14:47.36hlokhey when I do the hello world tutorial using linphone it tells me user busy instead of the hello world
14:47.47hlokhow do I fix it?
14:49.03SamotWell since we don't know what is wrong, we really can't say how to fix it.
14:49.46hlokokay, well I'm using the docker version of asterisk, it is version 15 point something
14:50.03hlokSamot: did the hello world thing work for your out of the box?
14:52.32hlokhttps://github.com/andrius/asterisk <-- this is the one I'm using
14:53.47fileI would highly suggest not using a Docker Asterisk until you understand Asterisk and SIP, because it adds additional complexity
14:54.49MLCOne of the SIP providers that I  am considering (Call Centric) uses round robin DNS to load balance  across their servers, and their registration expires in 60 seconds, so  it is not unusual for the server that my Asterisk registers with to  change throughout the day. This becomes a problem when there is a call  in progress and the registration changes, there is no longer any SIP  traffic through the firewall to keep the UDP port open
14:54.49MLCto the server on  which that call originated and is connected to. When the remote party  hangs up the provider sends a BYE command but the UDP port is no longer  active in the firewall and so the call in Asterisk does not terminate.  I'm looking for ideas on how to fix this.  I can increase the UDP  timeout in the firewall, but unless I make it 2+ hours long, there could  always be a call that lasts longer than that. Is there somethin
14:54.49MLCg that  would send an an occasional SIP packet of some kind on a call in  progress?
14:56.01hlokfile: hmmm, okay so I gotta do an adhoc install first?
14:56.01igcewielinglike rtpkeepalive?
14:56.35filethat would eliminate an aspect of things, SIP embeds IP addresses into things so sticking it in Docker can complicate that due to Docker networking
14:57.03MLCigcewieling I am unfamiliar with that, can you elaborate?
14:57.28hlokfile: well the ip addresses seem to be working okay, cause I am registering just fine.
14:58.09hlokalso I hear the busy tone, and ringing tone when I call it from my other SIP phone.
14:58.32fileif you provide the console output then it may show what is up
14:58.43igcewielingMLC: no, but a grep can: grep keepalive asterisk-16.3.0/configs/samples/pjsip.conf.sample
14:59.06MLCI found it: rtp_keepalive  that seems to send RTP packets. I need to send SIP packets
14:59.21hlokfile: how do I provide a console output?
14:59.22MLCthe RTP ports are staying open
14:59.36igcewielingMLC: try qualify and qualifyfreq then
14:59.47fileI don't know how you are supposed to enter that container and retrieve logs or access the Asterisk console
15:00.19MLCigcewieling: I will try, but I'm guessing that those will go to the currently registered server, not the server that is active for a given call
15:00.41igcewielingMLC: Perhaps your problem doesn't have a solution.
15:00.52MLCigcewieling: it may not
15:01.05MLCother than the provider making some changes
15:01.13igcewielingYour best bet is get rid of the external firewall.
15:01.40MLCI've considered that
15:02.03igcewielingIf nothing else, turn off SIP ALG
15:02.59igcewielingMLC: why not register by IP and use only one of their servers?
15:03.22MLCThought of that too, but the provider made it clear that was undesirable.
15:05.16hlokfile: I know how to access the container, so are the logs in /var/logs or how do I access the asterisk console if I'm in the machine?
15:05.21MLCwhat are "session timers"? controlled by parms timers and timers_min_se. I see the doc but didn't find anything that really explains what it is.
15:05.46igcewielingThey are another keepalive type thing, but again, it only operates on the current call.
15:06.29fileasterisk -r opens the Asterisk remote console
15:06.31igcewielingWhen they are set, but should not be, you'll get disconnected calls at 10 or 20 mins, I don't recall which. (assuming the default session timer value)
15:07.28MLCdefault is 1800 = 30 minutes
15:07.37MLCdoes that only serve to disconnect calls?
15:08.27hlokfile: okay I'm in it now what do i do?
15:08.50fileyou have to do a call, and then provide a link to the output so someone hear can look at it, interpret what is going on, and give you an answer
15:08.52*** join/#asterisk hfb (~hfb@47.139.20.75)
15:10.08hlokit is not producing any output when I do a call, can I check from the console if I registered properly?
15:11.25MLChlok: pjsip show registrations
15:11.40MLCholk: also asterisk -rvvv will give more console output
15:12.33hlokhmmm it says no objects found
15:13.10MLCdoes your pjsip.conf have a type=registration section?
15:14.16hlokMLC: nope
15:14.43hloki just copied the hello world doc https://wiki.asterisk.org/wiki/display/AST/Hello+World
15:15.18MLCdid you change sip.conf or pjsip.conf ?
15:15.30hlokI made pjsip.conf
15:15.59MLCsome providers need a registration section, some do not. Check with your provider and see if they have a sample pjsip.conf file
15:16.31hlokk
15:18.19hlokI don't have a provider to my knowledge.
15:18.46MLCare you trying a call between 2 internal phones?
15:22.32hloklinphone says registration failed: not implemented
15:22.59hlokMLC:
15:23.08hlokMLC: yeah that's what the tutorial says
15:23.39MLCtry pjsip show contacts and pjsip show endpoints
15:29.20hlokpjsip show endpoints found 1 object
15:30.33hlokhmmm linphone says "Could not start udp transport on port 5060, maybe this port is already used."
15:30.47hlokdoes it have to be on a different machine from the asterisk server?
15:31.04MLCyou can't run asterisk and a soft phone on the same computer without changing the ports
15:31.18MLCwould be easiest to put the phone on a different computer
15:32.09hlokMLC: ah thanks

15:43.48MLCSo back to my earlier question, are session timers only for disconnecting sessions, or could they also be used to keep the SIP port open with a keep alive?
15:44.58hlokhmmm I'm having trouble getting the ipv6 transports to show up in pjsip show transports
15:45.13hlokdo I have to load a special module for ipv6 or anything?
15:45.59fileno
15:46.12igcewielingnone of my phones support ipv6 so I've never bothered working with it.
15:50.10*** join/#asterisk hfb (~hfb@47.139.21.151)
15:50.18hlokshocked face
15:51.25hlokokay, I guess I'll put it up on one of my VPSs and try it over ipv4
15:58.09SamotWhy do you need another VPS? Can't you just run IPv4 on the current system?
15:58.25SamotCrazy but Asterisk can support _both_ IPv4 and IPv6.
15:58.53igcewielinghlok: none of my users use softphones.
16:03.00hlokweird it's not showing the udp ports to be open
16:04.12hlokfirewall says they are open, hmmm I'll check the docker config
16:04.20hlokigcewieling: what do they use?
16:05.34hlokyeah it was the docker config
16:06.31igcewielinghlok: Polycom and VTech SIP hardphones.
16:07.16igcewielingI think we have a few people setup with softphones recently, but those are on mobile phones and so work terribly.
16:08.48SamotWhat softphone?
16:15.20*** join/#asterisk [TK]D-Fender (~joe@216.191.106.165)
16:23.47hlokandroid has builtin softphone which depending on android version doesn't work great, linphone is also a viable softphone on android
16:27.01SamotI was actually asking igcewieling
16:28.30igcewielingSamot: Zulu for FreePBX customers (I think those are desktop only) and gloCOM a softphone from our Hosted vendor.,
16:28.59SamotOh, so vendor specific
16:29.45igcewieling*nod* That way our normal techs can support it and use the vendor support for help.
16:29.53SamotNot sure about gloCom but honestly, Zulu gets a lot of reported problems.
16:31.55igcewieling*nod* I don't know if the customer is still using Zulu.
16:33.45igcewielingThankfully, gloCOM is licensed with a per seat cost which makes for far fewer "installed it and they only used it once" situations.
16:34.25SamotYeah, that's why I like the Bria Stretto platfrom.
16:34.29SamotYeah, that's why I like the Bria Stretto platform.
16:34.42SamotSupport, per user seats and re-usable licenses.
16:43.43hlokweird now it's giving me the password prompt but is not accepting the password in the config file
16:52.14hloki am getting results in endpoints and contacts but it has their local ip
17:28.44igcewielingDo they provide end user support?
17:33.01SamotNo, you provide end user support.

17:36.49gohardtechI know this is sort of unrelated to asterisk, but can I ask a question about an SMS gateway?
17:44.03SamotAsk it.
17:45.34gohardtechDo my DID providers need to have SMS capabilities, or can I redirect them to a gateway that strips SMS first, and forwards SIP Voice traffic? Is that even a thing? Appreciate any feedback you may have.
17:47.18SamotYes, they need it.
17:48.23gohardtechtoo bad ;) thanks for the answer. Was hoping that wasn't the case.
17:51.33hlokokay for w/e reason it works via tcp
17:52.04hlokbut for some reason I'm still not getting any audio output on my linphone desktop app
17:52.15hlokwhat's the default codec?
17:57.35MLCyou specify that in your pjsip.conf with disallow and allow
18:02.58hlokoh so can i do allow=opus?
18:03.46hlokanyway I can see what the setting is from the console?
18:03.53MLCyou can try that
18:04.01MLCpjsip show endpoint xxxxxx
18:04.10MLCwill show the codecs defined
18:04.20fileif codec was a problem the call should fail, you wouldn't get no audio
18:06.59hlokfile: hmmm
18:07.10fileare you still using Docker?
18:09.10hlokfile: yep
18:09.53hlokit lets me place the call to extension 100 but I don't hear anything, though i think it maybe the linphone app, cause i tried with my voip.ms account can't hear anything there either
18:16.43hlokon the asterisk end it says it plays the hello world thing
18:17.02file"rtp set debug on" will show you RTP traffic that is sent/received in Asterisk
18:17.03hlokalso it seems i can't login via my other softphone that is on my phone where I know the audio works *sighs*

21:20.36allizomHi, feel free to point me to a more appropriate resource as this is not strictly related to asterisk. I'm trying to configure an ATA to use the SIP account my ISP gave me. I'm not able to register, even as the settings appear to be correct and I'm using the same ones on another device. What I'd like to understand is what receiving a 'SIP/2.0 408 Request Timeout' error, along with 'User-Agent: ZTE-SBC' and 'X-ZTE-Cause: "SBC-434
21:22.48snuff-workallizom: trying to use same SIP details on two different devices behind a NAT is unlikely to work well
21:23.22allizomsnuff-work: ok, is that true even if I use different local ports?
21:23.46snuff-workpartially depends on your router and what 'sip' fixes it tries to do
21:24.48allizomwhat do you mean by sip fixes? there's an option "SIP alg" and I disabled that

21:25.35*** join/#asterisk jasonwert (~w3rt@198.167.245.16)
21:26.14snuff-workthat would be it.. someone else may be able to provide more 'experience' on how running many SIP clients behind a NAT.. i had some a long time ago but my memory is hazy
21:29.00SamotA 408 Request Timeout is pretty self-explanatory.
21:29.12SamotThe request to the host timed out.
21:29.25SamotYou're not getting a reply back from the ISP.
21:29.37SamotSo either there is something wrong with the account at the ISP or you have a NAT issue.
21:29.42[TK]D-FenderOr the request never made it to them in the first place
21:29.48SamotEither way, it sounds like you need to call the ISP.
21:29.52SamotCorrect.
21:30.11seanbrighti tried calling the ISP but the request timed out
21:30.15seanbrightzing
21:30.29SamotBut if this ISP is providing you both Internet and Voice, then it's 100% their issue.
21:30.29snuff-workfirst check.. ensure the device has a default gateway set.. and a DNS (if u connect via dns)
21:30.41SamotWhat device?
21:30.55allizomwell, I'm definitively receiving replies from my ISP because I can see their User agent string
21:31.00snuff-workruns away from most NAT issues =)
21:31.04allizomSamot: I'm using a Grandstream ATA
21:31.25SamotAnd where are you seeing their User Agent string?
21:31.32snuff-worki'd almost build tunnels than deal with NAT in a substantial fashion
21:31.49SamotTunnels to where?
21:31.56allizomSamot: in a log on my ATA
21:31.58SamotThe other side would have to have a destination to tunnel to...
21:32.11seanbrightchina. a tunnel to china.
21:32.27SamotOK, the ATA sent the REGISTER request. It got a 408 Timeout.
21:32.36allizomexactly
21:32.45SamotThat means the ATA never got a provisional reply.
21:33.03SamotSo they aren't responding to your request for some reason.
21:34.00SamotYou should send the REGISTER, they should reply with a 401 or a 407 challenge. You'll send another REGISTER and they should reply with a 200 OK if everything is good.
21:35.23allizomit appears so. I'd like to make sure it's not an issue on my end (you talked about NAT)
21:37.19SamotIs the ISP providing you the Internet connection as well?
21:37.26allizomyes
21:37.40SamotDid they provide you with a modem/router combo or are you using your own router?
21:37.48allizomthe latter
21:38.07SamotSo do you have DMZ setup for your router in ISP modem router?
21:38.27allizomI'm not using their box at all
21:38.45SamotSo you're doing Layer 3 in your own router?
21:39.15SamotAnd what kind of router do you have?
21:39.44allizomI'm using a modem router which was provided by my previous ISP, and can be configured for use with other ISPs, I reconfigured it. It's a Technicolor, one minute for the model
21:40.10allizomTG789VAC
21:42.29allizomIt has fxs ports which I'm currently using with the SIP account from my current ISP
21:44.56SamotWell I would suggest visiting their forums or support site.
21:45.11SamotBecause not much help is going to be here in regards to dealing with it's settings and programming.

21:50.39allizomSamot: do you think this router could be involved with my issue? And if so why? Because of its NAT function, or because of its telephony function?
21:51.22SamotCould be both, I'm not sure.
21:51.32SamotBut this could be a NAT issue.
