Hello, not too many places I can ask about this so I hope we can work this out. I know a lot of us know about asterisk but im shifting my PBX into ESX. I currently run a bluetooth trunk that works amazingly good apart from the dtmp. I have been holding off buying new hardware till I got in up and running to my standards in ESX.  It would be nice to shift over the bluetooth system for now but dont have high hopes for that one.

What options do we have to run a GSM trunk in our virtualised PBX's and keep them as our 'best mates' ;-)

And are their many people out there running a strong PBX through ESX?  Many tryed Microsoft's V-Hyper as a comparison?

Possibly a bluetooth USB dongle will work?

Otherwise I think you would need to change to a GSM Trunk with an Ethernet i/f

I use one from Portech, http://www.portech.com.tw

I would strongly suggest against running Asterisk under a virtual machine, particuarly if if uptime and call quality is important.

It may work just fine but the reality is there are certainly no guarantees and it's certainly not recommended for any production systems. I've played with trixbox under hyper-v and it worked well.

Would I try and run it for a large scale system where uptime is important? Not in a million years.

I'm with sbiddle - I've run a test asterisk system under VMWare server - it worked, although voicemail suffered from a stutter.

Even a small scale production system I would strongly recommend running on direct hardware ...

Running it under VMware is fine (well at least for small installations). ESX should offer you the ability to guarantee CPU/RAM etc. and once you find the balance here the system will run perfectly.

Remember that in terms of reliability etc. its a double edged sword to hassle VMware. Generally since asterisk is so easy system wise hardware quality is often overlooked (and many places I see even suggest using old PCs). Generally your VM server is going to be highly specced and reliable with dual PSU etc.

Vmware to me sounds risky. I myself had problems running proxy servers built on freebsd (bellieve it was driver issues?). Your load would be your definite downside as with MeetMe and other applications asterisk will be transcoding on the fly and performance could suffer. I've managed to make asterisk hang and crash with 30 simulatenous calls converting from alaw to g729 built on a Dell PowerEdge 1850 with dual 3.2ghz CPUs - you can dramatically reduce the load by natively bridging calls i.e. use the same codec across all "hops"
