  • SIP over IPv6 just works


Tablets tend to not have a telephone app installed by the manufacturer. You'll need to install a SIP Phone app for Android. Popular apps include Zoiper, CSipSimple, and Linphone. If you are used to Grandstream hardware phones, they also have a 'GS Wave' SIP app for Android.

Of the above apps, only Linphone supports IPv6 (as of November 2018).
