There is a way to do it without without complaining or blaming.
"exW, I am not sure if you realize it, but you keep answering the questions I am asking D. I know you are both excited for your fun times, but do you mind if I have a conversation alone with her?"
Or........ Since you have your D majority of the time and this will happen once in every blue moon and you know you can talk to her one on one when she gets home, you can drop it and not actually let it bother you, because its not worth it.
I, personally, have always let my D have her time with her father without phone calls. She has her own phone now (she is 10) and I don't need to go through ex. And I still let D10 be...... but it turns out she loves calling, facetiming me, and texting when she is at her dad's. Heck, I love it too, but I leave it to her to decide. I'll send a goodnight text, but I don't interrupt their time to together. And let me tell you, at 6 years old, I got a hi and and bye as did her father. he rarely called anyways.
I've got to say, though, you guys need a permanent parenting plan to avoid any confrontation, or confusion, or he said, she said. You make your time yours and her time hers.
