We made the change to Maser�����s VPLS solution ( A layer 2 MPLS cloud) over a year ago, we have different local loop connectivity anything from a T1 up to 100Mb.
We use QOS for both video and voice and do not have any problems with it, it does what it says on the tin. The biggest benefit of VPLS from my point of view is that we can use whatever routing protocol you want to, we use OSPF, we also have public IP connectivity provided on a second port on the Masergy MIB, that allows us to use the same circuit for internet access well if needed. Masergy also hands the circuit over as Ethernet, so if you have a layer3 switch, then you do����t anther router. Which if you are looking at running a DS3 circuit or greater at full rate, with QOS, you will need a router with plenty of horse power. From experience of VOIP all over the world, if you want a reliable connection, you need some form of QOS, both inbound and outbound on the circuit.

Each office has their own dedicated Internet connection. All data and email is centralized in our main office with each satellite office having their own phone switch. We use VOIP for inter office communication and voice mail. We do not do video conferencing yet but do make use of VPN and remote desktop services for folks working remotely. I have several vendors pushing me hard for changing all our circuits over to MPLS. It seems that the price of doing this may be more than what everything currently costs now. I have also looked into leaving the P2P Ts as they are but switching most of our dedicated Internet connections to Comcast Business cable. Doing this would multiply my Internet bandwidth by a factor of 6 but cut my monthly costs at our main office by more than 75%. I've read up on MPLS and it seems that the QOS is indeed better but it also sometimes has packet loss issues. I'd appreciate any opinions on the switch to MPLS and any hands on experience stories that you'd be willing to share. Thanks.
