Internet Telephoning to DR?

Lately I've been getting unacceptable results with Dialpad - many "misfires" while still being charged, and very poor quality when finally connected.

I see that another such service, Iconnecthere (Deltathree), has apparently raised its rates to about 21 cents/minute, but perhaps without being able to call a cell phone at all.

The third choice I know, Net-to-Phone, still claims reasonable rates but requires a $25 payment to find out.

Could it be that they have reduced their bandwidth? Have their own costs been increased, perhaps?

Sam's Club's call card rates have gone up too, to about 21 cents/minute. This card has no connection fee (except through a pay phone) and no expiration.

I'm very familiar with the cards from Nobelcom - more hidden charges than you can shake a stick at - but is that now the only way?

Thanks for the responses.

kjdrga, don't be dissuaded from trying Dialpad just because it has not connected me well to the DR lately. Before, it was great, and it's still pretty good domestically at 3 cents/minute (about 12 cents/min to the DR, including cell phones). The problem might be with my internet connection, for example.

One thing I especially like about Dialpad is that you don't need to install it, but use it from a browser window. It works therefore from an internet cafe.

It's discouraging to see the prices of phone calls to the DR go up, even as they're going down to other parts of the world - reminds me of air travel.
