I'd agree that IP DECT is the best option. Again I have tested voice over Wifi and never found it to be 100% reliable. Lee Mason Optimal Projects Ltd www.opl.co.uk www.backupsanywhere.com

I don't think that the MSA30 is an iscsi server in it's own right. If you just want to try iscsi or even nfs storage with ESXi 5.1 then why not get another old machine (even a desktop would be) and run Openfiler on it. Openfiler is open source and provide a host of facilities including iscsi...

First off the Trixbox project is pretty much dead now so if you are just starting I would suggest a different distribution such as the FreePBX ISO or PBX in a Flash (PIAF). The method of connection to the Topex GSM Gateway very much depends upon the model being used. I believe they produce a...

If you just want the CSV's to import into your billing system these are in /var/log/asterisk/cdr-csv. The main file is Master.csv (older versions have .1, .2, etc after the file name). However a better way might be to query the MySQL database. The CDR database is called something like...

Many of the Thecus models support printer servicing for both USB and networked (IPP) printers. Here is one: http://www.thecus.com/product.php?PROD_ID=17. Lee Mason Optimal Projects Ltd www.opl.co.uk www.backupsanywhere.com

I found this: http://www.opencode.com/solutions-1-11.php. But depending on what you are after doing specifically there might be other solutions. There are some pretty nifty scripts for PBX in a Flash (Asterisk based) to do a lot of different things. Lee Mason Optimal Projects Ltd...

It looks from the phone range given that the subnet for the phone network will be 255.255.224.0 (if they are all in the same subnet). This will encompass the phone ranges required. Is that correct? The phones may also be in different subnets (say for each floor of a building, etc). Ask the...

You could investigate some sort of WAN application optimisation. Have a look at either Riverbed or Replify. If you are going to use VMware Replify would be good as it runs as a virtual machine. Both systems will optimise the traffic across the WAN and can give 80% to 90% performance...

Check the Exchange server and make sure that the trixbox and Elastix server IP addresses are setup to allow the Exchange server to relay mail for them. Lee Mason Optimal Projects Ltd www.opl.co.uk www.backupsanywhere.com

You will need a lot of additional software and licenses to setup ACD queues on the Mitel 3300. You will also need a Windows server to run the additional software on. Your Assistant (YA) is the desktop software that can provide a view (and control) of ACD queues for agents and supervisors. You...

Have a look at ShadowProtect. It's a very good product for creating image backups of Windows Servers. I would second the suggestion of holding an offsite copy of the backups for Disaster Recovery purposes. Either by cycling media offsite or by using an online backup service. In my view...

It seems a bit of a risky configuration to have a RAID 0 for the data and no valid backup. It might be good to buy a low cost NAS device and maybe use something like rsync or robocopy to make a copy of the data on a scheduled basis. This obviously won't help in terms of offsite copies being...

If you are looking to learn Linux for business applications I would personally install Centos. This is because it is based on all of the same packages as Redhat Enterprise Linux which is most commonly used in larger businesses. Also Centos Linux runs a huge proportion of the World's web...

If you are interested in Asterisk in more details and a bit of the internals have a read of Asterisk The Future Of Telephony (Often called TFOT). It is published by O'Reilly but can be downloaded free. Lee Mason Optimal Projects Ltd www.opl.co.uk www.backupsanywhere.com

How much data will you be backing up? It might be worth looking at some sort of online backup service. The problem with removable disks or tapes is that you have to remember to swap them over every day (or someone does) and to take them offsite (for DR purposes). With online backup you can...

The Thecus NAS that I already mentioned comes with backup software for your client PC systems to backup all of their data to the NAS device. If you have an old server that you want to convert into another NAS device then you could use OpenFiler (www.openfiler.com). This is open source software...

Have a look at one of the Thecus NAS boxes like the N4100PRO: http://www.thecus.com/products_over.php?cid=10&pid=77. I know it comes with some client backup software but not sure of the facilities available within this software. Lee Mason Optimal Projects Ltd www.opl.co.uk www.backupsanywhere.com

What sort of backup drive do you have? Lee Mason Optimal Projects Ltd www.opl.co.uk www.backupsanywhere.com

H.323 is not good with NAT anyway and can be a real pain to setup. SIP is better but you don't have this options. So a VPN connection would be best but obviously you need the hardware/firewall at both ends to support this. Possibly a firewall to firewall IPSEC connection would be the best...

Also have a look at Thecus (www.thecus.com). They have a great range of NAS devices. I like FreeNAS as well and also OpenFiler but I can see your point as for small NAS requirements some of the pre-built boxes are very good value and offer a lot of facilities. Lee Mason Optimal Projects Ltd...
