures the problem. Thought I'd ask here, as this kind of thing should appear on most platforms if it really is a problem - meaning it might be something at my end. m ----- Marty Lee e: marty(a)maui-systems.co.uk Technical Director v: +44 845 869 2661 Maui Systems Ltd f: +44 871 433 8922 Scotland, UK w: http://www.maui-systems.co.uk
