Hello

Since updating my HTC One M9 to Android 5.1, I've been unable to make outgoing calls using SIP Internet calling as I did previously

When I tried to do it from my phone book I the call connects via the mobile network rather than as a data call.

At present I'm using the Zoiper app but prefer to return to the phones own client.

Any advice or help appreciated.
