I had Vonage for over one year, and was very happy with them.
I had the 500 min package for $14.99.
Vonage raised the price to $17.99 which made me look around.
Found ITP for $9.99 for 500min. No brainer.
Took about 1 month to port my number from Vonage, was kept informed via email.
Vonage charged me $40.00 to cancel (if cancel before 2yrs) which is worth it.
ITP’s website is not as user friendly as Vonage but for $9.99 a month, I dont care.
Sound quality is very good and am happy to date.
