I have a fairly new setup (2 months old) that I deployed. Over the course of two months I have had to go back several times because the phone system was not working ( no incoming or outgoing calls). When I log into the system the vlan is not responding. After I delete the interface and rebuild it, it usually works.
I have looked into network settings, firewall settings and asterisk sip settings but I can’t find any definitive answer.
Could it be hardware?
Thanks for the help!
