IPEVO SOLO is a Skype-embedded Internet phone that enables Internet calls without using a computer. However it could not login to Skype anymore. https://www.version-2.com/ipevo/en/support/download.php
Is it possible to install Zoiper to IPEVO SOLO to let it as a SIP phone?
Zoiper can be installed only on Android devices, but features such as the number pad will probably not work.
