I have a slightly abnormal application compared to what you find when browsing around Asterisk/VOIP websites and I am looking for advice on choosing a distro or package for the PBX and advice on softphones.
This is for isolated partyline/conference systems with < 100 phones, usually more like 10 phones.
I have custom analog mics/speakers that will connect to some embedded board with some kind of VOIP client on it. The mics are all push-to-talk so they aren’t passing audio unless someone pushes the button.
I want the phones to automatically join the conference, so all people need to do to talk is put they ear to the speaker and all they need to do to talk is hold a button down. I’m hoping there’s an app in the debian or centos or whatever (ARM) repositories that can do this. Or at least an easy library.
Will getting up towards 100 phones on a conference cause problems? There will never be that many people talking or listening at once. Or how instantly can a phone connect/disconnect from a conference?
Should I use one of the fancy distros like Asterisk now, or just install some barebones asterisk. The server machine can be a real x86 machine.
