Hi

We have a customer who is experiencing intermittent network issues.  They run 2 physically separate networks which access the internet via 2 separate broadband routers on separate broadband circuits.  One network runs their IT systems and the other runs a VOIP system using SIP trunks over ADSL.

Both networks experience the same problems, namely random slowdowns and general unresponsiveness on the IT network and broken/poor call quality and calls dropping on the VOIP network.

There are 3 PCs, 1  2003 SBS server on the IT network and 4 handsets and 1 Win 7 Pro PC (which runs 3CX VOIP software) on the VOIP network.  The 3CX PC and server are connected via an APC UPS.

Every piece of equipment on the VOIP network with the exception of the Snom 320 handsets has been changed along with the UPS over the past 8 months.

We have experienced hardware failures over the last 6 months as follows:

3 x routers
1 x Firewall
1 x PC
1 x UPS

We are pretty certain we know the cause of the problems, but would appreciate a second opinion.  I’m not going to put down our thinking here just for now so I don’t bias any replies!

Thanks in advance.
