SIP/Internet call problem after update to Android 5.1 on HTC One M9

[neilwhite]

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.

Have you tried a cache clear in recovery?

This is for the M8, but the steps should be the same; http://forums.androidcentral.com/ht...ow-reboot-into-stock-recovery-htc-one-m8.html

You will need to turn off fastboot in settings>battery, I believe.
