| 02:03.02 | zelele | Hi for everybody. There is a long time that I used IRC, that I almost forgot how to use this. hahaha |
| 02:04.33 | zelele | I would like to ask If somebody already faced an Asterisk scalability problem with huge number of IP endpoints. |
| 02:05.25 | zelele | I have a scenario with about 18500 IP Telephonies that I need to migrate to Asterisk solution. |
| 02:07.10 | zelele | I would like to spread these 18500 endpoints over some Asterisk servers, because of load and High Availability requests. |
| 02:08.14 | zelele | But when Bob IP Phones register on server A, and Alice IP Phones register on server B, how they can call each other ? How the will know where the other will be registered ? |
| 02:09.03 | zelele | I already saw Dundi project, but it seems a little "dead" and It is not prepared to use PJSIP. |
| 02:09.14 | zelele | So... How to achieve this ? |
| 02:10.04 | zelele | Does anybody has some clue and would like to share some thoughts ? |
| 02:10.41 | zelele | I will really appreciate your comments. |

| 02:56.08 | lagzilla | I would guess using an SBC http://www.kamailio.org/dokuwiki/doku.php/asterisk:load-balancing-and-ha |
| 02:57.00 | lagzilla | We have a shared database between servers so that is also an option for you |
| 03:02.27 | zelele | Shared database ? Are you talking about something like Asterisk Realtime Database ? |
| 03:24.17 | [TK]D-Fender | zelele> But when Bob IP Phones register on server A, and Alice IP Phones register on server B, how they can call each other ? How the will know where the other will be registered ? <- that's up to your dialplan |
| 03:24.21 | [TK]D-Fender | Phones don't know anything |
| 03:24.36 | [TK]D-Fender | they send calls to the server they are configured to send them to. |
| 03:24.48 | [TK]D-Fender | And it's up the the call processing to determine what to do with that |
| 03:28.01 | *** join/#asterisk jwpierce3 (jwpierce3@001.srv.trnkmstr.com) |
| 03:29.42 | zelele | That is exactly that I would like to know. As I mentioned before, I have 18500 IP Phones that I would like split over some asterisk server (let's say 10 servers). How the dialplan will check where that IP Phone will be registered ? |
| 03:30.51 | [TK]D-Fender | That depends on how you intend to lay your setup like |
| 03:31.19 | [TK]D-Fender | Including if you expecta particular device to connect to a specific server |
| 03:32.00 | zelele | If Bob register on server A, and another moment Alice IP Phone register on server F, for example. I wouldn't like to ask for server A to send requests to server B, C, D and E before to find that Alice's Phone is registered on server F. |
| 03:33.46 | [TK]D-Fender | The simplest "native" method would be to use regexten on you r peer (chan_sip option, unsure if it's also in pjsip), and DUNDi. |
| 03:33.48 | zelele | What I'm asking if there is some way to check directly on some database where Alice's phone is registered, and send a request directly to that server. |
| 03:34.30 | [TK]D-Fender | Depends how that database gets populated. That's the huge catch |
| 03:34.59 | [TK]D-Fender | DUNDI is a way around thatas I've described |
| 03:35.42 | zelele | I read about DUNDi, but It seems that It is not prepared to work with PJSIP. |
| 03:36.03 | zelele | There isn't a LOOKUP tool inside Dundi with PJSIP. |
| 03:36.29 | [TK]D-Fender | DUNDI isn't supposed to care about protocol |
| 03:36.39 | [TK]D-Fender | you don't lookup "sip". It looks up EXTENSIONS |
| 03:37.36 | zelele | Understood. |
| 03:38.11 | zelele | I will give another chance to Dundi... |
| 03:39.07 | zelele | Thanks D-Fender. |

| 19:42.54 | shimshon10 | i need a help |
| 19:43.40 | shimshon10 | when i reload, i have message "lconfig.c: Line 239 too long, skipping." |
| 19:43.55 | shimshon10 | how can i change the setting that i can use long lines? |
| 19:47.10 | [TK]D-Fender | show the full area around that message |
| 19:48.05 | [TK]D-Fender | And given how many places identically typed field s are used I'm sure this is no small matter... |
| 19:48.19 | [TK]D-Fender | You should reconsider whatever you're attempting to do there... |
| 19:49.15 | shimshon10 | it's a long line |
| 19:49.54 | shimshon10 | and it's limit of the langth |
| 19:51.20 | shimshon10 | it's lines that the length it's more then 256 charters |
| 19:51.37 | shimshon10 | and i have meny lines like that |
| 19:51.52 | [TK]D-Fender | You're looking at a whole pile of code mods you'll need to make & maintain... |
| 19:52.24 | [TK]D-Fender | <[TK]D-Fender> You should reconsider whatever you're attempting to do there... |
| 19:53.55 | shimshon10 | i can't change the setting that i can use a long lines? |
| 19:54.25 | [TK]D-Fender | it isn't a "setting" |
| 19:54.28 | [TK]D-Fender | it's code |
| 19:54.58 | [TK]D-Fender | code used all over the place and populated from other fields of the same length that all has to get modded to support |
| 19:56.29 | shimshon10 | and not other idea how to use long lines? |
| 19:56.46 | [TK]D-Fender | there is no "plan b" |
| 19:56.51 | [TK]D-Fender | code limits you |
| 19:57.06 | [TK]D-Fender | you'd have to modify a ton and compile it all and then maintain this as you upgrade |
| 19:57.42 | [TK]D-Fender | So you'd be advised to reconsider your approach to whatever you're doing that is hitting that limit |
| 19:58.32 | lagzilla | Could he do exten => foo; same => bar;? |
| 19:59.25 | shimshon10 | I try to use system and send log command |
| 19:59.29 | shimshon10 | long |
| 20:00.06 | [TK]D-Fender | Time to break it up and use a different method |
| 20:03.40 | seanbright | are you compiling with LOW_MEMORY enabled? |
| 20:03.55 | seanbright | if not, the line limit should be 8192 characters, which is a really long line |
| 20:04.32 | [TK]D-Fender | seanbright, Did that get mainstreamed? I remember to old limits for this... |
| 20:04.35 | seanbright | about 8000 more characters than anyone actually needs |
| 20:05.10 | seanbright | https://github.com/asterisk/asterisk/blob/13/main/config.c#L2033-L2037 |
| 20:05.55 | seanbright | shimshon10: you have lines longer than 8192 characters? what version of asterisk are you running? |
| 20:06.45 | shimshon10 | my line it's about 500 characters |
| 20:07.03 | seanbright | do you have LOW_MEMORY defined? |
| 20:07.17 | shimshon10 | yes |
| 20:07.22 | seanbright | ok |
| 20:07.29 | shimshon10 | i have LOW_MEMORY |
| 20:07.47 | seanbright | ok, i assume because you defined that you actually need it |
| 20:07.50 | shimshon10 | if i take it off it's take off the limit? |
| 20:07.54 | seanbright | yes |
| 20:08.00 | seanbright | well |
| 20:08.05 | shimshon10 | how can i take it off? |
| 20:08.06 | seanbright | it increases the limit by 16x |
| 20:08.16 | seanbright | are you compiling it yourself? |
| 20:08.49 | shimshon10 | yes |
| 20:09.24 | seanbright | run: |
| 20:09.27 | seanbright | make menuselect |
| 20:09.39 | seanbright | go to 'Compiler Flags' |
| 20:09.49 | seanbright | uncheck 'LOW_MEMORY' |
| 20:09.55 | seanbright | save & exit |
| 20:10.04 | seanbright | then run 'make' to build |
| 20:10.35 | [TK]D-Fender | Guess I'm learning something new today... |
| 20:10.55 | seanbright | i mean, LOW_MEMORY isn't set by default |
| 20:11.12 | shimshon10 | did i can take it off withot recompile? |
| 20:11.18 | seanbright | no |
| 20:19.04 | shimshon10 | thnkes, |
| 20:19.06 | shimshon10 | it's work |
| 20:19.13 | seanbright | sure thing |
| 20:19.50 | shimshon10 | and i have other question |
| 20:20.47 | shimshon10 | when i have meny calls, i have got message: |
| 20:20.54 | shimshon10 | chan_sip.c: Retransmission timeout reached on transmission |
| 20:21.11 | shimshon10 | meny times until the asterisk crash |
| 20:21.21 | seanbright | doesn't the message include a link to a wiki article? |
| 20:22.04 | seanbright | "Retransmission timeout reached on transmission %s for seqno %u (%s %s) -- See https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions" |
| 20:22.56 | shimshon10 | i see , but i dont have NAT or somtings else that block, |
| 20:23.16 | seanbright | man, you read that page really quickly |
| 20:23.43 | shimshon10 | not now, a few weks ago. |
| 20:25.05 | shimshon10 | the server it's going very slow, its take long time to go to the next line in the dial plan. |
| 20:25.24 | seanbright | how much memory do you have on your serve? |
| 20:25.26 | seanbright | server* |
| 20:25.43 | file | and are you using AGI? |
| 20:26.12 | shimshon10 | 64GB |
| 20:26.16 | shimshon10 | i use system |
| 20:27.01 | file | System would suffer the same problem, the higher the load/usage, the slower it will become |
| 20:28.06 | shimshon10 | so how can i use it for many calls? |
| 20:28.46 | file | you can't? |
| 20:29.08 | file | it's due to the way that the kernel works and how the process is executed for System (and for AGI) |
| 20:29.45 | seanbright | how many calls? |
| 20:30.03 | shimshon10 | 200 |
| 20:30.10 | shimshon10 | at the same time |
| 20:30.33 | seanbright | cores? clock speed? |
| 20:30.47 | shimshon10 | Intel(R) Xeon(R) CPU E5-1650 v4 @ 3.60GHz, 12 cores |
| 20:31.16 | seanbright | well, then system() must be the problem because you should be able to handle 200 calls with that equipment easily |
| 20:32.43 | shimshon10 | if i change it to agi it work good? |
| 20:32.51 | file | FastAGI would be fine, AGI wouldn't |
| 20:32.54 | seanbright | fastagi |
| 20:35.07 | shimshon10 | did i can use fastagi in asterisk 1.8? |
| 20:35.14 | seanbright | yes |
| 20:37.50 | shimshon10 | how i use it in the dialplan? |
| 20:37.59 | seanbright | ok |
| 20:38.15 | shimshon10 | i don't see the application fastagi |
| 20:38.21 | seanbright | it's just called AGI |
