Hi
The new SVersion 68.0.20 fixed the issue, now I can place calls from the Grandstream phones with no issues, I can reprovision and the configuration stayes on the devices.
One last question, Skyetel recomends using UDP, I've been using TCP with no issues with Callcentric but I want to migrate my clients to Skyetel, with Yealink phones TCP works fines on Skyetel network, Grandstream phones are working with UDP port 7853 after the new Vodia SV upadte, I don't know if I should keep using UDP or try to go back to TCP and default port 5060, I haven't tried this yet with the new SV 68.0.20. What you guys recomend?
Thank you
