I have been using sonovoip.com more than a year and I did not had any issues with them for some time ,but 2-3 months back issues start occurring.
The first issue I found with them was that even though they are charging white rate for a particular destination my calls was terminated through a grey carriers where most of the time calls were not connected , when I opened a support ticket , they said handling rate is not there job and to contact the sales department , then I explained it is there responsibility to solve my issue , they listened and said it has been resolved. But over the last few month I have had the same situation .
Later I found that this is happening not only with a particular destination , but also with most of the other destinations. Due to this I loss few customers , so now I'm in search for another good carrier who could cater the small & medium level providers like me.
