Important note: codec G729 must be bought separately.
It’s important for good voice quality.

Below you will see how to buy the mentioned codec.

Please note also that in Groundwire you can install few SIP accounts and for each SIP account the codec G729 must be bought separately, as well as the WiFi and 3G codec preferences must be set up, again separately for each account.

Codec G729

To buy the codec G729, go to Groundwire Settings.

Another important point to check is to make sure if for incoming calls you have option -> Use Push Notifications.

Then go to Add-ons

Click on -> G.729 Annex A Codec -> Buy on Google Play or on iTunes.

You are done!
