[cisco-voip] List of SIP Internet Providers

[Lelio Fulgenzi]

You hit the proverbial nail. I spec'ed out replacing our PRIs with SIP with dedicated layer 3 service and it was double, not including one time fees.

Plus, with all the issues with fax service, we'd end up keeping a couple of PRIs anyways more than likely.

Now, if we were to get SIP service from our isp, then that might work. But I'd like to get a longer term contract. Deal with porting numbers can be a pain.

I think it depends on quality guarantee versus cost.  For call centers (like Clifford points out), quality would usually be of upmost importance.  But for general usage or college campus environment, maybe quality is not of upmost importance and cellular-like quality is more than acceptable.

Or, in some cases, the internet provider may also be the ITSP/SIP provider which may provide QoS control as the traffic would never leave their network.

I've also seen where a customer's WAN carrier also provided the SIP trunks over their existing MPLS network.  It usually requires a slight increase for BW on links, but the trunks and local loop charges are already being paid thereby drastically reducing the costs associated with a dedicated L3 circuit just for SIP traffic.

It's always a good idea to understand the full cost of the service rather than focus on 'per minute' charges.  I've seen several customers that assume SIP equals lower costs only to find out that dedicated L3 trunks can cost more than a couple PRI lines they are replacing.

Anyways, my 2 cents.

One question I have is whether people use SIP providers over their regular internet connection or do the get a SIP provider who provides layer 3 to the site?

I've been using voip.ms for some time.  They do a pretty good job.

I have been asked to look at moving our SIP trunks so they over the Internet.  An example of a company that does this in the US is bandwidth.com<http://bandwidth.com>

I am writing to find out if there is a list of other companies such as Bandwidth and if so where I could find it.  I have googled this and I am unable to find one.

Thank you in advance for your help.

John
