The issue is most likely caused by your router/ network setup. The port for the RTP(audio stream) is probably being closed at some point.

You can take this guide as an example how you can forward the ports on your router: https://www.voipmechanic.com/port-forwarding-voip.htm

The default ports used by Zoiper5 are:

SIP port is random between 32000 - 65535TCP/ UDP
IAX port is 4569 UDP
RTP port is 8000 (+1 for every new line/ call) UDP
