I am grateful to Aaron for providing the SS service and the time he invests for free for us to be able to use it for free.
After SS went down the other day, I decided to install 3cx to see what it was like. I understand that SS is an experimental service and with that comes the risk of downtime, Aaron has been upfront about this, and it's a risk I'm happy to take. We rely 100% on our VoIP for outgoing, incoming, and emergency calls so needed to get it up ASAP. I contemplated installing Trixbox but as I'm a bit of a noob with it and coupled with the limited success I had with Asterisk in the past put me off. Actually I WILL be having another go with Asterisk on the Fonera once I get a little Trixbox experience. I suppose I could set up the Trixbox and then copy over my sip.conf and extensions.conf file from my Trixbox to the Fonera running 1.4 Asterisk and hopefully that will allow me to cheat my way into having Asterisk running on the Fonera with minimum pain

!
Anyway, after SS went down the other day and not knowing how long it would be down for I thought I had better set an alternative up before I suffered injuries from other members of the household. I had looked at 3cx in the past but didn't think it would be that great, and it required P4 hardware which is my main machine so didn't want to install it on my main machine. I had tried other Windoze based PBX such as MiniSipServer, Axon, and SIP PBX2 in the past and managed to get them set up but noticed that sometimes SIP PBX 2 would deregister itself. It was probably an error on my part as I was rushing around trying to set them up and didn't give it the time I should have to be fair. However, all three programs consumed very little resources and ran happily on the P2 so I will definately give them another go at some point and report back. With that in mind I thought I'd try 3CX as that sees itself as a grown up PBX for windoze. I managed to get hold of an older version from a few years back and it is running on my P2, 350MHz, 128MB RAM successfully.
Currently I have 2 extensions registered, 1 of these is an external extension, and 16 VSPs registered. They system could do with a bit more RAM but appears fairly stable. It is totally point and click and I had the basics setup within a hour or so, considering that I had never used the program before, I thought that was quite good. I am only using the basic features such as LCR, Follow me, and time based calling at present and I was surprised how easy they are to set up.
The fact that it runs on Windoze and quite old hardware is a big bonus! Overall I am quite pleased. I really didn't think it would be so simple.
I have deregistered my VSPs from SS and will test the new 3CX system out for a few weeks to check stability. I'm going to come back to SS after that and install Trixbox on the P2 and Asterisk on my Fonera to see if I can get it going. Would be great to have a 5W Asterisk box!
