In SIP, clients periodically register so that the server knows where to find them. If registration fails, the console will tell you why, provided that you have set the verbosity high enough.
In the world of VOIP, an extension is not a real loop of copper, but a sequential list of things to do when a number is dialled. This extra step is where Asterisk gets its flexibility. With your extensions. The syntax is still INI-like. Under [users] , we add the steps for each extension, numbered sequentially.
In this case, there is only 1 step for each extension: to dial a SIP user. Ok, time to do a reality check. For a start, you need a way to dial the outside world, and let the outside world dial you. Mohammed: For this particular setup, the sip. In your case, Centos7 has a firewall and SELinux so definitely check the log files. Way to dial the outside world, and let the outside world dial you. Also i can not get video between 2 grandstream telephones, when i using another SIP server kamailio i have video.
Please share on the comment section if possible. Thank you. Regards, Daniel. Hi Mike I know this post is a bit old, but I still wanted to thank you a lot for this wonderfull How-To.
If I have left out any steps please let me know. I chose to build Asterisk from source on a CentOS 5. My current setup includes one analog line via the zapmicro card and one line via GoogleVoice. In order to make everything work together, several packages that are not installed by default are required. This article focuses on building your Asterisk box from scratch, there are several pre-built distributions such as AsteriskNow and trixbox which are also excellent options.
I happen to like to build from scratch, the pre-built distributions require the deletion of all partitions, building from source allows you to use the latest stable version and add on to existing servers in your home or organization. I also like to do things the hard way just for the learning experience. For all intents and purposes this article will utilize CentOS 5. I prefer to use CentOS since it is a rebuild of Redhat Enterprise Linux and it is well tested and found in many professional settings.
You can use any distribution of your choice, but the steps may require slight modification. I have a few spare computer laying around, and one already had a basic installation of CentOS 5. If you are starting with a blank slate, you can obtain the ISOs for installation here. Please choose the right architecture for your machine.
First things first, either login as root or a user with sudo permissions, in the terminal issue the following:. These RPMs are the minimum required to ensure that Asterisk configures properly. They can be installed in one shot using the command:. In order to use the MySQL database features of Asterisk you will need to add the following packages:. I like to keep the source code for the programs I install space permitting. For completeness we will build the dahdi packages from source, this will ensure that even if you do not have any analog hardware installed at present, it is simply a module load away.
Person B as an audio participant 3. Person C as a caller from a phone system PBX based 4. Screen sharing is possible within video sharing participants Here video and audio logs are generated and stored on a file system. Not sure if Openfire can communicate to a File System or not and we get a handle for these files that we can store into an application.
Hope I am clear here! Thanks, Dish. Soraya Jul 11, at UTC. Hi Dishi, There are so many questions here I think you need to clarify some points. If you want a PBX, there are several option, mostly based on Linux. You just download the distro and install it on a Virtual Machine in order to test it. Not all PBX have it. You could find Openfire server on Elastix, it's integrated.
Shannon gived you a good explanation about it. Sparks it's an IM client that you could connect to Openfire server. None of them works with video calls. If you need to video conferences and document sharing including recording of the conference there are some other devices that you could use, even If you don't have a PBX system.
For example "Aver", that's the only one that I've working so far. Good luck! Thanks Soraya. That helps. I could proceed with the FreePBX installation on virtual machine.
