Looking for decent SIP Trunking

I sell custom, managed VoIP iPBX's via www.gdnsinc.com, and am looking to attack the local small business market. Currently small businesses in the area typically have a couple of POTS lines from the local carrier AT

I have used callcentric, voipstreet, and les.net. I can recommend all three of these services. Callcentric appears to be the most professional, but they all work well.

SIP and DSL

I have try many dsl provider i cant never get call quality to be good enough to sell to business. DSL is not realiable enough to send call through.
But if you looking for a good SIP provider contact sales@idv.net
they have very good if not rock solid network for SIP trunking only no IAX stuff

I can't say I've tried it on a DSL connection, but I get perfect call quality from cable.

With IDV when the network up, everything is fine, but
IDV sometime still have downtime, I got about 3,4 times downtime in about 9 months, each time from 3,4 hours
Support is not really good, email is only way for communication. I can not get in touch the support phone after business hours
Billing is an issue with IDV also. I have services with them and in their customer-portal, they don't have some sort kind of CDRs or anything for showing usage traffic.

It surely depends on your ISP, but DSL does work just fine for VoIP. We have plenty of users that run an entire office off of a DSL line without any problems with a 2+ years track record. We find that a 3 Mbps down / 768 kbps up DSL connection is capable to serving 8 concurrent calls (G711 toll quality). Typically this connection is shared with web/email use, which works OK as long as there is QOS on the router to prioritize outgoing traffic on the more limited outgoing channel. Of course it helps when the end-to-end RTT is <30 ms (for us within Los Angeles).
We typically have more trouble with cable connections, especially in areas that are oversubscribed and the outgoing bandwidth gets saturated (huge jitter, 20 ms - 200 ms, often some packet loss). In other areas, cable is just as reliable if not better, simply because the buffering works differently: starting a large download does not cause traffic at the ISPs end to be queued up.
Just sharing some experience.
