------

[10:05] <ivelin> let's get started
[10:06] <ivelin> #1 JSLEE
[10:07] <ivelin> Eduardo?
[10:07] <@alexandrem> mart1ns said he couldn't make it to the chat
[10:07] <@alexandrem> but that he also had no updates on JSLEE this week
[10:07] <ivelin> ok
[10:07] <ivelin> #2 Diameter
[10:08] <@alexandrem> wrt Diameter, we've started to work on TLS
[10:09] <@alexandrem> resume the work already done, test it against other diameter stacks
[10:10] <ivelin> TLS is done?
[10:10] <@alexandrem> we will also start moving the content that existed on mobicents.org related to diameter to diameter project homepage
[10:11] <@alexandrem> we have experimental support, since 1.4.0.FINAL but it's not clear how it should work
[10:11] <ivelin> lol
[10:11] <ivelin> why is it not clear? Which part is not standardized?
[10:11] <@alexandrem> even from RFC, a new version of diameter base suggests a different way than original
[10:11] <jean> can we prioritize SCTP first ?
[10:11] <jean> and wait for the specs to settle down ?
[10:12] <@alexandrem> well some use plaintext capability notification prior to using ssl connection, others use ssl from the beginning
[10:12] <@alexandrem> capability negotiation
[10:12] <@alexandrem> not notification :)
[10:13] <ivelin> I see. Which stacks are you testing against?
[10:13] <@alexandrem> ivelin: at the moment, seagull, ericsson and will try with freeDiameter
[10:14] <@alexandrem> jean: we can prioritize it, but TLS is almost done.. trying a last stretch to have it working properly
[10:14] == vinu [7aaea636@gateway/web/freenode/ip.122.174.166.54] has joined #mobicents
[10:15] <jean> I see what is the ETA for completion ?
[10:15] <@alexandrem> jean: I'd say 2-3 days
[10:16] <@alexandrem> maybe over the weekend we'll be able to get it right
[10:16] <@alexandrem> will update after the weekend with progresses
[10:16] <ivelin> cool
[10:16] <ivelin> how about the switch to NIO?
[10:17] == charles_r [c9c1fa7a@gateway/web/freenode/ip.201.193.250.122] has joined #mobicents
[10:18] <@alexandrem> ivelin: we can evaluate that later, we rather have it working as we are very close and then evaluate options with more time
[10:19] <ivelin> ok
[10:20] <ivelin> so TLS is the goal for this week
[10:20] <ivelin> anything else on Diameter?
[10:20] <@alexandrem> yeah, it is
[10:20] <ivelin> cool. thx
[10:20] <@alexandrem> that's all.
[10:20] <ivelin> #3 SS7
[10:21] <ivelin> Sergey, can you cover this topic?
[10:22] <abhayani> OK so we are hitting long delayed issue now
[10:22] <abhayani> SLS based loadsharing
[10:22] <abhayani> this was missing for quite some time now
[10:22] <abhayani> and hits all layers SCCP, M3UA, MTP
[10:23] <abhayani> we have identified some algo we can use that will work for all layers
[10:23] <abhayani> The other announcement is we have new project GMLC
[10:23] <abhayani> http://code.google.com/p/gmlc/
[10:23] <abhayani> I have the code base locally where it takes HTTP Post request with msisdn
[10:24] <abhayani> and finds out the cell if for this msisdn and sends back response
[10:24] <ivelin> GMLC is to help locate a mobile device given its ID?
[10:24] <abhayani> right
[10:25] <abhayani> code is still changing too much so nothing committed
[10:25] <abhayani> but by next week we should have some preview ready
[10:26] <abhayani> @baranowb, svetyutnev ?
[10:26] <ivelin> what's the use of SLS load sharing?
[10:26] <abhayani> its by protocol definition
[10:26] <abhayani> defines how the load is shared between Linksets and Links
[10:27] <abhayani> and on SCCP layer defines how load is shared between multiple apps
[10:27] <svetyutnev> I committed an update for MAP - several messages were added of updated. Update was made according to live traces (something was missed in implementation)
[10:29] <abhayani> thats it from SS7
[10:30] <ivelin> Bartek, no update?
[10:30] == tommyq [~tho...@c-50-143-66-229.hsd1.fl.comcast.net] has joined #mobicents
[10:31] <ivelin> #4 Restcomm
[10:32] <tommyq> Okay we are doing great on timing for our release dates. I have been a bit wrapped up with a customer but I will update the roadmap all the way through to FINAL
[10:32] <tommyq> George is kicking all that ass when it comes to automated testing
[10:32] <tommyq> and I haven't had a chance to wrap up docs effort but i will do it as soon as I wrap up with my current's customers tasks
[10:33] <tommyq> Other than that we are doing a code freeze for the community edition in the first week of November and only focus on tests and doc
[10:33] <tommyq> s
[10:35] <tommyq> George my friend would you like to add
[10:35] <tommyq> oh yeah one more thing
[10:35] <tommyq> Charles wrote a great intro to RestComm @ http://telestax.com/2012/10/24/getting-started-with-restcomm/
[10:35] <tommyq> Thank you for the great work Charles!
[10:35] <gvag> as we said yesterday, i have embedded media server extension ready, thanks to Julian to provide the required
[10:35] <gvag> tools from MMS
[10:36] <gvag> and i am working on testsuite of Restcomm
[10:36] <charles_r> con gusto
[10:36] <gvag> thats from my side
[10:36] <tommyq> @charles_r :)
[10:37] <ivelin> so Beta 2 is expected when?
[10:38] <tommyq> first week of November
[10:38] <tommyq> as per the roadmap
[10:38] <tommyq> I just need to update the rest of the dates :)
[10:40] <ivelin> that's next week
[10:40] <tommyq> ;)
[10:40] <tommyq> just waiting on my docs
[10:40] <ivelin> ok, fingers crossed
[10:40] <tommyq> no need my frien
[10:40] <tommyq> d
[10:40] <tommyq> there is nothing stopping the release
[10:40] <tommyq> :)
[10:40] <ivelin> no lack of confidence :)
[10:40] <tommyq> lol, NEVER!
[10:43] <ivelin> lol
[10:43] <ivelin> #5 SIP Servlets

[10:46] <ivelin> are there any interesting community comments yet on the webrtc demo?
[10:46] <jean> there is comments
[10:46] <jean> but no feedback on testing yet
[10:47] <jean> https://www.facebook.com/groups/mobicents/permalink/525193767494861/
[10:48] <ivelin> #7 Productization
[10:48] <ivelin> Pavel?
[10:48] <jean> https://groups.google.com/d/topic/mobicents-public/-7oTUd1E22w/discussion
[10:48] <yulian_o> what about 6?
[10:49] <ivelin> I need my glasses
[10:49] <ivelin> #6 Media Server
[10:50] <yulian_o> final release is delayed a bit , since usage has been grown and some issues are arising. resolved several problem with id generations for mgcp
[10:50] <yulian_o> currently waiting for perfomance tests results from community user : https://groups.google.com/forum/?fromgroups=#!topic/mobicents-public/XKc2PqUyDd8
[10:51] <yulian_o> have annoying ULAW/ALAW problem when file is not well formated ( ticking )
[10:51] <yulian_o> want also check mgcp parsing , since several problems may be arised there in specific cases
[10:51] <yulian_o> and of course docs
[10:51] <yulian_o> thats currently
[10:54] <ivelin> final for 3.0?
[10:54] <yulian_o> yes
[10:54] <yulian_o> 3.0.0 actually
[10:55] <ivelin> ok
[10:55] <ivelin> fast progress on a major release
[10:56] <yulian_o> yes hope also perfomance will be great so it will make it easier to move forward
[10:56] <ivelin> plans for next release?
[10:57] <yulian_o> there are 4 blocks : perfomance , more codec+ fax , video , and management
[10:57] <yulian_o> i thought video will be last one , but currently i got request from client to implement it , so i can not know .
[10:58] <yulian_o> its either codecs or video progress
[10:58] <ivelin> what kind of video? playback, mixing, transcoding?
[10:59] <yulian_o> initially there will be one codec support , playback , conference. ss7 support should be added and may be recording
[11:01] <jean> which codec by the way ?
[11:01] <yulian_o> didnt decided yet
[11:01] <yulian_o> may be H.2645
[11:01] <yulian_o> H.264
[11:01] <jean> ok
[11:02] <jean> there is a codec war in WebRTC going on
[11:02] <jean> h.264 vs VP8
[11:02] <tommyq> If you can VP8 or WebM
[11:02] <tommyq> is open
[11:02] <jean> H264 is open as well under a certain threshold
[11:02] <jean> apparently
[11:02] <tommyq> and seems to have very good documentation for implementors
[11:02] <tommyq> oh okay I was unaware
[11:03] <jean> http://tools.ietf.org/html/draft-dbenham-webrtc-videomti-00
[11:03] <jean> look page 7
[11:03] <ivelin> doesn't h264 take optimized native code and sucks in a full CPU ?
[11:04] == baranowb [~bara...@213.108.152.183] has quit [Ping timeout: 244 seconds]
[11:04] <tommyq> @jean that is a bit tricky that language they are using
[11:04] <yulian_o> what is >100KU?
[11:06] <jean> channels I guess
[11:08] <yulian_o> so its free up to 100 thouhand of channels?
[11:08] <jean> yeah tat's my understanding 100K channels a year
[11:09] <tommyq> again ambiguous
[11:10] <tommyq> royalties are high for H.264 and you don't get anything VP8 doesn't give you
[11:10] <ivelin_> either codec would be a big challenge
[11:10] <jean> I'm not in favor of any
[11:10] <ivelin_> technical
[11:11] <tommyq> I think VP8 would be easier from a legal and implementation point of view
[11:11] <tommyq> my opinion obviousl
[11:11] <jean> just the better one to interoprate with or widely adopted
[11:11] <tommyq> y
[11:11] <jean> for easier and higher penetration
[11:11] <tommyq> check out the webm rfc
[11:11] <ivelin_> its unclear how interoperable vp8 is becuase there aren't a lot of different implementations
[11:11] <tommyq> it's quite clear how to implemen
[11:11] <tommyq> flash
[11:11] <ivelin_> there is one open source one that is just now gaining traction in some of the browsers
[11:11] <tommyq> adobe flash started with and still supports
[11:12] <tommyq> google chrome
[11:12] == ivelin [adac46b2@gateway/web/freenode/ip.173.172.70.178] has quit [Ping timeout: 245 seconds]
[11:12] <ivelin_> all in demo mode, except skype
[11:12] == yulian_o [51dac2ab@gateway/web/freenode/ip.81.218.194.171] has quit [Ping timeout: 245 seconds]
[11:12] <ivelin_> anyways, video is a long topic.
[11:12] == svetyutnev [4e6b0690@gateway/web/freenode/ip.78.107.6.144] has quit [Ping timeout: 245 seconds]
[11:13] <ivelin_> let's move on
[11:13] <ivelin_> #8 Docs
[11:13] <ivelin_> Charles still on?
[11:13] == vinu [7aaea636@gateway/web/freenode/ip.122.174.166.54] has quit [Ping timeout: 245 seconds]
[11:13] <charles_r> yes
[11:13] == abhayani [29ce0101@gateway/web/freenode/ip.41.206.1.1] has quit [Ping timeout: 245 seconds]
[11:14] <charles_r> worked with thomas to test restcomm
[11:14] <charles_r> will finalize this week and update the online doc with relevant info
[11:15] <charles_r> Yulian_o_ needs to send draft doc for media server
[11:15] <charles_r> so that I can start building a similar intro page to restcomm
[11:15] <yulian_o_> yes i will do that as as i will finish with bugs , sorry
[11:15] <ivelin_> Yulian, when do you think you can have a draft for Charles?
[11:17] <ivelin_> Charles, what are the next week deliverables for docs?
[11:17] <charles_r> the idea is to standardized the product introduction docs so that users can quickly see the potential and interact with telestax
[11:18] == svetyutnev [4e6b0690@gateway/web/freenode/ip.78.107.6.144] has joined #mobicents
[11:18] <ivelin_> good idea
[11:19] <charles_r> I will be contacting product owners offline with request for information
[11:19] <charles_r> jean will also give me input about WebRTc
[11:19] <yulian_o_> hope i will have enough time in weekend to finish it
[11:19] <charles_r> that is it and the rest will be offline
[11:20] <ivelin_> ok, sounds good
[11:20] <ivelin_> anything else guys?
[11:21] <ivelin_> let's wrap up the meeting
[11:21] <ivelin_> thanks everyone for joining

[Bartosz Baranowski]

Sorry guys. Ive warned JD that Im having my neighborhood meeting.

Soo in short. Cutting through USSD/SMSC issues. Last week was just a warm up with some trivial USSD issue. This week Im going to work on USSD push and SMSC persistance and scheduler.
