Marc,
We went with Broadvox exclusively because we wanted to deal with the best, most reliable SIP carrier. Price was secondary. We have sold a few accounts and I must say the service level is deteriorating rapidly.
During the cutover process we get the usual cryptic emails, but never a real person - a project manager - to see an order through to implementation. We end up going to my agent sales manager to complain.
At this point, we could never sell Broadvox where someone is moving and there is a specific port date. IMO, there is no way Broadvox would make it. There are people at Broadvox that either misplace orders or stop them from going through for some reason and then you are standing at the account, waiting. No port, sorry. The only possible way we could sell Broadvox now is when current services are in place and would remain active throughout the switchover.
We anticipated failure and/or unnecessary delays on our last large Broadvox cut and had the customer put in some POTs lines as a failsafe to forward calls to; without that, we'd be sued by now.
Thinking that we have had just a string of bad luck, I did a web search for 'review Broadvox', and even though the reviews are older, they are all very, very poor.
Frankly, the 'when we get to it' attitude is scaring the crap out of me now.
The fact that about every two weeks on a couple of Broadvox accounts goes offline is not too terribly reassuring either.
We are thinking of giving Voxitas a go. Do they now offer name and name caller ID? At one point they didn't and that was why we decided to go to Broadvox.
When we are looking at SIP it is all about dealing with a company that we can rely on not to leave us twisting in the wind. At one of our Broadvox accounts, they ported all the numbers except the customer's main BTN and fax, reason never known. So for a month now, after several resubmits of LOAs, we find that someone at Broadvox is stopping the port, for some unspecified reason, since the LOA is perfect.
Afraid and apprehensive, more and more, of SIP.
