Management has a fear that switching from AT&T MPLS to a AT&T Wired VPN soltuion will cause some speed/etc issues between our four locations which have a total of 300 users.
At a previous employer we we did not have MPLS and used VPN to get to our remote ERP system.
1. Do you know of anyone using VPN between locations ?
2. If so, do they do VOIP between locations ?
3. Do they use SoniceWall VPN hardware ?
There is an old http://www.networkworld.com/reviews/2006/022006-ssl-voip-test.html
article, but I would like more up-to-date articles.
