I pulled apart a Chinese 18650 charger to have a look. These were the problems found.
Is this the result of buying a cheap timer Chinese relay off Alliexpress?
I need a VoIP system for my grandmother that doesn’t cut-in and out. Currently I have a Cisco VoIP adaptor behind a Telstra Smart Modem Gen 2 (DJA0231). The problem that is happening is the phone is not clear and garbled, sometimes not being able to connect to the SIP server. I have theory that the modem is causing the connection problems, but I don’t necessarily want to replace the Telstra modem as it has 4G backup for DSL and voice. It also has VoIP, but being a Telstra branded modem, it is all locked down.
