What is the lowest channel no. supported in agora web? - agora.io

We are looking at the agora web tutorial 1-to-1 repository on github. The channel no. specified is 1000. We would like to know the lowest channel no. supported.
Channel: <input id="channel" type="text" value="1000" size="4"></input>
The documentation v1.12 mentions number of channels supported is unlimited.
We appreciate the cooperation of forum members.

There is no limit on this. As far as I know, the channel name will be interpreted as a string.

Wechat : does an SDK / API exists?

I'm online on wechat (an instant messenger, not to be confused with weechat, that is an IRC client) and following a lot of groups for work. I'm searching for an SDK, an API set, to be able to automitize info collecting from groups and or individuals.
But i'm not aware of any way to do it.
Please, this is NOT an 'opinion' question, I'm litterally asking you if you know a way to receive data from weechat, because I cannot find it.
I see the area on weechat website where a company can ask for accces to API, but, really I cannot find other tools.
Edit 1: Chinese DOC, I think: https://open.weixin.qq.com/cgi-bin/showdocument?action=dir_list&t=resource/res_list&verify=1&id=open1419318183&token=&lang=zh_CN
Edit 2: Chinese DOC more similar to a JS api :http://work.weixin.qq.com/api/doc#10029/%E5%A4%96%E9%83%A8%E8%81%94%E7%B3%BB%E4%BA%BA%E9%80%89%E4%BA%BA%E6%8E%A5%E5%8F%A3
Obviously, use google translator !
As from my OP, there are some docs, official docs, but the real problem is that to create even a simply Mini Program, we need to subscribe (paid) and also paying at one point a chinese-only page asks by country and the list simply does not include Italy, so I simply cannot subscribe.

Tokbox OpenTok client to call another client

I want to build an application where it is possible for one client to call another client using webRTC. I've started to look into webRTC providers and I've found Toxbox among others.
Is it possible, using TokBox OpenTok, for a client to actually make a call to another client (similar as a regular phone call)? From their docs and specifications it seems that it is only possible to create a "session" (a room in which participants meet and chat).
Am I missing something, or are they only providing sessions that people join/leave?
Twilio seem to offer what I need here,
but I find it strange that I cannot find something similar at Tokbox.
Thanks,
Muff
Yes it is possible.
You need to make the distinction between the type of API the platform exposes to what you can do with it.
While the OpenTok API is built around the concept of a room/session - you can easily use that concept to create a call. There are many openTok developers who do just that.
Twilio indeed offers the same capability - as are many others (a partial list can be found in this report - https://bloggeek.me/webrtc-paas-report/ - while the report is a paid one, the list is available on that page

Subscribe a Device Group (notification_key) to a Topic

I've recently encountered this post where the general idea is how to subscribe a user to a topic, with multiple devices. I provided an answer, suggesting to make use of the Device Group, then doing the batchAdd on the server side.
But I was wondering if it was possible to subscribe to a topic using the device group notification_key?
I haven't seen anything that mentions something like that in the docs.
The notification key is described in the doc as:
All devices in a group share a common notification key, which is the token that FCM uses to fan out messages to all devices in the group.
So I thought maybe it was possible to use it. But can't find anything that mentions it though. I've looked around the community for any other similar posts, went through the docs, but most of it are just about subscribing a single device to a topic.
Was my answer to the post a good method? Or did I just miss something where there is already a process/flow on how to actually do this?
I haven't really tried it out myself, but it was the only way I could think of. I'm still studying about GCM & FCM and I would appreciate it a lot if someone that tried it before can shed some light about this.
You cannot subscribe a device_group to a topic. The way to achieve this would be to subscribe the tokens associated with the device group to the topic either individually or in batch.

Can a Google Cloud Messaging message be sent from browser/Javascript?

Question says it all. All the examples I can find are for server<-->android.
I'm looking for Javascript-->android
Paid version, try PubNub (Push to Android Example) or Pusher API tools.
For open source solution, you might try PushSharp
Note the real trick is obtaining the RegID from your device. See the answers in this posting to understand better what is going on...

is it possible to identify telecom provider by mobile or phone number?

There are ulimited online bulk sms provider supporting Restful API. Mainly I look into Nexmo, Tropo, Twilio pricing in different countries.
Let take an example sms to Brazil.
[ TROPO ]
2¢ / msg
[ Nexmo ]
3.63¢ / msg
[ Twilio ]
Twilo offers based on providers. see the pricing.
Vivo 8.3¢ / msg
Claro 8.6¢ / msg
TIM 1.2¢ / msg
Oi 8.3¢ / msg
So, What I want is before sending SMS, I want to identify the Provider. See the example sending sms to TIM is cheaper in Twilio but others Tropo and Nexmo are cheaper. If there is a way to identify the telecom provider then I can program which API to use before sending sms. I don't know this question should be posted here or not. Is there a way or api available to identify this? Thank you.
I didn't see ready solutions, except databases in billings (in most cases they are detailed as needed for concrete needs)
The "number one" source is ITU. Link to docs - http://www.itu.int/oth/T0202.aspx?parent=T0202
It's official source, but it isn't ready to consume database. You must spend much time to manually create database.
There are some preparsed databases, as http://en.allworldsms.com/html/phone_codes.php ...
it's ugly, but it contains logos. And it's not downloadable in one file, but it's still easy to consume.
http://www.data24-7.com/git.php offers a free look up service if you want to use the web based panel they have. If you want API access they charge a sub-penny rate per look up. When I was using it the rate was something like .006 cents. Also the data was only about 90% correct. They may have improved it since then.
You can get more then just the provider, you can also tell if the phone number supports SMS, if it's wireless and what the greeting interrupt tone is (the number that by-passes the voice mail greeting).
