Kinda a rant about talking to someone while you are also on the phone talking

Elaina • Mother of 4 living children,2are my husbands,1 is mine and we finally had 1 together. When i was 18 i miscarried a child and 1/23/2015 our son was born sleeping
So on sundays i work a 12 hr shift so if i have time i call my husband and it seems like everytime i call we will be talking then he starts a conversation with his brother that is there. So i will just get off the phone because i dont want to fight and why stay on the phone when hes not even talking to me. Does anyone else feel its disrespectful to be having a conversation with someone while your on the phone with someone else ?
