Hey all, I have done a bit of research and cant seem to find anything really solid on these questions. Im hoping I can get 1 or more (hopefully similar) answers here.
I have a client who is looking at moving from a traditional PBX to a VOIP system. I have experience installing asterisk based systems for smaller clients, but this one is going to be a bit bigger (Many thousands of phones)
A few questions:
What is the upper limit of connections that one would recommend on a single asterisk box? This is disregarding the obvious hardware factor, and taking into account software only. I am planning on just stringing together multiple boxes through IAX, but I am trying to get an idea of how many boxes we are talking about here.
The customer has 1 or more DS3’s. Does digium make a DS3 card ? I cant find anything substantial, but I keep hearing rumors of one in development.
Does anyone have recommendations for Wireless (ie 802.11) phones for installation that work well with the typical asterisk setup ? Most of my experience has been with Polycom, which has worked well, but they dont offer much in the mobility department.
I want to install asterisk-1.4 on RedHat EL, rather than use AsteriskNow. Does the GUI found in AsteriskNOW come included in the standard asterisk-1.4.0 installation? Or is this something I am going to need to download from somewhere else ?
Thanks for any information you can provide on these !
