Assuming that you are looking for business service, we have been testing the following: Broadvoice broadvoice.com
Voice Eclipse admin.voiceeclipse.com/cgi-bin/ … d=a1x4w9u9
We have found both of them to be reliable, except that our toll free number through Broadvoice has been down for several periods.
The big problem, however, is in the terms and conditions. Broadvoice has the following restrictions on “business service”
“the BroadVoice Business Plan does not confer the right to use the Service for auto-dialing, call center activities, continuous or extensive call forwarding, call relaying, telemarketing, fax broadcasting or fax blasting, and that you may not use the Service for those purposes.”
VoiceEclipse has no such restrictions that I can find.
I can’t imagine that I wouldn’t run afoul of the BV restrictions in a very short period of time.
If you are just loooking for residential service, then I would probably go with BV, because of the cost factor.
Hope this helps.
