One of my clients a used automobile dealer needed a new PBX. Mind you they had/have a PBX before called talkswitch which I installed about 6 years ago. And this is the 2nd unit that has been in operation in the last 6 years the first failed and replaced with a warranty unit. They were continually complaining about can't hear incoming/outgoing calls. They had ATT come out to see if they had line problems. I told them prior that it was the talkswich. But encourage them to get a 2nd opinion. It proved I was correct as the ATT Tech told them that the talkswitch PBX was the issue. I approached them with can't ignore deal. Some background to what they have: 3 POTs lines, and 7 extensions. Well this small of a system is a no brainier to Elastix. I built up an Intel Atom 230 system with 1 gig ram, 100 gig hd. Added am openvox A400P with 3 FXO addons. Installed Linksys PAP2T FXS Gateways to pickup the Analog phones. Put it all in over weekend and whamo it is up and running with Ring Groups, Voice mail and music on hold. Which btw is coming from the PAP2T since the analog phones they have put lines on hold internally so i setup the option "imusic" in the linksys gateways. Which contains one music file. So far i have not seen more then 3 calls going on at the sametime, which the Atom cpu is handling just fine. I had a bit of fear that might not be a strong enough system. I am working on another system to go in soon with a very small research company it will also use the Atom CPU, but this one will have 3 IP phones. They are looking at the Grandstream 2000 or 2020.
