[Freeswitch-dev] very early prototype of SLA/BLA
See http://jira.freeswitch.org/browse/MODENDP-179 for how far I've gotten on doing SLA/BLA in the draft-anil-sipping-bla-02/03 style. If the patch is applied and the feature enabled and Polycom phones in use and the phones configured for type="shared" and thirdPartyName="<some extension>", the lights really work. And with a patch Anthony provided to me today to add support for INVITE w/REPLACES, you can even put a call on hold at one phone, go to another phone with a blinking light for that line, and pick it up. (But you can't pick up a second phone with the first still on the call and have them both join the call at the same time via an auto-created conference... yet) Amazing how much work it takes to emulate an old key system. Again, this is a total rough-draft hack of a prototype, just enough to get the lights working, and with at least one major memory leak and/or nua handle leak(s) that cause bad things to happen, so isn't for production at all yet. I will be continuing to work on it myself, but I know this is something that gets requests so I wanted to get the fact that I'm working on it out in the open ASAP. Matthew Kaufman

See http://jira.freeswitch.org/browse/MODENDP-179 ... Of course right after uploading that, I realized I hadn't copied over my fixes for the two hardcoded contact strings. There are two places that say SIPTAG_CONTACT_STR("<sla-agent@198.202.199.1>") where it should actually be dynamically generated from the profile's identity rather than my hardcoded IP address.
However, jira.freeswitch.org isn't responding *and* I'm headed to bed now and going to my real job all day tomorrow, so if you try to play with this before I get an update in later this week, you'll run into this problem. Matthew Kaufman

I still see a compelling business case for a foundation supported free open source set of libs for the base protocols, commercially supported by multiple contributors who build higher level applications using the base protocols. In a situation like this, commercial sponsors can pool resources for certification. Obviously anyone using a modified version would not be using certified code but the sponsors who pay for certification would still get multiple benefits.

Some people like to donate code to open source. Thanks again Jan for the ISDN code. We are still working on it and some day we should make it to SS7 but it will probably take a bit more work since we are already short on hands for people who want to work on OpenZAP abstraction layer.

Hi, I'm currently working on ISDN (E1/T1/BRI) support, D-channel protocol wise and hardware wise in connection to FreeSwitch. I'm also adding support for analog phone adapters through the same API. I promised to Mike Jerris several times I would do something, but then the time ran away ... This week I put down several hours integrating the ISDN support in FreeSwitch with the ISDN support in ISDN4BSD, which should end up with a unified BSD-licensed OpenZap code base. If you are interested in giving some feedback you can check out the following files: svn --username anonsvn --password anonsvn \ checkout svn://svn.turbocat.net/i4b/trunk/openzap.hps The files that are there are mainly for inter-process communication, and have been constructed in a way that allows easy porting to other platforms. In general sockets can be used for this on other UNIX compatible systems as a fallback mechanism where the optimised kernel mechanism is not present. The core (FreeBSD kernel module): Handles routing and broadcasting. The client (FreeBSD library): Dumb node sending and receiving messages. What I plan next is to implement a set of nodes, like [ISDN] controller- Q921- and Q931- node. Nodes have pre-defined address ranges which they are listening to. Hence I already have a DSS1 stack, splitting it up into using message based communication should not be a very big task. Then you have the application, like FreeSwitch being a node aswell picking up broadcast events, which are mostly incoming calls from Q931 and making outgoing calls. Messages have been split into two categories: Important-frames and Unimportant-frames. I-Frames gets to use 64 queue entries before getting dropped. U-Frames gets to use only 32 queue entries before getting dropped. These numbers have not been tuned yet. Also I have thought through message timing. In bigger systems I see that it is required to dither messages in time. On cannot simply receive 30x400 bytes on an E1 and burst it into the system, because the message queues will overflow pretty quickly. Instead the interrupt rate of the hardware needs to be increased so that 400 bytes are received in "1/30 * interval" fashion. This will generally improve the system and load-balance in time. The generic Message Header looks like this: /* NOTE: All fields are little endian */ struct zap_hdr { uint8_t dwDstNode[4]; /* Destination Node */ uint8_t dwSrcNode[4]; /* Source Node */ uint8_t wCommand[2]; /* Command Number */ uint8_t wMsgNum[2]; /* Message Number */ uint8_t bReserved[4]; /* Reserved bytes */ }; If you have access to ISDN testing equipment and would like to help test the non-EuroISDN variants of my upcoming ISDN implementation, please let me know. I expect to have something up and running within the next month, hopefully not running out of time this time :-) --HPS

Hi Jan, It is a set of system calls or IOCTLs used to transfer messages between the kernel and userland application. Currently copyin/copyout is used, and only one message is transferred at a time, though the possibility is there to change it. What I want to acchieve is to reduce the number of system calls needed if there are multiple messages to be received or transmitted at a time, by transferring multiple messages in a single syscall. When using read()/write() on a socket this is not possible. You get all the data back to back in one buffer, instead of in separate buffers that can be separately freed. --HPS
hi Hans, The standard for a PABX on G.711 is 6ms packaging of data - this is 48 byte per channel. If you go higher than this you start getting to much latency, if you go lower than this you start using to much CPU. 400 byte is 50ms, meaning we have spent a lot of the latency budget already here, but this shoud be run-time configurable per channel as per need. - G.711 6 ms - IVR is 250 ms - 729 10 ms - 723 30 ms etc. You need to take into consideration that you are on a system with 8, 16 or 32 E1's of whick some is running IVR, others SIP, others swicthing back out on a different E1 etc. Jan

That is one of the benefits of sangoma hardware. They have an mtu value in the driver you can set to 80 (10ms) which despite the interval the channel is using it will operate at 10ms interrupts.

Another useful advantage without the latency tradeoff is to read a full span or card every 1ms (or whatever sane interval) and chop up the bytes in userland. The latency argument dies if you are bridging to voip, so if you can handle bridging the tdm to tdm channels in kernel space, you could easily get away with 10ms reads to user space as well.

I would do this very differently. They key to performance is to reduce memcpy and malloc to a minimum. 1. You feed a page from PCI card and swap this over on interrupt/timer - and at this point you copy data to channel buffer or directly to next B channel. The channel buffers can be shared OS memory, meaning that you write from the PCI card in one end and read (directly from buffer) from app in the other end. Also create the channel buffer as a sircular list of packets and you have no malloc involved. You can also use this for messaging between threads and even apps - it is a well known and extremely fast technique. also let the IPC fall back to IP and you could start spreading FreeSWITCH modules across a network. I have some code somewher that does this so I can set up a demo once I return in a weeks time.

That’s the same thing we saw... Everyone wants SS7 but no one wants to help fund it... And to make matters worse just getting proper documentation for ANSI SS7 is not exactly a cheap endeavor. Unfortunately telecordia and crew still want to charge thousands of dollars for the docs when the ITU decided ages ago to make those available for free... Even then its still a substantial amount of effort to get something working (even if you have active links you can use to help understand whats going on)

I still see a compelling business case for a foundation supported free open source set of libs for the base protocols, commercially supported by multiple contributors who build higher level applications using the base protocols. In a situation like this, commercial sponsors can pool resources for certification. Obviously anyone using a modified version would not be using certified code but the sponsors who pay for certification would still get multiple benefits.

I've done some SS7 development in the past, using dedicated TX3220 and TX4000 signalling boards from NMS Communications (recentlty aquired by Dialogic). Even with a lot of commercial documentation available, it's horribly complex stuff, especially redundancy. And you need another SS7 switch to test against for interoperability. And SIP trunks are becoming more and more commonly available these days, so one can question if it's worth the effort. Still, I would really like it if someone would try and develop such a feature. Off-topic: If you need SS7 and are willing to pay for it, I can recommend audiocodes mediant gateways. There's a model available with embedded SS7 signalling, provided by Teles.

Trust me AT&T doesn't have free docs. There are hundreds of ANSI SS7 docs and they put alot of work and money to make sure you can't get them via google search. Much of it is not in ITU but many ITU switch support ANSI features such as Class 5. Even with the ITU docs in hand you'll need a large team to get it complete enough for Class 4/5 operations anytime soon. On Jan 28, 2009, at 2:42 PM, Jan Berger wrote:

Here in the states they want you to pay for documentation on cable pinouts and don't even think about getting documentation for something
like TCAP LIDB without giving up your first born and an arm.

That's the same thing we saw... Everyone wants SS7 but no one wants to help fund it... And to make matters worse just getting proper documentation for ANSI SS7 is not exactly a cheap endeavor. Unfortunately telecordia and crew still want to charge thousands of dollars for the docs when the ITU decided ages ago to make those available for free... Even then its still a substantial amount of effort to get something working (even if you have active links you can
use to help understand whats going on)

I still see a compelling business case for a foundation supported free
open source set of libs for the base protocols, commercially supported
by multiple contributors who build higher level applications using the
base protocols. In a situation like this, commercial sponsors can pool resources for certification. Obviously anyone using a modified version would not be using certified code but the sponsors who pay for
certification would still get multiple benefits.
