00:01.59 | aNullValue | lol |
00:02.04 | aNullValue | ok, thanks for the anti-answer |
00:06.01 | Samot | What anti-answer? |
00:06.20 | Samot | You claimed to have searched the Internet and couldn't find any SIP phones that supported video that wasn't Android. |
00:06.38 | Samot | I've given you three vendors that have multiple options. |
00:06.52 | Samot | Are you looking for a specific phone? |
00:08.03 | aNullValue | literally all three vendors you mentioned (poly, yealink, grandstream), of their phones that i can determine support video calling, they are _all_ built on ancient versions of android. it's right there on their spec sheets. |
00:08.42 | aNullValue | i'm not looking for a specific phone; i'm looking for someone who had experience and could give advice (the first words i said), and elaborated that i'm worried because all of these phones seem sketchy to me |
00:09.46 | Samot | Sketchy? |
00:09.59 | Samot | They are like in the top 5 vendors in this space. |
00:10.09 | Samot | Polycom is at the top. |
00:10.21 | Samot | So sketchy that fortune 500 companies use them. |
00:10.24 | aNullValue | yes, i understand that those are among the best vendors |
00:10.27 | aNullValue | jesus fuck i'm aware |
00:10.40 | Samot | So if you need a solid phone that does video, Poly or Yealink. |
00:10.40 | aNullValue | these _models_ are what worry me, not the companies |
00:11.01 | Samot | OK well as someone who uses them on a large scale, they are fine. |
00:11.11 | Samot | They work just fine. They have firmware updates regularly. |

I am trying since some time to develope a channel driver for asterisk or alternatively a SIP->GSM gateway similar in scope to chan_dongle, but based on a different approach (e.g.: using ModemManager). I wrote down the code interfacing with MM and thus can track incoming calls and so on. My problem was I couldn't wrap my head around PJSIp and so on. so was seeking for recommendations. |
14:29.14 | mrkiko | Maybe I can handle calls on my own and talk to Asterisk somehow to tell it something like - go read audio from serial / write it to serial ? I managed to handle audio also, doing calls from the console, but with a standalone app, not within asterisk |

17:37.36 | aNullValue | anyone have experience with Avaya Vantage phones in Asterisk? i'm wondering if they "just work", as the docs seem to indicate, or if they are difficult and aren't great SIP phones (like Avaya's 96x0 and 12xx lines, which I've worked with in Avaya environments) |
17:45.51 | sibiria | COVID-1984: most DID providers also offer shortcodes and relaying of SMSes sent to them |
17:47.05 | sibiria | but short codes are expensive everywhere, even when you buy just a prefix on a shared one :) |
17:47.48 | COVID-1984 | @sibiria can you recommend a provider that explicitly states they support receiving shortcodes? |
17:48.01 | COVID-1984 | I tried voip.ms and about 90% of shortcodes I've not been able to receive. |
17:48.52 | sibiria | voxbone, infobip, sinch |
17:49.51 | *** join/#asterisk opal (~wowaname@volatile/founder/wowaname) |
17:50.45 | sibiria | i don't know the full list of countries they provide short codes for, but we have such registered with these three providers in a handful of european countries |
17:51.08 | sibiria | messagebird also provides short codes |
17:51.59 | COVID-1984 | thanks will try those out and switch to whomever is the most confident about receiving shortcodes long-term. |
17:52.13 | COVID-1984 | Too bad banking and many other services (Uber) still needs them |
17:52.16 | sibiria | and regarding reliability, i have no concerns about any of these three |
17:52.35 | sibiria | at least not in the scope of SMSes sent to them through european cellular grids |
17:52.55 | sibiria | they've been entirely reliable for us |
17:55.21 | COVID-1984 | will need to receive US shortcodes, and receive them on browser or app (software)... I'm guessing those three don't require any hardware (they are SIP) |
17:55.40 | drmessano | What do you mean you haven't been able to recieve 90% of them? |
17:56.01 | sibiria | they relay SMSes over REST towards an http endpoint of yours. very basic, and the most common solution for these things |
17:56.10 | drmessano | Yep |
17:57.44 | COVID-1984 | drmessano: I ported my phone # from Google Voice to voipms and about 90% of the services I was using and needed to send shortcodes (airbnb, uber, etc)... they cannot be received on voipms (and voipms docs say they cannot officially support shortcodes)... And googling about it shows very little about who official supports them. |
17:58.26 | COVID-1984 | sibiria: nice, sounds like it'll work well |
18:09.12 | Samot | Well shared short codes are being phased out. |
18:16.02 | COVID-1984 | 'shared' meaning? |
18:16.39 | sibiria | that you get a prefix rather than a whole short code just for yourself |
18:17.10 | sibiria | short codes in most countries are 5 digits, sometimes 6. very limited availability, high cost to subscribe to one |
18:17.44 | sibiria | so customers can use a shared one where the text message must contains a prefix to be relayed to you |
18:18.31 | COVID-1984 | ok, was just talking about random shortcodes from services for sending OTPs |
18:18.49 | sibiria | what do you mean by "random short codes"? |
18:18.56 | COVID-1984 | there's the shortcode itself, and then the messages sent within it, right? Which is OTP in these cases. |
18:19.25 | COVID-1984 | sibiria: when you login to your bank, for example... They don't just use a password. They have to send you an one-time-password via SMS often. |
18:19.36 | COVID-1984 | This OTP they send via SMS is done using a shortcode SMS, right? |
18:19.47 | sibiria | sometimes, sometimes not |
18:19.55 | sibiria | more common with an alphanumeric sender in my experience |
18:20.33 | sibiria | there's technically no difference |
18:20.41 | COVID-1984 | Well voipms classifies them as "Shortcodes" and that is why it says it does not support them. |
18:20.50 | sibiria | it comes down to what the SMS provider you use will allow |
18:20.52 | COVID-1984 | Even more receiving only. |
18:21.12 | sibiria | some of them will relay SMSes on your behalf using any sender, whether numerical or alphanumerical |
18:22.12 | sibiria | the providers we use, and the european countries we operate with mostly, have no restrictions on SMS sender IDs |

18:22.42 | COVID-1984 | Cool. voipms citied some US laws that make it difficult for them to support |
18:23.30 | sibiria | some countries restrict this in terms of having to register the sender ID with all providers operating in the country in question, on national level |
18:23.42 | sibiria | but, again, as far as europe goes it's mostly still entirely open use |
18:24.02 | sibiria | can send an SMS from "12345" or "fuckface", and providers in most countries will relay it as-is |
18:24.20 | sibiria | without us having to "register" or be affiliated in some way with the sender ID |

23:49.04 | drmessano | I don't have a crystal ball. I do know in 15+ years of doing this that SIP ALG on anything is generally "the suck" and especially on Ubiqiuiti and PFsense boxes. |
23:49.18 | drmessano | So if it was enabled, and you disabled it, that's a great start. |
