I have a VoIP Phone at home with an ATA. Every thing is fine except when I reboot my VyOS router. I don’t know why but the port 5060 gets blocked so I have to change the SIP port on my ATA to 5080 to get the phone working again. The port 5060 get unblocked like 30 minutes after I change the port on my ATA.
Does anyone experience this issue before?
