Not sure if I am having the same problem , anyway....

I am having trouble with incoming calls to rtcomm using gizmo5 as my service provider.
When a call comes in the device lights up, the rtcomm voice application automatically opens and the cpu spikes as you would expect , but the answer dialogue doesn't pop-up and the caller is told I am offline.

I have tested it with my voxalot number and that works perfectly.

Outgoing calls work fine.

Incoming and outgoing calls work fine if I use the gizmo5 softphone instead of rtcomm.

anyone else got this problem ?

update - I am now forwarding my gizmo5 number to voxalot and the incoming calls work fine that way ?! what a strange bug
