We have exhausted any and all settings on the Bria app with ICON and it will not work consistently. They keep having "errors" show up in the error log. Then the sip stack stops working and Then we have to reset the system to get the ESNA back online. Interesting enough it ran for several months until last May when the Bria apps started updating on their iPhones. We ran wireshark and daiily error log dumps to ICON and they just said they will not support it at all. That is why we are wondering if anyone else had success with any other apps. I do not want to have the customer carrying around 2 phones all the time.
