Not saying it was crossed lines, but sometimes when you make a call it will be on a channel/frequency all phones share the ability to use the same frequencys.
However, when you make a call your phone seeks open channels and perhaps the channel it picked was occupied but when the phone decoded the channel it didn’t realize it was occupied as both phones may have simultaneously picked the same channel.
As you make a phone call when your phone says dialing then connected, for the first brief moment you are not supposed to hear anything but new phones are so fast to connect the call you may hear random sounds of occupied channels.
