Ooma – It's at&ts fault

After being an Ooma customer for more than 20 years, I have decided to discontinue their service due to significant declines in performance over the past several years. While I have used the HD3 handset primarily for its two-line capability, I have found the overall quality lacking. Additionally, Ooma's Telo device no longer supports other phone systems like it used to, which has been a persistent issue.
Recently, I have experienced difficulty making outgoing calls, and was informed by technical support that the problem lies with AT&T users who have activated certain features on their phones. The recommended solution was for me to ask my contacts who use AT&T to disable this feature, which is neither practical nor feasible for reaching essential contacts such as healthcare providers.
Given these ongoing challenges, I have chosen to switch to 1VOIP, which offers competitive pricing, operates entirely within the USA, and provides 24-hour technical support. Based on my experience, I would recommend considering alternative providers like 1VOIP, which has also been recognized by PC Magazine. Thank you Ooma, your lack of service and poor explanations will no longer be tolerated.
