How do you document phone refusal?

[Ref]

Mediation agreement states DH may contact SD between 8:30am and 8:30pm. DH is also supposed to get a response from messages "promptly" from either the child or mother.

Problem: BM is shutting the phone ringer and answering machine off. SD has been back at her mom's for over a week and DH only spoke with her for 5 minutes. He has left messages(2) when possible and told BM to have SD call him back directly.

How is something like this documented? It looks like a he said she said thing.

Has anyone used the parenting tracker or a manual method of recording and gotten a contempt charge?

Thanks folks

I know my cell phone bill on-line you can see an itemized list of all calls. If you get a machine you can tape it if your state allows this.  If you are still going back to court maybe you can ask for a specific time she will call you/or you call her (every Wed and Sun at 7:30) ......
