I have 50/50 custody with my ex Week to Week,  with a midweek visit. .Our court order says NTE 3 calls per week unless emergency.  My gripe is that I call my ex to speak to our son 6 and it always goes to voice mail and I leave a message telling my ex to have our son call me. My ex does have him call me back but I can never get a call back the same day  or on weekends he has him call me back days later..since we have no set times should I enforce this? To add ex  never calls our son during my time. .
